Restart Rails server automatically after every change in controllers

Question

It should not be necessary to restart Rails server after any normal change. However, when I make little changes on my app controllers, they aren\'t applied if I don\'t resta

You can use nodemon for auto restarting your old rails applications.

1) Install nodemon.

sudo npm install -g nodemon

2) Create nodemon.json file on root dir and configure it

{
  "ignore": [
    ".git",
    "node_modules/**/node_modules"
  ],
  "watch": [
    "app/controllers/",
    "app/models/",
    "app/assets/",
    "config/",
    "db/"
  ],
  "ext": "rb yml js css scss"
}

3) Create rails.sh file on root dir to start rails application using nodemon.

kill -9 `cat tmp/pids/server.pid`
echo "APP READY!!!"
echo "Ruby on Rails"
rails s -d

4) Give permission to rails.sh file.

sudo chmod +x rails.sh

5) Start server using sh command.

nodemon -L --exec "./rails.sh"
