Installing npm and Node.js for Windows

If you want to use Node-RED on Windows, you must install npm and Node.js via the following website:

https://nodejs.org/en/#home-downloadhead.

You can get the Windows Installer of Node.js directly there. After that, follow these steps:

1. Access the original Node.js website and download the installer.

   You can choose both versions – Recommended or Latest Features – but in this book, you should use the Recommended version:

   Figure 2.1 – Choosing a Recommended version installer

2. Click the msi file you downloaded to start installing Node.js. It includes the current version of npm. Node-RED is running on the Node.js runtime, so it is needed.
3. Simply click the buttons of the dialog windows according to the installation wizard, though there are some points to bear in mind during the install.
4. Next, you need to accept the End-User License Agreement:
