How to use the command 'Remove-NodeVersion' (with examples)

The ‘Remove-NodeVersion’ command is part of ‘ps-nvm’, which is a PowerShell module used to manage different versions of Node.js runtime. This command allows users to uninstall specific Node.js versions from their system.

Use case 1: Uninstall a given Node.js version

Code:

Remove-NodeVersion 12.18.4

Motivation: The motivation behind using this example is to uninstall a specific version of Node.js that is no longer required or causing compatibility issues with the current project.

Explanation:

• Remove-NodeVersion - This is the command used to uninstall Node.js versions.
• 12.18.4 - This argument represents the specific version of Node.js that needs to be uninstalled.

Example output:

Successfully uninstalled Node.js version 12.18.4.

Use case 2: Uninstall multiple Node.js versions

Code:

Remove-NodeVersion 12.18.4, 14.15.1, 16.3.0

Motivation: The motivation behind using this example is to uninstall multiple Node.js versions at once, saving time and effort.

Explanation:

• Remove-NodeVersion - This is the command used to uninstall Node.js versions.
• 12.18.4, 14.15.1, 16.3.0 - These arguments represent the specific versions of Node.js that need to be uninstalled. Multiple versions can be specified by separating them with commas.

Example output:

Successfully uninstalled Node.js versions 12.18.4, 14.15.1, and 16.3.0.

Use case 3: Uninstall all currently-installed versions of Node.js 20.x

Code:

Get-NodeVersions -Filter ">=20.0.0 <21.0.0" | Remove-NodeVersion

Motivation: The motivation behind using this example is to uninstall all Node.js versions that fall within the specified range, in this case, versions 20.x.

Explanation:

• Get-NodeVersions -Filter ">=20.0.0 <21.0.0" - This command filters the currently installed Node.js versions and selects only the ones that are within the range of “>=20.0.0” and “<21.0.0”.
• | - This pipe symbol is used to pass the output of the Get-NodeVersions command to the Remove-NodeVersion command.
• Remove-NodeVersion - This is the command used to uninstall Node.js versions.

Example output:

Successfully uninstalled Node.js versions 20.3.0, 20.4.1, 20.8.0, etc.

Use case 4: Uninstall all currently-installed versions of Node.js

Code:

Get-NodeVersions | Remove-NodeVersion

Motivation: The motivation behind using this example is to uninstall all currently installed versions of Node.js.

Explanation:

• Get-NodeVersions - This command lists all currently installed versions of Node.js.
• | - This pipe symbol is used to pass the output of the Get-NodeVersions command to the Remove-NodeVersion command.
• Remove-NodeVersion - This is the command used to uninstall Node.js versions.

Example output:

Successfully uninstalled Node.js versions 12.18.4, 14.15.1, 16.3.0, 20.3.0, 20.4.1, 20.8.0, etc.

Conclusion:

The ‘Remove-NodeVersion’ command is a useful tool for managing Node.js runtime versions using ‘ps-nvm’. It allows users to uninstall specific or multiple versions of Node.js from their system. Whether it’s removing a single version, multiple versions, specific ranges, or all currently installed versions, this command provides flexibility in managing Node.js runtime.
