Why does concat-stream not work with process.stdin.pipe ()?

Question

Here is my code:

var concat = require('concat-stream');
process.stdin.pipe(concat(function(){console.log("output")}));

What I expect from this is to output "output" every time I enter console input, but this does not work. Does anyone have an idea why this is not working? If I create an fs.createReadStream () buffer, it works fine, just not with process.stdin.pipe (). However, I used process.stdin.pipe () for other things, and they worked just fine.

Thanks in advance!

The reason you are not getting an exit is because you are not actually closing the stdin, which is concat-streamto ensure that it does not know that there will be no more data.
