Creating diffs for Backbone.js models with Symmetry is easy. Applying them, however, is not. This module implements a best effort patch function.
Simply apply a patch to a model or collection, and events are fired:
model = new Backbone.Model();
SymmetryBB.patch(model, patch);
For nested objects, either set your models and collections in advance:
scope = {
people: new Backbone.Collection()
};
SymmetryBB.patch(scope, patch);
Or replace objects and arrays with similar models and collections:
scope = {
people: []
};
scope.people = new Backbone.Collection(scope.people);
SymmetryBB.patch(scope, patch);
While traversing, patch will try to preserve existing models and
collections, firing events on them as they change.
In node.js, install using NPM:
npm install symmetry-bb
In the browser, simply include patch.js.
git clone https://github.com/Two-Screen/symmetry-bb.git
cd symmetry-bb
npm install
npm test
