• C:\Program Files (x86)\Nodejs
• C:\Program Files\Nodejs
• C:\Users\{User}\AppData\Roaming\npm or open run and type appdata and click ok and open roaming there you will find npm.
• C:\Users\{User}\AppData\Roaming\npm-cache or open run and type appdata and click ok and open roaming there you will find npm-cache.
• C:\Users\{User}\.npmrc
• C:\Users\{User}\package.json
• C:\Users\{User}\package-lock.json
• C:\Users\{User}\AppData\Local\Temp\npm-*                       

Step 6: After that check the environment path variables and make sure no references to npm or Node.js exist.

Step 7: If Node.js is still not uninstalled then open the command prompt and type the below command:

where node

Step 8: If Node.js is not uninstalled the command will output the location of Node.js. Go to that location and uninstall the directory.

Even after uninstallation, npm cache and global packages might still reside on your computer. Here’s how you can find and remove them, ensuring a comprehensive cleanup.

Finding and Clearing npm Cache

The npm cache is a repository for the packages that npm accesses and stores temporarily. Over time, this cache can grow significantly. Here’s how to find and remove it:

npm cache verify

# Output:
# Cache verified: X items, Y MB

This command helps you verify the current state of the cache, including its size and the number of cached items. After verifying, you can proceed to clear it:

npm cache clean --force

# Output:
# Cache cleaned.

The --force flag is necessary because, by default, npm prevents cache cleaning to avoid potential data loss. This command removes all cached data, ensuring that no outdated or unnecessary package data remains.

Removing Global npm Packages

Global npm packages are installed system-wide and can remain after Node.js and npm are uninstalled. To list global npm packages:

npm list -g --depth=0

# Output:
# /usr/local/lib
# ├── package-name@version

This command lists all global packages installed on your system. To remove them, you can use the npm uninstall -g command followed by the package name. Here’s an example:

npm uninstall -g package-name

# Output:
# removed 1 package in Xs

Removing global packages ensures that no unnecessary packages linger, which could interfere with future installations or take up valuable disk space.

Manual Cleanup of Residual Directories

After using commands to remove npm and Node.js, some directories might still exist. Manually checking and removing these directories is crucial for a complete cleanup. Common locations include /usr/local/lib/node_modules for Node.js and /usr/local/bin for npm binaries. Use your system’s file explorer or terminal to navigate and delete these directories.

By following these advanced steps, you ensure a thorough removal of Node.js and npm from your system, paving the way for a clean environment for future projects.

Alternative Uninstall Methods

These approaches can vary from using third-party uninstaller tools to leveraging package managers like Homebrew on macOS. Let’s dive into these methods, weighing their benefits and potential drawbacks.

Third-Party Uninstaller Tools

Third-party uninstaller tools can provide a more comprehensive cleanup than the built-in uninstallation process. These tools often scan for residual files and directories that manual or command-line uninstallations might miss.

However, it’s essential to choose a reputable uninstaller to avoid introducing malware or other unwanted software onto your system. Research and select a tool with positive reviews and a strong track record.

Using Homebrew on macOS

For macOS users, Homebrew is a beloved package manager that can also manage uninstallations. If you installed Node.js and npm via Homebrew, uninstalling is straightforward with a single command:

brew uninstall node

# Output:
# Uninstalling /usr/local/Cellar/node/XX.X.X... (X,XXX files, XX.XMB)
# node XX.X.X has been uninstalled!

This command removes Node.js and npm, including all the files and directories associated with the installation. The output confirms the successful uninstallation, listing the number of files and the total space reclaimed.

Pros and Cons

Pros:
– Third-party tools and package managers like Homebrew can automate the uninstallation process, making it more thorough and less time-consuming.

This code snippet demonstrates how to use JavaScript in conjunction with Node Version Manager (nvm) to manage multiple Node.js versions on a system. While not directly uninstalling Node.js, it provides a way to switch between different versions, achieving a similar outcome. The code defines functions to execute shell commands and switch between Node.js versions using nvm. This allows for flexibility in development environments where different projects may require specific Node.js versions.

While the provided instructions are for manual uninstallation steps on Windows, there’s no direct JavaScript code involved in the process. Uninstalling software like Node.js typically involves system-level operations and interacting with the Windows Control Panel or package managers.

However, let’s explore how you might use JavaScript to achieve similar results in a different context:

Scenario: Managing Node.js versions with nvm (Node Version Manager)

nvm is a popular tool for managing multiple Node.js versions on a single machine. Here’s how you can use JavaScript along with nvm to switch between Node.js versions, which indirectly achieves a similar outcome to uninstalling and reinstalling:

const { exec } = require('child_process');

// Function to execute shell commands
function runCommand(command) {
  return new Promise((resolve, reject) => {
    exec(command, (error, stdout, stderr) => {
      if (error) {
        reject(error);
      } else {
        resolve(stdout.trim());
      }
    });
  });
}

// Example usage:
async function switchNodeVersion(version) {
  try {
    // Check if the version is installed
    const installedVersions = await runCommand('nvm ls');
    if (!installedVersions.includes(version)) {
      console.log(`Installing Node.js version ${version}`);
      await runCommand(`nvm install ${version}`);
    }

    // Use the specified version
    console.log(`Using Node.js version ${version}`);
    await runCommand(`nvm use ${version}`);
  } catch (error) {
    console.error('Error:', error);
  }
}

// Example: Switch to Node.js version 14.18.0
switchNodeVersion('14.18.0');

Explanation:

1. Import exec: We import the exec function from the child_process module to execute shell commands.
2. runCommand Function: This helper function executes a given shell command and returns a Promise that resolves with the command’s output.
3. switchNodeVersion Function:
   • It takes a Node.js version as input.
   • It checks if the version is already installed using nvm ls.
   • If not installed, it uses nvm install to install the version.
   • Finally, it uses nvm use to switch to the specified version.

Remember: This example requires having nvm installed and configured on your system.

Limitations:

• This approach doesn’t truly «uninstall» Node.js versions; it manages them within nvm.
• It’s specific to using nvm and may not be applicable to other package managers or environments.

• Global Packages: If you’ve installed global packages using npm, you might want to list them before uninstalling using npm list -g --depth=0. This can help you decide whether to reinstall them later.
• Project Dependencies: If you have projects that rely on specific Node.js or npm versions, make sure to note those versions before uninstalling. This will ensure you can recreate the correct environment later.
• Registry Configuration: In some cases, you might have modified the npm registry configuration (e.g., using a private registry). Remember to back up or document these settings if you plan to restore them after reinstallation.
• Third-Party Tools: If you’ve used any third-party tools related to Node.js or npm (e.g., task runners, build tools), consider their compatibility with the new Node.js version you might install.
• Backup Important Data: As with any software uninstallation, it’s a good practice to back up any important data or projects before proceeding. This ensures you don’t lose any critical information during the process.

By following the outlined steps, you can effectively remove Node.js and npm from your Windows system. This process involves using the Control Panel, clearing the npm cache, manually deleting remaining files (optional), checking environment variables (optional), and restarting your computer. Remember to consider additional factors such as global packages, project dependencies, registry configurations, third-party tools, and data backups to ensure a smooth uninstallation process. Whether you’re preparing for a fresh installation or exploring alternative development tools, these instructions provide a clear roadmap for successfully uninstalling Node.js and npm from your Windows environment.
