React 19

Modern React patterns and anti-pattern detection for React 19 projects.

Enabled Rules

Rule	Severity	Description
`quality/no-deprecated-api`	block	Catches deprecated React APIs (`componentDidMount`, `defaultProps` on function components)
`quality/naming-conventions`	block	PascalCase components, `use`-prefixed hooks
`quality/anti-patterns`	warn	Detects common React anti-patterns
`quality/hallucination-guard`	warn	Verifies imported React hooks and components exist
`quality/import-aliases`	block	Enforces clean import paths

import { defineConfig } from '@solanticai/vguard';

export default defineConfig({
  presets: ['react-19'],
});

No class component patterns — Blocks componentDidMount, componentWillUnmount, and other lifecycle methods. Use hooks instead.
Naming conventions — Components must be PascalCase (UserProfile, not userProfile). Hooks must start with use (useAuth, not getAuth).
Anti-pattern detection — Warns on inline object/array creation in JSX props, missing key props in lists, and direct state mutation.
Hallucination guard — AI tools sometimes import hooks or components that don't exist. This rule verifies all imports resolve to real files.
Clean imports — Enforces @/ aliases for cross-directory imports.
