What is the method to define a loosely typed object literal in a TypeScript declaration?

We are currently in the process of creating TypeScript definitions for a library called args-js, which is designed to parse query strings and provide the results in an object literal format. For example:

?name=miriam&age=26

This input will produce the following output:

{
  name: "miriam",
  age: 26
}

The challenge we are facing is that the property names cannot be declared in advance for the return value, leading us to consider using a different approach instead of specifying a return value as any.

Answer №1

When working with objects that have a consistent depth of 1, you can define the type like this:

{[key: string]: string | boolean | number}
