Install the Compiler

For more background read the Compiler About page, for performance see Benchmarks.

It's important to note the compiler is optional, and it's much easier to get started by building your app out before you commit to the setup cost.

The compiler generates built versions of your components and config into a .tamagui directory. You'll want to add that directory to your .gitignore.

yarn add tamagui-loader

We have a full example of a plain Webpack or Vite setup in the simple starter accessible through npm create tamagui@latest, which shows a complete configuration with more detail.

Add tamagui-loader and set up your webpack.config.js.

You can set it up more manually like so:

const { shouldExclude } = require('tamagui-loader')

const tamaguiOptions = {
  config: './tamagui.config.ts',
  components: ['tamagui'],
  importsWhitelist: ['constants.js', 'colors.js'],
  logTimings: true,
  disableExtraction: process.env.NODE_ENV === 'development',
  // optional advanced optimization of styled() definitions within your app itself, not just ones in your `components` option
  // default is false
  enableDynamicEvaluation: false,
}

const projectRoot = __dirname

module.exports = {
  resolve: {
    alias: {
      // Resolve react-native to react-native-web
      'react-native$': require.resolve('react-native-web'),
      // optional, for lighter svg icons on web
      'react-native-svg': require.resolve('@tamagui/react-native-svg'),
    }
  },
  module: {
    rules: [
      {
        test: /\.[jt]sx?$/,
        // you'll likely want to adjust this helper function,
        // but it serves as a decent start that you can copy/paste from
        exclude: path => shouldExclude(path, projectRoot, tamaguiOptions),
        use: [
          // optionally thread-loader for significantly faster compile!
          'thread-loader',

          // works nicely alongside esbuild
          {
            loader: 'esbuild-loader',
          },

          {
            loader: 'tamagui-loader',
            options: tamaguiOptions,
          },
        ]
      }
    ]
  },
}

Or you can use the TamaguiPlugin which automates some of this setup for you:

const { TamaguiPlugin } = require('tamagui-loader')

module.exports = {
  plugins: [
    new TamaguiPlugin({
      config: './tamagui.config.ts',
      components: ['tamagui'],
      importsWhitelist: ['constants.js', 'colors.js'],
      logTimings: true,
      disableExtraction: process.env.NODE_ENV === 'development',
    }),
  ],

Some notes on the options:

• importsWhitelist: Tamagui takes a conservative approach to partial evaluation, this field whitelists (matching against both .ts and .js) files to allow files that import them to read and use their values during compilation. Typically colors and constants files.
• disableExtraction: Useful for faster developer iteration as your design system hot reloads more reliably.

See the Vite guide for more complete setup.

Add @tamagui/vite-plugin and update your vite.config.ts:

import { tamaguiExtractPlugin, tamaguiPlugin } from '@tamagui/vite-plugin'

export default defineConfig({
  plugins: [
    tamaguiPlugin({
      config: './src/tamagui.config.ts',
      components: ['tamagui'],
    }),
    // optional, adds the optimizing compiler:
    tamaguiExtractPlugin(tamaguiConfig),
  ],
})

See the (guide) for more complete setup.

Add @tamagui/next-plugin and configure your next.config.js. Here we show a fuller scope of the options

// note next-compose-plugins somewhat unmaintained
// you can use a simple two-liner instead, see:
// https://github.com/cyrilwanner/next-compose-plugins/issues/59#issuecomment-1192523231
const withPlugins = require('next-compose-plugins')
const { withTamagui } = require('@tamagui/next-plugin')

export default withPlugins([
  withTamagui({
    config: './tamagui.config.ts',
    components: ['tamagui'],

    // rest are all optional:

    // disable static extraction, faster to iterate in dev mode (default false)
    disableExtraction: process.env.NODE_ENV === 'development',

    // Exclude react-native-web modules to lighten bundle
    excludeReactNativeWebExports: ['Switch', 'ProgressBar', 'Picker'],

    // By default, we configure webpack to pass anything inside your root or design system
    // to the Tamagui loader. If you are importing files from an external package, use this:
    shouldExtract: (path: string, projectRoot: string) => {
      if (path.includes('../packages/myapp')) {
        return true
      }
    },

    // Advanced:

    // Watches a file that uses @tamagui/theme-builder
    // See the "Creating Themes" guide
    themeBuilder: {
      input: './themes-input.tsx',
      output: './themes.tsx',
    },

    // adds mini-css-extract and css-minimizer-plugin, can fix issues with unique configurations
    enableCSSOptimizations: false,
    // disable tamagui config to make fonts easier to import
    disableFontSupport: false,

    // Many packages give difficulty to the nextjs server-side (node) runtime when un-bundled.
    // for example, tamagui configures aliases like `react-native` => `react-native-web`.
    // if you're running into a module that has errors importing react-native, you'll want to
    // use a custom shouldExcludeFromServer function to include it (or override the default).
    // this is the exact same return type as webpack.externals.
    // returning undefined will let tamagui handle it, boolean or other values to override.
    shouldExcludeFromServer: ({ fullPath, request }) => {
      if (fullPath.includes('my-module')) {
        return `commonjs ${commonjs}`
      }
      if (request === 'some-hard-to-bundle-package') {
        return true
      }
    },
  })
])

Note: If running into issues, the environment variable IGNORE_TS_CONFIG_PATHS to "true" can fix issues with Tamagui being resolved incorrectly.

See the Next.js Guide for more details on setting up your app.

Babel / Metro

Note that the @tamagui/babel-plugin is completely optional, and on native Tamagui doesn't optimize as much as on web, so leaving it out is actually recommended to start. If later on you feel the need for a bit more speed, you can try adding it.

yarn add @tamagui/babel-plugin

Add to your babel.config.js:

module.exports = {
  plugins: [
    [
      '@tamagui/babel-plugin',
      {
        components: ['tamagui'],
        config: './tamagui.config.ts',
        importsWhitelist: ['constants.js', 'colors.js'],
        logTimings: true,
        disableExtraction: process.env.NODE_ENV === 'development',
      }
    ],
  ]
}

Currently the native compiler doesn't optimize as much as it could. It bails out if it encounters any theme usage, like <View backgroundColor="$background" />. If you are on version 1.75 or greater, you can test enabling this experimental optimization by adding a new property with the key experimentalFlattenThemesOnNative set to true in the above config object and that will make the compiler to flat and extract any theme usage or dynamic values.

Expo

Check out the Expo guide for more information on setting up Expo.

If you want autocompleted imports of react-native without having to install all the weight of react-native, you can set react-native version to 0.0.0, and add @types/react-native at the latest version.

All compiler plugins accept the same options:

By default the Tamagui compiler only optimizes styled expressions found in the modules defined by your components config. This means if you do an inline styled() inside your actual app directory, it will default to runtime style insertion.

This is typically Good Enough™️. As long as you define most of your common components there, you'll get a very high hit rate of compiled styles being used and runtime generation being skipped, as atomic styles with your design system tokens will be mostly pre-generated.

Tamagui has experimental support for loading any component, even if it occurs somewhere outside your configured components modules. This is called "dynamic loading", for now. You can enable it with the setting enableDynamicEvaluation as seen above in the props table.

The way it works is, when the compiler detects a styled() expression outside one of the defined component directories, it will run the following:

1. First, read the file and use a custom babel transform to force all top-level variables to be exported.
2. Then, run esbuild and bundle the entire file to a temporary file in the same directory, something like .tamagui-dynamic-eval-ComponentName.js
3. Now, read the file in and load all new definitions found.
4. Finally, continue with optimization, using the newly optimized component.

You may see why this is experimental. It's very convenient as a developer, but has a variety of edge cases that can be confusing or breaking, and we want to avoid installation woes. Though it does continue on error and work generally, it outputs warnings in Webpack currently due to our plugin not properly indicating to Webpack about the new files (a fixable bug), which causes big yellow warning output and a cache de-opt.

We're leaving this feature under the environment variable while it matures. Let us know if you find it useful.

You can disable the compiler optimizations for an entire file with a comment at the top of your file:

// tamagui-ignore

You can disable the compiler optimization for a single component with the boolean property disableOptimization:

import { View } from '@tamagui/core'

export default () => (
  <View disableOptimization />
)
