What is the best way to use the promise interface in TypeScript?

export interface VehicleElement {
   truck: Promise<Int32Array>;
}

issue: The class "VehicleResult" fails to properly implement interface "Promise".
Type "VehicleResult" is lacking the necessary properties from type "Promise": then, catch, finally, [Symbol.toStringTag] ts(2420)

class VehicleResult implements Promise<VehicleElement>{
   truck:Int32Array = new Int32Array;
}

What steps should I take to resolve this issue?

Answer №1

You cannot implement a Promise directly within a class. If you are looking to return a promise, it should be done through a method defined in the class. Here is an example:

class CarResult {
   bus:Int32Array = new Int32Array;

   async CarElement(): Promise<CarElement> {
    return Promise.resolve(
     // CarElement
    )
   }
}
