Let’s install webpack-dev-server in out project with the next command npm install webpack-dev-server -save Here is the repository link in case you want to start with the project we made in the previous chapter. Gulp.We will setup webpack-dev-server for running our project using a web server. on('error', (error) => console.log(error.toString())) Return gulp.src(settings.themeLocation + 'css/style.css') It takes modules, whether that’s a custom file that we created or something that was installed through NPM, and converts these modules to static assets. Let's say we import our main SASS file sass/styles.scss in our javascripts/index.js entry point.īrowserSync = require('browser-sync').create(),Ĭssvars = require('postcss-simple-vars'),ĬolorFunctions = require('postcss-color-function') Webpack is a static module bundler for JavaScript applications. It's a kind of "default" approach to CSS. We transform SASS to CSS and then apply auto prefixing and minifying.
Usually, we don't want to write plain CSS.

Now you can place ES6 code inside your JavaScript modules safely! How does the frontend runs in production if node does not exist as a service in docker-compose.yml and the web server. It is a separate topic on its own, and you can dive into it if you are interested, but it's safe to keep it like this for now.
In this case, we set default presets for Babel to consider which ES6 features it should transform and which not. options can vary depending on the loader.Here we set loader, which is going to be applied to files that correspond to test regexp (JavaScript files in this case)
That means we won't convert imported vendor libraries from npm if we import them in the future.
exclude is a regular expression that tells Webpack which path should be ignored when transforming modules. test is a regular expression for file extension which we are going to transform. You can simply add them in your HTML file like that (of course you should change path to dist folder if needed):Įnter fullscreen mode Exit fullscreen mode Webpack will produce 1 bundled JavaScript file and 1 bundled CSS file. We will be using Webpack to bundle our JavaScript, styles, images, and fonts files together into one dist folder. At least I would be happy to meet something like this when I started with Webpack! Although this guide requires some prior knowledge about web-development and JavaScript, it may be useful for someone. Webpack dev server should ONLY be used for. Webpack dev server is also a separate package that needs to get install via NPM. The Node.js server listens to when files were changed, and triggers events to react accordingly. It uses a library called SockJS to emulate a web socket. It should be enough to start using Webpack for most simple websites or use it as a platform for further learning. Under the hood, Webpack dev server is a mini Node.js Express server. This guide will look at step-by-step Webpack configuration for ES6, SASS, and images/fonts without any framework. There is a lack of introductory articles about Webpack and how it works, people rush straight to tools like create-react-app or vue-cli, but one sometimes needs to write some simple plain JavaScript and SASS with no frameworks or any fancy stuff. Sometimes you can be stuck at something trivial and google a lot to find some short message in GitHub issues that finally helps. Tutorials are getting old, some plugins break, found examples can be confusing. However, it is overwhelming for a new developer to learn all stuff at once. Webpack team is working really hard and relatively quickly developing it, which is a good thing. Despite having good documentation, this bundler isn't a comfortable horse to ride for a few reasons. As you may know, configuring Webpack can be a frustrating task.
