Feature Request: Configure The Build Command

[johngeorgewright]

It would be very helpful if the build command also read the bunfig.toml file. This way we could use the same preloaders, configured in our bunfig, without having to write another script.

preload = ["./plugins.ts"]

# If this were to read the bunfig above, then it would include the preloaders.
bun build --watch --entrypoints ./foo.ts --outdir dist

Currently I need to write a script to do this and that reuses the plugins, before they're added with the plugin() function:

// ./build.ts
import { plugin1 } from './plugin1'

Bun.build({
  entrypoints: ['./foo.ts'],
  plugins: [plugin1]
})

bun ./build.ts

What's worse is that if I use the --watch flag on the command above, it only watches the build.ts and not the entrypoints. So then I need to write my own watcher too 😢

// ./build.ts
import { watch } from 'fs'
import { plugin1 } from './plugin1'

watch(path.join(import.meta.dir, '/src'), { recursive: true }, build)
build()

function build() {
  Bun.build({
    entrypoints: ['./foo.ts'],
    plugins: [plugin1]
  })
}
