Piping stream to a variable!? or ....?
You probably can pipe a stream to a variable, but pipe is generally used to pipe the stream to some other method that can utilize the stream, as pipe pulls all the data out of a readable stream, and writes it to the supplied destination, automatically managing the flow so that the destination is not overwhelmed by a fast readable stream.
For instance, piping a stream to a file
someReadableStream.pipe(fs.createWriteStream("result.json"));If you just want the data in a variable, there are events for that, that are probably easier to use, like on('data')
var readable = getReadableStreamSomehow(), result = '';readable.on('data', function(chunk) { result += chunk;});readable.on('end', function () { // do something with "result"});
