Testing npm Packages Locally with npm pack

Today I learned about the npm pack command, which creates a package archive and allows you to test the package without publishing it. It creates a .tgz file similar to the one sent to the registry when you run npm publish.

This helped me test the package by installing it in my frontend application and checking whether it breaks anything.

To install it locally, I had to provide the path to the generated package file during installation:

npm install ../path-to-the-file/package.tgz
