Issues with Typescript typechecking in Http post responses are unresolved

This is the Http Call I am working with:

fetchData(): Observable<MyTypedData> {
return this.httpClient.post<MyTypedData>(this._url, httpOptions)
  .pipe(
    catchError(this.handleErrors)
  );

}

The structure of MyTypedData.ts is as follows:

export class MyTypedData {
  id: number;
  name: string;
}

Here is a JSON Response (Incomplete MyTypedData):

{ "id": 123, "status": "active" }

I intentionally created this incomplete JSON response to test something.

Question: Will there be an error thrown by HttpClient due to the incomplete data in the response and trigger the error function for subscribers?

Answer №1

The type system of TypeScript is used solely for compile-time purposes. It influences the way you write your code, but it is not present at runtime. This means that mismatches between JSON data and your class will not result in errors during execution.
