Right way uninstalling the NPM packages (Npm Uninstall vs Edit package.json)

Question

I have to remove several libraries from the project. Currently worried about what if I remove a library, which is dependency of any other library.

Which approach can safely remove the libraries ?

I see I have two choices:

1. Edit package.json manually. Remove library entries... Delete node_modules folder and do npm install.

2. do npm uninstall --save for each package.

What are difference between two, especially when I want to take one step at a time. Without breaking any peer dependencies

Answer 1

There is no difference at all

npm un package_name package_name ....

will uninstalls a package, completely removing everything npm installed on its behalf

It also removes the package from the dependencies, devDependencies, optionalDependencies, and peerDependencies objects in your package.json and update package-lock.json file also

--save or -S will tell npm to remove the package from your package.json and package-lock.json files. This is the default, you don't have to use it.

--no-save is opposite to --save will tell npm not to remove but uninstall
