How do I configure Rollup for my JavaScript library?

To configure Rollup, you'll need to create a rollup.config.js file. Do you have a specific setup in mind?

Yes, I want to bundle my library for both ES modules and CommonJS.

You can achieve that by specifying multiple output formats in your Rollup config. Would you like a sample configuration?

Yes, please provide a sample configuration.

Here's a basic example:

export default {
  input: 'src/index.js',
  output: [
    { file: 'dist/my-library.esm.js', format: 'es' },
    { file: 'dist/my-library.cjs.js', format: 'cjs' }
  ],
  plugins: []
};

This will create both ES and CommonJS bundles.
