Easily Manage Node.js Versions with NVM — Complete Setup + Tips (macOS, Linux, Windows)

NVM is a command-line tool designed to easily manage multiple Node.js versions on your system. It allows seamless switching between different Node.js versions for various projects. NVM supports Windows, Linux, macOS, and other environments like WSL. Installation involves using `curl` or `wget` on macOS/Linux, followed by shell configuration and a reload. On Windows, NVM-Windows is recommended, offering a straightforward .exe installer. After installation, you can verify the NVM version using the `nvm --version` command. Basic NVM commands include installing specific versions, listing installed versions, and switching between them. You can set a global default Node.js version and update to the latest version using NVM. Additionally, you can run files or execute commands with specific Node.js versions. The `.nvmrc` file within a project directory allows version specification. Tools like `avn` can automate version switching based on the `.nvmrc` file. NVM helps to avoid version conflicts and streamline development workflows.
