npm Cache

When developing with npm, you may notice that if you delete the node_modules folder and then reinstall dependencies, the installation is very fast. This is because npm has a caching mechanism.

What is npm Cache

npm cache is a mechanism where npm downloads dependency packages to a local cache directory during installation. The next time you install, if the dependency package already exists in the cache directory, npm retrieves it directly from the cache instead of downloading it again.

How to View npm Cache
