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.

Rollup v. Webpack v. Parcel
Rollup provides much simpler configuration over webpack 4 and has a host of pre-configured plugins that are a breeze to incorporate into your project. Rollup's also the fastest of the build tools period.

  • Dead Code kills silently
    This article presents a bunch of ways how to find unused code, remove it, and configure tools and bundler to prevent dead code in the future. Sections for bundler are based on set of Vite, which under the hood delegates to Rollup in production. - Source: dev.to / 2 months ago
  • Claude Code's Source Didn't Leak. It Was Already Public for Years.
    The reality is simple: minification was never security. It's a size optimization that bundlers like esbuild, Webpack, and Rollup do by default. Variable renaming slows down human readers but LLMs read minified code like you read formatted code. - Source: dev.to / 5 months ago
  • Workspaces, react and vite. A real-world case study for managing duplicate libraries.
    Before addressing the solution, it's useful to contextualize the role of the bundler. In a modern frontend architecture, the bundler (such as webpack, rollup, or vite) has the task of traversing the application's dependency graph, resolving each import statement, to combine modules and assets into static files optimized for browser execution. - Source: dev.to / 9 months ago
  • One Package, Two Formats: Publishing npm Libraries with Nx
    As a library author, it’s important to support both legacy CommonJS projects and modern ESM projects. The solution is to publish a single npm package compatible with both module formats. This guide demonstrates how to build and publish a universal NPM package using the Nx Dev Toolkit and Rollup. - Source: dev.to / 11 months ago
  • Everything about ESM and treeshaking
    I did try rollup with terser but I saw similar results. - Source: dev.to / about 1 year ago
