live-file is a simple utility to allow you to watch a remote file in realtime on your browser via websockets. It's not meant to be a nice finished product it's just a hacked together tool.
You can install live-file using npm. Be sure to use -g option:
npm install live-file -g
To run, all you need to do is run the command and pass it a file:
live-file --file /var/log/system.log
Point your browser at http://localhost:8888 to see the results.
You have a few extra options:
live-file --file /var/log/system.log --port 3000 --backlog 10000
--port is the webserver port and --backlog is the number of bytes to send to the client at a time.
I have only tested this on Firefox :/
I borrowed some code from around github but I can't seem to find all the sources. I know this guy was involved:
fs#watchFile seems to be kind of slow. I imagine there are better ways to do this now. I might change this soon.
