--------------------------------------
Skill Level: Committers Level (Medium to Hard)
> _changes feed with ?feed=continuous does not return valid JSON
> --------------------------------------------------------------
>
> Key: COUCHDB-604

> Project: CouchDB
> Issue Type: Improvement
> Components: HTTP Interface
> Affects Versions: 0.10
> Reporter: Joscha Feth
> Priority: Trivial
>
> When using the _changes interface via ?feed=continuous the JSON returned is
> rather
> a stream of JSON documents than a valid JSON file itself:

> to be valid there needs to be a root element (and then an array with commata)

> in short this means that if someone does not parse the change events in an
> object like manner (e.g. waiting for a line-ending and then parsing the
> line), but using a SAX-like parser (throwing events of each new object, etc.)
> and expecting the response to be JSON (which it is not, because its not
> {x:[{},{},{}]} but {}{}{} which is not valid) there is an error thrown.
> I can see, that people doing this line by line might be okay with the above
> approach, but the response is not valid JSON and it would be nice if there
> were a flag to make the response valid JSON.
