Mantle is ngrok’s UI library and design system. It’s inspired by shadcn/ui and uses Radix with Tailwind for styling. It’s documented using Remix.

import { createRequire } from "node:module";
import { mantlePreset, resolveMantleContentGlob } from "@ngrok/mantle/tailwind-preset";
import type { Config } from "tailwindcss";

const require = createRequire(import.meta.url);

export default {
	presets: [mantlePreset],
	content: [resolveMantleContentGlob(require), "./app/**/*.tsx"], // 👈 don't forget to swap out app content glob here!
	// ... the rest of your tailwind config!
} satisfies Config;
