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.

Ninja Build features and specs

  • Speed
    Ninja is designed for high performance, making it one of the fastest build systems available. It minimizes the time spent on tasks such as parsing, dependency resolution, and build command execution.
  • Simplicity
    Ninja’s configuration syntax is straightforward and concise, reducing the complexity involved in setting up builds and allowing for a clear overview of build rules.
  • Parallelism
    Ninja excels at handling parallel builds, leveraging multiple cores effectively to decrease overall build times.
  • Incremental Builds
    Ninja efficiently handles incremental builds by only recompiling what is necessary, which significantly speeds up iterative development processes.
  • Integration
    Ninja is often used as the backend for more complex build systems (e.g., CMake), making it a versatile tool within a larger toolchain.

Possible disadvantages of Ninja Build

  • Limited Features
    Ninja is deliberately minimalist, lacking many of the features found in other build systems, such as built-in support for complex dependency management and custom build steps.
  • Learning Curve
    While Ninja itself has a simple syntax, the learning curve can be steep for those unfamiliar with how build systems work or for those coming from more feature-rich environments.
  • Dependency on Generators
    Ninja often requires an external generator (like CMake) to create its build files, which can add to the setup complexity and introduce dependencies on other tools.
  • Limited Scripting Capabilities
    Unlike some build systems that offer extensive scripting support (e.g., Python in SCons), Ninja's functionality is largely limited to what its syntax and predefined rules allow.
  • Less Flexibility
    Due to its minimalist nature, Ninja may not be as flexible as other build systems, potentially limiting its use in more complex or unusual build scenarios.

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.

  • Valentine’s Day Breakup: React Dumps Create React App
    Vite is a modern frontend build tool used to develop fast and super efficient web applications. It serves files instantly and ensures that changes are updated immediately after they are implemented. It makes use of Rollup for optimized builds and has support for when you want to build a Javascript library (instead of a full app). - Source: dev.to / about 1 month ago
  • Advanced Guide to Using Vite with React in 2025
    In 2025, mastering Vite for your React projects means leveraging powerful configurations, intelligent optimizations, and a robust plugin ecosystem. By understanding Vite’s modern architecture—native ES modules (ESM) during development and optimized Rollup bundling for production—you can significantly streamline your workflow, improve developer experience, and deliver fast, performant applications at scale. - Source: dev.to / about 2 months ago
  • Optimizing React Development with Vite🤩.
    6. Production-Ready Code Vite uses Rollup for production builds, which optimizes the code by bundling it efficiently, performing tree shaking, and minifying JavaScript. This results in smaller, optimized production builds that are ready for deployment. - Source: dev.to / 5 months ago
  • What is Evan You doing by creating VoidZero, and what are the issues with JS toolchains?
    Meanwhile, esbulid (developed in Go language, as introduced earlier) and rollup can also be used separately as packaging tools, and many third-party JS plugins are packaged using rollup. - Source: dev.to / 5 months ago
  • Node.js: A brief history of cjs, bundlers, and esm
    Npm packages dramatically sped up the productivity of developers by being able to leverage other developers' work. However, it had a major disadvantage: cjs was not compatible with web browsers. To solve this problem, the concept of bundlers was born. Browserify was the first bundler which essentially worked by traversing an entry point and "bundling" all the require()-ed code into a single .js file compatible... - Source: dev.to / 5 months ago
