This was implemented for a real world application that was pulling in a large amount of data from multiple databases (SQL and MongoDB).

In order to improved TTFP (time to first page of results) and thus user-perceived performance, the API was converted to stream the results objects as it completed them.

Oboe.js allowed us to take advantage of that streaming API by parsing the incoming JSON stream on the browser-side.
