Application
Publish a website and backend code as a reachable application.
An application publishes a site (static files, Worker code, or both) to the platform and gives it a reachable address. Every publish creates a version, and a deployed version becomes the live one.
Where to store data
Use the application's own d1, kv or r2 components for runtime data such as orders and sessions, with business rules enforced by application code. Use Database for structured content, File for files and Knowledge for searchable knowledge: these are shared content stores that applications can read through public APIs, not their private runtime storage.
- Runtime capabilities: what an application can and cannot do, and its limits.
