This command forcefully clears the npm cache, removing any stored data from your system and ensuring that no remnants of npm remain. It’s an essential step for a fresh start or before installing a different version of Node.js and npm.

Deep Clean: Removing Residual Files

After uninstalling Node.js and npm using the basic steps, it’s time to ensure no residual files are left lurking in your system. These leftovers can take up unnecessary space or cause conflicts with future installations. Let’s explore how to locate and remove these remnants for a truly clean system.

Locate and Delete npm Cache and Global Packages

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 This command removes all cached data, ensuring that no outdated or unnecessary package data remains.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.

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.
