UI components for Vercel examples

The UI components exported here are being used in many of the examples in this repository. They're built with React, TypeScript, and Tailwind CSS.

How to use

1. Package installation

Install the package with npm, pnpm, or yarn:

npm i @vercel/examples-ui
# or
pnpm i @vercel/examples-ui
# or
yarn add @vercel/examples-ui

The package relies on Tailwind picking up its styles, so if you don't have Tailwind CSS already install it like so:

npm i tailwindcss postcss autoprefixer
# or
pnpm i tailwindcss postcss autoprefixer
# or
yarn add tailwindcss postcss autoprefixer

2. Tailwindcss setup

To allow Tailwind CSS to know which styles to pick up, and to also add our design, Open tailwind.config.js in your app and add the following preset and content path:

module.exports = {
  presets: [require('@vercel/examples-ui/tailwind')],
  content: ['./node_modules/@vercel/examples-ui/**/*.js'],
}

3. PostCSS setup

You'll need to have a postcss.config.js file with:

// If you want to use other PostCSS plugins, see the following:
// https://tailwindcss.com/docs/using-with-preprocessors
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
}

4. Adding global styles

In the App Router

Open any layout or page where you want the global styles to be applied and add the following import:

import '@vercel/examples-ui/globals.css'

In pages

Open pages/_app.tsx and add the following import to include the global CSS of the package and Tailwind base CSS:

import '@vercel/examples-ui/globals.css'

If you don't have a pages/_app.tsx already it should look like this:

import type { AppProps } from 'next/app'
import '@vercel/examples-ui/globals.css'

export default function MyApp({ Component, pageProps }: AppProps) {
  return <Component {...pageProps} />
}

Now, if I wanted to add the default layout used in all examples, I can import the Layout component and use it inside _app.tsx like so:

import type { AppProps } from 'next/app'
import type { LayoutProps } from '@vercel/examples-ui/layout'
import { getLayout } from '@vercel/examples-ui'
import '@vercel/examples-ui/globals.css'

export default function MyApp({ Component, pageProps }: AppProps) {
  const Layout = getLayout<LayoutProps>(Component)

  return (
    <Layout
      title="API Rate Limiting with Upstash"
      path="edge-middleware/api-rate-limit-upstash"
    >
      <Component {...pageProps} />
    </Layout>
  )
}

Contributing

Install packages from the root of the repo:

pnpm build

To watch for changes, navigate to this folder in your terminal and run:

pnpm build:swc -w

If you want to make an update to the package, go to an example and install it with npm:

npm i $(npm pack ../../internal/packages/ui | tail -1)

Make sure to have dependencies installed in internal/packages/ui or otherwise the symlink won't resolve imports.
