Full Definition

Expo is the recommended way to start a React Native project. It handles the complex native build setup, provides a library of pre-built APIs (camera, location, notifications), and lets you test your app instantly with Expo Go (no build needed). Expo Router adds file-based routing to React Native (similar to Next.js). Expo apps can be built in the cloud with EAS Build.
Expo هو الطريقة الموصى بها لبدء مشروع React Native. يتعامل مع إعداد البناء الأصلي المعقد ويوفر مكتبة من APIs الجاهزة (الكاميرا والموقع والإشعارات) ويتيح اختبار تطبيقك فورًا مع Expo Go (لا حاجة للبناء). يضيف Expo Router توجيهًا معتمدًا على الملفات إلى React Native (مماثلًا لـ Next.js). يمكن بناء تطبيقات Expo في السحابة بـ EAS Build.

Example Usage

“npx create-expo-app MyApp يُنشئ مشروع React Native جديدًا مع Expo. امسح رمز QR بـ Expo Go لرؤيته على هاتفك فورًا.”
