As commonly known, any npm module can be installed by running a simple command: npm install <module_name>.
I have installed a few modules that I do not use any more 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 <module_name>)
or will simply removing the module files do? -
How does it affect us if we keep the unused modules?
Answers:
The command is simply npm uninstall <name>
The Node.js 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 <name> removes the module from node_modules but does not update package.json
npm uninstall <name> --save also removes it from dependenciesin package.json
npm uninstall <name> --save-dev also removes it from devDependencies in package.json
npm uninstall -g <name> --save also removes it globally
