[Feature] Add Fetch Options

[luisaveiro]

Summary

Fetch() API supports the option to provide an object containing any custom settings you need to apply to the request. For more information about the available options, read mdm web docs.

---

Possible implementation

We can have withOption and withOptions methods that accept an individual option or multiple options respectively. We should allow the HTTP Client to accept Fetch() API options.

Method signature

export default class HttpClient {
  private options: { [key: string]: unknown } = {};
  
  /**
   * Create a new Http Client instance.
   *
   * @param {string|undefined} baseUrl
   * @param {object|undefined} options
   */
  constructor(baseUrl?: string, options?: object) {
    this.withOptions(options);
    // code ...
  }
  
  /**
   * Add the given option to the request.
   *
   * @param {string} key
   * @param {unknown} value
   *
   * @returns {this}
   */
  public withOption(key: string, value: unknown): this {
    // code ...
  }
  
  /**
   * Add the given options to the request.
   *
   * @param {object} options
   *
   * @returns {this}
   */
  public withOptions(options: object): this {
    // code ...
  }
}

Code examples

Code example - using withOption

import { HttpClient } from '@wolfpackthatcodes/http-client';

const response = new HttpClient().withOption('credentials', 'same-origin').get('https://api.example.local/users');

Code example - using withOptions

import { HttpClient } from '@wolfpackthatcodes/http-client';

const response = new HttpClient().withOptions({ credentials: 'same-origin' }).get('https://api.example.local/users');

Code example - with constructor

import { HttpClient } from '@wolfpackthatcodes/http-client';

const response = new HttpClient('https://api.example.local/', { credentials: 'same-origin' }).get('/users');
