🚀 How to Use/Example

install_node_and_modules

to install the latest version of Node.js with no additional Modules. If you want to define a specified Version and install Modules use something like this:

NODE_VERSION=20 NODE_MODULE="yarn@latest,@vue/[email protected]" install_node_and_modules

🧩 User-Configurable Variables

Variable	Description	Default Value
NODE_VERSION	Specifies the major version of Node.js to install (e.g., 20, 22).	22
NODE_MODULE	Comma-separated list of global npm modules to install or update. Examples: • yarn@latest • @vue/[email protected] • typescript	(empty)

🔧 Notes

Global npm packages are only processed if NODE_MODULE is set. If the requested module version is already installed, it is skipped. Modules are updated if the installed version does not match the requested one (unless latest is used). On failure, the script exits with exit 1.
