Next.js Guide

How to set up Tamagui with Next.js

Running npm create tamagui@latest let's you choose the starter-free starter which is a very nicely configured Next.js app where you can take or leave whatever you want.

Create a new Next.js project


yarn dlx create-next-app@latest

If you are using Turbopack, we have a section for optimization at the end of this document. If you aren't, then you may want the optional @tamagui/next-plugin which helps smooth out a few settings. We'll show how to configure it for both pages and app router in this guide. See the compiler install docs for more options.

Add @tamagui/next-plugin to your project:


yarn add @tamagui/next-plugin

We recommend starting with our default config which gives you media queries and other nice things:

tamagui.config.ts
import { defaultConfig } from '@tamagui/config/v4'
import { createTamagui } from 'tamagui' // or '@tamagui/core'

const appConfig = createTamagui(defaultConfig)

export type AppConfig = typeof appConfig

declare module 'tamagui' {
  // or '@tamagui/core'
  // overrides TamaguiCustomConfig so your custom types
  // work everywhere you import `tamagui`
  interface TamaguiCustomConfig extends AppConfig {}
}

export default appConfig

From here, choose your Next.js routing option to continue:

Pages router

Automatically generate routes based on the filenames.

App router

Allows more complex patterns and setups.

Turbopack

next.config.js

Set up the optional Tamagui plugin to next.config.js:

next.config.js
const { withTamagui } = require('@tamagui/next-plugin')

module.exports = function (name, { defaultConfig }) {
  let config = {
    ...defaultConfig,
    // ...your configuration
  }
  const tamaguiPlugin = withTamagui({
    config: './tamagui.config.ts',
    components: ['tamagui'],
  })
  return {
    ...config,
    ...tamaguiPlugin(config),
  }
}

pages/_document.tsx

If you're using React Native Web components, you'll want to gather the react-native-web styles in _document:

_document.tsx
import NextDocument, {
  DocumentContext,
  Head,
  Html,
  Main,
  NextScript,
} from 'next/document'
import { StyleSheet } from 'react-native'

export default class Document extends NextDocument {
  static async getInitialProps({ renderPage }: DocumentContext) {
    const page = await renderPage()

    // @ts-ignore RN doesn't have this type
    const rnwStyle = StyleSheet.getSheet()

    return {
      ...page,
      styles: (
        <style
          id={rnwStyle.id}
          dangerouslySetInnerHTML={{ __html: rnwStyle.textContent }}
        />
      ),
    }
  }
  render() {
    return (
      <Html lang="en">
        <Head>
          <meta id="theme-color" name="theme-color" />
          <meta name="color-scheme" content="light dark" />
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    )
  }
}

Tamagui automatically injects styles at runtime. You can optionally generate a static CSS file - see the Static CSS Output section.

pages/_app.tsx

Add TamaguiProvider:

_app.tsx
import { NextThemeProvider } from '@tamagui/next-theme'
import { AppProps } from 'next/app'
import Head from 'next/head'
import React, { useMemo } from 'react'
import { TamaguiProvider } from 'tamagui'
import tamaguiConfig from '../tamagui.config'

export default function App({ Component, pageProps }: AppProps) {
  // memo to avoid re-render on dark/light change
  const contents = useMemo(() => {
    return <Component {...pageProps} />
  }, [pageProps])

  return (
    <>
      <Head>
        <title>Your page title</title>
        <meta name="description" content="Your page description" />
        <link rel="icon" href="/favicon.ico" />
      </Head>
      <NextThemeProvider>
        <TamaguiProvider
            config={tamaguiConfig}
            disableInjectCSS
            disableRootThemeClass
          >
          {contents}
        </TamaguiProvider>
      </NextThemeProvider>
    </>
  )
}

Use disableInjectCSS for SSR apps to prevent duplicate style injection. Only omit it for client-only apps without server rendering.

Themes

We've created a package that works with Tamagui to properly support SSR light/dark themes that also respect user system preference, called @tamagui/next-theme. It assumes your light/dark themes are named as such, but you can override it. This is pre-configured in the create-tamagui starter.


yarn add @tamagui/next-theme

Here's how you'd set up your _app.tsx:

_app.tsx
import { NextThemeProvider, useRootTheme } from '@tamagui/next-theme'
import { AppProps } from 'next/app'
import Head from 'next/head'
import React, { useMemo } from 'react'
import { TamaguiProvider, createTamagui } from 'tamagui'

// you usually export this from a tamagui.config.ts file:
import { defaultConfig } from '@tamagui/config/v4'
const tamaguiConfig = createTamagui(defaultConfig)

// make TypeScript type everything based on your config
type Conf = typeof tamaguiConfig
declare module '@tamagui/core' {
  interface TamaguiCustomConfig extends Conf {}
}

export default function App({ Component, pageProps }: AppProps) {
  const [theme, setTheme] = useRootTheme()

  // memo to avoid re-render on dark/light change
  const contents = useMemo(() => {
    return <Component {...pageProps} />
  }, [pageProps])

  return (
    <>
      <Head>
        <title>Your page title</title>
        <meta name="description" content="Your page description" />
        <link rel="icon" href="/favicon.ico" />
      </Head>
      <NextThemeProvider
        // change default theme (system) here:
        // defaultTheme="light"
        onChangeTheme={setTheme as any}
      >
        <TamaguiProvider
          config={tamaguiConfig}
          disableInjectCSS
          disableRootThemeClass
          defaultTheme={theme}
        >
          {contents}
        </TamaguiProvider>
      </NextThemeProvider>
    </>
  )
}

Static CSS Output

You can generate a static CSS file for your themes and tokens. There are two ways to do this:

Option 1: Using the CLI

The simplest approach is to use the Tamagui CLI to generate the CSS file:


yarn dlx tamagui generate

This outputs CSS to .tamagui/tamagui.css. Copy it to your public folder or configure outputCSS in your tamagui.build.ts:

tamagui.build.ts
import type { TamaguiBuildOptions } from '@tamagui/core'

export default {
  components: ['tamagui'],
  config: './tamagui.config.ts',
  outputCSS: './public/tamagui.css',
} satisfies TamaguiBuildOptions

Then import it in your _app.tsx:

_app.tsx
import '../public/tamagui.css'

Option 2: Using the Next.js Plugin

You can also have the plugin generate CSS during your Next.js build:

next.config.js
const tamaguiPlugin = withTamagui({
  config: './tamagui.config.ts',
  components: ['tamagui'],
  outputCSS:
    process.env.NODE_ENV === 'production' ? './public/tamagui.css' : null,
  // faster dev mode, keeps debugging helpers:
  disableExtraction: process.env.NODE_ENV === 'development',
})

Then import it in your _app.tsx:

_app.tsx
import '../public/tamagui.css'

With outputCSS, you don't need getCSS() in your _document.tsx - all styles are handled by the static CSS file and runtime style injection.

Font loading

To ensure font loads globally, add a global style to styles in _document_.tsx:

NextTamaguiProvider.tsx
<style jsx global>{`
  html {
    font-family: 'Inter';
  }
`}</style>

App router

Tamagui includes Server Components support for the Next.js app directory with use client support.

Note that "use client" does render on the server, and since Tamagui extracts to CSS statically and uses inline <style /> tags for non-static styling, we get excellent performance as-is.

next.config.js

The Tamagui plugin is optional but helps with compatibility with the rest of the React Native ecosystem. It requires CommonJS for now as the optimizing compiler makes use of a variety of resolving features that haven't been ported to ESM yet. Be sure to rename your next.config.mjs to next.config.js before adding it:

next.config.js
const { withTamagui } = require('@tamagui/next-plugin')

module.exports = function (name, { defaultConfig }) {
  let config = {
    ...defaultConfig,
    // ...your configuration
  }

  const tamaguiPlugin = withTamagui({
    config: './tamagui.config.ts',
    components: ['tamagui'],
    appDir: true,
  })

  return {
    ...config,
    ...tamaguiPlugin(config),
  }
}

You need to pass the appDir boolean to @tamagui/next-plugin.

app/layout.tsx

Create a new component to add TamaguiProvider:

The internal usage of next/head is not supported in the app directory, so you need to add the skipNextHead prop to your <NextThemeProvider>.

NextTamaguiProvider.tsx
'use client'

import { ReactNode } from 'react'
import { StyleSheet } from 'react-native'
import { useServerInsertedHTML } from 'next/navigation'
import { NextThemeProvider } from '@tamagui/next-theme'
import { TamaguiProvider } from 'tamagui'
import tamaguiConfig from '../tamagui.config'

export const NextTamaguiProvider = ({ children }: { children: ReactNode }) => {
  // only if using react-native-web components like ScrollView:
  useServerInsertedHTML(() => {
    // @ts-ignore
    const rnwStyle = StyleSheet.getSheet()
    return (
      <>
        <style
          dangerouslySetInnerHTML={{ __html: rnwStyle.textContent }}
          id={rnwStyle.id}
        />
      </>
    )
  })

  return (
    <NextThemeProvider skipNextHead>
      <TamaguiProvider config={tamaguiConfig} disableRootThemeClass>
        {children}
      </TamaguiProvider>
    </NextThemeProvider>
  )
}

The getNewCSS helper in Tamagui will keep track of the last call and only return new styles generated since the last usage.

Then add it to your app/layout.tsx:

layout.tsx
import { Metadata } from 'next'
import { NextTamaguiProvider } from './NextTamaguiProvider'

export const metadata: Metadata = {
  title: 'Your page title',
  description: 'Your page description',
  icons: '/favicon.ico',
}

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>
        <NextTamaguiProvider>{children}</NextTamaguiProvider>
      </body>
    </html>
  )
}

You can use suppressHydrationWarning to avoid the warning about mismatched content during hydration in dev mode.

app/page.tsx

Now you're ready to start adding components to app/page.tsx:

page.tsx
'use client'

import { Button } from 'tamagui'

export default function Home() {
  return <Button>Hello world!</Button>
}

Themes


yarn add @tamagui/next-theme

Here's how you'd set up your NextTamaguiProvider.tsx:

NextTamaguiProvider.tsx
'use client'

import '@tamagui/font-inter/css/400.css'
import '@tamagui/font-inter/css/700.css'

import { ReactNode } from 'react'
import { StyleSheet } from 'react-native'
import { useServerInsertedHTML } from 'next/navigation'
import { NextThemeProvider, useRootTheme } from '@tamagui/next-theme'
import { TamaguiProvider } from 'tamagui'
import tamaguiConfig from '../tamagui.config'

export const NextTamaguiProvider = ({ children }: { children: ReactNode }) => {
  const [theme, setTheme] = useRootTheme()

  // only needed if using react-native-web components:
  useServerInsertedHTML(() => {
    // @ts-ignore
    const rnwStyle = StyleSheet.getSheet()
    return (
      <style
        dangerouslySetInnerHTML={{ __html: rnwStyle.textContent }}
        id={rnwStyle.id}
      />
    )
  })

  return (
    <NextThemeProvider
      skipNextHead
      // change default theme (system) here:
      // defaultTheme="light"
      onChangeTheme={(next) => {
        setTheme(next as any)
      }}
    >
      <TamaguiProvider
        config={tamaguiConfig}
        disableRootThemeClass
        defaultTheme={theme}
      >
        {children}
      </TamaguiProvider>
    </NextThemeProvider>
  )
}

Static CSS Output

You can generate a static CSS file for your themes and tokens. Use either the CLI or the Next.js plugin:

next.config.js
const tamaguiPlugin = withTamagui({
  config: './tamagui.config.ts',
  components: ['tamagui'],
  outputCSS:
    process.env.NODE_ENV === 'production' ? './public/tamagui.css' : null,
  // faster dev mode, keeps debugging helpers:
  disableExtraction: process.env.NODE_ENV === 'development',
})

Then link the generated CSS file in your app/layout.tsx:

app/layout.tsx
import '../public/tamagui.css'

With React 19, Tamagui automatically injects runtime styles via style tags on the server. The outputCSS file handles themes and tokens generated at build time, so you don't need any getCSS() calls in your provider.

Font loading

To ensure font loads globally, add a global style to useServerInsertedHTML in NextTamaguiProvider.tsx:

NextTamaguiProvider.tsx
<style jsx global>{`
  html {
    font-family: 'Inter';
  }
`}</style>

NextThemeProvider

The NextThemeProvider is a provider that allows you to set the theme for your app. It also provides a hook to access the current theme and a function to change the theme.

Props

skipNextHead

boolean

Required in app router. The internal usage of next/head is not supported in the app directory, so you need to add it.

enableSystem

boolean

Whether to switch between dark and light themes based on prefers-color-scheme.

defaultTheme

string

If enableSystem is `false`, the default theme is light. Default theme name (for v0.0.12 and lower the default was light).

forcedTheme

string

Forced theme name for the current page.

onChangeTheme

(name: string) => void

Used to change the current theme. The function receives the theme name as a parameter.

systemTheme

string

System theme name for the current page.

enableColorScheme

boolean

Whether to indicate to browsers which color scheme is used (dark or light) for built-in UI like inputs and buttons.

disableTransitionOnChange

boolean

Disable all CSS transitions when switching themes.

storageKey

string

Key used to store theme setting in localStorage.

themes

string[]

List of all available theme names.

value

ValueObject

Mapping of theme name to HTML attribute value. Object where key is the theme name and value is the attribute value.

Theme toggle

If you need to access the current theme, say for a toggle button, you will then use the useThemeSetting hook. We'll release an update in the future that makes this automatically work better with Tamagui's built-in useThemeSetting.

SwitchThemeButton.tsx
import { useState } from 'react'
import { Button, useIsomorphicLayoutEffect } from 'tamagui'
import { useThemeSetting, useRootTheme } from '@tamagui/next-theme'

export const SwitchThemeButton = () => {
  const themeSetting = useThemeSetting()
  const [theme] = useRootTheme()

  const [clientTheme, setClientTheme] = useState<string | undefined>('light')

  useIsomorphicLayoutEffect(() => {
    setClientTheme(themeSetting.forcedTheme || themeSetting.current || theme)
  }, [themeSetting.current, themeSetting.resolvedTheme])

  return (
    <Button onPress={themeSetting.toggle}>Change theme: {clientTheme}</Button>
  )
}

Turbopack

Turbopack doesn't support Webpack plugins, so you'll use the Tamagui CLI to optimize your build. In dev mode, Tamagui works without any setup.

Setup

Install the CLI:


yarn add -D @tamagui/cli

Create tamagui.build.ts:

tamagui.build.ts
import type { TamaguiBuildOptions } from '@tamagui/core'

export default {
  components: ['@tamagui/core'], // or ['tamagui']
  config: './tamagui.config.ts',
  outputCSS: './public/tamagui.css',
} satisfies TamaguiBuildOptions

Your next.config.js can be empty:

next.config.js
module.exports = {}

Build Scripts

The CLI can wrap your build command, optimizing files beforehand and restoring them after:

package.json
{
  "scripts": {
    "dev": "next dev --turbopack",
    "build": "tamagui build --target web ./src -- next build"
  }
}

The -- separator tells the CLI to run next build after optimization, then restore your source files automatically.

CSS Setup

The CLI generates theme CSS to outputCSS. Commit this file to git and import it in your layout:

app/layout.tsx
import '../public/tamagui.css'
import { TamaguiProvider } from '@tamagui/core'
import config from '../tamagui.config'

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>
        <TamaguiProvider config={config}>{children}</TamaguiProvider>
      </body>
    </html>
  )
}

With React 19, Tamagui automatically injects runtime styles via style tags. The outputCSS file handles themes and tokens that are generated at build time.

Run npx tamagui build once to generate the initial CSS file, then commit it.

CI Verification

Use --expect-optimizations to fail builds if the compiler optimizes fewer than the expected minimum number of components:

{
  "build": "tamagui build --target web --expect-optimizations 5 ./src -- next build"
}

This will fail the build if fewer than 5 components are optimized, helping catch configuration issues in CI.
