JSON Schema form

React chapter 65 · RJSF · schema + uiSchema · source: rjsf-team/react-jsonschema-form

The problem

An admin form is 40 hand-written inputs. The API adds "vatNumber". Engineering ships a frontend PR. Every tenant, every CMS entity, every "settings" blob wants a different shape — and the JSX cannot keep up.

The pattern that fixes it

The form is data: a JSON Schema describes fields and validation; an optional uiSchema picks widgets (textarea, select). A generic renderer maps properties → inputs. Back-office UIs change by editing JSON, not components. RJSF is that generator.
