Example Apps

These are all working apps that persist their state on Hyperclay - they change the DOM and the DOM saves itself automatically.

Every example below uses HyperclayJS — a single script tag that gives your HTML file the ability to save itself, toggle between admin and visitor modes, and persist DOM changes automatically.

We include jQuery versions as a familiar, easy-to-understand first example, but encourage you to explore the often much simpler Hyperclay-native syntax.
