This approach: + +- **Reduces boilerplate code** - Most UI wiring is done via configuration +- **Improves maintainability** - Changes to UI structure can be made in JSON +- **Enables rapid prototyping** - New features can be scaffolded from config +- **Promotes reusability** - Atomic components and hooks are truly reusable +- **Simplifies testing** - Playbooks defined in JSON for E2E tests + +## Architecture Components + +### 1. Component Tree Renderer (`src/utils/componentTreeRenderer.tsx`) + +The core of the config-driven architecture. It reads component tree definitions from `features.json` and dynamically renders React components. + +**Features:** +- Template interpolation: `{{variable}}` syntax +- Conditional rendering: `condition` property +- Loops: `forEach` property for arrays +- Action mapping: Maps string action names to functions +- Icon rendering: Automatic Material-UI icon resolution + +**Example usage:** + +```tsx +import { ComponentTreeRenderer } from '@/utils/componentTreeRenderer'; +import { getComponentTree } from '@/utils/featureConfig'; + +const tree = getComponentTree('DashboardStatsCards'); + + {} }, + state: { isOpen: false } + }} +/> +``` + +### 2. Hooks (`src/hooks/`) + +Small, focused hooks for data fetching and business logic: + +#### `useApiCall` +Generic hook for API calls with loading/error states. + +```tsx +const { data, loading, error, execute } = useApiCall(); + +// Execute API call +await execute('/api/endpoint', { + method: 'POST', + body: { data: 'value' } +}); +``` + +#### `useTables` +Manage database tables (list, create, drop). + +```tsx +const { tables, loading, error, createTable, dropTable } = useTables(); + +// Create a table +await createTable('users', [ + { name: 'id', type: 'INTEGER' }, + { name: 'name', type: 'VARCHAR' } +]); +``` + +#### `useTableData` +Fetch and manage table data. + +```tsx +const { data, loading, error, fetchTableData } = useTableData('users'); +``` + +#### `useColumnManagement` +Column operations (add, modify, drop). + +```tsx +const { addColumn, modifyColumn, dropColumn } = useColumnManagement(); + +await addColumn('users', { + columnName: 'email', + dataType: 'VARCHAR' +}); +``` + +### 3.
