WalkthroughThe pull request introduces multiple modifications across various components in an Angular application, primarily focusing on marking components as standalone. This allows them to function independently without being declared in a module. Additionally, several components have new imports added to their decorators, enhancing their modularity and functionality. The changes also include updates to input properties and the overall structure of components, maintaining existing logic while improving reusability. Changes

4-6: Consider enhancing the DialogData interfaceThe interface could be more descriptive about the expected slide reference format and any constraints.
Consider adding JSDoc comments and type constraints:
+/** + * Data interface for the enlarge slide image dialog + * @property slideToReference - Reference to the slide image (e.g., URL or identifier) + */ export interface DialogData { - slideToReference: string; + slideToReference: string; // Consider using a more specific type if possible }

1-13: Consider implementing OnDestroy for proper cleanupTo prevent potential memory leaks, it's recommended to implement cleanup logic for the dialog.
Consider implementing OnDestroy:
-import { Component, Inject } from '@angular/core'; +import { Component, Inject, OnDestroy } from '@angular/core'; import { MAT_DIALOG_DATA } from '@angular/material/dialog'; export interface DialogData { slideToReference: string; } @Component({ templateUrl: './enlarge-slide-image.component.html', standalone: true, }) -export class EnlargeSlideImageComponent { +export class EnlargeSlideImageComponent implements OnDestroy { constructor(@Inject(MAT_DIALOG_DATA) public data: DialogData) {} + + ngOnDestroy(): void { + // Cleanup any subscriptions or resources if needed + } }src/main/webapp/app/shared/metis/posting-button/posting-button.component.ts (2)
7-7: Document the reason for ESLint disable.Consider adding a brief comment explaining why the component-selector rule is disabled here.
- /* eslint-disable-next-line @angular-eslint/component-selector */ + /* eslint-disable-next-line @angular-eslint/component-selector -- Using attribute selector for button enhancement */
13-13: Add JSDoc documentation as per PR requirements.The PR objectives specify that TypeScript code should be documented using JSDoc style. Please add class-level documentation explaining the component's purpose and usage.
+/** + * A reusable button component that supports icons, labels, and loading states. + * Can be used as a primary or outlined button, with optional size variants. + * + * @example + * <button jhi-posting-button + * [buttonIcon]="icon" + * [buttonLabel]="'Submit'" + * [buttonLoading]="isLoading"> + * </button> + */ export class PostingButtonComponent {src/main/webapp/app/shared/metis/posting-thread/posting-thread.component.ts (1)

12-20: Consider enhancing JSDoc documentationThe documentation is well-structured, but could be enhanced with:
- Add
@sincetag to document the standalone migration- Include usage examples, especially important now that it's standalone
/** * Converts markdown used in posting content into html, sanitizes it and then declares it as safe to bypass further security. + * @since 1.x.x Converted to standalone pipe * @param {string} markdown the original markdown text * @param {boolean} contentBeforeReference to indicate if this is markdown content before a possible reference or after * @param {string[]} allowedHtmlTags to allow during sanitization * @param {string[]} allowedHtmlAttributes to allow during sanitization * @returns {string} the resulting html as a SafeHtml object that can be inserted into the angular template + * @example + * // In your standalone component: + * import { HtmlForPostingMarkdownPipe } from './html-for-posting-markdown.pipe'; + * + * @Component({ + * standalone: true, + * imports: [HtmlForPostingMarkdownPipe], + * template: '{{ markdownContent | htmlForPostingMarkdown }}' + * }) */src/main/webapp/app/shared/metis/posting-header/answer-post-header/answer-post-header.component.ts (1)
Line range hint
18-23: Consider memory leak prevention for EventEmitter.While the component structure is good, ensure that the
openPostingCreateEditModalEventEmitter is properly cleaned up when the component is destroyed. Consider implementing OnDestroy to handle cleanup.-export class AnswerPostHeaderComponent extends PostingHeaderDirective<AnswerPost> implements OnInit, OnChanges { +export class AnswerPostHeaderComponent extends PostingHeaderDirective<AnswerPost> implements OnInit, OnChanges, OnDestroy { @Input() isReadOnlyMode = false; @Input() lastReadDate?: dayjs.Dayjs; @Output() openPostingCreateEditModal = new EventEmitter<void>(); + + ngOnDestroy(): void { + this.openPostingCreateEditModal.complete(); + super.ngOnDestroy(); + }src/main/webapp/app/shared/link-preview/components/link-preview/link-preview.component.ts (2)

42-71: Enhance error handling and prevent memory leaksThe
removeLinkPreviewmethod has potential issues:
- Subscriptions are not being cleaned up, which could lead to memory leaks
- Missing error handling for HTTP calls
Consider applying this improvement:
removeLinkPreview(linkPreview: LinkPreview) { const urlToSearchFor = linkPreview.url; if (this.posting) { // Find all URL matches in the text (in the content of the post) let match; let modifiedContent = this.posting.content!; while ((match = urlRegex.exec(modifiedContent)) !== null) { const url = match[0]; const start = match.index; const end = start + url.length; if (url === urlToSearchFor || url.includes(urlToSearchFor)) { modifiedContent = modifiedContent.substring(0, start) + `<${url}>` + modifiedContent.substring(end); } } this.posting.content = modifiedContent; if (this.isReply) { - this.metisService.updateAnswerPost(this.posting).subscribe({ - next: () => {}, - }); + this.metisService.updateAnswerPost(this.posting).subscribe({ + next: () => { + console.log('Answer post updated successfully'); + }, + error: (error) => { + console.error('Failed to update answer post:', error); + // Consider adding user notification here + } + }); } else { - this.metisService.updatePost(this.posting).subscribe({ - next: () => {}, - }); + this.metisService.updatePost(this.posting).subscribe({ + next: () => { + console.log('Post updated successfully'); + }, + error: (error) => { + console.error('Failed to update post:', error); + // Consider adding user notification here + } + }); } } }Additionally, consider implementing the following:
- Store subscriptions in a class property
- Implement
OnDestroyand unsubscribe inngOnDestroy- Use the
takeUntiloperator with a destroy subject

17-25: Add JSDoc documentation for better code maintainabilityConsider adding JSDoc documentation for the component class and its input properties to improve code maintainability.
Add documentation like this:
+/** + * Component for displaying and managing link previews in posts and replies. + */ export class LinkPreviewComponent implements OnInit { + /** The link preview data to be displayed */ @Input() linkPreview: LinkPreview; + /** Flag indicating if loading progress should be shown */ @Input() showLoadingsProgress: boolean; + /** Flag indicating if the preview has finished loading */ @Input() loaded: boolean; + /** Flag indicating if an error occurred during preview loading */ @Input() hasError: boolean; + /** The posting associated with this preview */ @Input() posting?: Posting; + /** Flag indicating if this preview is in a reply context */ @Input() isReply?: boolean; + /** Flag indicating if multiple previews are allowed */ @Input() multiple?: boolean;src/main/webapp/app/shared/pipes/reacting-users-on-posting.pipe.ts (3)
Line range hint
23-30: Fix potential memory leak in transform methodThe subscription to
translateService.onLangChangeis never cleaned up, which could lead to memory leaks. The pipe instance might persist longer than expected, causing multiple subscriptions to accumulate.Consider using this implementation instead:
transform(reactingUsers: string[]): Observable<string> { - return new Observable((observer: any) => { - observer.next(this.updateReactingUsersString(reactingUsers)); - this.translateService.onLangChange.subscribe(() => { - observer.next(this.updateReactingUsersString(reactingUsers)); - }); - }); + return new Observable((observer) => { + observer.next(this.updateReactingUsersString(reactingUsers)); + const subscription = this.translateService.onLangChange.subscribe(() => { + observer.next(this.updateReactingUsersString(reactingUsers)); + }); + + // Clean up subscription when the observable is unsubscribed + return () => subscription.unsubscribe(); + });
Line range hint
23-23: Improve type safety by removing 'any' typeReplace the
anytype with the properObserver<string>type for better type safety.- return new Observable((observer: any) => { + return new Observable((observer: Observer<string>) => {Don't forget to add the import:
import { Observable, Observer } from 'rxjs';
Line range hint
35-65: Consider using type-safe translation keysWhile the internationalization implementation is good, consider using type-safe translation keys to prevent typos and make maintenance easier.
Create an interface for your translation keys:
interface MetisTranslations { 'artemisApp.metis.you': string; 'artemisApp.metis.reactedTooltip': string; 'artemisApp.metis.reactedTooltipTrimmed': string; 'artemisApp.metis.and': string; }Then use it with the translate service:

47-49: Consider implementing configurable link preview limitThe TODO comment indicates the need for a configurable limit. This should be implemented to improve flexibility at the course level.
Would you like me to help create a configuration service for managing these limits?
Line range hint
50-75: Potential race conditions and memory leaks in link preview handlingSeveral concerns in the link preview handling:
- Multiple concurrent subscriptions without proper cleanup
- Possible race conditions when updating linkPreviews array
- No error handling timeout for failed requests
Consider implementing these improvements:
private findPreviews() { const links: Link[] = this.linkifyService.find(this.data() ?? ''); - links + // Store subscription references for cleanup + this.subscriptions = links .filter((link) => !link.isLinkPreviewRemoved) .slice(0, 5) - .forEach((link) => { + .map((link) => this.linkPreviewService.fetchLink(link.href).subscribe({ next: (linkPreview) => { linkPreview.shouldPreviewBeShown = !!(linkPreview.url && linkPreview.title && linkPreview.description && linkPreview.image); - const existingLinkPreviewIndex = this.linkPreviews().findIndex((preview) => preview.url === linkPreview.url); - if (existingLinkPreviewIndex !== -1) { - this.linkPreviews.update((previews) => { - const existingLinkPreview = previews[existingLinkPreviewIndex]; - Object.assign(existingLinkPreview, linkPreview); - return previews; - }); - } else { - this.linkPreviews.set([...this.linkPreviews(), linkPreview]); - } + // Use atomic update to prevent race conditions + this.linkPreviews.update(previews => { + const existingIndex = previews.findIndex(preview => preview.url === linkPreview.url); + if (existingIndex !== -1) { + return previews.map((preview, index) => + index === existingIndex ? { ...preview, ...linkPreview } : preview + ); + } + return [...previews, linkPreview]; + }); this.hasError.set(false); this.loaded.set(true); this.showLoadingsProgress.set(false); this.multiple.set(this.linkPreviews().length > 1); }, + error: () => { + this.hasError.set(true); + this.showLoadingsProgress.set(false); + } }) - }); + ); }
Line range hint
77-79: Consider using identity-based trackingThe current tracking function might not be optimal if the URL is not unique or changes. Consider using a more stable identifier.
-trackLinks(index: number, preview: LinkPreview) { - return preview?.url; +trackLinks(_: number, preview: LinkPreview) { + return preview?.id ?? preview?.url; }src/main/webapp/app/shared/metis/message/message-reply-inline-input/message-reply-inline-input.component.ts (3)
Line range hint
22-27: Prevent potential memory leaks from EventEmitter.While the property declarations look good, consider implementing proper cleanup for the EventEmitter to prevent memory leaks.
Add this to prevent memory leaks:
+ import { Subject } from 'rxjs'; + import { takeUntil } from 'rxjs/operators'; export class MessageReplyInlineInputComponent extends PostingCreateEditDirective<AnswerPost> implements OnInit, OnChanges, OnDestroy { + private readonly destroy$ = new Subject<void>(); @Output() valueChange = new EventEmitter<void>(); + ngOnDestroy(): void { + this.destroy$.next(); + this.destroy$.complete(); + }
Line range hint
41-52: Improve type safety and simplify ngOnChanges logic.The current implementation of ngOnChanges could be more robust and simpler.
Consider this improved implementation:
- ngOnChanges(changes: SimpleChanges | void) { - if (this.formGroup && changes) { - for (const propName in changes) { - if (changes.hasOwnProperty(propName) && propName === 'posting') { - if (changes['posting'].previousValue?.post?.id === changes['posting'].currentValue?.post?.id) { - this.posting.content = this.formGroup.get('content')?.value; - } - } - } - } - super.ngOnChanges(); - } + ngOnChanges(changes: SimpleChanges): void { + if (this.formGroup && changes?.['posting']) { + const postingChange = changes['posting']; + if (postingChange.previousValue?.post?.id === postingChange.currentValue?.post?.id) { + this.posting.content = this.formGroup.get('content')?.value ?? ''; + } + } + super.ngOnChanges(); + }
Line range hint
71-99: Improve subscription management and error handling.The current implementation of createPosting and updatePosting methods could benefit from better subscription management and error handling.
Consider these improvements:
createPosting(): void { this.posting.content = this.formGroup.get('content')?.value; this.metisService.createAnswerPost(this.posting).subscribe({ next: (answerPost: AnswerPost) => { this.resetFormGroup(''); this.isLoading = false; this.onCreate.emit(answerPost); }, - error: () => { + error: (error: Error) => { this.isLoading = false; + console.error('Failed to create answer post:', error); + // TODO: Add user-friendly error handling }, - }); + }).pipe(takeUntil(this.destroy$)); } updatePosting(): void { this.posting.content = this.formGroup.get('content')?.value; this.metisService.updateAnswerPost(this.posting).subscribe({ next: () => { this.isLoading = false; }, - error: () => { + error: (error: Error) => { this.isLoading = false; + console.error('Failed to update answer post:', error); + // TODO: Add user-friendly error handling }, - }); + }).pipe(takeUntil(this.destroy$)); }src/main/webapp/app/shared/metis/posting-create-edit-modal/answer-post-create-edit-modal/answer-post-create-edit-modal.component.ts (1)
Line range hint
21-108: Consider enhancing subscription management and error handling.While the implementation is solid, consider these improvements:
Subscription Management:
- Consider implementing OnDestroy to clean up subscriptions
- Use takeUntil pattern for subscription management
Error Handling:
- Add specific error handling instead of just setting isLoading to false
- Consider showing user-friendly error messages
Here's a suggested implementation:
+ import { Subject } from 'rxjs'; + import { takeUntil } from 'rxjs/operators'; export class AnswerPostCreateEditModalComponent extends PostingCreateEditModalDirective<AnswerPost> { + private destroy$ = new Subject<void>(); + // ... existing code ... + + ngOnDestroy(): void { + this.destroy$.next(); + this.destroy$.complete(); + } createPosting(): void { this.posting.content = this.formGroup.get('content')?.value; - this.metisService.createAnswerPost(this.posting).subscribe({ + this.metisService.createAnswerPost(this.posting).pipe( + takeUntil(this.destroy$) + ).subscribe({ next: (answerPost: AnswerPost) => { this.resetFormGroup(); this.isLoading = false; this.onCreate.emit(answerPost); this.createEditAnswerPostContainerRef?.clear(); }, - error: () => { + error: (error) => { this.isLoading = false; + console.error('Failed to create answer post:', error); + // TODO: Add user-friendly error handling }, }); }src/main/webapp/app/shared/metis/posting-create-edit-modal/post-create-edit-modal/post-tag-selector/post-tag-selector.component.ts (2)
18-19: Consider lazy loading Material modules for better performance.While the standalone component setup is correct, the direct import of multiple Material modules could impact initial load time. Consider lazy loading these modules, especially if they're not immediately needed on component initialization.
Example implementation:
@Component({ selector: 'jhi-post-tag-selector', templateUrl: './post-tag-selector.component.html', styleUrls: ['./post-tag-selector.component.scss'], standalone: true, - imports: [MatChipsModule, MatAutocompleteModule, MatSelectModule, MatFormFieldModule, MatDialogModule, ArtemisSharedModule], + imports: [ + ArtemisSharedModule, + // Lazy load Material modules + forwardRef(() => MatChipsModule), + forwardRef(() => MatAutocompleteModule), + forwardRef(() => MatSelectModule), + forwardRef(() => MatFormFieldModule), + forwardRef(() => MatDialogModule), + ], })Don't forget to add the import:
import { forwardRef } from '@angular/core';
Line range hint
21-116: Consider using takeUntil pattern for subscription management.While the current subscription cleanup in ngOnDestroy is functional, consider using the takeUntil pattern for more robust subscription management, especially if more subscriptions are added in the future.
Example implementation:
export class PostTagSelectorComponent implements OnInit, OnChanges, OnDestroy, AfterContentChecked { private readonly destroy$ = new Subject<void>(); ngOnInit(): void { this.metisService.tags.pipe( takeUntil(this.destroy$) ).subscribe((tags: string[]) => { this.existingPostTags = this.tagCtrl.valueChanges.pipe( takeUntil(this.destroy$), startWith(undefined), map((category: string | undefined) => (category ? this._filter(category) : tags.slice()) ), ); }); this.tags = this.postTags ? this.postTags : []; } ngOnDestroy(): void { this.destroy$.next(); this.destroy$.complete(); } }Don't forget to add the imports:
import { Subject } from 'rxjs'; import { takeUntil } from 'rxjs/operators';src/main/webapp/app/shared/metis/posting-reactions-bar/answer-post-reactions-bar/answer-post-reactions-bar.component.ts (3)
8-13: Consider reorganizing imports per Angular style guideWhile the imports are correct, consider reorganizing them according to the Angular style guide:
- Angular imports
- Third-party imports
- Application imports
+import { OverlayModule } from '@angular/cdk/overlay'; + import { ReactingUsersOnPostingPipe } from 'app/shared/pipes/reacting-users-on-posting.pipe'; import { EmojiComponent } from 'app/shared/metis/emoji/emoji.component'; import { ArtemisSharedModule } from 'app/shared/shared.module'; import { ArtemisConfirmIconModule } from 'app/shared/confirm-icon/confirm-icon.module'; import { EmojiPickerComponent } from 'app/shared/metis/emoji/emoji-picker.component'; -import { OverlayModule } from '@angular/cdk/overlay';

109-114: Prevent potential memory leak in subscriptionThe subscription to
updateAnswerPostshould be cleaned up to prevent memory leaks.toggleResolvesPost(): void { if (this.isAtLeastTutorInCourse || this.isAuthorOfOriginalPost) { this.posting.resolvesPost = !this.posting.resolvesPost; - this.metisService.updateAnswerPost(this.posting).subscribe(); + this.metisService.updateAnswerPost(this.posting) + .subscribe({ + next: () => this.postingUpdated.emit(), + error: (error) => console.error('Failed to update answer post', error) + }); } }
Line range hint
82-92: Improve code readability and null safety in setMayDeleteThe complex boolean logic could be simplified and null checks added for better maintainability.
setMayDelete(): void { + const post = this.posting?.post; + if (!post) { + this.mayDelete = false; + this.mayDeleteOutput.emit(false); + return; + } + - this.isAuthorOfOriginalPost = this.metisService.metisUserIsAuthorOfPosting(this.posting.post!); - this.isAnswerOfAnnouncement = getAsChannelDTO(this.posting.post?.conversation)?.isAnnouncementChannel ?? false; - const isCourseWideChannel = getAsChannelDTO(this.posting.post?.conversation)?.isCourseWide ?? false; + this.isAuthorOfOriginalPost = this.metisService.metisUserIsAuthorOfPosting(post); + const channel = getAsChannelDTO(post.conversation); + this.isAnswerOfAnnouncement = channel?.isAnnouncementChannel ?? false; + const isCourseWideChannel = channel?.isCourseWide ?? false; const isAtLeastInstructorInCourse = this.metisService.metisUserIsAtLeastInstructorInCourse(); - const mayEditOrDeleteOtherUsersAnswer = - (isCourseWideChannel && isAtLeastInstructorInCourse) || (getAsChannelDTO(this.metisService.getCurrentConversation())?.hasChannelModerationRights ?? false); + const hasModeratorRights = getAsChannelDTO(this.metisService.getCurrentConversation())?.hasChannelModerationRights ?? false; + const mayEditOrDeleteOtherUsersAnswer = (isCourseWideChannel && isAtLeastInstructorInCourse) || hasModeratorRights; this.mayDelete = !this.isReadOnlyMode && (this.isAuthorOfPosting || mayEditOrDeleteOtherUsersAnswer); this.mayDeleteOutput.emit(this.mayDelete); }src/main/webapp/app/shared/metis/posting-content/posting-content-part/posting-content-part.components.ts (1)
31-32: Consider breaking down the component for better maintainability.The component has multiple responsibilities (handling files, dialogs, references, icons). Consider:
- Extracting file handling logic into a separate component
- Creating a dedicated component for reference handling
- Moving icon mapping to a separate service
This would improve:
- Code maintainability
- Component reusability
- Testing isolation
Example refactor for icon handling:
// reference-icon.service.ts @Injectable({ providedIn: 'root' }) export class ReferenceIconService { getIcon(reference: ReferenceType): IconProp { // Move icon mapping logic here } }// posting-content-part.component.ts export class PostingContentPartComponent { constructor( private referenceIconService: ReferenceIconService, // other dependencies ) {} referenceIcon(reference: ReferenceType): IconProp { return this.referenceIconService.getIcon(reference); } }src/main/webapp/app/shared/metis/metis.module.ts (2)
55-63: Consider organizing standalone components by featureThe direct import of standalone components like
PostReactionsBarComponent,AnswerPostReactionsBarComponent, etc., while maintaining them in exports could lead to maintenance challenges. Consider organizing these components into feature modules for better maintainability.Consider creating feature modules like:
- PostingModule (for post-related components)
- ReactionsModule (for reaction-related components)
- EditorModule (for editor-related components)
This would improve code organization and make the dependencies clearer.
Line range hint
1-119: Consider breaking down MetisModule into smaller feature modulesThe MetisModule has grown quite large and handles multiple concerns (posts, reactions, editors, etc.). While the migration to standalone components is a good step, consider further improvements:
Split into feature modules:
- MetisPostingModule
- MetisReactionsModule
- MetisEditorModule
- MetisMessageModule
Create a MetisSharedModule for common components
This would:
- Improve maintainability
- Enable lazy loading
- Make dependencies clearer
- Facilitate testing
Would you like assistance in planning this modular architecture?
src/main/webapp/app/shared/metis/posting-footer/post-footer/post-footer.component.ts (2)
35-36: Consider optimizing shared module imports.Instead of importing the entire
ArtemisSharedModule, consider importing only the specific components and directives needed from the shared module. This can help reduce the bundle size.
Potential memory leak in change detection and ViewChild references
The component has several potential memory leak sources that aren't properly cleaned up in
ngOnDestroy:
changeDetector.detectChanges()is called inngAfterContentCheckedbut the reference isn't cleaned up- Multiple
@Output()EventEmitters (openThread,userReferenceClicked,channelReferenceClicked) aren't unsubscribed- Multiple
@ViewChildreferences that should be nullified on destroy- The component extends
PostingFooterDirectivewhich might have its own resources to clean upRecommended cleanup in
ngOnDestroy:ngOnDestroy(): void { this.answerPostCreateEditModal?.createEditAnswerPostContainerRef?.clear(); this.openThread.complete(); this.userReferenceClicked.complete(); this.channelReferenceClicked.complete(); this.containerRef?.clear(); this.answerPostCreateEditModal = undefined; this.createAnswerPostModalComponent = undefined; }🔗 Analysis chain
Line range hint
89-91: Verify: Ensure complete cleanup in ngOnDestroy.The component cleans up the modal reference, but please verify if there are any other subscriptions or event listeners that need cleanup:

The lowercase version appears to be unused and should be removed.import { AfterContentChecked, ChangeDetectionStrategy, ChangeDetectorRef, Component, EventEmitter, HostListener, Inject, Input, OnChanges, OnInit, Output, Renderer2, ViewChild, ViewContainerRef, - input, } from '@angular/core';
55-66: Fix indentation in imports arrayThe imports array indentation should follow the 4-space rule as per coding guidelines.

187-190: Avoid manual change detection in lifecycle hooksUsing
changeDetector.detectChanges()inngAfterContentCheckedcan lead to performance issues and infinite change detection loops.Consider using
ChangeDetectionStrategy.OnPushwith explicit change detection triggers or async pipe in template instead of manual change detection.

156-166: Replace direct DOM manipulation with CSS classesDirect DOM manipulation for scroll handling should be replaced with CSS classes for better performance and maintainability.

31-31: Avoid importing modules in standalone componentsImporting
ArtemisSharedModuleon line 31 into a standalone component may include unnecessary code and affect tree-shaking.Consider importing only the required components, directives, and pipes from
ArtemisSharedModuledirectly into yourimportsarray. This optimizes bundle size and adheres to the standalone component paradigm.Example:
- import { ArtemisSharedModule } from 'app/shared/shared.module';Then, add the necessary components to your imports:
imports: [ // Other imports... // Add specific components, directives, or pipes needed from ArtemisSharedModule ],
Line range hint
12-12: Remove invalid import{ input }from@angular/coreThe import
{ input }does not exist in@angular/core. This can cause runtime errors.Apply this diff to remove the invalid import:
- import { ..., Input, ..., input } from '@angular/core'; + import { ..., Input, ... } from '@angular/core';
Line range hint
64-64: Use@Input()decorator for input propertyisConsecutiveThe property
isConsecutiveis incorrectly assigned usinginput<boolean>(false);. Instead, use the@Input()decorator to properly declare it as an input property.Apply this diff to fix the issue:
- isConsecutive = input<boolean>(false); + @Input() + isConsecutive = false;This change ensures that
isConsecutiveis correctly recognized as an input property by Angular.src/main/webapp/app/shared/metis/posting-content/posting-content.components.ts (4)
Line range hint
1-1: Ensure Consistent Usage of Inputs and OutputsThe component mixes traditional
@Input()and@Output()decorators with the newinput()andoutput()functions from Angular Signals. For clarity and maintainability, consider using a consistent approach throughout the component.To standardize, you can convert existing
@Input()and@Output()properties to useinput()andoutput(), or revert to using@Input()and@Output()decorators for all inputs and outputs.
11-14: Replace Module Imports with Specific Component ImportsIn standalone components, it's recommended to import only the necessary components, directives, and pipes directly instead of entire modules. This improves tree-shaking and reduces bundle size.
Consider importing specific components and directives used in your template:
-import { ArtemisSharedComponentModule } from 'app/shared/components/shared-component.module'; -import { ArtemisSharedModule } from 'app/shared/shared.module'; +import { FaIconComponent } from '@fortawesome/angular-fontawesome'; +import { HtmlForMarkdownPipe } from 'app/shared/pipes/html-for-markdown.pipe'; +import { TranslateDirective } from 'app/shared/language/translate.directive'; import { LinkPreviewContainerComponent } from 'app/shared/link-preview/components/link-preview-container/link-preview-container.component'; import { PostingContentPartComponent } from 'app/shared/metis/posting-content/posting-content-part/posting-content-part.components'; @Component({ // ... imports: [ + FaIconComponent, + HtmlForMarkdownPipe, + TranslateDirective, LinkPreviewContainerComponent, PostingContentPartComponent, ], })
Line range hint
23-27: Access Input Signals CorrectlyWhen using the
input()function from Angular Signals, the property becomes a signal and should be accessed by invoking it as a function. Ensure you're consistently accessing these properties usingthis.propertyName().For example, when checking
isSubscribeToMetis, use:if (!this.isSubscribeToMetis()) { ... }Review all usages of
input()properties to ensure they are accessed correctly.
Line range hint
53-57: Inconsistent Logic inngOnChangesMethodThe logic in
ngOnChangesdiffers from that inngOnInit. InngOnInit, whenisSubscribeToMetisisfalse, you callcomputePostingContentParts, but inngOnChanges, you callcomputeContentPartsOfPostswhenisSubscribeToMetisisfalse. This may lead to unexpected behavior.Consider updating
ngOnChangesto align withngOnInit:ngOnChanges(): void { if (!this.isSubscribeToMetis()) { + const patternMatches: PatternMatch[] = this.getPatternMatches(); + this.computePostingContentParts(patternMatches); } else { this.computeContentPartsOfPosts(); } }

10-10: 🛠️ Refactor suggestion
Verify standalone component dependencies
While marking the component as standalone is correct, we need to ensure all required dependencies are properly imported in the imports array of the @component decorator.
Apply this diff to add the necessary imports:
@Component({
templateUrl: './enlarge-slide-image.component.html',
standalone: true,
+ imports: [
+ // Add Material Dialog modules if using any in the template
+ // Example: MatDialogModule, MatButtonModule, etc.
+ ],
})✅ Verification successful
No additional imports needed for this standalone component
The component is correctly configured as standalone and only needs MAT_DIALOG_DATA injection token which is already properly imported. The template is simple, only using standard HTML elements (div and img) with Angular's built-in property bindings, requiring no additional imports.
- Template uses only basic HTML elements and Angular's built-in bindings (
[style],[src]) - Component already imports the necessary
MAT_DIALOG_DATAfrom@angular/material/dialog - No Material Dialog UI components are used in the template

4-4: Verify template dependencies are complete
The PostComponent import has been added for standalone mode, but we should verify if there are other components used in the template that need to be imported.
✅ Verification successful
Import dependencies are correctly configured
The template only uses the jhi-post selector which corresponds to the imported PostComponent (verified selector: 'jhi-post'). No additional component dependencies need to be imported.

11-12: Verify parent component/module registration
The standalone configuration looks good. Since this is part of the Metis migration, ensure this component is properly imported where it's being used.
✅ Verification successful
Component registration is properly handled
The PostingThreadComponent is correctly used in its standalone configuration:
- It's properly imported in discussion-section.component.html and conversation-messages.component.ts
- It's being removed from MetisModule's declarations and moved to imports, which is the correct pattern for standalone components
- All components using it are importing it directly in their imports array

12-13: Successfully migrated to standalone component
The component has been correctly configured as standalone with the necessary imports. This change aligns with the PR objective of migrating to standalone components and follows Angular's best practices.
Line range hint 15-31: Implementation follows Angular best practices
The component demonstrates good practices:
- Proper use of dependency injection with
inject - Well-typed inputs/outputs
- Effective use of computed properties
- Follows naming conventions (camelCase for methods/properties)
5-7: Consider optimizing shared module imports
While the imports are correctly added for standalone component support, importing the entire ArtemisSharedModule might bring unnecessary dependencies. Consider importing only the required components/directives from the shared module to optimize bundle size.
Let's check what's actually used from the shared module:
src/main/webapp/app/shared/pipes/html-for-posting-markdown.pipe.ts (1)
5-8: Verify standalone pipe usage across the application
The migration to standalone pipe looks correct. However, we should verify that all components using this pipe have properly imported it.
✅ Verification successful
Migration to standalone pipe is correctly implemented
The verification shows that:
- The component using the pipe (PostingContentPartComponent) is already a standalone component
- The pipe is properly imported in the component's imports array
- The pipe is used in the component's template
- The implementation follows Angular's standalone migration guidelines

The new imports are correctly structured and necessary for the standalone component migration.
14-15: Verify standalone status of imported components.
The standalone configuration looks correct. However, we should ensure that all imported components (ProfilePictureComponent, EmojiPickerComponent) are also marked as standalone components.
✅ Verification successful
Let me try a different approach to verify the standalone status of these components.
Let me try one more time with a corrected regex pattern.
All imported components are properly configured as standalone
Both ProfilePictureComponent and EmojiPickerComponent are correctly marked as standalone components, which is consistent with the Angular standalone migration requirements. The verification confirms that the component configuration is correct and follows best practices.

Component dependencies are properly configured and no circular dependencies detected
Based on the analysis:
- The template uses
jhi-posting-markdown-editorandjhi-posting-buttoncomponents, which are correctly imported viaPostingMarkdownEditorComponentandPostingButtonComponent ArtemisSharedModuleis imported which provides the common Angular directives and pipes used in the template (form directives, translate pipe)- The component is imported by other components (
PostFooterComponent,PostComponent,AnswerPostComponent) but only as a child component reference, not creating any circular dependencies - The component is registered in
metis.module.tsbut only as a declaration, which is fine for standalone components

Migration to standalone component is incomplete - component is still declared in MetisModule

💡 Codebase verification
Based on the template content and shared module analysis, I can now provide a final response:
Consider importing specific components instead of ArtemisSharedModule
Looking at the template and shared module content, your component only uses:
- ngIf/ngClass directives (from CommonModule)
- ngbTooltip (from NgbModule)
- jhiTranslate directive and artemisTranslate pipe (from SharedCommonModule)
- fa-icon (already imported via FontAwesomeModule)
Instead of importing the entire ArtemisSharedModule, import just these specific dependencies:
imports: [
ProfilePictureComponent,
FontAwesomeModule,
CommonModule,
NgbTooltipModule,
TranslateModule,
ArtemisSharedCommonModule
]🔗 Analysis chain
Verify shared module import in standalone component
While the imports for ProfilePictureComponent and FontAwesomeModule are appropriate, importing the entire ArtemisSharedModule in a standalone component might lead to circular dependencies. Consider importing only the specific components/directives needed from the shared module.

💡 Codebase verification
Consider selective imports and encapsulation changes
-
The component is importing the entire ArtemisSharedModule but only needs the common Angular features which are already available through standalone imports. The shared module can be removed as PostingButtonComponent and PostingMarkdownEditorComponent are already imported separately.
-
The component uses ViewEncapsulation.None which can lead to style leaks. Given the presence of a dedicated SCSS file (message-inline-input.component.scss), the component should use the default encapsulation mode to properly scope its styles.
- Remove
ArtemisSharedModulefrom imports as it's not needed in standalone components - Change
encapsulation: ViewEncapsulation.Noneto use default encapsulation or explicitly set it toViewEncapsulation.Emulated
🔗 Analysis chain
Verify shared module imports and encapsulation.
Two considerations:
- Consider importing only the needed components/directives from ArtemisSharedModule to reduce bundle size
- Using ViewEncapsulation.None might lead to style leaks. Ensure styles are properly scoped.

Potential issues with component dependencies
Based on the verification results:
- EmojiComponent and EmojiPickerComponent are properly configured as standalone components
- ReactingUsersOnPostingPipe appears to be a pipe, not a component (missing @component decorator)
- ArtemisSharedModule and ArtemisConfirmIconModule are NgModules that may contain dependencies needed by the standalone component
The component imports need to be adjusted:
- ReactingUsersOnPostingPipe should be imported directly from the pipes module
- Consider importing only necessary components from ArtemisSharedModule instead of the entire module

Redundant export of standalone pipe confirmed
The pipe is correctly marked as standalone and is being directly imported from its source file (app/shared/pipes/reacting-users-on-posting.pipe) by the components that use it. There's no usage through the metis.module, making its export redundant.
- Remove
ReactingUsersOnPostingPipefrom the exports array insrc/main/webapp/app/shared/metis/metis.module.ts
🔗 Analysis chain
Review necessity of exporting standalone pipe

13-15: Consider enhancing type safety and documentation.A few suggestions to improve the code:
- Add explicit generic type to EventEmitter
- Add JSDoc comments to abstract methods
-@Output() onCreate: EventEmitter<T> = new EventEmitter<T>(); -@Output() isModalOpen = new EventEmitter<void>(); +@Output() onCreate = new EventEmitter<T>(); +@Output() isModalOpen = new EventEmitter<void>(); +/** Resets the form group to its initial state */ abstract resetFormGroup(): void; +/** Creates a new posting entity */ abstract createPosting(): void; +/** Updates an existing posting entity */ abstract updatePosting(): void;
Line range hint
10-11: Consider externalizing the max content length constant.The max content length constant could be moved to a shared configuration file since it needs to match the Java backend.
Consider creating a shared constants file:
// src/main/webapp/app/shared/constants/posting.constants.ts export const POSTING_CONSTRAINTS = { MAX_CONTENT_LENGTH: 5000, } as const;src/main/webapp/app/shared/metis/message/message-reply-inline-input/message-reply-inline-input.component.ts (3)
1-1: Consider grouping related imports togetherWhile the imports are valid, consider organizing them into logical groups:
- Angular core imports
- Feature/component imports
- Model/interface imports
- Utility imports
- import { Component, EventEmitter, OnChanges, OnInit, Output, SimpleChanges, ViewEncapsulation, inject, input } from '@angular/core'; - import { AnswerPost } from 'app/entities/metis/answer-post.model'; - import { Validators } from '@angular/forms'; - import { PostContentValidationPattern } from 'app/shared/metis/metis.util'; - import { PostingCreateEditDirective } from 'app/shared/metis/posting-create-edit.directive'; - import { LocalStorageService } from 'ngx-webstorage'; - import { ConversationDTO } from 'app/entities/metis/conversation/conversation.model'; - import { PostingButtonComponent } from 'app/shared/metis/posting-button/posting-button.component'; - import { ArtemisSharedModule } from 'app/shared/shared.module'; - import { PostingMarkdownEditorComponent } from 'app/shared/metis/posting-markdown-editor/posting-markdown-editor.component'; + // Angular imports + import { Component, EventEmitter, OnChanges, OnInit, Output, SimpleChanges, ViewEncapsulation, inject, input } from '@angular/core'; + import { Validators } from '@angular/forms'; + + // Third-party imports + import { LocalStorageService } from 'ngx-webstorage'; + + // Feature components + import { PostingButtonComponent } from 'app/shared/metis/posting-button/posting-button.component'; + import { PostingMarkdownEditorComponent } from 'app/shared/metis/posting-markdown-editor/posting-markdown-editor.component'; + import { ArtemisSharedModule } from 'app/shared/shared.module'; + + // Models and utilities + import { AnswerPost } from 'app/entities/metis/answer-post.model'; + import { ConversationDTO } from 'app/entities/metis/conversation/conversation.model'; + import { PostContentValidationPattern } from 'app/shared/metis/metis.util'; + import { PostingCreateEditDirective } from 'app/shared/metis/posting-create-edit.directive';Also applies to: 8-10
Line range hint
36-47: Improve type safety in ngOnChangesThe current implementation uses string indexing which could be unsafe. Consider using type-safe alternatives.
ngOnChanges(changes: SimpleChanges | void) { if (this.formGroup && changes) { - for (const propName in changes) { - if (changes.hasOwnProperty(propName) && propName === 'posting') { - if (changes['posting'].previousValue?.post?.id === changes['posting'].currentValue?.post?.id) { + if ('posting' in changes) { + const postingChange = changes['posting']; + if (postingChange.previousValue?.post?.id === postingChange.currentValue?.post?.id) { this.posting.content = this.formGroup.get('content')?.value; - } } } } super.ngOnChanges(); }
Line range hint
71-84: Enhance error handling in createPostingThe error handling could be improved by providing more specific error feedback to users.
createPosting(): void { this.posting.content = this.formGroup.get('content')?.value; this.metisService.createAnswerPost(this.posting).subscribe({ next: (answerPost: AnswerPost) => { this.resetFormGroup(''); this.isLoading = false; this.onCreate.emit(answerPost); }, - error: () => { + error: (error) => { this.isLoading = false; + // Handle specific error cases + const errorMessage = error.status === 403 ? 'Permission denied' : 'Failed to create post'; + // Emit error to parent or handle locally + this.onError.emit(errorMessage); }, }); }src/main/webapp/app/shared/metis/posting-create-edit-modal/answer-post-create-edit-modal/answer-post-create-edit-modal.component.ts (2)
Line range hint
28-33: Prevent potential memory leaks in ViewContainerRef usageWhile the ViewContainerRef usage is correct, ensure proper cleanup by implementing OnDestroy.
Add the following implementation:
- export class AnswerPostCreateEditModalComponent extends PostingCreateEditModalDirective<AnswerPost> { + export class AnswerPostCreateEditModalComponent extends PostingCreateEditModalDirective<AnswerPost> implements OnDestroy { + ngOnDestroy(): void { + this.close(); + }Also, add OnDestroy to the imports:
- import { Component, EventEmitter, Input, Output, ViewContainerRef, ViewEncapsulation } from '@angular/core'; + import { Component, EventEmitter, Input, Output, ViewContainerRef, ViewEncapsulation, OnDestroy } from '@angular/core';Also applies to: 37-41
Line range hint
52-67: Enhance error handling with user feedbackThe error handling in
createPostingandupdatePostingmethods only resets the loading state without informing the user about the failure.Consider adding error notifications:
error: () => { this.isLoading = false; + // Use your application's notification service + this.notificationService.showError('artemisApp.metis.error.saveFailed'); },Don't forget to inject the notification service in the constructor.
Also applies to: 74-89

1-19: LGTM! Component is properly configured as standaloneThe component configuration follows Angular's standalone component pattern, enabling better lazy loading capabilities. The imports are correctly specified in the component decorator.
Consider organizing imports by grouping them:
- Angular core
- Angular material
- Third-party libraries
- Application imports
Line range hint
21-38: Add explicit type declarations for better type safetyWhile the code follows naming conventions, some properties could benefit from explicit type declarations.
Consider applying these type improvements:
- existingPostTags: Observable<string[]>; - tags: string[]; + existingPostTags!: Observable<string[]>; + tags: string[] = []; - tagInput: ElementRef<HTMLInputElement>; + tagInput!: ElementRef<HTMLInputElement>;
Line range hint
46-54: Consider protecting against potential race conditionsThe subscription setup in
ngOnInitcould be vulnerable to race conditions ifmetisService.tagsemits before the component is fully initialized.Consider using
combineLatestor ensuring proper initialization:ngOnInit(): void { - this.tagsSubscription = this.metisService.tags.subscribe((tags: string[]) => { + this.tagsSubscription = this.metisService.tags.pipe( + startWith([]) + ).subscribe((tags: string[]) => { this.existingPostTags = this.tagCtrl.valueChanges.pipe( startWith(undefined), map((category: string | undefined) => (category ? this._filter(category) : tags.slice())), ); }); this.tags = this.postTags ? this.postTags : []; }
Line range hint
82-95: Extract magic number to a constantThe tag limit of 3 is hardcoded in multiple places. This should be extracted to a constant for better maintainability.
Consider adding a constant:
+ private static readonly MAX_TAGS = 3; onItemAdd(event: MatChipInputEvent) { const tagString = (event.value || '').trim(); // also test for duplicated tag - if (tagString && !this.tags?.includes(tagString) && this.tags?.length < 3) { + if (tagString && !this.tags?.includes(tagString) && this.tags?.length < PostTagSelectorComponent.MAX_TAGS) {
Line range hint
114-116: Enhance subscription cleanupWhile the component does unsubscribe in
ngOnDestroy, it's good practice to use a cleanup subject for all observables.Consider using a destroy subject:
+ private readonly destroy$ = new Subject<void>(); ngOnInit(): void { - this.tagsSubscription = this.metisService.tags.subscribe(...); + this.tagsSubscription = this.metisService.tags.pipe( + takeUntil(this.destroy$) + ).subscribe(...); } ngOnDestroy(): void { - this.tagsSubscription.unsubscribe(); + this.destroy$.next(); + this.destroy$.complete(); }src/main/webapp/app/shared/metis/answer-post/answer-post.component.ts (1)
Line range hint
108-124: Consider extracting scroll manipulation logic to a serviceThe
disableBodyScrollandenableBodyScrollmethods manipulate DOM directly. Consider extracting this logic into a shared service for better reusability and maintainability.// Suggested service: ScrollManipulationService @Injectable({ providedIn: 'root' }) export class ScrollManipulationService { constructor( private renderer: Renderer2, @Inject(DOCUMENT) private document: Document ) {} disableBodyScroll(selector: string) { const container = this.document.querySelector(selector); if (container) { this.renderer.setStyle(container, 'overflow', 'hidden'); } } enableBodyScroll(selector: string) { const container = this.document.querySelector(selector); if (container) { this.renderer.setStyle(container, 'overflow-y', 'auto'); } } }src/main/webapp/app/shared/metis/posting-footer/post-footer/post-footer.component.ts (2)
36-37: Consider optimizing imports for better lazy loadingWhile the standalone component setup is correct, importing the entire
ArtemisSharedModulemight impact lazy loading. Consider importing only the specific components and directives needed from the shared module.Example approach:
-imports: [AnswerPostCreateEditModalComponent, AnswerPostComponent, ArtemisSharedModule], +imports: [ + AnswerPostCreateEditModalComponent, + AnswerPostComponent, + // Import specific items from ArtemisSharedModule instead of the entire module + // Example: CommonModule, FormsModule, specific pipes or directives +],
Line range hint
108-146: Improve type safety and change detection in groupAnswerPosts methodThe current implementation has two areas for improvement:
- Uses 'any' type for date manipulation
- Contains multiple manual change detection calls
Consider this type-safe implementation:
+interface PostWithDate extends AnswerPost { + creationDateDayjs?: dayjs.Dayjs; +} groupAnswerPosts(): void { if (!this.sortedAnswerPosts || this.sortedAnswerPosts.length === 0) { this.groupedAnswerPosts = []; return; } - this.sortedAnswerPosts = this.sortedAnswerPosts + const typedPosts: PostWithDate[] = this.sortedAnswerPosts .slice() .reverse() .map((post) => ({ + ...post, creationDateDayjs: post.creationDate ? dayjs(post.creationDate) : undefined, - return post; })); - const sortedPosts = this.sortedAnswerPosts.sort((a, b) => { - const aDate = (a as any).creationDateDayjs; - const bDate = (b as any).creationDateDayjs; + const sortedPosts = typedPosts.sort((a, b) => { + const aDate = a.creationDateDayjs; + const bDate = b.creationDateDayjs; return aDate?.valueOf() - bDate?.valueOf(); }); // ... rest of the method ... - this.changeDetector.detectChanges(); // Remove this call as it's handled in ngOnChangessrc/main/webapp/app/shared/metis/posting-reactions-bar/posting-reactions-bar.directive.ts (4)
Line range hint
52-54: Standardize output property declarations.There's an inconsistency in how output properties are declared:
- Some use the new
output<T>()function- Others use the traditional
@Output() = new EventEmitter<T>()For consistency and maintainability, consider standardizing all output declarations to use the new
output<T>()function.Apply this diff to standardize the output declarations:
-@Output() openPostingCreateEditModal = new EventEmitter<void>(); -@Output() reactionsUpdated = new EventEmitter<Reaction[]>(); -@Output() isModalOpen = new EventEmitter<void>(); +readonly openPostingCreateEditModal = output<void>(); +readonly reactionsUpdated = output<Reaction[]>(); +readonly isModalOpen = output<void>();Also applies to: 64-65
Line range hint
156-170: Prevent potential memory leaks in reaction handling.The subscription to metisService's createReaction and deleteReaction should be properly managed to prevent memory leaks.
Consider using the following pattern:
+private destroy$ = new Subject<void>(); addOrRemoveReaction(emojiId: string): void { if (this.posting.reactions && existingReactionIdx > -1) { const reactionToDelete = this.posting.reactions[existingReactionIdx]; - this.metisService.deleteReaction(reactionToDelete).subscribe(() => { + this.metisService.deleteReaction(reactionToDelete).pipe( + takeUntil(this.destroy$) + ).subscribe(() => { // ... existing code }); } else { const reactionToCreate = this.buildReaction(emojiId); - this.metisService.createReaction(reactionToCreate).subscribe(() => { + this.metisService.createReaction(reactionToCreate).pipe( + takeUntil(this.destroy$) + ).subscribe(() => { // ... existing code }); } } +ngOnDestroy(): void { + this.destroy$.next(); + this.destroy$.complete(); +}
Line range hint
191-204: Improve type safety in buildReactionMetaDataMap.The method uses non-null assertions (!), which could be replaced with proper null checks for better type safety.
Consider this safer implementation:
buildReactionMetaDataMap(reactions: Reaction[]): ReactionMetaDataMap { return reactions.reduce((metaDataMap: ReactionMetaDataMap, reaction: Reaction) => { const hasReacted = reaction.user?.id === this.metisService.getUser().id; - const reactingUser = hasReacted ? PLACEHOLDER_USER_REACTED : reaction.user?.name!; + const reactingUser = hasReacted ? PLACEHOLDER_USER_REACTED : reaction.user?.name ?? 'Unknown User'; + const emojiId = reaction.emojiId ?? ''; + if (!emojiId) return metaDataMap; const reactionMetaData: ReactionMetaData = { - count: metaDataMap[reaction.emojiId!] ? metaDataMap[reaction.emojiId!].count + 1 : 1, - hasReacted: metaDataMap[reaction.emojiId!] ? metaDataMap[reaction.emojiId!].hasReacted || hasReacted : hasReacted, - reactingUsers: metaDataMap[reaction.emojiId!] ? metaDataMap[reaction.emojiId!].reactingUsers.concat(reactingUser) : [reactingUser], + count: metaDataMap[emojiId]?.count ?? 0 + 1, + hasReacted: metaDataMap[emojiId]?.hasReacted || hasReacted, + reactingUsers: metaDataMap[emojiId]?.reactingUsers.concat(reactingUser) ?? [reactingUser], }; - return { ...metaDataMap, [reaction.emojiId!]: reactionMetaData }; + return { ...metaDataMap, [emojiId]: reactionMetaData }; }, {}); }
Line range hint
37-211: Consider breaking down the directive into smaller, focused components.The directive has multiple responsibilities:
- Reaction management
- Emoji selection
- Bookmark handling
- UI state management
This could make it harder to maintain and test. Consider splitting these responsibilities into separate services or components.
Suggested structure:
ReactionService: Handle reaction CRUD operationsEmojiSelectorComponent: Handle emoji selection UI and logicBookmarkService: Handle bookmark operationsPostingReactionsStateService: Manage UI stateWould you like me to help create a detailed implementation plan for this refactoring?

Line range hint
1-307: Consider breaking down the component for better maintainabilityThe component handles multiple responsibilities including:
- Post management
- Answer post handling
- Dropdown positioning
- Scroll management
- Navigation
- User interactions
Consider:
- Extracting dropdown and scroll management logic into a separate service
- Creating smaller, focused sub-components for specific features
- Moving navigation logic to a dedicated service
This would improve:
- Code maintainability
- Testing capabilities
- Reusability

1-1: LGTM! Import changes align with dependency injection updates.
The addition of inject to the imports is consistent with Angular's modern dependency injection pattern.
27-29: LGTM! Modern dependency injection pattern implemented correctly.
The transition to inject() function follows Angular's recommended patterns and reduces boilerplate code while maintaining proper access levels for inheritance.
src/main/webapp/app/shared/metis/message/message-inline-input/message-inline-input.component.ts (3)
23-23: LGTM: Modern dependency injection pattern
The use of inject() function for LocalStorageService is a good practice in modern Angular, making the code more concise while maintaining proper dependency injection.
8-10: 🛠️ Refactor suggestion
Optimize imports for standalone component
The ArtemisSharedModule import is redundant since the component is now standalone and already imports the specific components it needs (PostingButtonComponent and PostingMarkdownEditorComponent).
Remove the shared module import:
-import { ArtemisSharedModule } from 'app/shared/shared.module';And update the imports array in the @component decorator:
- imports: [ArtemisSharedModule, PostingButtonComponent, PostingMarkdownEditorComponent],
+ imports: [PostingButtonComponent, PostingMarkdownEditorComponent],17-18: 🛠️ Refactor suggestion
Update component encapsulation for better style isolation
The component uses ViewEncapsulation.None which can lead to style leaks. Since it has a dedicated SCSS file, it should use the default encapsulation mode.
Update the component configuration:
@Component({
selector: 'jhi-message-inline-input',
templateUrl: './message-inline-input.component.html',
styleUrls: ['./message-inline-input.component.scss'],
- encapsulation: ViewEncapsulation.None,
standalone: true,
imports: [PostingButtonComponent, PostingMarkdownEditorComponent],
})src/main/webapp/app/shared/metis/message/message-reply-inline-input/message-reply-inline-input.component.ts (2)
17-18: Review ViewEncapsulation.None usage
The component is configured with ViewEncapsulation.None which means styles will leak into other components. Consider if this is intentionally needed or if Emulated encapsulation would be more appropriate.
✅ Verification successful
ViewEncapsulation.None is justified in this case
The use of ViewEncapsulation.None appears to be intentional and necessary here because:
- Both components need to style child elements from the markdown editor (
.markdown-editor-wrapperand.markdown-editor) - The components share identical styling needs for these nested elements
- The styles use
!importantflags to override markdown editor's default styles - Both components are inline input components that need consistent styling across the application
These styling requirements would be difficult to achieve with Emulated encapsulation since it would prevent styling of nested component elements.

The component extends PostingCreateEditDirective but only injects LocalStorageService. Ensure all required dependencies from the parent class are properly handled.
✅ Verification successful
Parent class dependencies are properly handled
The parent class PostingCreateEditDirective uses inject() for its dependencies (MetisService, NgbModal, and FormBuilder), and these services are automatically available to child classes without needing to re-inject them. The LocalStorageService injected in the child component is an additional dependency specific to that component. Everything is correctly implemented.

Add ngOnDestroy lifecycle hook to clean up modal reference
The directive contains a modalRef property but lacks proper cleanup in ngOnDestroy. To prevent potential memory leaks, implement the OnDestroy interface and close the modal in the cleanup hook:
ngOnDestroy(): void {
this.modalRef?.close();
}🔗 Analysis chain
Verify modal service cleanup.
Since the directive injects NgbModal and maintains a modalRef, ensure proper cleanup is implemented to prevent memory leaks.

Add constructor for dependency injection
The component references metisService and formBuilder but lacks proper dependency injection. This could cause runtime errors.
Add the following constructor:
+ constructor(

+ super();
+ }Also, add the missing import:

Migration to standalone components incomplete
The verification reveals that:
- PostingButtonComponent is properly configured as standalone
- PostingMarkdownEditorComponent is not marked as standalone yet
This needs to be addressed as all components used in a standalone component's imports must also be standalone.

💡 Codebase verification
ArtemisSharedModule import can be replaced with specific imports
Based on the template analysis, the component only uses basic Angular directives (ngClass, ngStyle, ngIf) and the jhiTranslate directive. These can be imported directly from their respective modules:
- Replace
ArtemisSharedModulewith:CommonModulefrom@angular/commonforngClass,ngStyle,ngIfTranslateModulefrom@ngx-translate/coreforjhiTranslate
🔗 Analysis chain
Verify the necessity of ArtemisSharedModule import
While the standalone configuration looks good, importing ArtemisSharedModule might go against the standalone component migration objective. Consider extracting only the needed dependencies from this module.

🛠️ Refactor suggestion
Consider implementing proper cleanup for change detection
While the migration to inject() is good, ensure proper cleanup of change detection to prevent memory leaks. Consider using takeUntil with a destruction subject.
Example implementation:
+private readonly destroy$ = new Subject<void>();
ngOnInit(): void {
this.courseId = this.metisService.getCourse().id!;
this.isAtLeastTutorInCourse = this.metisService.metisUserIsAtLeastTutorInCourse();
this.createdAnswerPost = this.createEmptyAnswerPost();
this.groupAnswerPosts();
+ // If you have any subscriptions, use takeUntil
+ // someObservable$.pipe(takeUntil(this.destroy$)).subscribe();
}
ngOnDestroy(): void {
+ this.destroy$.next();
+ this.destroy$.complete();
this.answerPostCreateEditModal?.createEditAnswerPostContainerRef?.clear();
