Base44 entities

Entities are JSON-schema objects stored as base44/entities/<Name>.jsonc; writing the file is what defines the data model. The platform applies each entity’s rls rules on every app-user request.

Pick the reference for this app

Determine the app profile first. Call GET /api/apps/{app_id}/agent-profile (over the Base44 MCP execute_api tool, or with your Base44 CLI token); it returns the framework, app type, runtime, entitlements and the exact reference files to read. Without it, detect from the project files: src/routes/__root.* and src/routeTree.gen.ts mean TanStack Start; app/_layout.* means a native mobile (Expo) app; otherwise it is a Vite SPA.
