This article aims to compare Yarn and npm and determine the better choice for developers in 2023. We will be taking a closer look at the features and capabilities of both package managers and how they compare in terms of speed, security, and reliability.

By the end of this article, you should better understand the differences between Yarn and npm and be able to make an informed decision about which one is the right choice for your project.

What is Yarn?

Yarn is a package manager for JavaScript. It was released in 2016 by Facebook and is now maintained by a large open-source community. Yarn is a popular alternative to npm and is known for its faster installation speed and more efficient management of packages.

Yarn uses a lockfile to ensure consistency across different installations and to prevent the accidental use of outdated packages. It also can cache packages, making installing packages on subsequent installations faster.

Yarn also has features that make it more user-friendly than npm, such as running multiple scripts in parallel, better error messages, and a more intuitive command-line interface.

Additionally, Yarn has a broader range of compatibility with different operating systems, making it a popular choice for developers working on other platforms.

What is npm?

npm (short for Node Package Manager) is a package manager for the JavaScript programming language. It was created in 2010 as a way to manage the packages used in Node.js but has since become a widely used package manager for front-end JavaScript as well. npm is bundled with Node.js and can be easily installed on any system that supports Node.js. npm is open-source and has a vast repository of over 500,000 packages, making it the largest repository of JavaScript packages. npm allows developers to easily find and install packages, manage their dependencies, and share their packages with others. With npm, developers can easily add functionality to their projects by installing packages and easily manage multiple versions of packages and their dependencies.

Yarn vs npm

Comparison of Key Features

Yarn vs npm Package Management: 

Yarn and npm use a package.json file to manage a project’s dependencies. However, Yarn offers a more efficient and deterministic way of operating packages by using a lock file (yarn.lock) to keep track of the exact versions installed.

Yarn vs npm Speed: 

Yarn is known for being faster than npm in terms of package installation and overall performance. This is because Yarn uses a caching mechanism to store packages on the local disk, which speeds up the installation process.

Yarn Workspaces: 

Yarn Workspaces is a feature that allows developers to work with multiple packages in a single repository. This feature is handy for monorepos, where a large codebase is split into smaller packages for easier management.

Differences in Package Installation Process

Yarn uses the command yarn add to install packages, while npm uses npm install.

When using Yarn, a yarn.lock file is automatically created to keep track of the exact versions of packages installed, ensuring a consistent experience across different machines and installations. On the other hand, npm uses the package-lock.json file for the same purpose.

Yarn vs npm Comparison of Performance

In terms of performance, Yarn is known to be faster than npm in various tasks such as installing packages, checking for updates, and resolving dependencies.

This performance advantage can be attributed to Yarn’s use of a caching mechanism, which speeds up the installation process by downloading packages from the local cache rather than from the internet.

However, it is essential to note that the performance difference between the two package managers may vary depending on the size and complexity of the project.
