Frontend Data Api Layer

When to use this skill

• Abstracting API calls
• Centralizing API logic
• Type-safe API layer

Workflow

• ] Create API client
• ] Define API methods
• ] Handle errors centrally
• ] Type request/response
• ] Add interceptors

Instructions

API Client

typescript
// api/client.ts
import axios from 'axios';

export const apiClient = axios.create({
  baseURL: import.meta.env.VITE_API_URL,
  headers: {
    'Content-Type': 'application/json'
  }
});

apiClient.interceptors.request.use((config) => {
  const token = localStorage.getItem('token');
  if (token) config.headers.Authorization = `Bearer ${token}`;
  return config;
});

API Methods

typescript
// api/users.ts
export const usersApi = {
  getAll: () => apiClient.get<User[]>('/users'),
  getById: (id: string) => apiClient.get<User>(`/users/${id}`),
  create: (data: CreateUserDto) => apiClient.post<User>('/users', data),
  update: (id: string, data: UpdateUserDto) => 
    apiClient.put<User>(`/users/${id}`, data),
  delete: (id: string) => apiClient.delete(`/users/${id}`)
};

Resources

• Centralize all API calls
• Type request/response
• Handle auth in interceptors
