Generative UI Approach: Model Writes JSX, Validated in Sandbox, Shipped as JSON
threepointone · x · 2026-08-21
Developer @vaibhavshn introduces jsx2ui, a generative UI approach where the model writes React-style JSX. A Cloudflare Dynamic Worker executes and validates this code in a sandbox, shipping only validated JSON to the client.
Compared to JSON patches or custom DSLs, this method leverages the model's existing knowledge of JSX syntax, reducing instruction size, improving token efficiency and accuracy, and enhancing security by avoiding untrusted code in the browser.
