Randy

Randy is a country singer that sends notifications, drives a Trans Am, and will shoot you with his invisble gun.

Installation

npm install node-randy

Server Setup

Randy setup is rather simple. To get a notifications server up and running simply:

var randy   = require('node-randy');
randy.listen(80, function (err) {
    // Let's do this!
});

Optionally, you can pass in Redis connection settings (see Matt Ranney's Redis module for details):

var randy   = require('node-randy');
randy.listen(80, {
    port:       3333,
    host:       '127.0.0.1',
    pass:       'wildturkey',
    options:    null
}, function (err) {
    // Jump the general lee off a cliff
});

Submitting A Notification

A minimal notification is just simply a message that will be emitted immediately to all users and will not require a "dismiss" action:

var randy   = require('node-randy');
randy.submit({
    message:    'Shout it from the rooftops!'
}, function (err) {
    // Yeeeeeee hawwwwwwww! 
});

Optionally, both a target and the persist flag can be specified to send a notification to a single user and/or require a dismiss action:

var randy   = require('node-randy');
randy.submit({
    message:    'Psst. Hey... wanna party?',
    target:     'guest::user1234',
    persist:    true
}, function (err) {
    // Trans Am! 
});

Client Setup

The client side is vanilla socket.io and only requires handling of three actions: register, notice, and dismiss (and read optionally). For example:

var socket  = io.connect('//localhost');
var user    = 'test::user1234';

// Emit the "register" event with a unique user id and type (optional).
socket.emit('register', user);

// If a notice is received, display it!
socket.on('notice', function (notice) {
    alert(JSON.stringify(notice));

    // You can flag a persistent notice as "read", by emitting the "read" action
    socket.emit('read', {
        id:     notice.id,
        uid:    user
    });

    // In order to remove a persistent notice, you need to emit the "dismiss" action
    socket.emit('dismiss', {
        id:     notice.id,
        uid:    user
    });
});

Notice Model

Notices follow a very simple convention allowing for arbitrary extension through the "message" object:

{
    "id": "beb62c35-252e-44ec-9083-fd44a1e51a9f",
    "stamp": "2012-08-13T15:06:40.097Z",
    "read": false,
    "persist": false,
    "target": "test::1234",
    "message": "Hello World"
}

{
    "id": "beb62c35-252e-44ec-9083-fd44a1e51a9f",
    "stamp": "2012-08-13T15:06:40.097Z",
    "read": true,
    "persist": false,
    "target": "test::1234",
    "message": {
        "foo": "bar",
        "nyan": "cat",
        "country": {
            "music": "rules"
        }
    }
}
