Installing and uninstalling dependencies are core parts of working with any Node.js project. If you are just starting with Node.js, have a look at this article - how to install npm packages.
There are two ways to uninstall packages - manually or automatically.
To uninstall a package, you have to remove it from your
node_modules folder (that's where the code lives), and from
package.json (listed there as a project dependency). If you only remove it in the
node_modules folder and run
npm install it will be reinstalled, and if you only remove the package entry in the
package.json the package still exists in the
But don't worry. The
npm uninstall command will do both of it. Follow these steps for uninstalling dependencies:
- Identify the package you want to uninstall by looking in your package.json.
- Run the following command with the name of the package, or multiple packages separated by spaces:
npm uninstall <package1> <package2>
After successfully running the command, the NPM CLI will uninstall the package and print information to the terminal about how many packages were removed. Uninstalling removes the specified package, and all the packages it used internally as dependencies.
- Verify that it has been removed in the
package.json, this depends on your installed npm version. Since npm version 5 (released in 2017) installing or uninstalling a dependency will update the
package.jsonautomatically. Previously it was required when installing a package to add the
--saveflag to add the package entry in package.json.
Uninstall global packages
If you've installed a package globally, you can uninstall it by passing the
-g flag when uninstalling. For example, if you have Gatsby CLI globally installed and want to remove it:
npm uninstall -g gatsby
A helpful command is
npm prune, which cleans extraneous packages in your
node_modules folder. More details can be found in a future article.
