NPM Tutorial for Beginners - 6 - Installing Local Packages (English)

Installing a Package:
To install a package locally (meaning it's installed in your project's node_modules directory), run the following command in your project's root directory:

sh
Copy code
npm install package-name
Replace package-name with the name of the npm package you want to install. For example, to install the Express framework:

sh
Copy code
npm install express
Installing a Package and Saving it as Dependency:

sh
Copy code
npm install package-name --save

sh
Copy code
npm install express --save
Installing a Package as a DevDependency:

sh
Copy code
npm install package-name --save-dev
For example, to install Nodemon as a devDependency:

sh
Copy code
npm install nodemon --save-dev
Installing a Global Package:
Some npm packages are designed to be used globally, meaning they are installed once on your system and can be accessed from any directory. To install a package globally, use the -g flag:

sh
Copy code
npm install -g package-name
For example, to install the TypeScript compiler globally:

sh
Copy code
npm install -g typescript
