What is that?
WebSocket is already built into modern browsers and provides bidirectional low-latency messaging.
However, as such, it is quite low-level. Web apps often have a need for higher level messaging patterns:
- Publish & Subscribe
- Remote Procedure Calls
This is where WAMP enters. WAMP runs on top of raw WebSocket and provides asynchronous RPC and PubSub.
Technically, WAMP is a proper WebSocket subprotocol that uses JSON as message serialization format. WAMP was designed to be easy to use and simple to implement.
AutobahnExtJS provides and Autobahn/WAMP proxy and support code for Sencha ExtJS. Please see the
autobahnextjs folder for code and more information.

AutobahnJS includes code from the following open-source projects
Building AutobahnJS will create a single file, minimized version of the library.
To build, you will need
SCons is a Python based build tool, so you will need Python as well.
Set environment variables:
JAVA_HOME pointing to your Java run-time, e.g.
adding Python & Python scripts to PATH, e.g.
JS_COMPILER pointing to the Google Closure compiler.jar
C:\Program Files\Google Closure\compiler.jar
Now clone the repo:
git clone git://github.com/tavendo/AutobahnJS.git
You need to include the submodules (i.e. currenlty when.js):
cd AutobahnJS git submodule init
and then update them
git submodule update
Updating CryptoJS needs to be done manually, since they are not on Git.
For a release version, set the appropriate AutobahnJS version in 'version.txt', e.g
Scons currently needs to be run from the Windows shell, so open one, go to the AutobahnJS directory, and run
This will produce 2 files
To clean up your build
Tavendo provides hosting of AutobahnJS on Amazon S3 at:
Set AWS credentials in
C:\Users\johndoe\.boto for Windows):
[Credentials] aws_access_key_id = ABCDEFGHJIKLMNOPQRTUVXYZ aws_secret_access_key = 0123456789ABCDEFGHJIKLMNOPQRTUVXYZ
You will also need Boto installed:
To publish, then do
