Getting Started with React Native and Expo

React Native is a popular framework for building cross-platform mobile applications. Expo, on the other hand, is a set of tools and services that simplifies the React Native development workflow. In this article, we’ll guide you through the process of creating a new React Native app using Expo.


Before you start, ensure that you have Node.js and npm installed on your machine. You can download them from Node.js official website.

Step 1: Install Expo CLI

Open your terminal and run the following command to install Expo CLI globally:

bashCopy code

npm install -g expo-cli

This will install the Expo CLI, allowing you to create and manage Expo projects.

Step 2: Create a New Expo Project

To create a new Expo project, run the following commands:

bashCopy code

# Replace "AppName" with the desired name for your app expo init AppName

During the initialization process, you’ll be prompted to choose a template. For a basic React Native project, select the “blank” template.

Step 3: Navigate to the Project Directory

Navigate into the newly created project directory:

bashCopy code

cd AppName

Step 4: Start the Development Server

Once inside the project directory, start the Expo development server:

bashCopy code

expo start

This will open the Expo Developer Tools in your default web browser. From here, you can run the app on an emulator/simulator or scan the QR code with the Expo Go app on your iOS or Android device.

Customizing Your App

Open the project in your preferred code editor and navigate to the App.js or App.jsx file. This file contains the main component of your app. Customize it according to your requirements.


Congratulations! You’ve successfully created a new React Native app using Expo. You can now build and customize your app, taking advantage of the powerful tools provided by Expo.

Happy coding!
