How to use the command 'Install-NodeVersion' (with examples)
This article provides examples of how to use the Install-NodeVersion command, which is part of the ps-nvm PowerShell module. The Install-NodeVersion command is used to install specific versions of the Node.js runtime for ps-nvm.
Use case 1: Install a specific Node.js version
Code:
Install-NodeVersion 12.22.1
Motivation:
Installing a specific version of Node.js can be useful when developing and testing applications that require a specific runtime version. This ensures that the application runs consistently across different environments.
Explanation:
The command Install-NodeVersion is followed by the desired version of Node.js to be installed. In this example, the version 12.22.1 is specified.
Example output:
Installing Node.js version 12.22.1...
Node.js version 12.22.1 has been successfully installed.
Use case 2: Install multiple Node.js versions
Code:
Install-NodeVersion 10.16.3, 14.17.0, 16.3.0
Motivation:
Installing multiple Node.js versions can be useful when testing the compatibility of an application across different runtime versions or when working on projects that require specific versions for different components.
Explanation:
The command Install-NodeVersion is followed by a comma-separated list of the desired Node.js versions to be installed. In this example, the versions 10.16.3, 14.17.0, and 16.3.0 are installed.
Example output:
Installing Node.js version 10.16.3...
Node.js version 10.16.3 has been successfully installed.
Installing Node.js version 14.17.0...
Node.js version 14.17.0 has been successfully installed.
Installing Node.js version 16.3.0...
Node.js version 16.3.0 has been successfully installed.
Use case 3: Install latest available version of Node.js 20
Code:
Install-NodeVersion ^20
Motivation:
Installing the latest available Node.js version in a specific major version (e.g., version 20.x.x) can be useful when wanting to ensure compatibility with the latest features and bug fixes available in that major version.
Explanation:
The command Install-NodeVersion is followed by the desired major version of Node.js prefixed with a caret (^). In this example, the latest available version within the 20.x.x range is installed.
Example output:
Installing latest available version of Node.js 20...
Node.js version 20.7.0 has been successfully installed.
Use case 4: Install the x86/x64/arm64 version of Node.js
Code:
Install-NodeVersion 14.17.0 -Architecture x64
Motivation:
Installing a specific architecture of Node.js (x86, x64, or arm64) can be useful when the target system has a specific architecture requirement or when specific features or optimizations provided by a specific architecture are desired.
Explanation:
The command Install-NodeVersion is followed by the desired Node.js version and the -Architecture flag, which is used to specify the desired architecture (x86, x64, or arm64). In this example, the x64 version of Node.js version 14.17.0 is installed.
Example output:
Installing x64 version of Node.js 14.17.0...
Node.js version 14.17.0 (x64) has been successfully installed.
Use case 5: Use a HTTP proxy to download Node.js
Code:
Install-NodeVersion 12.22.1 -Proxy http://example.com
Motivation:
Using a HTTP proxy to download Node.js can be useful when the system is behind a corporate firewall or when there are network restrictions that require proxy usage. This ensures that the Node.js installation is not blocked by network limitations.
Explanation:
The command Install-NodeVersion is followed by the desired Node.js version and the -Proxy flag, which is used to specify the HTTP proxy to be used for downloading Node.js. In this example, the Node.js version 12.22.1 is installed using the HTTP proxy http://example.com.
Example output:
Installing Node.js version 12.22.1 using HTTP proxy http://example.com...
Node.js version 12.22.1 has been successfully installed.
Conclusion:
The Install-NodeVersion command provides a convenient way to install specific versions of the Node.js runtime for use with ps-nvm. Whether installing a single version, multiple versions, the latest available version, a specific architecture, or using a HTTP proxy, this command offers flexibility in managing the required Node.js environments for development and testing purposes.
