![]() ![]() Then, we’re defining a task named minify, which, when run, will call the function provided as the second argument: gulp. 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. Based on project statistics from the GitHub repository for the npm package gulp-livereload, we found that it has been starred 773 times, and that 1,925 other projects in the ecosystem are dependent on it. ![]() As such, we scored gulp-livereload popularity level to be Recognized. Put the following in your gulpfile.js file: var gulp = require('gulp'), The npm package gulp-livereload receives a total of 45,155 downloads a week. 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 CSS injected into page USING Requires global gulp and gulp-cli to be installed Also requires node/npm, obvs. Gulp is open source and can be found on GitHub. Live reload enabled watchers for everything. 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 instance is a 'mini-lr' instance that this wraps around. gulp-livereload also reveals the underlying server instance for direct access if needed. 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. You can also directly access the middleware of the underlying server instance (mini-lr.middleware) for hookup through express, connect, or some other middleware app. Then we modify our gulpfile.js, by importing gulp-livereload. Gulp keeps things simple and makes complex tasks manageable using. 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. npm i -save static-server In you project root directory create a file and call it server.js, it should look like this. Gulp automates and enhances your application workflow. 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). You can find the full code as an example on my git is a build system, meaning that you can use it to automate common tasks in the development of a website. ![]() In the last article we ended up with gulpfile.js that looks like this const = require("gulp") Ĭonst cleanCSS = require("gulp-clean-css") Ĭonst liveReload = require("gulp-livereload") Įfault = series(minif圜SS, minifyJS) we agree that to access a task we either run gulp for public tasks or just gulp to run the default flow.īut to be honest, it's a little bit tedious to run the command every time we modify a file, whether it's a big or a small change, don't worry gulp has an easy way to keep watching for files changes and run any task you specify. In the previous article, we talked about gulpjs and we managed to create a couple of gulp tasks. ![]()
