• How it works

1. When server starts, it begin monitoring a log file (located as 'test_file.txt' in project root) and continuously broadcasts changes in given file to "logs" channel
2. When users visits "/?user_id=1", the webpage subscribes to "user_1" channel and server then continuously broadcasts changes to "users_1" channel
3. similarly for "/?user_id=2"
