node.js - How to uninstall npm modules in node js?

As commonly known, any npm module can be installed by running a simple command: npm install .

I have installed a few modules that I do not use anymore and I just want to get them off. I have a few questions regarding this:

• Do we have any command or process to uninstall a module from the root (something like npm uninstall )
  or will simply removing the module files do?




• How does it affect us if we keep the unused modules?

Answer

The command is simply npm uninstall

The nodejs documents https://npmjs.org/doc/ have all the commands that you need to know with npm.

A local install will be in the node_modules/ directory of your application. This won't affect the application if a module remains there with no references to it.

If you're removing a global package however, any applications referencing it will crash.

Here are different options:

npm uninstall removes the module from node_modules, but not package.json

npm uninstall --save also removes it from dependencies in package.json

npm uninstall --save-dev also removes it from devDependencies in package.json

npm -g uninstall --save also removes it globally
