What is Yarn?
Yarn is a fast, reliable, and secure dependency management tool. It is primarily used in web development to manage and install project dependencies. Yarn is a project by Facebook, Google, Exponent and Tilde. It efficiently queues up requests and avoids request waterfalls to maximize network utilization.
Why is Yarn important in Web Development?
Yarn plays a significant role in web development due to its unique features that make it stand out from other package managers. These features include:
- Speed: Yarn caches every package it downloads, so it never needs to download the same package again. It also performs operations parallelly which increases performance speed.
- Security: Yarn uses checksums to verify the integrity of every installed package before its code is executed.
- Determinism: Yarn ensures the install that worked on one system will work exactly the same way on any other system.
How to install and use Yarn?
To install Yarn, you can use the following command:
npm install -g yarn
Once installed, you can use Yarn to add a package to your project with the command:
yarn add [package_name]
Yarn also allows you to upgrade packages, remove packages and update your project dependencies to their latest version.
Yarn is a powerful tool for managing project dependencies. It ensures fast, secure, and reliable web development. Understanding its usage can help website designers, developers, and administrators to streamline the development process and build efficient web applications.
