##API documentation

flowers.relayReadStream()

Also available as javascript constructor at flowers.RelayReadStream()

Will return a ReadStream object there does except for relaying pipe output.

The main usercase is that you expose function there don't have a callback but returns a stream. However you have to do an async operation before createing the readstream, so you can't return the stream object directly.

exports.read = function () {
  var relay = flowers.relayReadStream();

  process.nextTick(function () {
    fs.createReadStream('file.txt').pipe(relay);
  });

  return relay;
};

flowers.buffer2stream(buffer, options)

Also available as javascript constructor at flowers.Buffer2stream()

Takes a buffer or string and splits it up intro chunks there is emitted in a ReadStream object.

The options object takes a chunkSize property there tell how big each chunk should be in bytes. By default this is 64 * 1024.

var stream = flowers.buffer2stream(buffer);

stream.pipe(fs.createWriteStream('file.txt'));
};

flowers.stream2buffer(stream, callback)

Takes a ReadStream and buffer it up until the stream is closed or an error occurred. The buffer is then send as a callback argument.

The callback have two arguments error and buffer.

The options object takes a chunkSize property there tell how big each chunk should be in bytes. By default this is 64 * 1024.

var stream = fs.createReadStream('file.txt');

flowers.stream2buffer(stream, function (error, buffer) {

});
