SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Building frontend applications involves recurring decisions about component structure, state management, routing, and form handling. This Skill provides proven patterns and code templates for React and Vue development so you avoid reinventing common solutions and mixing business logic with presentation. ## Core Features & Use Cases - Component Patterns: Typed React components with variant props, custom hooks like useFetch for data loading, and error boundaries. - State Management: Context API providers for global state such as authentication, plus guidance on Redux and Pinia. - Routing & Forms: React Router setup with protected routes, and form validation using React Hook Form with Zod schemas. - Use Case: When asked to build a user registration form, the Skill produces a typed form component with Zod schema validation, inline error messages, and submit-state handling. ## Quick Start Ask the agent to create a React login form with email and password validation using React Hook Form and Zod.

Frequently Asked Questions about frontend-development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a reusable React component with TypeScript?▼

Define a props interface with typed fields such as variant and size, then map those props to style objects inside a functional component. The Skill demonstrates a Button component using union types and default parameter values for predictable rendering.

How to validate forms in React with React Hook Form and Zod?▼

Define a Zod schema describing each field's rules, infer the TypeScript type from it, and pass zodResolver to useForm. Register inputs with the register function and display errors from formState.errors next to each field.

When should I use Context API instead of Redux for state management?▼

Context API suits app-wide state that changes infrequently, such as the authenticated user, as shown in the AuthProvider pattern. Redux or Pinia fit better for complex, frequently updated state with many subscribers.

How do I protect routes in React Router?▼

Create a ProtectedRoute component that reads the user from an auth context and returns an Outlet when authenticated or a Navigate redirect to the login page otherwise. Nest private routes inside that layout route.

What tasks are outside the scope of frontend component development?▼

Styling and layout belong to a CSS-focused skill, backend API design belongs to a REST API skill, and rendering optimization belongs to a web performance skill. This Skill covers components, state, routing, and forms only.
