Message Protocol (lively-json)

1
message = {
    // REQUIRED selector for service lookup. By convention action gets
    // postfixed with "Result" for response messages
    action: STRING,
    // REQUIRED target of the message
    target: UUID,
    // OPTIONAL arguments
    data: OBJECT,
    // OPTIONAL identifier of the message
    messageId: UUID,
    // OPTIONAL sender of the message
    sender: UUID,
    // OPTIONAL identifier of a message that this message answers
    inResponseTo: UUID,
    // OPTIONAL if message is an answer. Can be interpreted by the receiver as
    // a streaming response. Lively participants (tracker and clients) will
    // trigger data bindings and fire callbacks for a message for every streaming
    // response
    expectMoreResponses: BOOL,
    // EXPERIMENTAL UUIDs of trackers/sessions handlers that forwarded this
    // message
    route: ARRAY
}

the essential part

Services

1
// this is server code:
util._extend(require("./LivelyServices").services, {
    serverSayHello: function(sessionServer, connection, msg) {
        connection.send({
            action: msg.action + 'Result',
            inResponseTo: msg.messageId,
            data: 'Hello!'});
    }
});
X

■ New server service:

1
// this is client code
var sess = lively.net.SessionTracker.getSession();
sess.sendTo(sess.trackerId, 'serverSayHello', {}, show);
X

■ New Lively world service:

1
lively.net.SessionTracker.registerActions({
    foobar: function(msg, session) {
        session.answer(msg, 'Howdy!');
    }
})
X

Lively2Lively Client Interface

1
// if not disabled a session gets established on world load
session = lively.net.SessionTracker.getSession();
// all the sessions in LivelyWeb that we know of
session.getUserInfo(inspect);
// loopback: send a message to myself
session.sendTo(session.sessionId, 'askFor', {bar: 23}, inspect);
// what services are provided by this session?
session.sendTo(session.sessionId, 'reportServices', null, inspect);
// what services are provided by my tracker?
session.sendTo(session.trackerId, 'reportServices', {}, inspect);
// how to implement a new message
// 1) messageNotUnderstood
session.sendTo(session.sessionId, 'foobar', {}, show);
// 2) Implement service
lively.net.SessionTracker.registerActions({
    foobar: function(msg, session) {
        session.answer(msg, 'Howdy!');
    }
})
// 3) message responds successfully
session.sendTo(session.sessionId, 'foobar', {}, show);
