nodemon is a development tool that automatically restarts Node.js applications when file changes are detected.
The tool solves the friction of manual server restarts during development. It works by wrapping the standard node command and monitoring the project directory for changes, then automatically restarting the application when modifications are detected. The approach requires no changes to application code or development workflow—developers simply replace `node` with `nodemon` on the command line. nodemon handles both applications that hang indefinitely and those that exit cleanly, continuing to monitor and restart as needed. It also supports manual restarts via the `rs` command without stopping the tool itself.
Developers should adopt nodemon for any Node.js project where rapid iteration matters. It suits local development environments where automatic restarts eliminate context-switching overhead. The tool works as both a global installation and a local development dependency installable through npm. Configuration is optional but supported through `nodemon.json` files in the current directory or home directory, with command-line arguments taking precedence. The tool can read the main entry point from `package.json` automatically, and supports passing through all standard node arguments including the inspect flag for debugging.
Development activity shows consistent maintenance with regular engagement on issues and pull requests. The project maintains comprehensive documentation including a FAQ section and handles feature requests and bug reports actively. Updates are released to address user-reported problems and extend compatibility with different file types and runtime configurations.
