Mapping fetched JSON data to an existing TypeScript object: A step-by-step guide

Having trouble mapping fetched JSON data from the API to an existing object in TypeScript. Here is my code:

This is my Hero Interface:

export interface Hero {
   id: number;
   name: string;
}

When I console log:

https://i.sstatic.net/BIy7n.png

The result of this.hero is always empty (undefined). Can someone help me solve this issue? PS. I'm new to Angular and TypeScript.

Answer №1

Based on the information provided, it appears that the return type is in array form. Therefore, you may need to retrieve the first element or something similar.

this.character = fetchedCharacter[0];

Answer №2

The API initially returned a list, but the Angular/.ts code was expecting a single object. This mismatch caused issues with data mapping. However, once we modified the GET HTTP REQUEST to return a single object instead of a list, the mapping process began functioning correctly!
