N
n is a command line version manager and binary manager for the Node.js runtime environment. It functions as a runtime environment switcher, allowing for the installation and management of multiple Node.js versions to maintain compatibility across different projects.
The tool orchestrates the downloading and caching of Node.js binaries from official or custom distribution mirrors. It enables switching between installed versions via a command line interface or interactive menu, providing the ability to execute scripts using specific versions from a local cache without performing a full system installation.
The system covers runtime administration, including version discovery, multi-version installation, and version removal. It also handles cross-architecture binary resolution, download mirror configuration, and system diagnostics to resolve environment configuration issues.
Features
- Runtime Version Managers - Provides a command-line and interactive interface to toggle between different installed Node.js runtime versions.
