    stream-pass

    Manable multiple streams and their ends easily.

    It uses through and concat-stream to pipe and produce results to callback.

    Examples

    Using child_process.spawn :

    var streamPass = require('stream-pass'), child_process = require('child_process');
     
    var pass = streamPass(function(results) {
      console.log('stdout was: '+results.stdout.toString());
      console.log('2nd line of stderr was: '+results.stderr.toString().split(/\n/)[1]);
    }, ['stderr', 'stdout']);
     
    var child = child_process.spawn('wget', ['-O', '-', 'http://httpbin.org/user-agent']);
     
    pass.passStream('stdout', child.stdout);
    pass.passStream('stderr', child.stderr);
     
    // stdout was: {
    //   "user-agent": "Wget/1.15 (linux-gnu)"
    // }
    //
    // 2nd line of stderr was: Resolving httpbin.org (httpbin.org)... 54.175.219.8

    You can also pipe the streams :

    var streamPass = require('stream-pass');
    var pass = streamPass(function(results) { ... }, ['myStream']);
    pass.passStream('myStream', myStreamObject);
    pass.getStream('myStream').pipe(process.stdout);

    Or add some :

    var streamPass = require('stream-pass');
    var pass = streamPass(function(results) { /* do something with results.myStream */ });
    pass.addStream('myStream');
    pass.passStream('myStream', myStreamObject);

    To do

    • anyStream.pipe(pass.getStream('myStream')) brokes the callback
    • passStream() without addStream() before

    install
