| description | Implement typed business operations with ActiveInteraction. Covers input types, composition, controller patterns, and testing. |
Typed business operations as the structured alternative to service objects.
| Service Objects | ActiveInteraction |
|---|---|
| No standard interface | Consistent .run / .run! |
| Manual type checking | Built-in type declarations |
| Manual validation | Standard Rails validations |
| Hard to compose | Native composition |
| Verbose boilerplate | Clean, self-documenting |
