Yarn is a JavaScript package manager that facilitates the management of dependencies for Node.js projects. Designed as an alternative to npm (Node Package Manager), Yarn emphasizes speed, reliability, and security in handling project dependencies.

Key Features of Yarn:

  1. Parallel Installation:
    • Yarn installs packages in parallel, resulting in faster installation times compared to npm’s sequential process.
  2. Deterministic Dependency Resolution:
    • Yarn generates a yarn.lock file, ensuring that all developers in a project install the exact same package versions.
  3. Offline Mode:
    • Once a package is downloaded, Yarn caches it locally, enabling offline installations without needing to redownload packages.
  4. Enhanced Security:
    • Yarn performs checksum verifications to ensure the integrity and authenticity of downloaded packages.
  5. Workspace Support:
    • Yarn supports monorepos, enabling multiple packages to share dependencies and be managed within a single repository.
  6. Compatibility:
    • Fully compatible with npm’s package registry, allowing developers to install npm packages without issues.

Advantages of Using Yarn:

  • Speed: Faster dependency installations due to parallel execution.
  • Stability: The yarn.lock file ensures consistent dependencies across different environments.
  • Efficiency: Caching reduces the need for redundant downloads, saving bandwidth and time.
  • Security: Integrity checks prevent the installation of compromised or tampered packages.
  • Scalability: Workspace support makes Yarn ideal for large-scale projects involving multiple packages.

Applications:

  • Managing dependencies for small to large-scale Node.js projects.
  • Handling monorepo setups in enterprise-level applications.
  • Ensuring consistency and stability in collaborative development environments.

System Requirements:

  • Node.js: Yarn requires Node.js to operate. The recommended version depends on the Yarn version used.
  • Supported Operating Systems: Ubuntu, macOS, Windows, and other Unix-based systems.

Yarn is widely adopted in the development community for its performance and robust features, making it a valuable tool for managing JavaScript project dependencies efficiently.

Create an Instance

To get started, create a server instance running Ubuntu 24.04.

Access the Dashboard: Log in to your Shape.Host account and navigate to your Dashboard.
Click Create: Click on the “Create” button located in the top-right corner.
Select Instances: From the dropdown menu, choose “Instances” to begin creating a new cloud server.

Select Location: Choose a data center location for your instance closest to your target audience for optimal performance.

Shape.host instance form with the data center location selector highlighted.

Choose a Plan: Scroll through the available pricing plans. Select a plan based on your project requirements, such as Standard, CPU-Optimized, or Memory-Optimized.

Choose an Image: Select Ubuntu 24.04 as the operating system for your instance.

Shape.host instance form with the operating system image selector highlighted.

Authentication and Finalize: Choose your authentication method, either via SSH keys or password. Once done, click Create Instance to launch your server.

Connect to Your Instance

To connect to your instance:

  • Use an SSH client like Terminal (Linux/macOS) or PuTTY (Windows).
  • Run the following command to connect to your instance:
ssh root@<your_server_ip>

After connecting to your server, update your system packages and install Node.js along with npm by running:

apt update && apt upgrade -y  
apt install npm nodejs
Terminal showing APT package management commands and output.

Verify the installation by checking the versions of npm and Node.js using:

npm -v && nodejs -v
Terminal displaying Node.js and npm version numbers.

Next, install Yarn globally using npm. This is done by running the command:

npm install --global yarn
Terminal showing npm package installation messages.

Once installed, verify Yarn by checking its version:

yarn --version
Terminal showing yarn commands or output during Connect to Your Instance.

Alternatively, you can install Yarn using the official Yarn repository. Start by adding the Yarn GPG key with the following command:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | gpg --dearmor | tee /usr/share/keyrings/yarnpkg-archive-keyring.gpg > /dev/null

Add the Yarn repository by running:

echo "deb [signed-by=/usr/share/keyrings/yarnpkg-archive-keyring.gpg] https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
Terminal showing curl commands or output during Connect to Your Instance.

Then update your package list and install Yarn with:

apt update && apt install yarn
Terminal showing APT package management commands and output.

Verify the installation by checking the Yarn version again:

yarn --version

If you ever need to uninstall Yarn, you can remove the npm-installed version by using:

npm uninstall --global yarn
Terminal showing yarn commands or output during Connect to Your Instance.

To remove Yarn installed via the package manager, use:

apt purge yarn -y
Terminal showing APT package removal details.

Finally, confirm that Yarn has been uninstalled by running:

yarn --version
Terminal showing a Yarn version check that fails because the executable is missing.

You have now successfully installed Yarn on Ubuntu 24.04 using both npm and the official repository. For reliable hosting services tailored to JavaScript projects, consider using Shape.Host Linux SSD VPS.
