  You can retrieve the client library using a dependency manager:
  
  * Maven (in your `pom.xml`):
  
  [source,xml,subs="+attributes"]
  ----
  <dependency>
    <groupId>${maven.groupId}</groupId>
    <artifactId>${maven.artifactId}</artifactId>
    <version>${maven.version}</version>
    <classifier>client</classifier>
    <type>js</type>
  </dependency>
  ----
  
  * Gradle (in your `build.gradle` file):
  
  [source,groovy,subs="+attributes"]
  ----
  compile '${maven.groupId}:${maven.artifactId}:${maven.version}:client'
  ----
  
  The library is also available on:
  
  * https://www.npmjs.com/package/vertx3-eventbus-client[NPM]
  * https://github.com/vert-x3/vertx-bus-bower[Bower]
  * https://cdnjs.com/libraries/vertx[cdnjs]
  
  Notice that the API has changed between the 3.0.0 and 3.1.0 version. Please check the changelog. The previous client
  is still compatible and can still be used, but the new client offers more feature and is closer to the vert.x
  event bus API.

  === The client side
  
  In client side JavaScript you use the SockJS client side library to make connections. For convenience the package is
  available on https://www.npmjs.com/package/sockjs-client[https://www.npmjs.com/package/sockjs-client].
  
  This means you can refer to it from bundlers or build tools. If however you want to get a `CDN` version to use directly
  on your `HTML` document, first you need to refer to the sockjs dependency:

  Full details for using the SockJS JavaScript client are on the https://github.com/sockjs/sockjs-client[SockJS website],
  but in summary you use it something like this:
  
  [source,js]
  ----
  var sock = new SockJS('http://mydomain.com/myapp');
