Appendix B Installing Node.js on macOS and Windows
This appendix ensures you’re ready to build and evolve the sample Node.js web application by guiding you through installing Node.js on macOS and Windows. The focus is on using the latest long-term support (LTS) release because it’s the most stable, broadly supported option. The simplest paths recommended are either installing directly from the official Node.js installer or using a version manager, keeping the setup reliable and easy to maintain.
On macOS, two approaches are advised: download the official installer or use nvm to manage versions. Other installers exist but can introduce unnecessary complexity. The LTS release supports both Apple Silicon and Intel, so no CPU-specific steps are required. With nvm, you install the LTS release and then verify the installation by checking the Node.js version, giving you a clean, upgradable setup.
On Windows, the recommended route is to install the LTS release using the official installer. Before downloading, verify whether the system is 64-bit or 32-bit via the System Information tool, then choose the appropriate installer. The appendix notes an example current LTS (18.13.0), emphasizes that most code in the book is compatible across versions, and suggests nvm-windows if you need to manage multiple Node.js versions on Windows.
