How to close a readable stream (before end)?

Question

How to close a readable stream in Node.js?

var input = fs.createReadStream(\'lines.txt\');

input.on(\'data\', function(data) {
   // after closing the strea

It's an old question but I too was looking for the answer and found the best one for my implementation. Both end and close events get emitted so I think this is the cleanest solution.

This will do the trick in node 4.4.* (stable version at the time of writing):

var input = fs.createReadStream('lines.txt');

input.on('data', function(data) {
   if (gotFirstLine) {
      this.end(); // Simple isn't it?
      console.log("Closed.");
   }
});
