Rollup VS webpack

Compare Rollup vs webpack and see what are their differences.


Next-generation ES module bundler (by rollup)


A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff. (by webpack)

  • Rolldown
    2 projects | | 8 Mar 2024
    Doesn't Rollup already use quite a bit of rust[0]? It's actually why I had to abandon it for a project, where they didn't offer binaries for our build platform and I needed to bundle, like 2 ES6 javascript libraries so I just grabbed esbuild instead.


  • Build a Vite 5 backend integration with Flask
    11 projects | | 25 Feb 2024
    Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

  • How to build and publish React TypeScript NPM packages with Vite
    4 projects | | 4 Jun 2023
    Vite (read as vit) is actually a combination of two great frontend tools - an immensely fast development server and a build command for shipping heavily optimized static assets using Rollup. Many developers have encountered the process of setting up a project using Create React App. While CRA can be useful for beginners due to its simplicity and abstraction of configuration, it has some drawbacks that outweigh its benefits, particularly its tendency to be bloated. Don't get me wrong, Vite is opinionated as well, but it's highly extensible through its Plugin API.
  • Building a modern gRPC-powered microservice using Node.js, Typescript, and Connect

    As we iterate on the definition, we are going to want a better developer experience for rebuilding the package on changes. Typically, for a “library” or “utility” style package, I’d reach for either unbuild’s stub concept or use esbuild/tsup/rollup to implement a more traditional watch/rebuild, but in this case, I’m watching a proto file that lives outsides of the source, which breaks assumptions of those tools.
  • Buildless workflow through import maps (featuring Lit, Shoelace and more)
    2 projects | | 12 Apr 2023
    As we can see, we have two external dependencies and one internal tool. In the modern way of packaging our application, we would be of course required to package this project using some bundler like ESBuild or Rollup. But with import maps, we can instead utilize CDN's to deliver our packages and completely eliminate the bundling step.

  • Optimizing React Apps for Performance: A Comprehensive Guide
    2 projects | | 2 Apr 2024
    Click "Start Test." WebPageTest generates a comprehensive report with details about the loading process, including time to first byte (TTFB), page load time, and visual progress. ### Setting Benchmarks with Lighthouse Start with Lighthouse audits to maximize the performance of your React application. Evaluate Lighthouse's scores and suggestions with careful consideration. Next, set benchmarks that are in line with industry norms or customized to meet your unique performance goals. Lastly, pay close attention to the places in your application where it needs work. You can improve your React application's effectiveness by carefully following these procedures, which will guarantee that it satisfies the required performance requirements. ### Analyzing Performance Results with WebPageTest In order to fully evaluate your webpage's performance, launch WebPageTest with a variety of systems, simulating a variety of user scenarios. Examine the waterfall chart carefully to identify loading patterns and bottlenecks, which are essential for improving the user experience. To see the page's rendering process over time and do a thorough examination, use filmstrip views. To effectively assess performance, pay special attention to measures such as time to first byte (TTFB), start render time, and fully loaded time. Also, a better understanding of performance variances is made possible by comparing findings across various test designs, which helps make well-informed recommendations for improving webpage responsiveness and efficiency. ## Impact of third-party libraries on React app performance Third-party library integration can speed up development while improving functionality in our React application. It's crucial to consider the possible effects on performance, though. Because heavy or poorly optimized libraries might negatively impact the speed and usability of our application. ### Bundle Size Look at the distribution file sizes related to the library, and use tools such as Bundlephobia or Webpack Bundle Analyzer to fully evaluate their impact on your bundle size. This thorough analysis enables you to make well-informed decisions about whether to include the library, making sure that its contribution minimizes superfluous bulk in your application's codebase and is in line with your optimization goals. ### Network Requests Analyze how the third-party library affects network requests to maximize performance. Reduce the number of requests made overall by minimizing external dependencies. This will enhance the user experience and loading speeds. Select appropriate libraries, maximize asset delivery, and leverage code splitting to load components asynchronously. You may improve the effectiveness and responsiveness of your application and provide users with a better experience by cutting down on pointless network queries. ### Execution Time Examine the library's code for any possible performance problems or bottlenecks in order to analyze the runtime performance of the library. Look for places where the code may execute slowly or inefficiently. You may ensure smoother operation inside your application by identifying and addressing any areas of the library's implementation that may be impeding ideal performance by doing a comprehensive assessment. ### Code Splitting for Third-Party Libraries Implementing code splitting is an effective strategy to load third-party libraries only when they are required, reducing the initial page load time. Use dynamic imports to load the library lazily:

    Thanks for the thorough answer!

    I confess I wasn't thinking about a particular build tool. My recent experience has been with Vite, where I took a similar approach to what you describe, but haven't had to dig deep into bundle performance because that's not a bottleneck for our application. The last time I did deeper work on the subject was years ago with Webpack.

    I thought Webpack at least did dead-code elimination before splitting things into chunks. If I'm reading this random GitHub issue[1] right (and the asker is also right), Webpack does partially behave as I expected, but the pre-chunking optimization pass occurs before things like constant expression evaluation.

  • How to improve page load speed and response times: A comprehensive guide
    8 projects | | 26 Feb 2024
    Many web pages use CSS and JavaScript files to handle various features and styles. Each file, however, requires a separate HTTP request, which can slow down page loading. Concatenation comes into play here. It involves combining multiple CSS or JavaScript files into a single file. As a result, pages load faster, reducing the time spent requesting individual files. Gulp, Grunt, and Webpack are some of the tools that can assist you in speeding up the concatenation process. They enable seamless merging of many files during development, ensuring deployment readiness.
  • Build a Vite 5 backend integration with Flask
    11 projects | | 25 Feb 2024
    Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.
