XDN only supports Node.js version 12 and higher
If you do not have Node.js installed on your system, download and install it from official Node.js downloads page. Select the download labeled "LTS (Recommended For Most Users)" and that matches your operating system, and run the installer. Note that the installer for Node.js will also install npm.
To add the XDN to an existing app, run the following:
npm i -g @xdn/cli xdn init
To create a new XDN app, run:
npm create xdn-app@latest
... or using yarn ...
yarn create xdn-app@latest
