Describe the bug

I get the error RollupError: Could not resolve entry module "Popup.html". when building a nested project from a root package.json

If I change manifest to (erroneously) include the nested dir name , e.g.

{
  "manifest_version": 3,
  "name": "My React Chrome Extension",
  "version": "1.0.0",
  "description": "A Chrome extension built with React and TypeScript.",
  "permissions": ["storage", "tabs"],
  "action": {
    "default_popup": "extension/Popup.html"
  }
}

I can get the build to work, but then the extension doesn't work in chrome (unsuprising, it shouldnt have the dir name in there) .

I shouldn't need the nested dir name there because that dir is the root of the vite.config.js via root: __dirname configuration, which works for everything else. It just doesn't seem to work for crx. I tried to find a parameter to tell crx to use that as the root explicity but I can't find one. Is there a simple configuration parameter I am missing?

Reproduction

create a directory nested inside of an existing web probject, e.g. {project_root}/extension with extension/vite.config.ts as such:

import { resolve } from 'path';

import { crx } from '@crxjs/vite-plugin';
import react from '@vitejs/plugin-react';
import { defineConfig } from 'vite';

import manifest from './public/manifest.json';

export default defineConfig({
  plugins: [react(), crx({ manifest })],
  root: __dirname, // Use the extension directory as root
  build: {
    outDir: '../dist-extension', // Output directory for the extension
    sourcemap: true,
    emptyOutDir: true,
  },
});

in root package.json, add script:

"build:extension": "vite build --config extension/vite.config.ts"

run pnpm run build:extension

Error:

RollupError: Could not resolve entry module "Popup.html".

Out of curiosity what setup is this lerna or something with extension as one of the packages?

Its just a normal (complicated) react app originally created from CRA and ported to vite. extension is just the subdirectory I put the chrome extension code/subproject in.
