🤖 Introduction

Build a full-stack Real Estate application with React Native, featuring Google authentication, dynamic property listings, and user profiles. Designed with modern tools like Expo SDK 52, Appwrite, Tailwind CSS, and TypeScript for a seamless and scalable experience.

⚙️ Tech Stack

Expo is an open-source platform for building universal native apps (Android, iOS, web) using JavaScript/TypeScript and React Native. It features file-based routing via Expo Router, fast refresh, native modules for camera/maps/notifications, over-the-air updates (EAS), and streamlined app deployment.
React Native is a framework for building mobile UIs with React. It enables component‑based, cross-platform development with declarative UI, deep native API support, and is tightly integrated with Expo for navigation and native capabilities.
Appwrite is an open-source backend-as-a-service platform offering secure authentication (email/password, OAuth, SMS, magic links), databases, file storage with compression/encryption, real-time messaging, serverless functions, and static site hosting via Appwrite Sites—all managed through a unified console and microservices architecture.
TypeScript is a statically-typed superset of JavaScript providing type annotations, interfaces, enums, generics, and enhanced tooling. It improves error detection, code quality, and scalability—ideal for robust, maintainable projects.
NativeWind brings Tailwind CSS to React Native and Expo, allowing you to style mobile components using utility-first classes for fast, consistent, and responsive UI design.
Tailwind CSS is a utility-first CSS framework enabling rapid UI design via low-level classes. In React Native/Expo, it’s commonly used with NativeWind to apply Tailwind-style utilities to mobile components.

🔋 Features

👉 Authentication with Google: Secure and seamless user sign-ins using Google’s authentication service.

👉 Home Page: Displays the latest and recommended properties with powerful search and filter functionality.

👉 Explore Page: Allows users to browse all types of properties with a clean and intuitive interface.

👉 Property Details Page: Provides comprehensive information about individual properties, including images and key details.

👉 Profile Page: Customizable user settings and profile management

👉 Centralized Data Fetching: Custom-built solution inspired by TanStack’s useQuery for efficient API calls.

and many more, including code architecture and reusability

Prerequisites

Make sure you have the following installed on your machine:

Git
Node.js
npm (Node Package Manager)

Cloning the Repository

git clone https://github.com/adrianhajdin/react_native-restate.git
cd react_native-restate

Installation

npm install

Set Up Environment Variables

Create a new file named .env.local in the root of your project and add the following content:

EXPO_PUBLIC_APPWRITE_ENDPOINT=https://cloud.appwrite.io/v1
EXPO_PUBLIC_APPWRITE_PROJECT_ID=
EXPO_PUBLIC_APPWRITE_DATABASE_ID=
EXPO_PUBLIC_APPWRITE_GALLERIES_COLLECTION_ID=
EXPO_PUBLIC_APPWRITE_REVIEWS_COLLECTION_ID=
EXPO_PUBLIC_APPWRITE_AGENTS_COLLECTION_ID=
EXPO_PUBLIC_APPWRITE_PROPERTIES_COLLECTION_ID=

Replace the values with your actual Appwrite credentials. You can obtain these credentials by signing up & creating a new project on the Appwrite Dashboard.

Start the app

 npx expo start

In the output, you'll find options to open the app in a

development build
Android emulator
iOS simulator
Expo Go, a limited sandbox for trying out app development with Expo

You can start developing by editing the files inside the app directory. This project uses file-based routing.
