How to Clear Cache in Yarn?

Yet Another Resource Negotiator popularly known as Yarn, is an open-source package manager used for managing dependencies in Node.js projects. It was created by Facebook as a solution to security and performance concerns that arose with the use of npm (Node Package Manager), which was the dominant package manager at the time. Yarn offers a faster and more secure alternative to npm, making it a popular choice among developers. With Yarn, developers can easily manage and organize their project dependencies, allowing for a smoother and more efficient development process.

When using the “yarn install” command to install node packages, Yarn creates a cached copy of the package in the “~/.cache/yarn” directory. This helps to ensure a faster and more reliable installation process, as Yarn can access the cached package instead of downloading it from the internet again if needed.

To determine the path to your Yarn cache directory in your system, you can use the “yarn cache dir” command. This will display the location of the cache directory, where Yarn stores cached copies of packages for faster and more reliable installations.

Yarn optimizes the installation process of dependencies in a project by utilizing its cache files. Instead of downloading packages from the internet, Yarn directly installs them from the cache directory located in the system. This results in a faster and more efficient installation process, as well as a reduction in internet usage.

However, since package managers don’t automatically delete cached files, the yarn cache accumulates unused data, taking up significant space in our local storage.

It’s recommended to periodically clean the yarn cache folder to prevent errors during package installations.
