The project can be installed via NPM, or by cloning this repo into your project.
npm install backbone-redis
or
git clone git://github.com/sorensen/backbone-redis.git
var express = require('express'),
Redis = require('redis'),
bbRedis = require('../../'),
browserify = require('browserify'),
io = require('socket.io'),
server = module.exports = express.createServer(),
io = io.listen(server);
var db = Redis.createClient(6379, '127.0.0.1'),
pub = Redis.createClient(6379, '127.0.0.1'),
sub = Redis.createClient(6379, '127.0.0.1')
bbRedis.config({
io : io,
database : db,
publish : pub,
subscribe : sub,
listener : 'backbone',
});
server.listen(8080);
You can also create schemas for your models, which will have
hookable methods for you to intercept the data. The hookable
methods are create
, read
, update
, delete
, subscribe
,
and unsubscribe
, each with both pre
and post
methods attached.
var fooSchema = bbRedis.schema();
fooSchema
.pre('create', function(next, model, options, cb) {
next(model, options, cb);
})
.post('create', function(next, model, options, cb) {
next(model, options, cb);
});
.pre('subscribe', function(next, socket, options, cb) {
next(socket, options, cb);
})
.post('subscribe', function(next, socket, options, cb) {
next(socket, options, cb);
});
bbRedis.model('foo', fooSchema);
Just be sure the name you give for the schema matches the type
attribute that you set on the Backbone model.
<script src='/socket.io/socket.io.js'></script>
<script src="/underscore.js"></script>
<script src="/backbone.js"></script>
If you have cloned the repo, just serve the file.
Otherwise you can expose it to the client using browserify
.
<script src="/backbone.redis.js"></script>
var socket = io.connect();
bbRedis.config({
io : socket,
listener : 'message'
});
var Foo = Backbone.Model.extend({
url : 'foos',
type : 'foo',
sync : _.sync
});
var FooList = Backbone.Collection.extend({
model: Todo,
url : 'todos',
type : 'todo',
sync : _.sync
});
Now that there is something to work with, we can use all of the default Backbone methods
FooList.fetch();
FooList.subscribe({}, function(){
FooList.create({
data : 'lorem ipsum'
})
FooList.unsubscribe();
});
