eclipse newsletter may 2016 - JSDT 2.0 (Grunt / Gulp)

JSDT 2.0 (Grunt / Gulp)

Nowadays Front-end developers have to handle a lot of routine in every single project. Here just a few examples:

  • CSS compressing

  • Compiling Sass into CSS

  • JavaScript minification

  • Concatenating css / js files into a singe one for production

In order to automate this repetitive work JavaScript Build Systems / Task Runners were created. At the moment the most popular are Gulp and Grunt.

Pre-Requirements

Eclipse Grunt / Gulp tools use the system installation, hence the following software must be pre-installed:

  • Node.js

  • npm

  • gulp-cli (npm install -g gulp-cli)

  • grunt-cli (npm install -g grunt-cli)

Tip
Installation instructions for Node.js and npm can be found here.
Note
gulp-cli/ grunt-cli do not install Grunt / Gulp on the system, but rather in charge of running the specific version of Gulp / Grunt installed in the project (defined in package.json). This allows having multiple versions support on the same machine simultaneously.

Quick Start Guide

First thing one should do is to define all required dependencies in package.json. Both Gulp and Grunt have massive plugin library that can satisfy most, if not all, of developers' needs:

grunt / gulp dependencies

After that npm Install should be executed. This command installs all the dependencies to the node_modules folder:

Dependencies installation

Now is a hight time to start working with Gruntfile.js / gulpfile.js and define tasks. All tasks will be available in the Project Explorer view under Gruntfile.js / gulpfile.js:

gulp task

For running a task just right-click on it → Run As → Gulp / Grunt Task

Running gulp task

The execution output will be available in the Console View:

Console output

Demo

Here is a short demo video covering Eclipse Gulp / Grunt tools functionality:

Tip
The source code is available on GitHub

How to give it a go ?

Gulp / Grunt tools are available via Eclipse IDE for Java EE Developers / Eclipse IDE for JavaScript and Web Developers developer builds before the official Neon release.

<p>Nowadays Front-end developers have to handle a lot of routine in every single project. Here just a few examples:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>CSS compressing</p>
</li>
<li>
<p>Compiling Sass into CSS</p>

<p>JavaScript minification</p>
</li>
<li>
<p>Concatenating css / js files into a singe one for production</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>In order to automate this repetitive work JavaScript Build Systems / Task Runners were created. At the moment the most popular are <a href="http://gulpjs.com/">Gulp</a> and <a href="http://gruntjs.com/">Grunt</a>.</p>

<code>gulp-cli</code>/ <code>grunt-cli</code> do <strong>not</strong> install Grunt / Gulp on the system, but rather in charge of running the specific version of Gulp / Grunt installed in the project (defined in <code>package.json</code>). This allows having multiple versions support on the same machine simultaneously.

<p>First thing one should do is to define all required dependencies in <code>package.json</code>. Both Gulp and Grunt have massive plugin library that can satisfy most, if not all, of developers' needs:</p>

<div class="imageblock">
<div class="content">
<img src="dependencies.png" alt="grunt / gulp dependencies">

<p>After that <code>npm Install</code> should be executed. This command installs all the dependencies to the <code>node_modules</code> folder:</p>
