#ALTERNATIVE TO LIVERELOAD UPDATE#

This means that a single handler can update a complete module tree. If a module has no HMR handlers, the update bubbles up.

However, in most cases, it's not mandatory to write HMR code in every module. Similarly, when implementing the HMR interface in a module, you can describe what should happen when the module is updated. In order for patching to work, the style-loader implements the HMR interface when it receives an update through HMR, it replaces the old styles with the new ones. One example would be patching styling through the style-loader. HMR is an opt-in feature that only affects modules containing HMR code. with webpack-dev-server), but it's also possible to store them in a JSON file. It typically stores these IDs in memory (e.g. The compiler ensures that module IDs and chunk IDs are consistent between these builds. Each of these chunks contains the new code for all updated modules (or a flag indicating that the module was removed). The manifest contains the new compilation hash and a list of all updated chunks. One or more updated chunks (JavaScript).In addition to normal assets, the compiler needs to emit an 'update' to allow updating from the previous version to the new version. You can set up HMR so that this process happens automatically, or you can choose to require user interaction for updates to occur. The runtime synchronously applies the updates.The application then asks the runtime to apply the updates.The runtime asynchronously downloads the updates and notifies the application.The application asks the HMR runtime to check for updates.The following steps allow modules to be swapped in and out of an application: Let's go through some different viewpoints to understand exactly how HMR works. Instantly update the browser when modifications are made to CSS/JS in the source code, which is almost comparable to changing styles directly in the browser's dev tools.Save valuable development time by only updating what's changed.

Retain application state which is lost during a full reload.This can significantly speed up development in a few ways: Then, we’re defining a task named minify, which, when run, will call the function provided as the second argument: gulp.Hot Module Replacement (HMR) exchanges, adds, or removes modules while an application is running, without a full reload. First, we’re loading the gulp and gulp-uglify modules: var gulp = require('gulp'), We’re doing a few things in our gulpfile.js file. Assuming that you have a file named app.js in the js directory, a new app.js will be created in the build directory containing the minified contents of js/app.js.

Install gulp-uglify through npm by running npm install –save-dev gulp-uglify, and then run the task by running gulp minify. Put the following in your gulpfile.js file: var gulp = require('gulp'), This is where you will define your Gulp tasks, which will be run using the gulp command. Let’s create a task to minify one of our JavaScript files. Then, install it in your project: npm install -save-dev gulp First, install the package globally: npm install -g gulp Gulp is open source and can be found on GitHub. I’ve compiled a longer list of build tools written in JavaScript. Other build tools are available, such as Grunt and, more recently, Broccoli, but I believe Gulp to be superior (see the “Why Gulp?” section below). For example, there are plugins to run JSHint, compile your CoffeeScript, run Mocha tests and even update your version number. The system by itself doesn’t really do much, but a huge number of plugins are available, which you can see on the plugins page or by searching gulpplugin on npm. This makes it perfect if you’re a front-end developer: You can write tasks to lint your JavaScript and CSS, parse your templates, and compile your LESS when the file has changed (and these are just a few examples), and in a language that you’re probably already familiar with. It’s built on Node.js, and both the Gulp source and your Gulp file, where you define tasks, are written in JavaScript (or something like CoffeeScript, if you so choose). Gulp.js is a build system, meaning that you can use it to automate common tasks in the development of a website.
