Intro To Gulp

Gulp is a javascript task runner and automation tool that are typically used by developers to perform repetitive tasks typically within the CI/CD devops workflow.

Those tasks included:

CSS compilation via Less or Sass.
Move or coping files to an output directory for deployment.
Running unit testss and code analysis.
Minifying and bundling javascript libraries and CSS style sheets.

Install Gulp

The best way to install Gulp is via npm(Node Package Manager), if you are not familiar with npm please visit the www.npmjs.com for more detail.

I recommand that you install gulp from npm locally within your frontend application project. however you can also install Gulp globally if you wish.

Open a console and change directory to your project root
```
cd yourproject
```
Install Gulp on your project locally
```
npm install --save-dev gulp
```
The –save-dev option will add the package to development section of your package.json file. Since Gulp will be used to assist build and deployment automations, it is not required in the production environment.
Now it’s time to creat a test gulpfile. create a gulpfile.js in your project root with the following contents:
```
var gulp = require('gulp');
gulp.task('test-task', function(){
 console.log('success!');
});
```
Run the task by entering the command below
```
gulp test-task
```
You should get success! back as a result.
