🧩 Features & Usage Examples

HTTP Client

import { HttpClient, HttpMethod } from '@breadstone/ziegel-platform-http';

const client = new HttpClient({
  baseUrl: 'https://api.example.com',
  timeout: 30000,
});

// GET request
const users = await client.get<User[]>('/users');

// POST request
const newUser = await client.post<User>('/users', userData);

Request Interceptors

import { RequestInterceptor, ResponseInterceptor } from '@breadstone/ziegel-platform-http';

// Add authentication header
client.addRequestInterceptor((config) => {
  config.headers.Authorization = `Bearer ${token}`;
  return config;
});

// Handle responses
client.addResponseInterceptor(
  (response) => response,
  (error) => {
    if (error.status === 401) {
      // Handle unauthorized
    }
    return Promise.reject(error);
  },
);

REST Service Base

import { RestServiceBase } from '@breadstone/ziegel-platform-http';

class UserService extends RestServiceBase<User> {
  constructor(client: HttpClient) {
    super(client, '/users');
  }

  async getByEmail(email: string): Promise<User> {
    return this.get(`/by-email/${email}`);
  }
}

Error Handling

import { HttpError, isHttpError } from '@breadstone/ziegel-platform-http';

try {
  const data = await client.get('/api/data');
} catch (error) {
  if (isHttpError(error)) {
    console.log(`HTTP Error: ${error.status} - ${error.message}`);
  }
}
