Rollup vs Webpack: JavaScript Module Bundlers Comparison

Both Rollup and Webpack are popular tools that combine your JavaScript code and its dependencies into a single bundle for production. Rollup specializes in creating smaller, more efficient bundles for libraries and is known for 'tree-shaking' (removing unused code). Webpack is more feature-rich and better suited for complete applications, offering extensive plugin support and handling various asset types beyond JavaScript.

Overview

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. It uses the standardized ES module format for code, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. Rollup can optimize ES modules for faster native loading in modern browsers, or output a legacy module format allowing ES module workflows today.

Quick Start Guide

Install with npm install --global rollup. Rollup can be used either through a command line interface with an optional configuration file or else through its JavaScript API. Run rollup --help to see the available options and parameters. The starter project templates, rollup-starter-lib and rollup-starter-app, demonstrate common configuration options, and more detailed instructions are available throughout the user guide.

Commands

These commands assume the entry point to your application is named main.js, and that you'd like all imports compiled into a single file named bundle.js.

For browsers:

# compile to a <script> containing a self-executing function
rollup main.js --format iife --name "myBundle" --file bundle.js

For Node.js:

# compile to a CommonJS module
rollup main.js --format cjs --file bundle.js

For both browsers and Node.js:

# UMD format requires a bundle name
rollup main.js --format umd --name "myBundle" --file bundle.js

Why

Developing software is usually easier if you break your project into smaller separate pieces, since that often removes unexpected interactions and dramatically reduces the complexity of the problems you'll need to solve, and simply writing smaller projects in the first place isn't necessarily the answer. Unfortunately, JavaScript has not historically included this capability as a core feature in the language.

This finally changed with ES modules support in JavaScript, which provides a syntax for importing and exporting functions and data so they can be shared between separate scripts. Most browsers and Node.js support ES modules. However, Node.js releases before 12.17 support ES modules only behind the --experimental-modules flag, and older browsers like Internet Explorer do not support ES modules at all. Rollup allows you to write your code using ES modules, and run your application even in environments that do not support ES modules natively. For environments that support them, Rollup can output optimized ES modules; for environments that don't, Rollup can compile your code to other formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code, and you also get the tremendous benefits of...

Tree Shaking

In addition to enabling the use of ES modules, Rollup also statically analyzes and optimizes the code you are importing, and will exclude anything that isn't actually used. This allows you to build on top of existing tools and modules without adding extra dependencies or bloating the size of your project.

For example, with CommonJS, the entire tool or library must be imported.

// import the entire utils object with CommonJS
var utils = require('node:utils');
var query = 'Rollup';
// use the ajax method of the utils object
utils.ajax('https://api.example.com?search=' + query).then(handleResponse);

But with ES modules, instead of importing the whole utils object, we can just import the one ajax function we need:

// import the ajax function with an ES import statement
import { ajax } from 'node:utils';

var query = 'Rollup';
// call the ajax function
ajax('https://api.example.com?search=' + query).then(handleResponse);

Because Rollup includes the bare minimum, it results in lighter, faster, and less complicated libraries and applications. Since this approach is based on explicit import and export statements, it is vastly more effective than simply running an automated minifier to detect unused variables in the compiled output code.

Compatibility

Importing CommonJS

Rollup can import existing CommonJS modules through a plugin.

Publishing ES Modules

To make sure your ES modules are immediately usable by tools that work with CommonJS such as Node.js and webpack, you can use Rollup to compile to UMD or CommonJS format, and then point to that compiled version with the main property in your package.json file. If your package.json file also has a module field, ES-module-aware tools like Rollup and webpack will import the ES module version directly.

<h2>Introduction</h2>

Webpack is a bundler for modules. The main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

TL;DR

Bundles ES Modules, CommonJS, and AMD modules (even combined).
Can create a single bundle or multiple chunks that are asynchronously loaded at runtime (to reduce initial loading time).
Dependencies are resolved during compilation, reducing the runtime size.
Loaders can preprocess files while compiling, e.g. TypeScript to JavaScript, Handlebars strings to compiled functions, images to Base64, etc.
Highly modular plugin system to do whatever else your application requires.

Get Started

Check out webpack's quick Get Started guide and the other guides.

Browser Compatibility

Webpack supports all browsers that are ES5-compliant (IE8 and below are not supported). Webpack also needs Promise for import() and require.ensure(). If you want to support older browsers, you will need to load a polyfill before using these expressions.

<h2>Concepts</h2>

Plugins

Webpack has a rich plugin interface. Most of the features within webpack itself use this plugin interface. This makes webpack very flexible.

Loaders

Webpack enables the use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.

Loaders are activated by using loadername! prefixes in require() statements, or are automatically applied via regex from your webpack configuration.

Performance

Webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.

Module Formats

Webpack supports ES2015+, CommonJS and AMD modules out of the box. It performs clever static analysis on the AST of your code. It even has an evaluation engine to evaluate simple expressions. This allows you to support most existing libraries out of the box.

Code Splitting

Webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.

Optimizations

Webpack can do many optimizations to reduce the output size of your JavaScript by deduplicating frequently used modules, minifying, and giving you full control of what is loaded initially and what is loaded at runtime through code splitting. It can also make your code chunks cache friendly by using hashes.

<h3>Creating your own plugins and loaders</h3>

If you create a loader or plugin, we would <3 for you to open source it, and put it on npm. We follow the x-loader, x-webpack-plugin naming convention.

<h2>Support</h2>

We consider webpack to be a low-level tool used not only individually but also layered beneath other awesome tools. Because of its flexibility, webpack isn't always the easiest entry-level solution, however we do believe it is the most powerful. That said, we're always looking for ways to improve and simplify the tool without compromising functionality. If you have any ideas on ways to accomplish this, we're all ears!

If you're just getting started, take a look at our new docs and concepts page. This has a high level overview that is great for beginners!!

If you have discovered a 🐜 or have a feature suggestion, feel free to create an issue on GitHub.

<h2>Concepts</h2>

Plugins

Webpack has a rich plugin interface. Most of the features within webpack itself use this plugin interface. This makes webpack very flexible.

Loaders

Webpack enables the use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.

Loaders are activated by using loadername! prefixes in require() statements, or are automatically applied via regex from your webpack configuration.

Performance

Webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.

Module Formats

Code Splitting

Webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.
