Note: The -y flag creates the file with default settings, and means you don’t need to complete any of the usual details from the command line. This will be your folder.Ĭreate a package.json file with this: npm init -y To ensure these are consistently repeatable, a build system is needed to initiate the steps in a known sequence from a single command.Ĭreate a root folder somewhere on your computer and navigate into it from your terminal/command line. This may include steps such as transpiling code to a differing standard, compiling Sass to CSS, bundling files, minifying and compressing code, and many others. The purpose of a build system is to automate the workflow needed to get our code ready for browsers and production. In turn, this means that if you’re writing modern JavaScript today, you’ll need to introduce a build step into your process.Īs you can see from the links beneath, converting down from ES6 to ES5 dramatically increases the number of browsers that we can support. Browser support for newer language features is often patchy, and as JavaScript apps become more ambitious, developers are starting to use modules to organize their code. However, since the introduction of ES6, things have got progressively more complicated. In the good old days, we could drop a couple of tags into a page, maybe include jQuery and a couple of plugins, then be good to go. JavaScript, like most web-related technologies, is evolving all the time. This is needed to ensure that our modern JavaScript code in particular is made compatible with a wider range of browsers than it might otherwise be. In this article, we’re going to look at creating a build setup for handling modern JavaScript (running in web browsers) using Babel and webpack.
