If you go ahead and click the button on the example page, you will realize the console is printing the old printMe function. In Angular you run the live reload server with: ng serve using the Angular CLI. To show this, let's go back to our working example. Turns out - there's an easier way: It's quite easy set up the WebPack Web Server to externally expose an IP address, which would allow your phone to access the live reload server over the local network. If you're using webpack-dev-middleware, check out the webpack-hot-middleware package to enable HMR on your custom dev server. Let's learn about webpack, live-reloading, Hot Module Replacement, creating NPM scripts and more.0:00 Intro1:02 Getting Started15:39 Configuration21:14 devSe. See the full documentation of webpack-dev-server Node.js API. Now let's update the index.js file so that when a change inside print.js is detected we tell webpack to accept the updated module.Ĭonst element = document.createElement('div') Ĭonst btn = document.createElement('button') Įlement.innerHTML = _.join(, ' ') ītn.innerHTML = 'Click me and check the console!' You can use the CLI to modify the webpack-dev-server configuration with the following command: webpack serve -hot-only. + new webpack.HotModuleReplacementPlugin(), + client: 'webpack-dev-server/client/index.js?hot=true&live-reload=true', + // Dev server client for web socket transport, hot and live reload logic + // Runtime code for hot module replacement You can also provide manual entry points for HMR: const path = require('path') Ĭonst HtmlWebpackPlugin = require('html-webpack-plugin') If you took the route of using webpack-dev-middleware instead of webpack-dev-server, please use the webpack-hot-middleware package to enable HMR on your custom server or application. Since webpack-dev-server v4.0.0, Hot Module Replacement is enabled by default. Reloads browser when watching any assets changes, friends with html-webpack-plugin. We'll also remove the entry point for print.js as it will now be consumed by the index.js module. A free, fast, and reliable CDN for html-webpack-live-reload-plugin. All we need to do is update our webpack-dev-server configuration, and use webpack's built-in HMR plugin. See the building for production guide for more information. HMR is not intended for use in production, meaning it should only be used in development. This page focuses on implementation while the concepts page gives more details on how it works and why it's useful. It allows all kinds of modules to be updated at runtime without the need for a full refresh. Hot Module Replacement (or HMR) is one of the most useful features offered by webpack. This guide extends on code examples found in the Development guide.
