Streams2 "tail -f" until stopped
Continuously read from a growing file until stopped.
This is similar to other modules, however it requires an explicit
done() signal before it stops checking and finally ends.
Simply replace the
fs.createReadStream() call with
var tailstream = require('tailstream'); var r = tailstream.createReadStream(…);
Now consume it as a stand file
Readable however you desire. Once you no longer have any interest in the file, call
done() on it. This will trigger a final check before ending.
npm install tailstream
