aether-setup

iOS Only

This library targets iOS exclusively. Android and web are not supported.

Prerequisites

• Expo project with TypeScript
• React Native ≥ 0.72

Note: Commands below use npx expo install for React Native and Expo packages and pnpm for everything else.

Step 1: Install dependencies

npx expo install nativewind@^4 react-native-reanimated react-native-safe-area-context @expo-google-fonts/inter @callstack/liquid-glass expo-haptics expo-linear-gradient
pnpm add @byarcadia-app/aether
pnpm add -D tailwindcss@^3.4.17

Optional — only needed for IconSymbol (SF Symbols on iOS):

npx expo install expo-symbols

Step 2: Configure Tailwind

Create tailwind.config.js:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{js,jsx,ts,tsx}",
    "./node_modules/@byarcadia-app/aether/dist/**/*.{js,mjs}",
  ],
  presets: [require("nativewind/preset"), require("@byarcadia-app/aether/tailwind-preset").preset],
  theme: {
    extend: {},
  },
  plugins: [],
};

Step 3: Create global CSS

Create global.css:

@tailwind base;
@tailwind components;
@tailwind utilities;

Step 4: Configure Babel

Create or update babel.config.js:

module.exports = function (api) {
  api.cache(true);
  return {
    presets: [["babel-preset-expo", { jsxImportSource: "nativewind" }], "nativewind/babel"],
  };
};

Step 5: Configure Metro

Create or update metro.config.js:

const { getDefaultConfig } = require("expo/metro-config");
const { withNativeWind } = require("nativewind/metro");

const config = getDefaultConfig(__dirname);

module.exports = withNativeWind(config, { input: "./global.css" });

Step 6: Import CSS in root layout

Add to your root layout file (e.g., app/_layout.tsx):

import "./global.css";

Step 7: TypeScript

Create nativewind-env.d.ts:

/// <reference types="nativewind/types" />

Quick Start

Wire up AetherProvider with fonts and React Navigation:

import { AetherProvider, useInterFonts, useNavigationTheme } from "@byarcadia-app/aether";
import { ThemeProvider } from "@react-navigation/native";
import { Stack } from "expo-router";
import * as SplashScreen from "expo-splash-screen";
import { useEffect } from "react";

import "./global.css";

SplashScreen.preventAutoHideAsync();

export default function RootLayout() {
  const { fontsLoaded, fontError } = useInterFonts();
  const navigationTheme = useNavigationTheme();

  useEffect(() => {
    if (fontsLoaded || fontError) {
      SplashScreen.hideAsync();
    }
  }, [fontsLoaded, fontError]);

  if (!fontsLoaded && !fontError) {
    return null;
  }

  return (
    <AetherProvider>
      <ThemeProvider value={navigationTheme}>
        <Stack />
      </ThemeProvider>
    </AetherProvider>
  );
}

Peer Dependencies

• @callstack/liquid-glass >=0.7
• @expo-google-fonts/inter >=0.4.2
• expo-haptics >=14
• expo-linear-gradient >=14
• expo-symbols >=1 (optional — only for IconSymbol)
• nativewind >=4
• react >=18
• react-native >=0.72
• react-native-reanimated >=3
• tailwindcss ^3.3.5

Verification

After setup, run npx expo start and verify the app compiles. Themed components should render with the correct Inter font and color tokens in both light and dark mode.
