Properties Type — svelte Architecture

Source Code

packages/svelte/types/index.d.ts lines 28–36

	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 }
			: {});
