Provides sync behavior for updating data from ampersand models and collections to the server.


Standalone, modern-browser-only version of Backbone.Sync as Common JS module.

You probably won't use this directly, but it is used by ampersand-model and ampersand-rest-collection to provide the REST functionality.

In moving from 1.0.1 to 1.0.2 we switched the underlying ajax implementation from jQuery's ajax to xhr. This changed slightly the options, as well as how ajaxConfig in models/collections operated when configured as a function.

Previously ajaxConfig would be passed the current ajax parameters object for modification, now it receives no arguments and should just return options to be merged in to the ajax parameters which will be passed to xhr.

This should have been a major release both for this module and its dependents (ampersand-model, ampersand-rest-collection, ampersand-collection-rest-mixin), but unfortunately we made a mistake and published as 1.0.2, and were too slow to rollback our mistake before workarounds were in place.

As such we are leaving the current 1.0.x versions in place, but deprecated, and suggest people upgrade to the latest versions of model/collection when they can which will contain the new implementation of xhr.

This should only affect your if you're using ajaxConfig as a function. If so you'll need to return the options you want to add, rather than expecting to be passed a params object to your ajaxConfig function.

Part of the [Ampersand.js toolkit]( for building clientside applications.
npm install ampersand-sync
npm test

Tests are written in tape and since they require a browser environment it gets run in a headless browser using phantomjs via tape-run. Make sure you have phantomjs installed for this to work.

You can also run npm start then open a browser.
