How can we convert ActiveRecord objects to TypeScript types for repositories that are not mono?

edit

One way to convert ActiveRecord objects to TypeScript types for repositories that are not mono is to define interfaces that correspond to the columns of the Active Record models. For example, if we have an ActiveRecord model named "User" with columns "id", "name", and "email", we can define an interface in TypeScript with the same properties:

interface User {
  id: number;
  name: string;
  email: string;
}

Then, we can use this interface as the type for any variables or functions that deal with User objects. For example, if we have a function that returns an array of User objects, its signature would look like this:

function getUsers(): User[] {
  // ...
}

We can also use this interface as the type for any JSON objects that we receive from an external API. If we receive a JSON object that represents a User, we can cast it to the User interface using TypeScript's casting syntax:

const userJson = '{"id": 123, "name": "John Doe", "email": "john.doe@example.com"}';
const user = JSON.parse(userJson) as User;

Using interfaces like this can help us maintain type safety and catch errors at compile time, even when working with external data sources.
