    JSDT 2.0 (Bower / npm / JSON editor)


There has been no news for quite a while from the Eclipse JavaScript Development Tools (JSDT). Basically, the project was in a deep support phase for a couple of years. However, the situation has changed dramatically and now we are glad to say that the JSDT project has been officially rebooted. This article, which is dedicated to Bower, npm & JSON editor, is the opening one of the JSDT 2.0 series.


Introduction


Bower and npm are considered to be the most popular JavaScript package managers. Bower focuses on pure front-end, whereas npm mainly deals with Node.js modules. The main advantages of using package managers are:


Dependencies are defined in a single manifest file: bower.json / package.json


No need to commit dependencies to version control repository


Easy to distribute among	team members


Tip


Even though npm is mainly used for managing Node.js modules, many developers prefer using it together tools such as Browserify for front-end development as a substitution of Bower. Also many use both: Bower for client-side packages / npm for server-side packages and JavaScript tools like grunt / gulp etc.


Pre-Requirements


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


Node.js


npm


Bower


Tip


Installation instructions for Node.js and npm can be found here. Bower is a command line utility which is installed via npm command npm install -g bower


Quick Start Guide


Getting started with JavaScript package manager is pretty straightforward. In order to start working with Bower one need to select File → New… → Other… and choose "Bower Init" wizard which helps to create bower.json file depending on a set of preferences:


After pressing "Finish" button bower.json will be created under specified directory.


In order to add new dependencies user needs to specify them in bower.json via JSON editor.


JSON Editor provides the following functionality:


Syntax Coloring (customizable via preferences)


Content assist


Outline support


Text hovering on JSON Objects' / Array' keys and values


Text folding on JSON Objects and Arrays


Editor extensions for custom hyperlinks, json schema validation & hover help


For installing specified dependencies just right-click on the bower.json → Run As… → Bower Install


After the command execution specified packages will be available under bower_components folder:


Basically, that is it - JavaScrtipt libraries / frameworks are ready for future front-end development.


Tip


npm support is implemented in a very similar way. There is a wizard for creating package.json (File → New… → Other… → npm Init) and npm Install / npm Update launch shortcuts for commands execution


Demo


Here is a short demo video covering Bower, npm and JSON editor functionality:


Tip


The source code is available on GitHub


How to give it a go ?


Bower, npm & JSON editors are available via Eclipse IDE for Java EE Developers / Eclipse IDE for JavaScript and Web Developers developer builds before the official Neon release.


To be continued…


Many more things have been implemented as a part of JSDT 2.0 release. In the next articles other enhancements and new features will be covered: ECMAScript 6 support, Node.js development and JavaScript Build Tools. Stay tuned!

<p>There has been no news for quite a while from the <a href="https://eclipse.org/webtools/jsdt/">Eclipse JavaScript Development Tools</a> (JSDT). Basically, the project was in a deep support phase for a couple of years. However, the situation has changed dramatically and now we are glad to say that the JSDT project has been officially rebooted. This article, which is dedicated to Bower, npm &amp; JSON editor, is the opening one of the <code>JSDT 2.0</code> series.</p>

<p>Bower and npm are considered to be the most popular JavaScript package managers. Bower focuses on pure front-end, whereas npm mainly deals with Node.js modules. The main advantages of using package managers are:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Dependencies are defined in a single manifest file: <code>bower.json</code> / <code>package.json</code></p>
</li>
<li>
<p>No need to commit dependencies to version control repository</p>
</li>
<li>
<p>Easy to distribute among	team members</p>

</ul>

<td class="content">
Even though npm is mainly used for managing Node.js modules, many developers prefer using it together with <a href="http://browserify.org/">Browserify</a> for front-end development as a substitution of Bower. Also many use both: <code>Bower</code> for client-side packages / <code>npm</code> for server-side packages and JavaScript tools like grunt / gulp etc.

<p>Getting started with JavaScript package managere is pretty straightforward. In order to start working with Bower one need to select <strong>File &#8594; New&#8230;&#8203; &#8594; Other&#8230;&#8203;</strong> and choose <strong>"Bower Init"</strong> wizard which helps to create <code>bower.json</code> file depending on a set of preferences:</p>

</div>
<div class="paragraph">
<p>After pressing <strong>"Finish"</strong> button <code>bower.json</code> will be created under specified directory.</p>
</div>
<div class="paragraph">
<p>In order to add new dependencies user needs to specify them in <code>bower.json</code> via JSON editor.</p>
</div>
<div class="imageblock">
<div class="content">

<p>JSON Editor provides the following functionality:</p>

<ul>
<li>
<p>Syntax Coloring (customizable via preferences)</p>

<li>
<p>Content assist</p>

<li>
<p>Text hovering on JSON Objects' / Array' keys and values</p>

<p>Text folding on JSON Objects and Arrays</p>
</li>
<li>
<p>Editor extensions for custom hyperlinks, json schema validation &amp; hover help</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>For installing specified dependencies just right-click on the <code>bower.json</code> &#8594; <strong>Run As&#8230;&#8203;</strong> &#8594; <strong>Bower Install</strong></p>
