Export Config interface from ziggy

[apademide]

Description

In the context of an Inertia app, the Ziggy object is passed through the props under $props.ziggy. I could determine it is of the same format as the Config interface, which is not exposed. I found a way to extract the interface like that:

type ZiggyConfig = NonNullable<
  Parameters<typeof import("ziggy-js").useRoute>[0]
>;

which is pretty messy for such a simple type.

It would also not make sense to copy the type in my own codebase directly.

Suggestion

It'd be convenient to simply export the interface from Ziggy, export interface Config { ... }

Where/how would you use that interface?

I extend Inertia PageProps to include props "globally reserved". This way, It's more convenient to work with the app as we know some props exists, and can't be used for anything else — and ziggy is one of them as it's set for all requests automatically.

import type { PageProps as InertiaPageProps } from "@inertiajs/core";

type ZiggyConfig = NonNullable<
  Parameters<typeof import("ziggy-js").useRoute>[0]
>;

/** Props that are standard across all pages. They might not be present in all pages, but must never be used as page-specific props holding different data. */
interface SharedPageProps {
  title?: string;
  ziggy?: ZiggyConfig;
  flash?: unknown;
  
  // ... rest of my global props
}

export type PageProps<T = {}> = InertiaPageProps & SharedPageProps & T;
