SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rollup bundling guidelines help library authors produce lean, portable bundles using Rollup.js, enabling maintainable configurations and predictable output.

Core Features & Use Cases

  • Guidance for common Rollup configurations (input, outputs, plugins) to generate esm, cjs, and umd builds
  • Best practices for tree-shaking, external dependencies, code-splitting, and source maps in library projects
  • Use cases including library development, multi-format distribution, and automation of build workflows

Quick Start

Configure Rollup with a config file and run rollup -c to generate optimized bundles

FAQPage Schema
How do I configure Rollup to output multiple formats like ESM and CommonJS?

You can configure Rollup to output multiple formats by defining separate output targets in your configuration file. This generates ESM, CommonJS, and UMD bundles simultaneously from a single entry point.

What is the best way to enable tree-shaking for a JavaScript library?

The best way to enable tree-shaking is using Rollup.js, which automatically eliminates dead code when bundling ES modules. Configure your library to use ESM imports and exports to ensure optimal bundle size reduction.

How do I manage external dependencies when bundling a library with Rollup?

Managing external dependencies with Rollup requires specifying the external option in your configuration. This prevents peer dependencies and utility libraries from being bundled into your final package output.

Can I use Rollup with TypeScript and Babel for library development?

Yes, Rollup supports TypeScript and Babel integration through specific plugins. You can transpile modern JavaScript and apply type stripping while generating lean, production-ready bundles for library distribution.

Does Rollup support code splitting and source maps for ES modules?

Rollup supports both code splitting and source maps for ES modules. These features manage dynamic imports and simplify debugging by mapping compiled bundle code back to original source files.

Why should I use Rollup over other bundlers for a JavaScript library?

Rollup excels at bundling JavaScript libraries because its ES module architecture produces leaner output with superior tree-shaking. It generates portable, production-ready packages without the runtime overhead typical in application bundlers.
