Navigating the complexities of extracting and storing a data type from a collection of objects

Dealing with a messy API that returns inconsistent values is quite challenging. Instead of manually creating types for each entry, I am looking for a way to infer the types programmatically.

One approach could be by analyzing an array like this:

const array = [
  {
    title: "test",
    name: "Katy Smith",
  },
  {
    title: ["ACNM", "AAF3"],
    name: "Mary Williams,
  },
  {
    title: "test2",
    name: { firstName: "John", lastName: "Doe" },
  },
];

The goal is to automatically infer the type using TypeScript or similar tools, resulting in something like this:

{
title: string | string[],
name: string | {firstName: string, lastName: string}
}

My next step would be to save this inferred type and reuse it in my project, but unfortunately, TypeScript does not exist at runtime making this impossible.

Are there any alternate approaches to achieve this?

Answer №1

The question wasn't fully clear to me, but I have suggested a way to utilize one class for all types. However, based on your recent comment, it seems like this may not be the solution you are seeking.
