| description.long | A fast bundler that combines JavaScript and other web assets into optimized output, with built-in TypeScript support and APIs accessible through command-line, JavaScript, and Go interfaces. | Rollup is a module bundler that compiles JavaScript code written as ES modules into various output formats for compatibility with different environments. It performs static analysis to eliminate unused code and can target modern browsers with native ES module support or legacy environments requiring CommonJS or UMD output. |
