Before we delve into configuring tasks, we need to install gulp:
$ npm install gulp -g
This installs gulp globally, giving access to gulp’s CLI. We then need to install it locally to the project.cd into your project and run the following (make sure you have an existing package.json file):
$ npm install gulp --save-dev
This installs gulp locally to the project and saves it to the devDependencies in the package.json file.

var gulp = require(‘gulp‘), gulp.task(‘default‘, function(){ console.log(‘hello, gulp!‘); });
$ gulp
The default task will run and do nothing.
