Retrieving data from an Ajax response using Typescript

I encountered the following problem while using this code:

return new Promise(resolve => {
    this.http.get(Config.rootUrl, {
        params
    }).subscribe(response => {
        resolve(response.data);
    }, (err: HttpErrorResponse) => {
        console.log(err.message);
    });
});

My IDE, PhpStorm, is highlighting the line resolve( response.data ); as an error:

property data does not exist on type Object

This error doesn't bother me much usually, but sometimes Angular shows the same issue after compilation.

Can anyone provide insight into what might be causing this problem?

Best regards, Radek

Answer №1

It is recommended to utilize the version of http.get that specifies the type parameter in order to receive a strongly typed object, for example:

export interface MyInterface.....

this.http.get<MyInterface>().subscribe(res => ....)

The variable res will be of the type MyInterface with all the properties you have defined.
