How to Install Gulp.js on Ubuntu

Step 1 – Installing Node.js

First of all, you need to install node.js on your system. Use following set of commands to add node.js PPA in your Ubuntu system and install it.

sudo apt-get install python-software-properties

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

sudo apt-get install nodejs

Make sure you have successfully installed node.js and NPM on your system

node --version

npm --version

Step 2 – Create Sample Application with NPM

Gulp can be easily use in your existing Node.js application. You just need to install Gulp package for Node.js in your project. For this tutorial, I am creating a sample Node.js application with NPM.

mkdir gulp-project && cd gulp-project

npm init

This command will prompt the required information to initialize a new empty project under the current directory.

Input all the required details for your application. At the end, it will show you the details you input and ask you to confirm.

About to write to /root/gulp-project/package.json:

{
  "name": "gulp-project",
  "version": "1.0.0",
  "description": "First gulp application by Tecadmin",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [
    "gulp",
    "app"
  ],
  "author": "TecAdmin",
  "license": "ISC"
}

Is this OK? (yes)

Just press enter to save all details in package.json file.

Step 3 – Install Gulp.js on Ubuntu

Once you have an node.js application. Use the following commands to install Gulp CLI globally on your system.

npm install -g gulp-cli

Also install the gulp package in your application. Swith to your application directory and execute the following command.

npm install --save-dev gulp

All done, Let’s check the installed version of Gulp CLI on your system and Gulp module in your application with the following command.

gulp --version

Step 4 – Gulp Hello World Example

As you have gulp package added your application and installed gulp-cli on your system.

Next, create a gulpfile.js under the application root directory.

Add a sample code of gulp hello world example program.

var gulp = require('gulp');

gulp.task('hello', function(done) {
  console.log('Hello World!!!');
  done();
})

Save your file and close.

Next run the gulp task with the following command under the application.

gulp hello

Install required gulp modules

npm install gulp-sourcemaps node-sass gulp-clean-css gulp-webserver gulp-sass gulp-ruby-sass gulp-autoprefixer gulp-minify-css gulp-rename gulp-changed gulp-imagemin gulp-concat gulp-uglify main-bower-files gulp-watch gulp-livereload browser-sync --save-dev
