json-render

Detailed Introduction

json-render is an open-source framework that constrains natural language or model outputs into structured JSON so AI only uses a predefined component catalog to describe UIs. This approach makes AI output predictable and safer to render. The project provides a core type system, a React renderer, and example apps to streamline AI-driven UI pipelines into renderable, interactive frontend components.

Main Features

• Define available components and actions in a catalog as guardrails to keep model outputs within permitted boundaries.
• Support streaming generation and progressive rendering to improve interactivity and reduce time-to-first-render.
• Built-in validation and schema checks (e.g., zod) to guarantee output correctness.
• Ships React renderer and example projects for easy integration and extension.

Use Cases

• Convert natural-language prompts into dashboards, reports, and visualization components.
• Serve as a guardrail layer where model outputs require provable constraints before rendering.
• Act as a frontend integration layer to render responses from RAG, LLMs, or other intelligent services into safe, interactive UI.

Technical Features

• Monorepo with packages such as @json-render/core and @json-render/react allowing modular adoption.
• Schema-driven validation (zod) for component props and actions to ensure type-safety and stability.
• Action declarations with external callback binding enable mapping user interactions to backend operations.
• Apache-2.0 license, active community, and playground/example apps for quick onboarding.
