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?
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
npm -g ls | grep -v 'npm@' | awk '/@/ {print $2}' | awk -F@ '{print $1}' | xargs npm -g rm to uninstall all gobally installed module. if you are on windows then you need to install Cygwin or git to run it
npm uninstall <name> now removes the module from both package.json` and node_modules
npm uninstall <name>

--save flag is no longer useful as it is the default behavior without the flag; if you want the old default behavior (leaving package.json untouched), use the --no-save flag. docs.npmjs.com/cli/install
If it doesn't work with npm uninstall <module_name> try it globally by typing -g.
Maybe you just need to do it as an superUser/administrator with sudo npm uninstall <module_name>.
Well, to give a complete answer to this question, there are two methods (for example we call the installed module as module1):
To remove module1 without changing package.json:
npm uninstall module1
To remove module1 with changing package.json, and removing it from the dependencies in package.json:
npm uninstall --save module1
Note: to simplify the above mentioned commands, you can use -S instead of --save , and can use remove, rm, r, un, unlink instead of uninstall
npm uninstall ... from the correct directory as well!

I just install stylus by default under my home dir, so I just use npm uninstall stylus to detach it, or you can try npm rm <package_name> out.
To uninstall the Node.js module:
npm uninstall <module_name>
This will remove the module from folder node_modules, but not from file package.json. So when we do npm install again it will download the module.
So to remove the module from file package.json, use:
npm uninstall <module_name> --save
This also deletes the dependency from file package.json.
And if you want to uninstall any globally module you can use:
npm -g uninstall <module_name> --save
This will delete the dependency globally.
To remove packages in folder node_modules in bulk, you could also remove them from file package.json, save it, and then run npm prune in the terminal.
This will remove those packages, which exist in the file system, but are not used/declared in file package.json.
P.S.: This is particularly useful on Windows, as you may often encounter problems with being unable to delete some files due to the "exceeded path length limit".
Sometimes npm uninstall -g packageName doesn’t work.
In this case you can delete package manually.
On Mac, go to folder /usr/local/lib/node_modules and delete the folder with the package you want. That's it. Check your list of globally installed packages with this command:
npm list -g --depth=0
Update for npm 5:
As of npm 5.0.0, installed/uninstalled modules are added/removed as a dependency by default, so the --save option is no longer needed.
Run
npm uninstall <package>
For example:
npm uninstall mongodb
It will remove the module from the node_modules folder and also the package.json file.
Alias can be used to to uninstall node_modules package
un alias for uninstall
- npm un <PACKAGE_NAME>
- npm un <PACKAGE_NAME_1> <PACKAGE_NAME_2>
node_modules packages - rm -rf node_modules/
rm -rf ... command for Linux or Unix? I'm on Windows, it won't seem to work for me, I get an error A parameter cannot be found that matches parameter name 'rf'

You can also run the following as shorthand:
npm un packageName or npm rm packageName
Note: Add -g at end of command to uninstall global packages.
Simply,
npm un module_name
OR
npm uninstall module_name
Make sure you uninstall it in the same directory as the package.json and node_modules folder.
I found this out the hard way, even if it is seemingly obvious.
I initially tried to loop through the node_modules directory running npm uninstall module-name with a simple for loop in a script. I found out it will not work if you call the full path, e.g.,
npm uninstall module-name
was working, but
npm uninstall /full/path/to/node_modules/module-name
was not working.
For Windows users - if you want to remove all the Node.js modules installed at once:
cd node_modules)It will uninstall all the modules.
To uninstall a module using npm, you can use:
npm uninstall moduleName
Also, if you want to uninstall and want the change to be reflected in your package.json then you can use the --save flag, like this:
npm uninstall moduleName --save
OR
npm uninstall -S
And if you want to uninstall a module from devDependencies and want the change to be reflected in package.json then you can use -D flag, like this:
npm uninstall moduleName -D
# Log in as root (might be required depending on install)
su -
# List all global packages
npm ls -g --depth=0
# List all local (project) packages
npm ls -p --depth=0
# Remove all global packages
npm ls -g --depth=0 | awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}' | xargs npm -g rm
# Remove all local packges
npm ls -p --depth=0 | awk -F/ '/node_modules/ && !/\/npm$/ {print $NF}' | xargs npm -p rm
# NOTE (optional): to use node with sudo you can add the bins to /usr/bin
# NOTE $PATHTONODEINSTALL is where node is installed (e.g. /usr/local/node)
sudo ln -s $PATHTONODEINSTALL/bin/node /usr/bin/node
sudo ln -s $PATHTONODEINSTALL/bin/npm /usr/bin/npm
The uninstall option didn't work for me when I tried to use the same command to the one I used in installing (as I was installing with the @latest directive)
So for example, I installed a package like this:
npm install @ngtools/webpack@latest
And then I wanted to uninstall it, so I used the same command (including @latest):
npm uninstall @ngtools/webpack@latest
So the above uninstall didn't work. I have to remove the @latest, and then it worked well:
npm uninstall @ngtools/webpack
In npm v6+ npm uninstall <package_name> removes it both in folder node_modules and file package.json.
Additionally, if you've started using yarn, in place of npm:
yarn remove <package-name>
Is the equivalent of:
npm uninstall <package-name> --save
This will
- remove the package from package.json, as well as
- uninstall it from your project's node-modules folder
The simplest solution is:
npm uninstall packageName --save-dev
See upper level packages names in the your project:
npm list --depth=0
The output will be like:
[email protected] /home/jackkobec/projects/myAppName
├── packageName@packageVersion
├── [email protected]
Copy package name and execute npm uninstall command. Example for express package:
npm uninstall express --save-dev
If you want to uninstall an specific package using npm, you can use the following command :
Sintax:
npm uninstall <package-name>
Example:
npm uninstall moment
If you want to uninstall a number of modules, then just run the npm uninstall.
Then go to file package.json and delete the unwanted module from there, and then just run the command npm install. It should fix your problem.
In case you are on Windows, run CMD as administrator and type:
npm -g uninstall <package name>
You can delete a Node.js module manually. For Windows,
Go to the node_modules directory of your repository.
Delete the Node.js module you don't want.
Don't forget to remove the reference to the module in your package.json file! Your project may still run with the reference, but you may get an error. You also don't want to leave unused references in your package.json file that can cause confusion later.
npm uninstall vercel -g
Will do the uninstallation globally
