rollup.js features and specs

  • 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.
  • Output Formats
    Supports multiple output formats including ES modules, CommonJS, AMD, UMD, and IIFE. This makes it versatile for different use cases.
  • 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.
  • 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.
  • Efficient Bundling
    Offers efficient bundling by removing duplicates and ensuring that each module gets included only once, which contributes to reduced bundle size.
  • Minimal Configuration
    Generally requires minimal configuration to get started, focusing on simplicity and ease of use.

Possible disadvantages of rollup.js

  • Learning Curve
    Although relatively simple to use, there is still a learning curve associated with understanding its configuration and the plugin system.
  • Initial Build Time
    The initial build time can be slower compared to some other bundlers, particularly for larger projects.
  • Limited Built-in Features
    Rollup.js focuses on being a minimalist tool, so it lacks some of the built-in features that other bundlers may have. Often, additional functionality needs to be added via plugins.
  • Plugin Compatibility
    Not all plugins work seamlessly with Rollup.js, and there may be occasional compatibility issues, especially with plugins originally designed for other bundlers.
  • Node.js Ecosystem
    While Rollup.js excels in bundling for browsers, it is not as commonly used for Node.js applications compared to other tools like Webpack.
  • Community Size
    The community size is smaller compared to other bundling tools like Webpack, which can sometimes make finding solutions to issues more challenging.
