Ractive Couch

Easy couchdb data binding with mustache syntax. Bind your mustache templates to a couchdb document, or view, and watch it get updated via the couchdb changes feed. Works in browser, nodejs, amd, commonjs, couchapps, and cors-couchapps.

Ractive Couch uses Ractive. If the use cases below dont work for you, it's easy to use Ractive to make something do what you want.

        el: 'pane1',
        template: template
    });
