Notify filesystem changes to your dev enviroment. Watch locally and notify to a remote server.

fsn FileSystem Notifier

fsn-toucher and fsn-watcher are two little binaries to propagate filesystem notification changes from one computer to another.

Motivation

This allow you to run your build system (as webpack, grunt or gulp) in watch mode inside your VM or container (vagrant, docker) and be notified by changes.

Server fsn-toucher inside your vagrant

Usually default options are ok:

$ vagrant ssh
 # inside your vagrant
$./fsn-toucher 
 fsn-toucher server listening on 0.0.0.0:9595

Watcher fsn-watcher in your local computer

You must specify the ip and optionally the port where your fsn-toucher server is running (192.168.100.100 in this case)

$./fsn-watcher --help

  Usage: fsn-toucher [options] <watch-dir> [remote-dir]


  Options:

    -V, --version        output the version number
    -i, --ip [ip]        Toucher server ip to notify
    -p, --port [port]    Toucher server port to notify
    --ignore <patterns>  <patterns> Ignored patterns separated by ,
    -h, --help           output usage information

$./fsn-watcher --ip 192.168.100.100 ~/my-projects/fsn /var/www/fsn/

Remote toucher: 192.168.100.100:9595
Remote dir: /var/www/my-projects/fsn/
Watch dir: /home/chulo/my-projects/fsn
Ignored patterns:  /node_modules/

Trying connection: 192.168.100.100:9595
Connected:  192.168.100.100:9595
Waiting for file changes

Now when you locally change something inside ~/my-projects/fsn the fsn-toucher server will be notified and will touch the file to change the access time.
