SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

All frontend types are defined in frontend/types/index.ts and patterns ensure the frontend safely models backend data for consistent API integration, catch type errors early, and improve developer experience.

Core Features & Use Cases

  • Guidance for creating TypeScript type definitions that follow existing patterns from frontend/types/index.ts.
  • Examples include User, Task, ApiResponse, and authentication-related types, with field naming conventions and snake_case mapping for API integration.
  • Use cases span UI components, API clients, and form handling where strong typing reduces runtime errors.

Quick Start

Inspect frontend/types/index.ts and align or extend types to reflect backend responses, ensuring all API interactions are type-safe.

FAQPage Schema
How do I define TypeScript types for frontend UI components that map to backend API responses?

Define TypeScript types by aligning frontend interfaces with backend API structures, using snake_case field mappings for API integration. This ensures consistent type safety across UI components, API clients, and form handling.

What TypeScript patterns should I use for structuring API response types?

Use TypeScript interfaces for objects like User and Task, type aliases for unions, and generics for ApiResponse shapes. These patterns catch type errors early and improve developer experience during API integration.

When do I need to align frontend types with backend API naming conventions?

Align frontend types with backend API naming conventions when integrating API responses, especially mapping snake_case backend fields to frontend naming conventions. This ensures type-safe API interactions across the application.

Can I use TypeScript type aliases and generics together for safer API client integration?

Yes, combine TypeScript type aliases for union types and generics for ApiResponse to model backend data safely. This approach reduces runtime errors in API clients and form handling scenarios.

Does this approach to frontend TypeScript types work for form handling and authentication flows?

Frontend TypeScript types apply to form handling and authentication flows by defining User and authentication-related types. Strong typing in these scenarios reduces runtime errors and ensures consistent API integration.

What's the best way to structure TypeScript type definitions for a frontend application?

Structure TypeScript type definitions in a central file like frontend/types/index.ts, following patterns for User, Task, and ApiResponse. This approach ensures all API interactions remain type-safe and consistently modeled.
