Infinite loop using @rollup/plugin-url

[bastienrobert]

I'm getting an infinite loop when I'm using @rollup/plugin-url with Nollup (but not with Rollup).

• @rollup/plugin-url 5.0.1
• nollup 0.12.0
• rollup 2.19.0

Here's a demo repository : nollup-url-infinite-loop

I tried too to downgrade but it's the same 😕

Thanks for the repro! Infinite loop like that usually indicates that a plugin is writing to the disk, which causes the file watcher to trigger a rebuild. That seems to be the issue with @rollup/plugin-url, it's writing to disk using fs.

Ideally the plugin should be updated to the use the proper emitFile API, or change the plugin hook to writeBundle instead which makes more sense anyways than generateBundle.

As a temporary workaround, you can use the watch.exclude option to exclude the dist directory.

export default {
  input: `${src}/index.js`,
  output: {
    dir: dest,
    format: 'iife',
    entryFileNames: '[name].[hash].js',
    assetFileNames: '[name].[hash][extname]',
  },
  plugins: [url()],
  watch: {
    exclude: ['dist', 'node_modules', '.git']
  }
}

Woops, closing this too fast. I tried to exclude these folders as you specified. Repro has been updated but I still have the same issue :(

Hmmm, it works for me. Can't reproduce.

the suggested solution above didn't work for me, but passing in watch: 'src' as a nollup option (rather than in the rollup config) worked a treat.
