  Monitor for any changes in your node.js application and automatically restart the server - perfect for development

For those who are not aware of it, nodemon is a tool that helps develop NodeJs based applications by automatically restarting the node application when file changes in the directory are detected. We can simply install it globally and use it throughout our system without making any additional changes to the code.

  Minimal and efficient cross-platform file watching library

For watching files to new changes, we can make use of NodeJs inbuilt module, fs. It exposes a function called fs.watchFile but there have been a lot of issues reported by the community saying it’s not reliable. It fires multiple events sometimes for a single file change which results in high CPU utilization. So, to overcome this problem we can use the chokidar package.
