<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 & 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> |

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 → New…​ → Other…​</strong> and choose <strong>"Bower Init"</strong> wizard which helps to create <code>bower.json</code> file depending on a set of preferences:</p> |
