Node Mon Install - Javascript

If you are a Javascript developer, then you must have heard about Node.js - a Javascript runtime built on Chrome's V8 JavaScript engine. Node.js allows you to run Javascript on the server-side, providing an efficient, scalable, and lightweight platform with a massive ecosystem of libraries and frameworks.

However, developing Node.js applications requires a lot of repetitive tasks, such as restarting the server every time you make a change in the code. This is where nodemon comes in handy.

Nodemon is a utility that monitors your Node.js application for any changes and automatically restarts the server, saving you time and effort. In this tutorial, we will learn how to install nodemon and use it to build fast and efficient Node.js applications.

Prerequisites

Before we start, you need to have Node.js installed on your system. You can check if Node.js is installed by running the following command in your terminal/command prompt:

node --version

Step 1 — Installing Nodemon

To install nodemon, open your terminal/command prompt and run the following command:

npm install -g nodemon

This command installs nodemon globally (-g) on your system, so you can use it across multiple projects.

Step 2 — Using Nodemon

To use nodemon, navigate to your Node.js project directory in your terminal/command prompt and run the following command:

nodemon <your-entry-file>.js

Replace <your-entry-file>.js with the name of your Node.js entry file, such as app.js or server.js.

Now, nodemon will monitor your application for any changes and restart the server automatically. You can test it by making a change in your code and observing the console output.

Conclusion

In this tutorial, we learned how to install nodemon and use it to build fast and efficient Node.js applications. Nodemon is a useful tool that saves time and effort by automatically restarting the server whenever you make a change in your code. With these skills, you can now streamline your Node.js development process and focus on writing great code.
