Uninstalling npm modules in Node.js is a straightforward process that can be done using the npm command-line interface (CLI). This allows you to easily remove unwanted or unused packages from your Node.js project. In this answer, we will explore two methods for uninstalling npm modules in Node.js.
Method 1: Using the npm uninstall command
The simplest way to uninstall an npm module is by using the npm uninstall command followed by the module name. Here is the general syntax:
npm uninstall <module_name>
Replace <module_name> with the actual name of the module you want to uninstall.
For example, to uninstall the lodash module, you would run:
npm uninstall lodash
This command will remove the lodash module from your project, deleting its files and dependencies.

Method 2: Removing the module manually
If you prefer a more manual approach, you can uninstall an npm module by removing its package folder from the node_modules directory. Here are the steps:
1. Navigate to the root directory of your Node.js project using the command line.
2. Locate the node_modules directory. This is where all the installed npm modules are stored.
3. Find the folder corresponding to the module you want to uninstall.
4. Delete the folder corresponding to the module you want to uninstall.
For example, if you want to uninstall the express module, you would navigate to your project’s node_modules directory and delete the express folder.
Keep in mind that this method does not remove the module from your project’s package.json file. If you want to completely remove the module from your project, you should also remove it from the dependencies or devDependencies section of your package.json file.
Best practices
When uninstalling npm modules in Node.js, it is good practice to follow these recommendations:
1. Regularly review and remove any unused or unnecessary modules from your project to keep it lean and maintainable.
2. Before uninstalling a module, make sure it is not a dependency for any other module in your project. Removing a module that is still used by other parts of your code can break your application.
3. Use a version control system like Git to track changes in your project. This allows you to revert any unintended changes caused by the removal of modules.
4. Always test your code after uninstalling a module to ensure that your application still functions as expected.
