Custom asset and content management

Native support for images, videos, SVGs, and text with extensible APIs for custom formats like 3D models or CAD files. Ideal for domain-specific apps with specialized content handling beyond standard web formats.

Register custom handlers that detect and transform any content type into application-specific shapes. Perfect for apps where pasted code becomes syntax-highlighted blocks or uploaded designs become interactive prototypes.

Define custom validation, transformation, and optimization rules for each content type. Build specialized workflows like automatic image resizing, metadata extraction, or security scanning during content import.

Customize viewport culling and asset optimization to handle large files, with size limits, progressive loading, and quality tweaks keeping the canvas responsive.

The content recognition engine routes dropped or pasted content through your registered handlers. Each handler gets typed content with metadata and context, then returns shape creation instructions. Handlers can be chained for complex workflows, with priority and fallback rules ensuring everything is processed correctly.

The asset store interface abstracts storage operations behind a clean API that supports upload, resolution, and removal operations. Built-in implementations include base64 embedding for development and IndexedDB for offline applications. Custom stores integrate with cloud providers through simple async methods. The system handles temporary previews, upload progress tracking, and automatic failover scenarios.

Viewport culling skips off-screen assets while keeping selected items editable. Uploads apply size and quality adjustments automatically, generating multiple representations for zoom and display contexts. Memory is optimized through garbage collection and smart caching.
