Uninstalling a package is about as easy installing.

## Process ##

<file txt uninstall locally>
 npm uninstall http-server
</file>

or

<file txt uninstall globally>
 npm uninstall http-server -g
</file>

### Delete All Local Packages
If you want to uninstall *all* packages, use [[IT/AD/Powershell/]], place yourself in the *local root directory* and do the following:

<file powershell uninstall all packages>
npm uninstall (Get-ChildItem .\node_modules).Name 
</file> 

<callout icon="true" type="important">
Note that `npm uninstall` *can* handle paths that are longer than 260 -- whereas the standard [[IT/AD/CLI/|CLI]] cannot:
* [[it/ad/npm/howto/deal_with_long_filenames]]

</callout>


### Save the Changes to the package.json File

`npm uninstall` just removes the package, but leaves the reference to the package in the `package.json` file.

If you want all mention of the package removed, use the `-S` or `-D` flags:

<sxh>
# remove from the dependencies section of package.json:
npm uninstall foobar -S 

# or from the devDependencies section of package.json:
npm uninstall foobar -D 

</sxh>

It's wise to also clear the cache:

<sxh>
npm cache clear
</sxh>
