This is a simple web application I have written to watch log files from a browser. The primary motivation for its creation is for me to learn how to use WebSockets in NodeJS while creating something useful for myself. It uses WebSockets ws by einaros.

npm install -g logwatcher

Create a .logwatchrc file in your home directory. Then just run:

logwatch

Sample .logwatchrc file:

{
  "port": 4000,
  "logs": {
    "Name": "/home/user/path/to/file.log"
  }
}

Port of 4000 is default. The name is used for the button display in the browser.
