AutobahnJS is a JavaScript client library that implements The WebSocket Application Messaging Protocol (WAMP)
npm install @oroinc/autobahnjsAutobahnJS is a JavaScript client library that implements The WebSocket Application Messaging Protocol (WAMP):
* implements WAMP v1, works with any WAMP server
* provides asynchronous RPC and PubSub messaging patterns
* easy to use Promise-based API
* pluggable promises/deferreds: use when.js (built-in), jQuery, Dojo or others
* flexible, automatic reconnect
* session authentication (WAMP-CRA)
* no dependencies
* tiny size (97kB source, 27kB minified, 9kB compressed)
* Open-Source (MIT License)

1. Production (minimized and gzipped)
2. Production (only minimized)
3. Development
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.
AutobahnJS implements WAMP in JavaScript to be used in browser based applications.
ExtJS Extension
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
Special thanks to the Coders with an Unhealthy Javascript Obsession for creating when.js - A lightweight Promise and when() implementation, plus other async goodies.
Building AutobahnJS will create a single file, minimized version of the library.
To build, you will need
* Google Closure Compiler
* SCons
SCons is a Python based build tool, so you will need Python as well.
Set environment variables:
1. JAVA_HOME pointing to your Java run-time, e.g.
C:\Program Files\Java\jre7
2. adding Python & Python scripts to PATH, e.g.
C:\Python27;C:\Python27\Scripts;
3. 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
vi version.txt
Scons currently needs to be run from the Windows shell, so open one, go to the AutobahnJS directory, and run
scons
This will produce 2 files
build/autobahn.js
build/autobahn.min.js
To clean up your build
scons -uc
Tavendo provides hosting of AutobahnJS on Amazon S3 at:
https://autobahn.s3.amazonaws.com/js/
Set AWS credentials in $HOME/.boto (or C:\Users\johndoe\.boto for Windows):
[Credentials]
aws_access_key_id = ABCDEFGHJIKLMNOPQRTUVXYZ
aws_secret_access_key = 0123456789ABCDEFGHJIKLMNOPQRTUVXYZ
You will also need Boto installed:
easy_install boto
To publish, then do
scons publish
