Walkthrough

This update enhances TypeScript compatibility in module imports by adjusting the importModule function in src/import.ts. Along with this, new test cases in test/import.test.ts ensure coverage for various import scenarios. Additionally, new TypeScript fixture files (exports.ts, index.ts, mod.ts) add examples of default and named exports, providing comprehensive test coverage and ensuring correct behavior during imports.

Changes

Files & Directories	Change Summaries
src/import.ts	Modified importModule function to enhance TypeScript compatibility. Adjusted conditional checks and added code for handling TypeScript modules.
test/fixtures/ts-module/exports.ts	Introduced two exported constants: foo with the value 'bar' and one with the value 1.
test/fixtures/ts-module/index.ts	Exported an object with property foo: 'bar' and a constant one with value 1.
test/fixtures/ts-module/mod.ts	Introduced a default exported function returning an object { a: 1 }.
test/import.test.ts	Added tests to cover importing modules in TypeScript, including default imports, named exports, and module-level exports.

Poem

In the world of code so bright,
Modules dance from day to night,
Import tweaks in types make cheer,
As tests ensure no flaws appear.
Constants and defaults play a part,
In TypeScript harmony, a work of art.
A rabbit hops through fields of code,
Enhancing imports as it rode. 🌟🐇

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

src/import.ts (1)

Line range hint 58-83: The modified conditional logic in importModule enhances TypeScript module compatibility. However, there's an unsafe usage of optional chaining.

- if (obj?.default?.__esModule === true && 'default' in obj?.default) {
+ if (obj?.default && obj.default.__esModule === true && 'default' in obj.default) {

This change ensures that the evaluation does not throw a TypeError if obj.default is undefined.
