How to write an interface for an array with objects?

Question

typescript

I have a variable activatedPackages , which contains an array containing objects containing key-value pairs (mandatory and optional fields), where the value is always a string:

const activatedPackages = [
  {
    // обязательные поля
    id: 123, // число
    activated: true, // булевое
    name: '30 days', // строка
    // необязательные поля (несколько)
    type: 'blablabla' // any
  },
  {
    // обязательные поля
    id: 123, // число
    activated: true, // булевое
    name: '30 days', // строка
    // необязательные поля
    type: 'blablabla' // any
  },
];

The number of objects inside the array can be different. We need to write an interface for the activatedPackages variable .

PS I know, I want a lot, but I just can't figure out how to write such an interface. If you need to do several interfaces, then ok. The main thing is that it works)

Answer 1

interface IActivatedPackages {
    id: number;
    activated: boolean;
    name: string;
    // необязательные поля (несколько)
    n1?: string;
    n2?: string;
    n3?: string;
    n4?: string;
    // warn
    type: any;
}

Um.. on ?
