Mastering Yarn: Installation and Usage Guide on Ubuntu

How to Install Yarn on Ubuntu

If you are a web developer, then you know the importance of package managers. They make your life easier by enabling you to manage project dependencies and share code across multiple projects.

Yarn is one of the popular package managers in the JavaScript ecosystem. This tool comes with many features like caching, offline mode, and parallel execution, which make it faster and more reliable than other package managers.

Here is how you can install it on Ubuntu.

Enabling the Yarn Repository

Before installing Yarn, you need to enable the Yarn repository and add the corresponding GPG key to your system. The GPG key verifies the authenticity of the packages you download.

Open the terminal and run the following command:

“`

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add –

“`

This command downloads the GPG key and adds it to your system’s keyring. You can verify that the key is added by running the following command:

“`

sudo apt-key list

“`

This command lists all the keys in your system’s keyring. Look for the key with the fingerprint `072A 3297 2A3C 1739 2C27 F73D 0E61 6D29 F77F 0EA4`, which is the Yarn repository key.

Adding the Yarn APT Repository

After adding the GPG key, you need to add the Yarn APT repository to your system’s software sources. This repository contains the Yarn packages that you can install using the apt-get command.

Run the following command to add the repository:

“`

echo “deb https://dl.yarnpkg.com/debian/ stable main” | sudo tee /etc/apt/sources.list.d/yarn.list

“`

This command adds a new file `/etc/apt/sources.list.d/yarn.list` with the repository URL.

Installing Yarn

Now that you have set up the repository, you can install Yarn by running the following command:

“`

sudo apt-get update && sudo apt-get install yarn

“`

This command updates your system’s package list and installs the latest version of Yarn. You can confirm that Yarn is installed by running the following command:

“`

yarn –version

“`

This command displays the current version of Yarn.

Verifying Yarn Installation

If you see the version number of Yarn after running the above command, congratulations! You have successfully installed Yarn on your Ubuntu system. You are now ready to use it for your projects.

How to Use Yarn

Creating a New Project

To create a new project with Yarn, navigate to your project directory and run the following command:

“`

yarn init

“`

This command initializes a new Yarn project and creates a file named `package.json`. This file contains metadata about your project, including its name, version, description, and dependencies.

Adding a Dependency

To add a dependency to your project, run the following command:

“`

yarn add

“`

Replace `` with the name of the package you want to install. Yarn will download the package and add it to your `package.json` file.

Upgrading a Dependency

To upgrade a dependency to its latest version, run the following command:

“`

yarn upgrade

“`

Replace `` with the name of the package you want to upgrade. Yarn will download the latest version and update your `package.json` file with the new version number.

Removing a Dependency

To remove a dependency from your project, run the following command:

“`

yarn remove

“`

Replace `` with the name of the package you want to remove. Yarn will remove the package from your `package.json` file and delete its files from your `node_modules` directory.

Installing All Project Dependencies

To install all the dependencies listed in your `package.json` file, run the following command:

“`

yarn install

“`

Yarn will download and install all the required packages and their dependencies.
