log-watcher

  • Tail like utility to watch files

  • Idea is to use websockets to implement continuous file watch/follow solution

Functionalities:

  • cmd line switches
    1. -f i.e the file which is to be read
    2. -n number of lines to fetch in one go
    3. -w to watch/follow a file for changes (pending)

Components:

  • An http server to serve the file contents
  • the http server should expose a websocket endpoint, so that if user runs with follow option, the webserver should maintain a continuous connection(ws) to the client and keep on relaying file data to client
  • a cli client (using cobra) which will accept user commands and accordingly make request to http server
