Svelte 5

Define Svelte components, generate prompts, and render streamed OpenUI Lang with @openuidev/svelte-lang.

Integration overview

How it connects to OpenUI

Svelte component definitions and Zod schemas become one component library. The package generates the model prompt and its Renderer resolves streamed statements into Svelte components.

The integration path

  1. 1

    Describe the interface

    Generate a component prompt from the same OpenUI library that will render the response.

  2. 2

    Stream structured output

    Let Svelte 5 own its part of the stack while OpenUI Lang travels as incremental text or mapped agent events.

  3. 3

    Render and interact

    Parse the stream with the matching OpenUI runtime, render real components, and return validated actions to the application.
