Webcontainer API: Won't start node.js server

[archiewood]

Describe the bug

Excitedly trying out the web containers API 🎉

I have a project that works in vanilla stackblitz and I’m trying to create a webcontainer API version of it using the new tutorial.

It installs the deps fine, and then chokes on “npm run dev” somehow - it just gets stuck on "installing deps"

Link to the blitz that caused the error

https://stackblitz.com/edit/vitejs-vite-x3wklg?file=main.js

Steps to reproduce

Go to Stakblitz Link and wait for the webcontainer to boot

Expected behavior

I expected the node app to boot in the RHS of the window

Parity with Local

• I have run the project in my local machine and I could not reproduce the issue.

Hi @archiewood 👋 . Thanks for reaching out. I tested your project and indeed, it does not work. I also logged the output of npm run dev to the console to see what's going on.

So it seems that evidence tries to install svelte-kit, and then tries to run the svelte-kit binary but it can't seem to find it. So I tried to run it in a separate project, but I get the same error.

Can you maybe share your working StackBlitz project? That might help identify the issue, but it might be config related?

One small tip (in case we get this working). If you also load the package-lock.json that corresponds to the package.json you load into the WebContainer API, the npm install times will be much faster.
