When using Angular with WebApi, it is important to decide whether the models' first letter should be

Completely new to working with Angular and I'm encountering an issue where the first letter of my result from the Webapi model is always uppercase, even though my Angular model's first letter is lowercase.

User.ts

    export interface User extends ICommon {
        id: string;
        firstName: string;
        lastName: string;
    }

User.service.ts

     public getActiveUsers(): Observable<User[]> {
      return this.http
       .get<User[]>(baseUrl + "user/GetUserlist");

}

The console output displays:

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

User.component.html

    {{user.firstName}}  => shows no result
    {{user.FirstName}}  => shows the correct result

User.component.ts

    let result = this.user.firstName => undefined
    let result = this.user.FirstName => compile time error.

I'm feeling confused about what I might be doing wrong here. Any insights?

Answer №1

The reason for this issue is due to the server using PascalCasing, while you have defined an interface that does not align with the data returned by the server.

To resolve this problem, update your interface to:

export interface User extends ICommon {
        Id: string;
        FirstName: string;
        LastName: string;
}

Then, access the data like so:

let result = this.user.FirstName  

If you are working with a WebApi backend, the default Json serialization keeps the fields in their original C# casing.
