Describe the Bug

Astro is unable to use the bun:sqlite package.
Error:

george@Georges-MacBook-Pro words % bun run dev
$ astro dev
  🚀  astro  v3.0.12 started in 97ms
  
  ┃ Local    http://localhost:4321/
  ┃ Network  use --host to expose
  
Error: The following dependencies are imported but could not be resolved:

  bun:sqlite (imported by /Users/george/Desktop/code/cabbage/words/src/util/db.ts)

Are they installed?
    at file:///Users/george/Desktop/code/cabbage/words/node_modules/vite/dist/node/chunks/dep-df561101.js:45705:23

    at async file:///Users/george/Desktop/code/cabbage/words/node_modules/vite/dist/node/chunks/dep-df561101.js:45114:38
^C

What's the expected result?

The bun:sqlite can be imported and used.

Astro is a Node framework. If something specific to another runtime doesn't work, not only I don't know what we could do about it, but also, it's unrelated to us. I'd recommend raising the issue over to the people at Bun.

[Jarred-Sumner]

I hate saying this but

This appears to be a bug in Astro.

Astro's module resolution prevents bun builtin modules from being used. Astro resolves modules before Bun's module resolution runs. Bun cannot fix this without overriding Astro's module resolution altogether, which would break Astro on Bun in other ways and is generally not something you want.

You can fix this by marking bun:* as external, probably similarly to what happens with node:*

I would assume that this affect every Vite SSR app then, doesn't it?

I just tried @Jarred-Sumner's suggestion, without luck. And yes @Princesseuh, I would assume this affects any Vite SSR app.

I couldn't even get the dev-server running without adding "bun:sqlite" to the vite.optimizeDeps.exclude configuration option. Nothing seems to help with accessing the bun:sqlite in SSR though. I've tried "external", disabling "optimizeDeps", etc.

I kept getting this:

 error   Cannot find module 'bun:sqlite' imported from '/home/andri/git/event-puffin-astro/src/lib/db/index.ts'

In Vite's ssrModuleLoader.ts there's an escape hatch for node: and data:. I'd assume we'd need Bun added there, for this to work.

async function nodeImport(
  id: string,
  importer: string,
  resolveOptions: InternalResolveOptionsWithOverrideConditions,
) {
  let url: string
/* WE NEED TO ADD BUN HERE */
  if (id.startsWith('node:') || id.startsWith('data:') || isBuiltin(id)) {
    url = id
  } else {
    // Internal Vite resolution stuff. Uses node-resolve Rollup plugin.
}

In other words, this needs to be fixed in Vite, not Astro. I'd love to raise the issue, but I'm not familiar with the SSR API in Vite in order to reproduce it there.

It appears the Vite use case is handled by Bun.

By adding --bun: The --bun flag tells Bun to run Vite's CLI using bun instead of node.

bun --bun run astro build

Feel free to open an issue in Vite regarding this. I think that line should indeed fix it, but Vite probably needs a more standardized flow internally for handling different runtime builtin protocols.
