OperationQueue.js

A reusable operation queue for saving Backbone models to the server. Currently used in the content editing infrastructure for administrators on the Khan Academy website.

Features

  • Implemented as a mixin for any existing Backbone model class.
  • Queues up changes to Backbone models to send to the server via the standard model save() method.
  • Agnostic to where the models are loaded from or any other functionality besides saving.
  • Operations are represented by a callback function + data that is applied to the model attributes at save time.
  • Special handling for a status code 409/Conflict returned from server to refresh the model and retry.

See operation-queue.js for documentation and details.

Also check out my blog post concerning the motivation and design of this feature.
