Functions

Function	Description	Example
get	Perform GET request with retry	dphelper.fetch.get(url, options)
post	Perform POST request with JSON	dphelper.fetch.post(url, body, options)

Description

HTTP request utilities:

• GET - Fetch data with automatic retries

• POST - Send JSON data with automatic JSON headers

• Retry - Exponential backoff on failure

• Error Handling - Automatic retry on network errors

Usage Examples

GET Request

// Simple GET request
const response = await dphelper.fetch.get('https://api.example.com/data');
const data = await response.json();

// GET with options
const users = await dphelper.fetch.get('/api/users', {
  headers: { 'Authorization': 'Bearer token' }
});

POST Request

// POST JSON data
const response = await dphelper.fetch.post('/api/users', {
  name: 'John',
  email: '[e-mail]'
});

// POST with custom headers
const response = await dphelper.fetch.post('/api/upload', formData, {
  headers: { 'X-Custom-Header': 'value' }
});

Error Handling with Retry

// Automatic retry on failure
async function fetchWithRetry(url, options = {}) {
  try {
    const response = await dphelper.fetch.get(url, options);
    return await response.json();
  } catch (error) {
    console.error('Fetch failed:', error);
    return null;
  }
}

API Integration

class ApiClient {
  constructor(baseUrl) {
    this.baseUrl = baseUrl;
  }

  async get(endpoint) {
    const response = await dphelper.fetch.get(`${this.baseUrl}${endpoint}`);
    return response.json();
  }

  async post(endpoint, data) {
    const response = await dphelper.fetch.post(`${this.baseUrl}${endpoint}`, data);
    return response.json();
  }
}

const api = new ApiClient('https://api.example.com');
const data = await api.get('/items');
