What are the differences between npm lockfiles?

There are two main lockfiles in npm: package-lock.json and npm-shrinkwrap.json. The package-lock.json file is automatically generated when you install packages and it locks the versions of the dependencies. On the other hand, npm-shrinkwrap.json is used to lock down the versions of dependencies for production environments, ensuring that the same versions are installed across different environments.

When should I use npm-shrinkwrap.json instead of package-lock.json?

You should use npm-shrinkwrap.json when you want to ensure that your application has the exact same dependency tree in production as it does in development. This is particularly important for applications that are deployed in multiple environments.

Can I use both lockfiles in the same project?

It's generally not recommended to use both lockfiles in the same project, as they can lead to confusion and inconsistencies. Stick to one based on your needs.

What happens if I delete my package-lock.json?

If you delete package-lock.json, npm will regenerate it the next time you run npm install. However, you may end up with different versions of dependencies than before, which could lead to unexpected behavior.
