Bug: PassThrough is not exported by "__vite-browser-external" during build

[ii02735]

Summary

In a project, I use the following dependency : https://www.npmjs.com/package/minify-xml

Because it is a dependency written for a pure NodeJS project, I had to use polyfills like this :

import { defineConfig } from "vite";
import { nodePolyfills } from "vite-plugin-node-polyfills";

export default defineConfig({
    plugins: [nodePolyfills({
        include: ['_stream_passthrough', 'util']
    })]
})

What I expect

Everything should work in dev mode, or when I build the project.

What I got

• In dev mode, everything is working ✅
• When I try to build the project, it fails 💥

I have the following error :

My setup

• Vite v5.
• Windows 11
• NodeJS v20.9.0

Passthrough is imported from stream. So have you tried importing stream instead of _stream_passthrough?

Also try setting protocolImports: true, since it is importing Passthrough from node: protocol import.

I encountered the same issue and this fixed it for me.
