What are the differences between Bower and npm?

What is npm?

Node Package Manager (npm) is a package manager and dependency management tool for the Node.js runtime environment. It allows developers to easily manage and share reusable modules used in Node.js applications. These packages can contain various types of code, including libraries, frameworks, tools, and associated metadata and configuration files. Let’s test npm by using the terminal below to run the following command:
npm install jquery

Terminal 1
Terminal
Loading...

What is Bower?

Bower is a package manager for managing frontend dependencies in web development projects. It allowed developers to easily install and manage libraries, frameworks, CSS files, fonts, and other assets required for building web applications. Bower aims to simplify fetching and integrating external resources into projects.

What is the difference between Bower and npm

While both are used in the web-dev ecosystem for management and distribution, the two have some key differences. The differences are outlined in the table below:

Metric

Bower

npm

Scope

Designed for managing frontend dependencies such as CSS and JS.

Primarily used for managing Node.js packages, including server-side and front-end packages. It is more versatile and can handle various packages, including those used in server-side development.

Dependency resolution

Bower uses a flat dependency structure, and as such, all the dependencies are installed in the same file

npm uses a nested dependency structure, allowing different packages to have their own specific dependencies. It creates a node_modules folder for each package, which can lead to more efficient and isolated dependency management.

Popularity

Bower was once a popular framework, but that is no longer the case due to the rise of more powerful tools like npm, yarn, etc.

npm is one of the most widely used package managers in the JavaScript ecosystem and continues to be actively maintained and developed.
