Schema-driven forms use a single JSON Schema as the source of truth for both frontend and backend validation, eliminating duplicated rules and sync issues. This tutorial walks through building a Vue 3 + Node.js/Express app where a shared JSON Schema (validated with Ajv) drives dynamic form rendering, conditional field logic, real-time async validation (e.g., checking if an email is taken), and server-side enforcement. Key benefits include updating validation rules in one place, automatic UI updates, and consistent error handling across the stack.
