How To Install Nodemon In Node Js
Nodemon is a utility that helps in automatically restarting your Node.js application when any changes are detected in the code. This eliminates the need for manually stopping and restarting the server every time you make a code change, making the development process more efficient and productive. To install nodemon, you can use npm with the command ‘npm install -g nodemon’ to install it globally on your system. After installation, you can use the ‘nodemon’ command in place of ‘node’ to run your application, and it will automatically restart whenever you make changes, saving you time and effort during the development process.

1 - Nodemon is a utility that helps monitor changes in your Node.js application and automatically restart the server when changes are detected. It is a useful tool for developers as it saves time and effort during the development process.
2) To install Nodemon, you need to have Node.js installed on your system. If you haven't already installed Node.js, you can download it from the official website and follow the installation instructions.
3) Once you have Node.js installed, you can install Nodemon globally by running the following command in your terminal:
```
npm install g nodemon
```
4) The ` g` flag is used to install Nodemon globally so that you can access it from any directory in your system.
5) After the installation is complete, you can use Nodemon by running your Node.js application with the following command:
```
nodemon your app.js
```
6) Replace `your app.js` with the main file of your Node.js application.
7) Nodemon will start monitoring your files for changes and automatically restart the server whenever you save a file.
8) You can also customize Nodemon behavior by adding a nodemon.json or nodemon.config.js file in your project directory. This allows you to specify options such as ignoring specific files or directories.
9) Another way to use Nodemon is by adding it as a development dependency in your project's package.json file. This way, you can use Nodemon without installing it globally on your system.
10) To add Nodemon as a development dependency, run the following command in your project directory:
```
npm install save dev nodemon
```
11) Once Nodemon is added as a development dependency, you can update your package.json file to include a script for running Nodemon. For example:
```
“scripts”: {
“dev”: “nodemon your app.js”
}
```
12) Now you can start your Node.js application using Nodemon by running:
```
npm run dev
```
13) This will start your application with Nodemon, allowing you to benefit from automatic server restarts during development.
14) As part of our training program for students, we will cover the installation and usage of Nodemon to help them streamline their Node.js development process.
15) By mastering Nodemon, students will be able to efficiently work on their Node.js projects without the need to manually restart the server every time a change is made, increasing their productivity and facilitating a smoother development experience.
