@ngrok/mantle v0.9.0

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.

Getting Started

Install @ngrok/mantle with your preferred package manager:

Then, add the preset and mantle content to your tailwind configuration.

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;

Next, check out the Overview & Setup and Theme Provider usage docs and start using mantle components in your application!

Prerequisites

The following prerequisites are required to contribute to @ngrok/mantle. We walk through the tooling installation steps below.

• Node 20
• pnpm 9
• nvm

Installation

Install the prerequisites through either the automated or manual installation guides.

Automated Installation

We use direnv to assist you with setting up all of the required tooling. Prefer to install and manage the tooling yourself? See the manual installation instructions below.

First, install direnv:

For all other OSes, see the direnv installation guide.

!NOTE Don't forget to set up direnv integration with your shell.

Next, clone the repo and move into the directory:

git clone git@github.com:ngrok-oss/mantle.git
cd frontend

Next, run:

direnv allow

!WARNING If direnv allow does nothing for you (you should see things happening!), consider following the guides to integrate direnv with your shell and then try direnv allow again! As a last resort, you can follow the manual installation instructions up above.

This will install nvm (if not already installed) as well as set the correct node and pnpm versions for you. It will also run pnpm install at the end to install all node_modules.

Manual Installation

If you prefer to manually manage and install the tooling yourself, follow these steps:

1. Install nvm or your node version manager of choice.
2. Ensure that node 20 is installed. With nvm, run nvm install.
3. Enable pnpm with corepack: corepack enable pnpm
4. Install pnpm with corepack: corepack install
5. Install project dependencies with pnpm: pnpm install
