Any ETA on this one?

[vjpr]

I would guess this is a big blocker for a lot of people. All my Node.js packages are using #imports so I can't try out Bun yet.

[Jarred-Sumner]

This is implemented and will soon be available in the canary build of bun:

bun upgrade --canary

@Jarred-Sumner Tried this on the latest (0.2.1) and it seems the issue is still there.

Any kind of flag needed, perhaps?

[vjpr]

@Jarred-Sumner Doesn't seem to work in 0.2.2.

I couldn't get any #src/index.js imports to work.

error: Could not resolve: "#src/index.js". Maybe you need to "bun install"?

import index from '#src/index.js'

  "imports": {
    "#src/*": {
      "types": "./src/*.js",
      "transpile": "./src/*",
      "node": "./lib/*",
      "bun": "./src/*.js"
    }
  },

{
  "extends": "./node_modules/@live/scripts/tsconfig/tsconfig.json",
  "compilerOptions": {
    "rootDir": ".",
    "baseUrl": "src",
    "jsx": "react"
  }
}

But I also use wildcards which I found isn't supported yet #1402 <- probably good to wait for this one.

Also found this ticket #1337, that indicated bun subpath which is why I tried it above. Couldn't find docs on this.

Canary just upgraded to 0.2.3 now...the command didn't upgrade earlier...rechecking.

EDIT: Everything I try doesn't seem to work still...

I confirm that this is still an issue.

For example

import test from '#utils/test';

Will not work.

I guess that this has to do with extension resolution - e.g. test.js might work.
