Features & Specs

  1. Tree Shaking

    Rollup.js performs treeshaking to eliminate dead code, resulting in smaller bundle sizes. It analyzes the dependency tree and includes only the parts of the code that are actually used.

  2. Output Formats

    Supports multiple output formats including ES modules, CommonJS, AMD, UMD, and IIFE. This makes it versatile for different use cases.

  3. Plugins

    Rollup.js has a rich ecosystem of plugins that extend its functionality, such as code transformation, minification, and support for various types of modules.

  4. Code Splitting

    Supports code splitting, allowing you to break your code into smaller chunks that can be loaded on demand. This improves performance for larger projects.

  5. Efficient Bundling

    Offers efficient bundling by removing duplicates and ensuring that each module gets included only once, which contributes to reduced bundle size.

  6. Minimal Configuration

    Generally requires minimal configuration to get started, focusing on simplicity and ease of use.
