Ws-Filewatcher is a cli that will watch for file change and open a websocket server where it will send a message everytime the file is updated
Here are the instruction to install the cli globally, but you can do it locally on your projects.
npm i -g ws-filewatcher
OR
yarn global add ws-filewatcher
Here is the minimum you need to write to launch the service:
ws-filewatcher -f path/to/my/file
