simple Resource class before normalization

PostResource.ts

class PostResource {
  readonly id: number | null = null;
  readonly title: string = '';
  readonly body: string = '';
  
  constructor(args) {
    Object.assign(this, args);
  }
  
  static async fetchDetail({ id }: { id: string }): PostResource {
    const options = {
      method: 'GET',
      credentials: 'same-origin',
      headers: {
        'Content-Type': 'application/json',
      },
    };
    const url = `/post/${id}`;
    const response = await (await fetch(url, options)).json();
    return new PostResource(response);
  }
}
