Error when using this inside of a npm workspaces monorepo

[adoublef]

Seems to fail when used in a npm workspace.

details of the error as it is expecting the package the projects node_module directory which is not possible with the workspace

located in the root node_module directory of the workspace/monorepo

This is a Svelte not a SvelteKit project but unsure that would make a difference.

Module does exist here

sorry, I have no idea what should I do with this.

[adoublef]

when using the second param, it looks into the node_module folder to locate the package. the first screenshot shows that attempt.

however if I have structured my whole directory as a npm workspace then there is two node_module folders; that projects one (which generally doesn't have much) & the global one (to share between different projects in that monorepo).

the issue is that the second param does not account for this & that is why it is assuming the directory does not exist.

however it does exisit (which is what the second screenshot on the leftside was supposed to show).

I am not sure how this could possibly be fixed.

I believe the examples that have been shown/tested have been solo projects not monorepos hence why this fault is showing up for me now.

in my example the expected path should be /workspace/examples/node_modules/@topheruk/hello-world/hello_world_bg.js

but I am seeing it say /workspace/examples/<path_to_sub_package>/node_modules/@topheruk/hello-world/hello_world_bg.js

The issue seems to lie with how you are creating the path inside the prepareBuild function.

I am trying to figure out where path_1.default is coming from as this is what I believe needs to change inorder for this to work

Inspecting this more and its the use of path.join path.resolve() on line 121, that I think is where you would want to check the top-level node_module directory in the current workspace somehow

Hi, @topheruk could you try v0.1.12.

[adoublef]

EDIT: It works, needed to add main field into my module's package.json as the module was not working (wasm-pack built my module without the main and will need to look into why that was the case)

Still an error

Do you have an example of a wasm module built with rust that I could try?

My wasm module, located [here[(https://www.npmjs.com/package/@topheruk/hello-world) & although it is listed on the npm registry & I can load it in a Svelte app (by copying the wasm file into public folder and calling it inside the init function, with this plugin its not working.

I have a PR (#16) going up for to fix a bundling issue I have (may not affect y'all) but here is an example of me using it in a monorepo with pnpm workspaces https://github.com/greym0uth/sorrakis

[nshen]

hi @greym0uth, based on @topheruk 's report, seems require.resolve can only resolve main, not module ?

and sorry #16 changed too much, I don't have time to try this recently, I think I should revert it for now. I'll continue when I got time.

Is there a simple way to fix this? @topheruk , I never tried monorepo, but shouldn't the submodule have a link to global? I hope you can figure it out and do a pr. I 'm too busy with my work, and long time no touch rust :(

[adoublef]

I will look into this resolving for modules for my needs its not super inconvenient to add the main key to the auto-generated package.json file.

would be worth just highlighting in the README for those using wasm-pack (unsure if Go/C/C#/etc. would have the same issue with their respective bundlers) that this step will need to be required in order for this too work.

wasm-pack does compile to commonJS that used the main key by default but that is mainly for nodejs applications not really the web apparently.

I can give @greym0uth the PR a go though I must preface this by saying I am new to issues & PRs on Github, so would need assistance on that front

Hey I'm running into pretty much the same issue, @topheruk any updates? You mentioned adding the main key but that just throws me:
<package> doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module?

Did you not run into that when you removed the module property and added main?

[adoublef]

This week I'm going to have a deeper look at this issue as there is likely a few cases which need to be looked into. I didn't get that error but then there may have been a recent update to vite that introduced this so can't guarantee my fix still stands.

@DoctorBracewell are you using pnpm, npm or yarn? i am unsure if that should make a difference but worth sharing. also which version are you currently using?

This also my first attempt at dealing with a node project of this sort so not an expert at all.

[DoctorBracewell]

Currently using npm right now. I'll take a look at it was well if I have the chance, please keep us updated if you find anything :)

[DoctorBracewell]

I've made a comment on an issue in the wasm-pack repo and will probably look into a pull request for wasm-pack to add the main field to its output - not 100% sure if that PR might have any unintended side-effects.
