#PRINTME APP UPDATE#
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. We'll also remove the entry point for print.js as it will now be consumed by the index.js module. 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.
