Overrides for Backbone to use CouchDB for Model persistence. Intended for server-side use of Backbone like in Bones.
npm install backbone-couch
var Backbone = require('backbone');
// Create a new backbone-couch handler for a database 'documents'.
var couch = require('backbone-couch')({
host: '127.0.0.1',
port: '5984',
name: 'documents'
});
// Create database, push default design documents to it and
// assign sync method to Backbone.
couch.install(function(err) {
Backbone.sync = couch.sync;
});
// Backbone.sync will now load and save models from a 'documents' couch db.
backbone-couch stores models in using the model.url as its _id.
By default, Collections retrieve models by matching the Collection url against
the initial portion of the Model url. See backbone.json for the default
design document and collection view.
var orange = new FruitModel({id: 'orange'});
var apple = new FruitModel({id: 'apple'});
var banana = new FruitModel({id: 'banana'});
console.log(orange.url()); // fruits/orange
console.log(apple.url()); // fruits/apple
console.log(banana.url()); // fruits/banana
var fruits = new FruitCollection();
console.log(fruits.url); // fruits
fruits.fetch(); // retrieves orange, apple, banana
To override the default design doc with your own special sauce use the doc
option when calling couch.install().
// Pass a filepath to your design doc.
couch.install({doc: '/path/to/my/doc.json'}, callback);
// Or provide a literal js object directly.
couch.install({doc: {
_id: '_design/backbone',
language: 'javascript'
}, callback);
Your design doc should use _design/backbone as its _id. Collections will be
called against this design doc using their url. For example, if you have a
Collection /blog/recent, your design doc should provide a rewrite rule to
respond to this path:
{
"_id":"_design/backbone",
"language":"javascript",
"views": {
"recent": {
"map": "function(doc) { emit(doc._id, doc._id) }"
}
},
"rewrites": [
{
"from": "/blog/recent",
"to": "_view/recent",
"query": {
"limit": "10"
"include_docs": "true"
}
}
]
}
See the rewrite handler docs or this blog post for more info on design doc rewrites.
