npm install and adding to dependencies - Shell-Bash

As a programmer, managing dependencies is an important part of software development. One popular tool for managing dependencies in Node.js projects is npm. In this article, we will go over how to use npm to install packages and add them to your project's dependencies.

Installing packages with npm

To install a package with npm, simply run the following command:

npm install package-name

This will download the package and save it to your project's node_modules directory. If you want to save the package as a dependency of your project, use the --save flag:

npm install package-name --save

This will add the package to your project's dependencies section in the package.json file.

Adding packages to dependencies in package.json

If you want to manually add a package to your project's dependencies section in the package.json file, run the following command:

npm install package-name --save

This will add the package to your project's dependencies section in the package.json file with its version number.

Conclusion

In summary, using npm to manage dependencies in your Node.js projects is a simple and effective way to ensure that your code works as expected. By installing packages with npm and adding them to your project's dependencies section, you can easily manage your project's dependencies and ensure that they are always up-to-date.
