Nodemon

Nodemon is a tool that allows developers to automatically restart Node.js applications whenever they make changes to the codebase. This means that developers can focus on writing code without needing to manually restart their applications every time they make a change.

Installation

To get started with Nodemon, you'll first need to install it globally:

npm install -g nodemon

Usage

Once you have nodemon installed, you can use it by simply running nodemon followed by the name of the file you want to run:

nodemon app.js

This will restart your Node.js application whenever you make changes to any of the files in your codebase.

You can also pass additional command line arguments to Nodemon, such as the --watch flag to specify which files and directories to watch:

nodemon --watch lib/ app.js

This will restart your application any time a file in the lib/ directory or any of its subdirectories is changed.

Benefits

The main benefit of using Nodemon is that it can save developers a lot of time and frustration by automatically restarting their application whenever they make changes to the codebase. This means that developers can stay focused on writing code rather than worrying about having to repeatedly restart their application.

Additionally, Nodemon can be particularly useful during development, when developers are regularly making changes to their codebase. By automatically restarting the application whenever changes are made, developers can be confident that their changes are being tested and deployed correctly.

Conclusion

Overall, Nodemon is a powerful and useful tool for developers who work with Node.js. It can help save time and reduce frustration by automatically restarting applications whenever changes are made to the codebase. Whether you're a seasoned developer or just starting out, Nodemon is definitely worth checking out.
