Bun.s3 not being able to be built using target: "node"

[aLemonFox]

What version of Bun is running?

1.2.2+c1708ea6a

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

The Bun s3 client cannot be build on any other target then "bun" (I am assuming no polyfill available as of today?)

// index.ts
import { S3Client } from 'bun';

// build.ts
await Bun.build({
    entrypoints: './index.ts',
    target: 'node',
    outdir: './dist',
});

// output:
import { S3Client } from 'bun';
                             ^
error: Could not resolve: "bun". Maybe you need to "bun install"?

What is the expected behavior?

Build succesfully like using target: "bun"

What do you see instead?

import { S3Client } from 'bun';
                             ^
error: Could not resolve: "bun". Maybe you need to "bun install"?

I'm slightly confused. Are you trying to run your built code with node?

[aLemonFox]

Unfortuantly the serverless runtime we're using does not support Bun but using target:node we could compile to node (everything except for s3 works until now for us). This way we can keep our monorepo in bun which is way easier to manage than a nodejs monorepo :)

If it will not be runned by Bun u should avoid any Bun specific api

Yeah you can "fix" this error by making "bun" external, but you will still need to use the bun runtime as there isn't pollyfills.

This doesn't seem like a bug. Unless @RiskyMH has any objections I think we can close this.
