Rollup.js 치트시트 (ES 모듈 번들러)

Rollup은 작은 코드 조각들을 효율적인 라이브러리나 복잡한 애플리케이션 번들로 컴파일하는 JavaScript 모듈 번들러입니다.

기본 설정 (rollup.config.mjs)

import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import terser from '@rollup/plugin-terser';

export default {
  input: 'src/index.js',
  output: [
    { file: 'dist/bundle.cjs.js', format: 'cjs' },
    { file: 'dist/bundle.esm.js', format: 'es' },
    { file: 'dist/bundle.min.js', format: 'umd', name: 'MyLibrary', plugins: [terser()] }
  ],
  plugins: [resolve(), commonjs()],
  external: ['react', 'react-dom']
};
