How to do `tail -f logfile.txt`-like processing in node.js?

Question

tail -f logfile.txt outputs the last 10 lines of logfile.txt, and then continues to output appended data as the file grows.

What\'s the recommended way

Answer 1

node.js APi documentation on fs.watchFile states:

Stability: 2 - Unstable. Use fs.watch instead, if available.

Funny though that it says almost the exact same thing for fs.watch:

Stability: 2 - Unstable. Not available on all platforms.

In any case, I went ahead and did yet another small webapp, TailGate, that will tail your files using the fs.watch variant.
