Properties Type — svelte Architecture

Source Code

packages/svelte/src/index.d.ts lines 29–37

type Properties<Props, Slots> = Props &
	(Slots extends { default: any }
		? // This is unfortunate because it means "accepts no props" turns into "accepts any prop"
			// but the alternative is non-fixable type errors because of the way TypeScript index
			// signatures work (they will always take precedence and make an impossible-to-satisfy children type).
			Props extends Record<string, never>
			? any
			: { children?: any }
		: {});
