Backbone.WAMP replace your classic REST protocol, based on AJAX, to modern WAMP protocol, based on WebSockets. You can read more about here.

you need eastablish autobahn connection and link it to global WAMP_CONNECTION or
specific wampConnection for WampModel / WampCollection.

};
WAMP_CONNECTION.open();When you create instances of WampModel / WampCollection, this automatically
register listeners, using wampMyId / WAMP_MY_ID and urlRoot / url, if it present.
For ignoring this, need pass to constructor - wampNoAttach option.
For catching each registering need pass to constructor - wampRegister callback-option.

url: "ws://127.0.0.1:9000/ws",

var model2 = new Model2({}, {wampNoAttach: true}); // no register listeners, pass specific option
model2 = new Model2({}, {wampRegister: function (errOrReg) { // register listeners
// calling for registering each action: create | read | update | delete | patch
}})
};
WAMP_CONNECTION.open();This hooks automatically registers, when create instances of WampModel / WampCollection,
if exists wampMyId / WAMP_MY_ID and urlRoot / url and not pass wampNoAttach option.
sendOptions.data contains JSON-parsed model for create, update, patch actions.
Or GET-params for read action of model/collection.
sendOptions.extra contain any extra information, which you can send in options.wampExtra
Built-in options in sendOptions.extra:
wampModelIdof specific model, if neededwampMyIdof another environment
Need return data or promise, that resolved to data.
For error need return new autobahn.Error(...) or promise, that resolve new autobahn.Error(...)
For example, see Overview example above.
By default, via methods save, fetch, e.t.c. generated WebSocket messages as is peerId.uri.action
Example: "nodejs.test_collection.create"
You can overwrite template if needed via wampGetUri / WAMP_GET_URI, that
When defined, will be called before wampCreate, wampRead, wampUpdate, wampDelete, wampPatch.
If it's return non true value or promise, that resolved to non true,
wampCreate, wampRead, wampUpdate, wampDelete, wampPatch not be called.
uriOptions contain peerId, uri, action
more about sendOptionsin wampCreate, wampRead, ... partition
global.WAMP_MY_ID = "nodejs";
global.WAMP_CONNECTION = new autobahn.Connection({
url: "ws://127.0.0.1:9000/ws",

// it pseudo code with concept
return new Promise(function (resolve) {
db.find({peer: sendOptions.extra.wampMyId}).then(function (finded) {
resolve(finded) // if finded === true, auth passed
})
});
},
wampRead: function () {
// this called, if wampAuth return promise, that resolved to true
}
});
var collection = new Collection();
};
WAMP_CONNECTION.open();This can be useful for wampAuth.
For session mechanism need dynamically generate wampMyId.
Example: browser_0dbee552-46e0-4c7c-aa4e-e1341dc00b18
Use any UUID, GUID, e.t.c. generator, maybe node-uuid
Call this method directly on instances of WampModel / WampCollection for unregistering
wampCreate, wampRead, ... methods.

If omitted, will unregister all actions
callback called per each unregistering action
