I am not sure if this is a typebot issue, but I open this issue to document this and give a workaround.

For some reason I wasn't able to pinpoint, I started hitting and issue where pnpm dev would crash with:

[!] (plugin typescript) RollupError: @rollup/plugin-typescript TS2354: This syntax requires an imported helper but module 'tslib' cannot be found.

I searched a bit and I was unable to find a definitive explanation to this issue.

But in case you encounter it, my fix was to change importHelper to false in the following file:

typebot.io/packages/lib/tsconfig.json

Line 7 in 37ef8fe

"importHelpers": true

change to:

    "importHelpers": false

Good to know, thanks, I don't remember why this was enabled though, I just removed it and it built without error so I'll push this

I don't know what changed, but now when there is an error in my code, the whole pnpm dev process dies, but before it would just print the error and let me correct it before recompiling.

I can reproduce this 100%.

I found a few references:

Can't reproduce, but I may be stumble upon this issue once and added importHelpers for that reason.

Can you try to delete node_modules folders and dist folders and install and build again?

I did a git clean to remove everything and I also removed ~/.local/share/pnpm and ~/.cache/pnpm

but the issue persists.

This is not the same error, it's an issue with your code here

Yes, but that's the whole point. When there is an error in my code, reporting this error crashes rollup and pnpm dev.

When developing forge plugin, the app automatically reloads when the code change, but now when there is a typo in the code, the whole pnpm dev process crash.

Got it. that comes from "noEmitOnError": true. I added it recently because we could basically build the app with an error.

I'll see if I can disable this when running dev

Ok I was able to fix the tslib issue.

    "tslib": "2.6.0"

Must be added to the package.json of the forge package (as a dependency, not dev dependency as tslib is a runtime library) and "importHelpers": true must be added to the tsconfig.json of the forge package.

Now that this is fixed, changing noEmitOnError does fix the pnpm dev process crashing.

So it is actually two separate issues that got mixed. One issue is that noEmitOnError changed, and this made me realize the other issue which is that tslib is a runtime dependency and should be added to the dependencies of the packages requiring it and NOT devDependency (first line of the README https://github.com/Microsoft/tslib).

kuon commented Aug 22, 2024

So the fix for the tslib issue is to modify the create-new-block script to add:

"importHelpers": true

below this line

typebot.io/packages/forge/cli/index.ts

Line 197 in 503060c

jsxImportSource: 'react',

and

dependencies: { "tslib": "2.6.0"}

below this one:

typebot.io/packages/forge/cli/index.ts

Line 171 in 503060c

license: 'AGPL-3.0-or-later',

I guess the rest of the uses of tslib in the rest of typebot should also move it to dependencies but honestly I am not sure. I don't use typescript on a daily basic and this is all new to me.

Ok I did more tests, and I can no longer reproduce it 100%. It does happens sometimes but not always. It seems to depend on the order which viewer:dev, nextjs:dev and react:dev appears in the logs, but I am not sure as the logs are widely different when it occurs vs when it does not occur.

But I can confirm that my proposed fix is not actually a fix, it just happened to work at the right time. And I guess that's why I thought the first fix was also a fix. I guess I was unlucky because I tried about 10 times and it seemed to work, but now, with more load on my dev server with other tasks, it is happening a lot less.

I suggest we close this and keep it for reference if it happens again. I am sorry for taking so much of your time with this.
