Next, create a new file called in the learn-rollup folder. To get started, install Rollup with the following command: npm install -save-dev rollup Step 1: Install Rollup and create a configuration file. The HTML isn’t discussed in this tutorial. NOTE: If you don’t clone the repo, make sure to copy the contents of build/index.html into your own code. git clone -b step-0 -single-branch # The files are downloaded to /path/to/your/projects/learn-rollup/ cd /path/to/your/projects # Clone the starter branch of the app from GitHub. # Move to the folder where you keep your dev projects. You can install the app we’ll be working with during this tutorial by running the following command into your terminal. The folder structure looks like this: learn-rollup/ ├── build/ │ └── index.html ├── src/ │ ├── scripts/ │ │ ├── modules/ │ │ │ ├── mod1.js │ │ │ └── mod2.js │ │ └── main.js │ └── styles/ │ └── main.css └── package.json For this tutorial, we’ll be working with a small app, available on GitHub. In order to get started, we need to have some code to work with. Step 0: Create a project with JavaScript and CSS to be compiled. To show how effective Rollup is, let’s walk through the process of building an extremely simple project that uses Rollup to bundle JavaScript. Part I: How to Use Rollup to Process and Bundle JavaScript Files NOTE: Due in part to Rollup’s efficiency, webpack 2 is going to include tree-shaking. But Rollup doesn’t - it’ll only bring in what we’re actually using. If we’re only using one or two - think lodash or jQuery - there’s a lot of wasted overhead in loading the rest of the library.īrowserify and webpack will end up including a lot of unused code right now. Tree-shaking becomes really important when we’re including third-party tools or frameworks that have dozens of functions and methods available. It’s also much easier for Rollup to remove unused code from modules using something called tree-shaking, which basically just means only the code we actually need is included in the final bundle. This happens because Rollup is based on ES2015 modules, which are more efficient than CommonJS modules, which are what webpack and Browserify use. This gets pretty nerdy, so the tl dr version is this: compared to the other tools for creating JavaScript bundles, Rollup will almost always create a smaller, faster bundle. What makes Rollup exciting, though, is its ability to keep files small. However, it’s important to note that while you can use Grunt and Gulp to handle tasks like creating JavaScript bundles, those tools would use something like Rollup, Browserify, or webpack under the hood. You could also call Rollup a build tool, which would put it in the company of things like Grunt and Gulp. Author your app or library using ES2015 modules, then efficiently bundle them up into a single file for use in browsers and Node.js. Rollup is a next-generation JavaScript module bundler. Part II: How to Use Rollup to Process and Bundle Stylesheets.Part I: How to Use Rollup to Process and Bundle JavaScript Files You’ll need npm installed on your machine.Initial familiarity with ES2015 modules doesn’t hurt, either. This will make more sense if you know at least a little bit of JavaScript.compress and minify our code for the smallest possible file size.support the use of Node modules in the browser,.transpile it to work with older browsers,.This week, we’re going to build our first project using Rollup, which is a build tool for bundling JavaScript (and stylesheets, but we’ll get to that next week).īy the end of this tutorial, we’ll have Rollup configured to: The code should still work, but you may want to look for a more up-to-date tutorial. Heads up: this post was written in 2016, and some of the tools and prices may have changed.
