What is the process for setting up an optional interface?

Here's a scenario I'm working with:

interface IRenderComponent {
  urlToHideAt?: string;
  links?: IInternalNavbarLink[];
  currentLink?: IInternalNavbarLink;
}
const renderComponent = ({ urlToHideAt, links, currentLink }: IRenderComponent) => {

It seems to make sense initially. I've made all children optional, but now I am encountering an error whenever I attempt to use the function,

Expected 1 arguments, but got 0.ts(2554)

This error is understandable. I specified the props as optional, not the overall argument.

My inquiry then becomes, how can I make the entire argument

{ urlToHideAt, links, currentLink }
optional? What approach should I take?

Answer №1

To simplify your code, you can leverage the power of default parameters in TypeScript:

const renderComponent = ({ urlToHideAt, links, currentLink }: IRenderComponent = {}) => {}

In this scenario, if the caller does not provide the first parameter, it will automatically default to an empty object {}. As a result, urlToHideAt, links, and currentLink will all be undefined within the function.

Answer №2

While the interface cannot be made optional, you have the ability to assign a default value to the initial argument of `renderComponent` in order to make it optional:

const renderComponent = ({ urlToHideAt, links, currentLink }: IRenderComponent = {}) => {
    // Implement your code here
}
