Nodejs line-by-line close calling next line?

Question

I'm using the plugin line-by-line to read a very large file. There's a case where I want just the first line, so I'd close the connection immediately in that case.

However, I was noticing that it would try to process the next line regardless. I dumbed it down as far as I could, and wrote this:

lr.on("line", function (line) {
  lr.pause();
  console.log("\rLine");
  lr.close();
}

My console shows:

Line

Without the lr.close(), it only logs Line once.

What am I missing?

try `lr.end();` It print last line because it already read it as `lineFragment`. — vp_arth, Nov 13 '15 at 17:19
@vp_arth That should be an answer, works as expected. Didn't see that in the doc... — Randy Hall, Nov 13 '15 at 17:23

Take a look to Source

It print last lineFragment for you.
If you don't need it - call lr.end();.
