NPM initialization

				
					npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help init` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

  2. Search between the packages. For example sillyname package.
  3. Copy the Install command on the top of right sidebar.
  4. Run the command in the command line of your project folder.

main.tsx

				
					npm i sillyname
				
			
				
					npm i sillyname

npm i sillyname

added 1 package, and audited 2 packages in 718ms

found 0 vulnerabilities

After successfully installation the package you will see a new section in your package.json file called “dependencies” and the name of the package (in this case: “sillyname”) inside it.

				
					{
  "name": "learning-npm",
  "version": "1.0.0",
  "description": "I'm learning about NPM",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Hoomaan",
  "license": "ISC",
  "dependencies": {
    "sillyname": "^0.1.0"
  }
}
				
			
				
					var generateName = require('sillyname');
var sillyName = generateName();

console.log(`My name is ${sillyName}.`);

ECMAScript

In case you want to use ECMAScript type, you need to update the package.json file and declare the type in it:

				
					{
  "name": "learning-npm",
  "version": "1.0.0",
  "description": "I'm learning about NPM",
  "main": "index.js",
  "type": "module",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Hoomaan",
  "license": "ISC",
  "dependencies": {
    "sillyname": "^0.1.0"
  }
}
				
			
				
					// var generateName = require('sillyname');
import generateName from 'sillyname';
var sillyName = generateName();

console.log(`My name is ${sillyName}.`);
