description nodemon Overview

Nodemon is an open-source command-line tool designed for Node.js development. It monitors source files and automatically restarts the server whenever a change is detected. This significantly reduces developer time spent manually restarting applications during development cycles. It’s particularly useful for JavaScript developers working with Node.js environments.

help nodemon FAQ

How do I install nodemon globally using npm?

You can install nodemon globally on your system by running the command `npm install -g nodemon` in your terminal. Once installed globally, you can run it from any local project directory by simply typing `nodemon` followed by the name of your Node.js entry file.

How do I add a delay before nodemon restarts my Node.js app?

If you are working with compilers or tools that take a moment to save files, you can add a delay by using the `--delay` flag followed by a number of seconds. For example, running `nodemon --delay 2.5 server.js` will force nodemon to wait exactly 2.5 seconds after the last file change before restarting the application.

How do I ignore specific directories in nodemon?

To prevent nodemon from endlessly restarting when non-critical files change, use the `--ignore` flag followed by the directory path. For instance, running `nodemon --ignore public/` ensures that changes to static assets in the public folder won't trigger a Node server restart.

Can I use nodemon to watch and restart a TypeScript application?

Yes, you can configure nodemon to monitor TypeScript files by modifying your `nodemon.json` file to execute `ts-node` instead of standard node. This setup allows developers to automatically compile and run `.ts` files directly in real-time without manually running `tsc` first.
