Frontend Integration

Connect your React, Vue, Angular, or mobile apps to Mock API Builder with framework-specific examples

Integration Overview

Mock API Builder provides standard REST APIs that work with any HTTP client. This guide shows you how to integrate with popular frontend frameworks and tools.

Web Frameworks

React, Vue, Angular, Svelte—works with all modern web frameworks

Mobile Apps

React Native, Flutter, Swift, Kotlin—native mobile integration

HTTP Clients

fetch, Axios, TanStack Query, SWR—use your preferred client

State Management

Redux, Zustand, Context API—integrate with any state solution

React / Next.js

Using fetch() with useState
javascript
Using TanStack Query (React Query)
Recommended
javascript
Using Axios with Custom Hook
javascript

Vue.js

Using Composition API with fetch
javascript
Using Axios with Composable
javascript

Angular

Using HttpClient Service
javascript

React Native

Mobile App Integration

Environment Configuration

Use environment variables to easily switch between mock and production APIs:

React / Next.js (.env.local)
bash

Usage: process.env.NEXT_PUBLIC_API_URL

Vue.js (.env)
bash

Usage: import.meta.env.VITE_API_URL

Angular (environment.ts)
javascript

Usage: environment.apiUrl

CORS Configuration

CORS is Automatically Handled

Mock API Builder automatically includes the necessary CORS headers for all responses:

  • Access-Control-Allow-Origin: *
  • Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE
  • Access-Control-Allow-Headers: Content-Type, Authorization

No additional configuration needed—calls from any domain will work.

Best Practices

  • Use environment variables to switch between mock and production APIs
  • Create an API service/module to centralize all API calls
  • Handle loading and error states for better user experience
  • Use data fetching libraries like TanStack Query or SWR for caching and synchronization
  • Add request/response interceptors for authentication, logging, and error handling
  • Test with mock data first before connecting to production APIs
  • Use TypeScript interfaces to type your API responses for better developer experience
