Sync Function API

The sync function is the core API you'll be interacting with on the Sync Gateway. For simple applications it may be the only server-side code you need to write. For more complex applications it will still be a primary touch point for managing data routing and access control.

Default function

If you don't supply a sync function we'll use this as a default:

function (doc) {
  channel(doc.channels);
}
