Schema files using the `material-ui-json-schema-viewer` package.\n\n## Usage\n\nVisit the application with a URL parameter pointing to a JSON Schema file:\n\n```\nhttps://json-schema-viewer.val.run/?url=\n```\n\nFor example:\n```\nhttps://json-schema-viewer.val.run/?url=https://creativeprojects.github.io/resticprofile/jsonschema/config.json\n```\n\n## Features\n\n- Fetches and displays JSON Schema from any URL\n- Renders the schema using the Material UI JSON Schema Viewer component\n- Supports all JSON Schema features including nested objects, arrays, and references\n- Minimal UI with no distractions - only shows the schema viewer\n- Handles errors gracefully\n- Material Design styling\n\n## Implementation Details\n\n- Built with React 18.2.0 and Hono 3.11.7\n- Uses the `material-ui-json-schema-viewer` package for schema rendering\n- Uses Material UI v4 for styling and components\n- Follows the recommended Val Town project structure\n- Clean separation of backend and frontend code\n\n## Project Structure\n\n- `/index.ts` - Entry point that re-exports the backend\n- `/backend/index.ts` - Hono application with API endpoints and route handlers\n- `/frontend/index.html` - HTML template\n- `/frontend/app.jsx` - React application with Material UI
