How to Install Yarn on Debian 10

Introduction

Before we start talking on how to install Yarn on Debian 10, let's briefly understand - What is Yarn?

Yarn, which stands for Yet Another Resource Negotiator, is a package manager that was first proposed by Facebook to address npm's inadequacies.

Yarn is a package manager for Node.js that provides a fast and reliable installation process. It is designed to optimize package fetching and supports parallel installations, making it popular among developers.

In this tutorial, you will install Yarn on Debian 10. We will also address a few FAQs on how to install Yarn on Debian 10.

Advantages of Yarn

1. Fast and Parallel Installations: Yarn optimizes package installations for improved performance by utilizing parallel execution and caching.
2. Reliable Dependency Resolution: Yarn ensures consistent and deterministic dependency resolution, providing reliable installations across different environments.
3. Offline Mode Support: Yarn offers offline mode, allowing developers to work in disconnected environments without compromising package installations.
4. Automatic Lock File Management: Yarn automatically creates and updates a lock file (yarn.lock) to prevent dependency conflicts and ensure consistent installations.
5. Large Ecosystem and Community: Yarn benefits from a large ecosystem of packages and an active community that contributes to its development, ensuring ongoing improvements and support.

Distinctive Qualities of yarn

The following list of distinctive qualities of the yarn package manager is provided:

• Speed: Yarn uses a parallel installation strategy, which speeds up and improves the performance of the package by installing packages parallelly. While npm will finish installing one package before going on to the next, performance latency is experienced in this circumstance.
• Security: Yarn uses a cryptographic hashing mechanism to make sure that packages are installed securely.
• Log: The majority of package managers strive to deliver a readable output, however, their output interfaces vary. Yarn does support producing output that is clear and readable.
• Information about dependencies: Yarn, which was created to address npm's deficiencies, supports the "why" command, which explains the rationale for any dependency's existence.
• Lock file: To assist in maintaining the project dependencies, yarn creates "yarn.lock" files each time a module is introduced.
