json-stringify-trough

Simply stringify a readable stream in objectMode and get that array as a complete valid JSON at readable side of transform stream.

Usefull if you want to do something like:

  res.set('Content-Type', 'application/json')
  readableObjectStream
    .pipe(new JSONStringifyTrough())
    .pipe(res)
    .on('error', ...)

Saves you 1 buffering in case where you would collect all objects into array and then JSON.stringify all that.

Write simple benchmark code and test different stringifiers

Fun with streams
