Christian WellsYarn is a modern, open-source JavaScript package manager designed for speed, efficiency, and security. Developed by Meta (formerly Facebook), Yarn is an alternative to npm (Node Package Manager) and offers enhanced dependency management, better caching, and parallel installations. Running Yarn on Debian 12 provides a stable, secure, and high-performance environment for JavaScript and Node.js development.
Key Features of Yarn on Debian 12
- Faster Package Installation
- Utilizes parallel execution and a global cache to speed up installations.
- Deterministic Dependency Resolution
- Uses lock files (
yarn.lock) to ensure consistent package versions across environments.
- Uses lock files (
- Offline Mode
- Installs dependencies from a local cache, reducing reliance on network connections.
- Improved Security
- Checksum verification ensures that installed packages have not been tampered with.
- Workspaces for Monorepos
- Supports monorepos, enabling efficient dependency management across multiple projects.
- Selective Dependency Resolution
- Allows installing specific packages without modifying the entire dependency tree.
- Plug’n’Play (PnP) Mode
- Eliminates
node_modules, improving performance and simplifying project structure.
- Eliminates
- Cross-Platform Compatibility
- Works seamlessly on Debian 12, as well as Windows, macOS, and other Linux distributions.
- Compatibility with npm
- Supports npm registry and package format, allowing easy migration from npm to Yarn.
- Better Script Execution
- Run project scripts efficiently using
yarn run, with improved logging and performance.

Step 1: Set Up a Server Instance
Before installing Yarn, you need a Debian 12 server. Follow these steps to create one:
Access Shape.Host Dashboard: Log into your Shape.Host account and navigate to the Dashboard.
Create a New Instance: Click the “Create” button in the top-right corner.
Select Server Type: Choose “Instances” to begin configuring your server.
Choose a Data Center Location: Select a data center close to your users for optimal performance.
Pick a Hosting Plan: Choose a plan that meets your project requirements, whether Standard or CPU-Optimized.
Set Up the Operating System: Select Debian 12 as the server’s OS.
Finalize and Deploy: Choose your authentication method (SSH keys or password) and click Create Instance.
Find the Instance IP: Retrieve the public IP address of your instance from the Shape.Host dashboard.
Step 2: Connect to Your Server
Connect to your server using SSH:
- Linux/macOS:
ssh root@<your_server_ip> - Windows: Use PuTTY, enter your server’s IP, and log in with your credentials.
Step 3: Update System and Install Node.js
Step 3.1: Update and Upgrade Packages
Ensure that all system packages are up to date:
apt update && apt upgrade -y
Step 3.2: Install Node.js and npm
Yarn requires Node.js and npm to function properly. Install them using:
apt install npm nodejs gpg
Step 3.3: Verify Node.js and npm Installation
Check the installed versions:
npm -v && nodejs -v
If both commands return version numbers, Node.js and npm are installed correctly.
Step 4: Install Yarn
Step 4.1: Install Yarn Using npm
Run the following command to install Yarn globally:
npm install --global yarn
Step 4.2: Verify Yarn Installation
Confirm that Yarn is installed by checking its version:
yarn --version
The output should display the installed Yarn version, indicating a successful installation.
Step 5: Uninstall Yarn (Optional)
If you need to remove Yarn from your system, follow these steps:
Step 5.1: Uninstall Yarn via npm
npm uninstall --global yarn
Step 5.2: Remove Yarn Completely
To remove Yarn from the system, purge the package:
apt purge yarn -y
Step 5.3: Confirm Removal
Check if Yarn is still installed:
yarn --version
If Yarn is successfully removed, this command should return an error stating that Yarn is not found.
