This tutorial will guide you through the installation of Yarn on CentOS 8. We will also cover the basics of how to use Yarn to create a new project and add/remove dependencies.
Installing Yarn on CentOS 8
Perform the following steps as root or user with sudo privileges to install Yarn on CentOS 8:
If Node.js is not installed on your system, install the Node.js package by typing:
sudo dnf install @nodejs
At the time of writing, the Node.js version in the Centos8 repositories is v10.x.
Enable the Yarn repository and import the repository’s GPG key:
curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo

Now that you have Yarn installed on your CentOS system, we’ll explore some of the most common Yarn commands.
Creating a new project

To upgrade the packages, use one of the following commands:

yarn upgrade [package_name]@[version_or_tag]
If no package name is given, the command will update the project dependencies to their latest version according to the version range specified in the package.json file. Otherwise, only the specified packages are updated.
