Our Angular service interacts with the backend to retrieve data and display it on the UI.
export interface UserDataResponse { id: number; userName: string; }
AngularService_Method1() {
return this.http.get<UserDataResponse[]>(this.appUrl + "/Application/Users")
}
The AngularService_Method1() in the Service layer fetches data from the Backend Users API. The response is known, so we typecast it as UserDataResponse[].
In the Angular Component, I can easily work with the Response's UserDataResponse[] and leverage IntelliSense for the id & userName properties.
We also have another method in the Service layer called AngularService_Method2(), which returns an array of objects.
AngularService_Method2(someParameter:String) {
return this.http.get<any[]>(this.appUrl + "/Application/someendpoint/" + someParameter)
}
The response for this method can be of any type, such as:
For Example - Response 1[{"Id": 1,"Name": "Abc1","City": "Xyz1"},{"Id": 1,"Name": "Abc1","City": "Xyz1"}]
[{"EmployeeId": 100,"Email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="06767774467677742865696b">[email protected]</a>","Rank": "aa1"},{"EmployeeId": 101,"Email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="e59d9c9fa5959497cb868a88">[email protected]</a>","Rank": "aa2"}]
The challenge is how to cast Any[] to CustomType to enable IntelliSense for accessing Properties in Angular/Typescript.
When receiving Response 1, I should be able to access the Id, Name, City properties using IntelliSense in my Angular Component.
