Solved: create react native app with expo

Creating a React Native app with Expo provides an efficient, complete solution for mobile app development, bypassing much of the usual setup and configuration process. With Expo, developers can access an extensive set of tools and services to expedite the development process.

Expo is essentially a framework and a platform that streamlines React Native applications. It is bundled with a variety of libraries and tools for app development, from testing and iteration to deployment and publication. This makes it a one-stop-shop for mobile app development.

React Native is a Javascript framework that lets you build mobile apps using only JavaScript. Meanwhile, Expo is a set of tools built around React Native, helping you to build and publish React Native applications with minimal fuss.

Now, let’s dive a bit deeper into the process.

Creating a React Native Application with Expo

Let’s walk through the steps involved in creating a new React Native project with Expo.

// First, install Node.js and npm on your machine
// Then install expo with the command:
npm install -g expo-cli
// Now, you can create a new application by typing:
expo init AwesomeProject
// Change to your project's directory
cd AwesomeProject
// And start your app with:
expo start

This will start your app in development mode, opening up a new browser window – the Expo Developer Tools. You can then open your app in the Expo app on your phone and start working on it.

Writing Your First Component

A sample component can be written in Typescript as follows:

import * as React from 'react';
import { Text, View } from 'react-native';

export default function App() {
  return (
      <Text>Welcome to Expo!</Text>

Expo Libraries and Tools

Expo provides a wide array of inbuilt libraries and tools that ease the development process, including but not limited to:

  • Expo SDK: A set of libraries that provide access to device and system functionality for apps including audio, video, geolocation, and much more.
  • Expo Tools: Tools including the Expo CLI, which is a command line app that’s the main interface between developers and Expo services.
  • Expo Snack: An online editor that allows developers to run Expo projects in the browser.

Try exploring and using these features when creating your app, they are built specifically to make your development experience smoother and more efficient!
