How to Set Node.js Installation Location using 'Set-NodeInstallLocation' (with examples)

The Set-NodeInstallLocation command is a handy feature of ps-nvm, a Node.js version manager for PowerShell. This command lets users change the default Node.js installation directory, thereby offering flexibility in managing where Node.js versions are stored. Such customization is crucial, especially when dealing with shared systems, limited storage spaces, or organizational storage conventions. It’s important to note that this command can only be executed within a PowerShell environment. More details on this can be found on its GitHub page .

Use case: Change the Node.js install location to a specified directory

Code:

Set-NodeInstallLocation C:\NodeVersions

Motivation:

Changing the default installation path for Node.js using the Set-NodeInstallLocation command is incredibly beneficial for developers who have specific folder structures or limited system spaces. You might, for instance, want to install Node.js versions on an external drive or a designated folder within your file system to keep your projects or applications organized. This is especially useful in environments where different applications have different storage requirements or security policies dictating where software can be stored.

Explanation:

• Set-NodeInstallLocation: This is the command from the ps-nvm suite that sets a custom location for Node.js installations. It’s particularly useful for ensuring that Node.js installations don’t conflict with existing software or storage setups.

• C:\NodeVersions: This argument specifies the directory ps-nvm will use to create a new .nvm subdirectory where Node.js versions will be installed. In this example, C:\NodeVersions is a path on the C: drive, effectively directing all future installations of Node.js to be stored there. Choosing a specific directory like C:\NodeVersions can improve organization, allowing easy management of Node.js versions and separation from other software applications.

Example Output:

After executing the above command, the ps-nvm system configures itself such that any subsequent installations of Node.js are directed to the C:\NodeVersions\.nvm directory. You might see a confirmation message in PowerShell confirming this action, informing you that the default Node.js path has been updated, and any old versions will no longer be accessible unless this path reassignment is reverted.

Conclusion:

The Set-NodeInstallLocation command is a powerful tool for customizing your Node.js development environment within the PowerShell ecosystem. By understanding how to modify the default Node.js installation location, developers gain greater control over their filesystem, ensuring Node.js setups are tailored to specific project needs, storage capabilities, and organizational policies.
