node_modules folder created in my build folder

Hi @Anidetrix , After adding this plugin 2 files created in bellow path, Have you any idea about this? How I can prevent this?

build/node_modules/rollup-plugin-styles/dist/runtime/inject-css.js
build/node_modules/rollup-plugin-styles/dist/runtime/inject-css.js.map

You can solve it using 2 plugins 😃

import replace from '@rollup/plugin-replace';
import rename from 'rollup-plugin-rename';

export default {
  // your configuration
  plugins: [
    // your other plugins
    rename({
      include: ['**/*.js', '**/*.mjs'],
      map: (name) => name.replace('node_modules/', 'external/'),
    }),
    replace({
      values: {
        'node_modules/': 'external/'
      },
      delimiters: ['', '']
    })
  ],
}

I’m afraid nothing can be done with this at the moment due to how Rollup’s preserveModules option works.

It’s explained in this comment:

The folder is created because preserveModules is preserving the original file names and directory structure. It does not understand that node_modules is something special, though. Also, all exports are rewritten in a way that does not depend on Node’s dependency resolution algorithm.
