nodemon

Nodemon is a command line tool used for automatically restarting Node.js applications. It eliminates the need to manually restart the server every time a change is made to the code. Nodemon watches the files in the specified directory and restarts the server as soon as any changes are detected.

It is commonly used during development to streamline the development process and improve productivity. Nodemon is particularly helpful when working on large applications or complex codebases, as it saves time by avoiding the manual server restart.

Nodemon is simple to install globally via npm and can be easily incorporated into any Node.js project. It supports various command line options to customize its behavior, such as specifying the file extensions to monitor, ignoring specific file paths, or setting environment variables.

With nodemon, developers can focus on writing code without constant interruptions for server restarts. It offers a seamless development experience by automatically refreshing the server and displaying detailed information about the restart process, including the reason for the restart and any errors encountered.

Additionally, nodemon allows developers to specify custom actions or scripts to execute on each restart, such as running test suites or synchronizing data.

Nodemon enhances the development workflow by rapidly reflecting code changes and providing instant feedback, making it a valuable tool for Node.js developers. It significantly speeds up the development iteration cycle, enabling faster debugging and testing of applications.
