JarCastingnode-streamsink
Pipe a stream to a StreamSink, and then you can create a ReadableStream, String, or Buffer from the StreamSink.
Usage
var StreamSink = require('streamsink');
var sink = new StreamSink();
fs.createReadStream("foo.txt").pipe(sink);
sink.on('finish', function() {
// sink has now buffered foo.txt
sink.createReadStream().pipe(someDestination);
// or use toString([encoding], [start], [end])
console.log(sink.toString('utf8'));
// or use toBuffer()
sink.toBuffer();
});
// you can also create instances from a list of buffers
var sink = StreamSink.fromBufferList([new Buffer("aoeu"), new Buffer("foo")]);
