To begin, you must add the NodeSource repository to your Fedora system. This repository contains the latest versions of both Node.js and Yarn. Adding the repository ensures that your package manager knows and can fetch the available packages during installation.

To add the NodeSource repository, run the following command:

Current Release:

curl -sL https://rpm.nodesource.com/setup_current.x | sudo bash -

LTS Release:

curl -sL https://rpm.nodesource.com/setup_lts.x | sudo bash -

This command downloads and executes, adding the NodSource repository. Additionally, you will also need to import the following repository:

curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo

Step 2: Install Yarn via DNF Command

With the NodeSource repository added, you can now install Yarn using the dnf package manager. This command will fetch and install the latest Yarn version from the NodeSource repository, along with any required dependencies.

To install Yarn, execute the following command:

sudo dnf install yarn nodejs

After the installation is complete, you can verify the successful installation by checking the Yarn version:

yarn --version

The output should display the installed version number, confirming that Yarn is now installed on your Fedora system using the NodeSource RPM repository.

Install Yarn on Fedora Linux via NVM

Step 1: Install NVM on Fedora

First, you’ll need to install NVM on your Fedora system. NVM is a powerful tool that simplifies the process of installing and managing multiple Node.js versions.

To install NVM, use the official installation script by running the following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash

or

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash

This command downloads and executes the NVM installation script to set up NVM on your system.

After installing NVM, close and reopen your terminal, or run the following command to ensure NVM is sourced and available for use:

source ~/.bashrc

Step 2: Install Node.js and Yarn

With NVM installed, you can now install the desired version of Node.js. NVM allows you to install multiple versions and switch between them as needed.

To install the latest LTS (Long Term Support) version of Node.js, run:

nvm install --lts

Alternatively, to install the latest current version, run:

nvm install stable

Once you have installed the desired Node.js version, you can install Yarn globally for the selected version. This ensures that the Yarn installation is associated with the chosen Node.js environment.

To install Yarn globally, execute the following command:

npm install -g yarn

After the installation is complete, you can verify the successful installation by checking the Yarn version:

yarn --version

The output should display the installed version number, confirming that Yarn is now installed on your Fedora system using NVM.

Setting Up Yarn on Fedora Linux

In this section, we’ll guide you through setting up and configuring Yarn for optimal use on your Fedora system. The proper configuration ensures that Yarn is tailored to your specific development needs and workflows. We will cover the steps to configure Yarn, set up environment variables, and manage packages.

Step 1: Configuring Yarn

Yarn provides various configuration options that allow you to customize its behavior to suit your needs better. You can modify these settings using the yarn config command, followed by the setting you want to change.

For example, to set the global cache directory, you can use the following command:

yarn config set cache-folder /path/to/your/cache

This command sets the cache directory to the specified path, ensuring that Yarn stores its cache files in your desired location.

Another useful configuration option is the registry URL, which determines the package repository Yarn uses when fetching packages. By default, Yarn uses the npm registry. However, you can change this to use a different registry, such as a private repository or a mirror. To change the registry URL, run:

yarn config set registry https://registry.yarnpkg.com

This command sets the registry URL to the official Yarn registry. Replace the URL with the desired registry address as needed.

Step 2: Setting up Environment Variables

To ensure seamless integration of Yarn with your development environment and command-line tools, it’s essential to set up the appropriate environment variables.

For example, to add the global Yarn binary directory to your system’s PATH, edit your ~/.bashrc or ~/.bash_profile file and add the following line:

export PATH="$PATH:$(yarn global bin)"

This line ensures that globally installed Yarn packages are accessible from any directory in your terminal.

After adding the line, close and reopen your terminal or run the following command to source the updated configuration:

Step 3: Managing Packages

Yarn makes it easy to manage your project’s dependencies, allowing you to add, remove, and update packages as needed.

To add a package to your project, use the yarn add command:

yarn add package-name

For example, to add the lodash package, run:

yarn add lodash

To remove a package, use the yarn remove command:

yarn remove package-name

To update a package, use the yarn upgrade command:

yarn upgrade package-name

If you want to update all packages in your project to their latest versions, run:

yarn upgrade

These are just a few examples of how you can manage packages with Yarn.

Working with Yarn on Fedora Linux

In this section, we’ll delve deeper into using Yarn on Fedora Linux by exploring various tasks commonly performed in a development environment. We’ll cover creating new projects, managing dependencies, running scripts, and more. This information will help you effectively utilize Yarn to streamline your development process.

Creating a New Project

To create a new project with Yarn, navigate to the directory where you want the project to be located and run the yarn init command:

yarn init

This command will prompt you to enter information about your project, such as its name, version, description, and entry point. After providing the necessary information, Yarn will generate a package.json file in your project directory. This file serves as the manifest for your project and includes metadata, dependencies, and scripts.

Managing Project Dependencies

Yarn makes it simple to manage your project’s dependencies. You can add, update, and remove packages with ease.

Add a Yarn Package

To add a package as a dependency, use the yarn add command followed by the package name:

yarn add package-name

For instance, if you want to add the axios package for making HTTP requests, run:

yarn add axios

This command will add the package to your package.json file and install it in the node_modules directory.

Update Yarn Package

To update a specific package to its latest version, use the yarn upgrade command followed by the package name:

yarn upgrade package-name

For example, to update the axios package, run:

yarn upgrade axios

Remove Yarn Package

To remove a package from your project, use the yarn remove command followed by the package name:

yarn remove package-name

For instance, to remove the axios package, run:

yarn remove axios

Running Scripts

Yarn allows you to define custom scripts in your package.json file to automate repetitive tasks or simplify complex commands.

For example, you might have a script to start your development server:
