@delgadotrueba/http

A personal HTTP service library featuring both httpService for real-world API interactions and httpMockService for testing and mock API simulations.

Installation

npm install @delgadotrueba/http --save

Import

Commonjs

const {
  HttpInterfaceService,
  HttpService,
  HttpMockService,
} = require('@delgadotrueba/http');

const http: HttpInterfaceService = env.production ? new HttpService() : new HttpMockService();

ESM

import { HttpInterfaceService, HttpService, HttpMockService } from '@delgadotrueba/http';

const http: HttpInterfaceService = env.production ? new HttpService() : new HttpMockService();

Usage

HttpService API

// env.production = true

const http: HttpInterfaceService = env.production ? new HttpService() : new HttpMockService();

http.get<any>({ endpoint: url }).then(async (response: any) => {
      switch (response.status) {
        case 200:
          console.log(await response.json());
          break;

        default:
          break;
      }
}).catch((error) => {
    switch (error.response.status) {
        case 400:
          console.log(await response.json());
          break;

        case 500:
          console.log(await response.json());
          break;

        default:
          break;
      }
});

HttpMockService API

Success Response

// env.production = false

const httpMock = new HttpMockService();
const http: HttpInterfaceService = env.production ? new HttpService() : httpMock;


httpMock.onGet(url, () => {
  return Promise.resolve({
    status: 200,
    response: {
      id: 1,
      name: 'Shena',
      type: 'Dog',
    },
  });
});


http.get<any>({ endpoint: url }).then(async (response: any) => {
      switch (response.status) {
        case 200:
          console.log(await response.json());
          break;

        default:
          break;
      }
});

Error Response

// env.production = false

const httpMock = new HttpMockService();
const http: HttpInterfaceService = env.production ? new HttpService() : httpMock;

  return Promise.reject({
    status: 500,
    response: {
      description: "Internal Server Error"
    },
  });
});


http.get<any>({ endpoint: url }).then(async (response: any) => {
      switch (response.status) {
        case 200:
          console.log(await response.json());
          break;

        default:
          break;
      }
}).catch((error: unknown) => {
    if (error instanceof HttpResponseError) {
       switch (error.response.status) {
        case 400:
          console.log(await response.json());
          break;

        case 500:
          console.log(await response.json());
          break;

        default:
          break;
      }
    } else {
      console.error("An unexpected error occurred:", error);
    }
