Typescript interface for objects with some known and some unknown property names

Question

I have an object where all the keys are string, some of the values are string and the rest are objects in this form:

var object = {
    \"fixedKey1\": \"some         


        

Answer 1

As @Paleo explained, you can use union property to define an interface for your corresponding object.

I would say you should define an interface for object values and then you should define your original object.

Sample interface can be:

export interface IfcObjectValues {
    param1: number[];
    param2: string;
    param3: string;        
}

export interface IfcMainObject {
 [key : string]: string | IfcObjectValues;
}
