React Native Expo: Building Production-Ready Mobile Apps in 2026

Expo has become the standard for React Native development, providing a managed workflow that handles native configuration, builds, and deployment.

Project Setup with Expo

npx create-expo-app MyApp -t tabs
cd MyApp
npx expo install expo-router expo-linking expo-constants expo-status-bar

EAS Build for Production

// eas.json
{
  "build": {
    "production": {
      "autoIncrement": true,
      "env": { "API_URL": "https://api.production.com" }
    },
    "preview": { "distribution": "internal" }
  },
  "submit": {
    "production": {
      "ios": { "appleId": "team@apple.com", "ascAppId": "123456789" },
      "android": { "serviceAccountKeyPath": "./google-service-account.json" }
    }
  }
}

Push Notifications

import * as Notifications from 'expo-notifications'

async function registerForPushNotifications() {
  const { status } = await Notifications.requestPermissionsAsync()
  if (status !== 'granted') return
  const token = await Notifications.getExpoPushTokenAsync()
  return token.data
}

Notifications.setNotificationHandler({
  handleNotification: async () => ({ shouldShowAlert: true, shouldPlaySound: true }),
})

OTA Updates

Push updates without going through the App Store:

import * as Updates from 'expo-updates'

async function checkForUpdates() {
  const update = await Updates.checkForUpdateAsync()
  if (update.isAvailable) {
    await Updates.fetchUpdateAsync()
    await Updates.reloadAsync()
  }
}
