This module is designed to follow a file which is being appended to by something like a syslog server. It will reopen the file if the file is truncated and recover from file being removed and recreated.


This module comes with a small command which will follow the file, this is used for demonstration and testing purposes.

follow-file -f /var/log/syslog


As illustrated in the following example program this module can be used as an endless stream. Note in this example I am using through to inject new lines for presentations sake.

ff(argv.file).stream.pipe(through(function write(data) {
     log('data', data)
     this.emit('data', data + '\n')
   function end() { //optional
