node-jsonstream

streaming JSON.parse and stringify

JSONStream.parse(pattern, map) provide a function that can be used to map or filter the json output. map is passed the value at that node of the pattern, if map return non-nullish (anything but null or undefined) that value will be emitted in the stream. If it returns a nullish value, nothing will be emitted. JSONStream also emits 'header' and 'footer' events, the 'header' event contains anything in the output that was before the first match, and the 'footer', is anything after the last match.
