This is a JavaScript implementation of the Web Application Messaging protocol described in this design doc.
Wam is a convention for exchanging messages built on top of existing postMessage based APIs.
Wam adds the ability to request one-or-more replies to a message, even if that message is itself a reply. These nested reply chains are a fundamental tool in wam. They are used to establish sub-channels under which the set of expected messages may redefined, and simultaneously as a way to express handles across a messaging boundary.
Wam also specifies a handshake, in which both endpoints agree on the messaging dialect to be used within the context of the handshake.
At the moment (2014-04-05) it‘s a bit fresher than the document. The wam core and wam.FileSystem implementations are in decent shape, but wam.API work hasn’t started.
The ../wash/ directory contains a Chrome V2 app that builds a bash-like command line shell out of wam.FileSystem.
