Hyper is a reactive, server-rendered web framework for Clojure.
It renders interfaces as Hiccup on the server and uses Server-Sent Events to automatically patch the browser’s DOM whenever application state changes.
The framework is built on Datastar, Reitit and Chassis. Applications can provide interactive, real-time interfaces without a client-side framework, JSON API or handwritten JavaScript. Hyper is currently in active alpha development and requires JDK 21 or later.
This is free and open source software.
Key Features
- Server-rendered reactive interfaces written in Clojure and Hiccup.
- Automatic DOM updates delivered over Server-Sent Events.
- Global, session, browser-tab and URL-backed state cursors.
- Server-side actions triggered by browser events.
- Client-side reactive signals for immediate interface updates.
- Clojure expressions compiled into Datastar expressions.
- Optimistic values for responsive dragging, resizing and slider controls.
- File uploads with progress reporting and streaming to temporary files.
- Reitit routing with parameter coercion, custom error pages and live reloading.
- Support for standard Ring middleware and render middleware.
- Managed view lifecycles and automatic resource cleanup.
- Uses JDK virtual threads for per-tab rendering loops.
