Many developers need to share their projects with other communities around the world. To do that, they must pack their projects into compact formats and start sharing them. Yarn is one of the most widely used and popular dependency managers developers use for making compact formats and sharing them. Yarn is popular because of its robust security, consistency, and high speed. This yarn was created as a solution to the problems and issues of its competitor, the Node package manager (npm).
As Yarn is known as a very useful manager for many developers, we explain how to install it on different operating systems using different tools.
What Is Yarn?
For years, the npm client worked flawlessly at Facebook. However, as the size of their codebase and the number of engineers grew, they ran into consistency, security, and performance issues. Unable to solve each issue independently, they created a new solution designed to help manage dependencies more reliably. This updated product is called Yarn — a fast, reliable, and secure alternative to npm.
Yarn is a package manager for Node.js developed by engineers. It eliminates engineers' concerns about managing dependencies across machines or in an offline environment by using the npm registry. Furthermore, Yarn allows engineers to deploy code faster and more confidently thanks to shared code.
Features of Yarn
Before discussing how to install Yarn, let's look at its features. We mentioned four features below:
- High speed for application setup: Per-project caching makes Yarn faster for installing an application. Data from every package installation will be stored in Yarn's cache, making the setup process faster.
- Users can extend the functionality: The pre-installed plugins that come with Yarn make it useful. With these plugins, users can extend the functionality by installing more add-ons.
- Check the integrity of all packages: To ensure the integrity of all packages, Yarn checks them regularly before the setup process.
- Manage the dependencies of multiple projects: Yarn offers workspaces that provide a single repository to manage the dependencies of multiple projects.

After adding the repository, run the following command and press “Enter” to update the package list:
sudo apt update
Now, use the below command to install Yarn:
sudo apt install yarn
You may want to check whether the installation process was successful or not. Run the following command and press “Enter” to be sure of this:
Using cURL to install Yarn on CentOS
To install Yarn using cURL on CentOS, follow the steps below:
Open “Terminal” on your CentOS system and log in via SSH.
For adding the Yarn repository, type the following command in “Terminal”:
$ curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
Now, run the following command in “Terminal” and press “Enter” to import the repository’s GPG key:
sudo rpm --import https://dl.yarnpkg.com/rpm/pubkey.gpg
Next, you need to install Yarn by running the command below and pressing the “Enter” key:
