esbuild doesn't remove unused imports from external modules

[egoist]

Tested against:

export { useRoute } from "vue-router"

The command I ran:

esbuild index.js --bundle --outfile=out.js --external:vue --format=esm

Result, unused imports from vue:

same problem here...

// helper.js
import scrollIntoView from "scroll-into-view";

export async function centerScroll(){
return scrollIntoView(/* ... */)
}

export async function delay(){
// ...
}

import {delay} from "./helper.js"
/* this causes scrollIntoView to also be in the bundle!  */

i wish this could be fixed, esbuild is literally perfect.... except this problem, one of the reasons to use a bundler is because of the tree shaking

Any updates on this? Maybe a plugin could help?

Darn I'm seeing this as well...

Thought I was going mad. Also seeing this when using named imports
