01 / The story
A Person is more than a database row.
Imagine an application that tracks People. Each Person has an id, name, and age. Fjell gives identity, validation, storage, transport, and client use a home while keeping the Item recognizable.
The request in human terms
A person fills in a form and clicks Create. The system validates input, saves the Person Item, returns it, and updates the UI.
01
User
A form collects Person properties.
02
API
Express turns HTTP into an operation.
03
Library
Hooks and validators apply rules.
04
Adapter
Sequelize or Firestore persists it.
05
Cache
The result is shared with readers.
06
UI
The component renders new state.
The payoff
Changing storage does not require rewriting API handlers. Adding a client cache does not require moving business rules into React.
