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.
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 2 months ago
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
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
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
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
Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. Rollup Documentation. - Source: dev.to / 6 months ago
The JS SDK now lets you opt out of specific modules you don't need and optimize the final bundle size. You can do that by using either of two popular JavaScript build tools: Rollup or Webpack. - Source: dev.to / 6 months ago
Rollup.js is a JavaScript module bundler that compiles small pieces of code into larger, more complex applications. It is particularly well-suited for bundling ES6 modules and is known for its efficient tree-shaking capabilities, which eliminate unused code from the final bundle, resulting in smaller file sizes. - Source: dev.to / 7 months ago
This is also a valid approach, but what we really want is to be able to write our code in TypeScript and have it transpile into the JavaScript we need. Enter Rollup. - Source: dev.to / 9 months ago
If you're working with a modern web framework like React or Vue, you might be using something like Webpack or Rollup to bundle your assets. These tools are great, but a simpler approach to managing assets exists. This is where DAM can complement your existing build process. - Source: dev.to / 9 months ago
Since my widgets required a high level of reactivity, I relied heavily on the Svelte component API and used Rollup for bundling. "It was simple and direct until I got the following problems:. - Source: dev.to / 9 months ago
My bundler of choice is Rollup.js. It's the thing that powers Vite and I think it's great. So in my repo you'll find the following rollup.config.mjs file in the app root here. - Source: dev.to / 9 months ago
Rollup is a module bundler for JavaScript that focuses on ES modules and is particularly good for library development. - Source: dev.to / 10 months ago
Vite is not a bundler but a frontend tool that intelligently uses ESBuild and Rollup for their best use cases. - Source: dev.to / 11 months ago
A big part of my work revolves around JavaScript tooling, and as such it's important to keep an eye on the ecosystem and see where things are going. It's no secret that recently lots of projects are native-ying (??) parts of their codebase, or even rewriting them to native languages altogether. Esbuild is one of the first popular and successful examples of this, which was written in Go. Other examples are Rspack... - Source: dev.to / 12 months ago
If we don't want to use Vite or SvelteKit, or if we don't have the means to use them, then we need to integrate Svelte with our own environment. In our daily development, we usually use webpack or Rollup as our project's module management packaging tool. Therefore, I will introduce these two environments, how to build the Svelte environment. - Source: dev.to / 12 months ago
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... - Source: dev.to / about 1 year ago
Besides Webpack, there are many other popular web bundlers available, such as Parcel, Esbuild, Rollup, and more. They all have their own unique features and strengths, and you should make your decision based on the needs and requirements of your specific project. Please refer to their official websites for details. - Source: dev.to / over 1 year ago
In the Node.js ecosystem, bundling is typically handled by third-party tools rather than Node.js itself. Some of the most popular bundlers in the Node.js world include Webpack, Rollup, and Parcel, offering features like code splitting, tree shaking, and hot module replacement. - Source: dev.to / over 1 year ago
Rollup is another popular JavaScript module bundler focusing on high performance. It excels at tree-shaking and uses ES module syntax to generate more performant bundles than traditional module bundlers. In addition to JavaScript, Rollup supports bundling CSS and JSON as well. Rollup has more than 12 million weekly NPM downloads. - Source: dev.to / almost 2 years ago
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... - Source: dev.to / almost 2 years ago
