React-Native-CLI: 2026 Guide

Introduction

As a mobile application developer, you may have heard about React Native if you are interested in mobile app development. But one of the pervasive phrases that novices have not understood is react-native-cli. In this tutorial, we will explore what is react-native-cli, how it works, and why developers love to use React Native CLI for developing scalable mobile applications.

What is React Native CLI?

React Native CLI is the official Command Line Interface for creating and managing React Native projects without using third-party tools like Expo.

In simple terms:

Using react-native-cli you have full control over your mobile app native code (Android & iOS).

On the other hand, React Native CLI runs like an equal with native modules, which is the most appropriate path for complicated apps (unlike Expo, which abstracts native configurations).

Why Use React Native CLI?

There are some good reasons for developers to opt usage of react-native-cli:

Full access to native code (Java/Kotlin for Android, Swift/Objective-C for iOS)
Better performance for large-scale apps
Support for custom native modules integration
Not using a third-party runtime dependency (like Expo Go)

React Native CLI vs Expo

Having a better understanding of the difference allows you to use the right one at the right time.

Feature	React Native CLI	Expo
Native Code Access	Full	Limited
Ease of Setup	Moderate	Very Easy
Custom Native APIs	Supported	Limited
App Size	Smaller	Larger
Flexibility	High	Medium

For production-level apps, react-native-cli is how it should go in general.

Before You Start

Before we dive into how to install React Native CLI, here are the requirements:

Required Tools

Node.js (latest LTS version)
npm or yarn
Android Studio (for Android development)
Xcode (for macOS users)

Step 1: Install React Native CLI

Follow these steps to install react-native-cli globally:

npm install -g react-native-cli

To verify installation:

react-native --version

Create A Project Using React Native CLI

Creating a project is straightforward:

npx react-native init MyApp

Navigate into your project:

cd MyApp

Running Your React Native App

For Android

npx react-native run-android

For iOS (Mac only)

npx react-native run-ios

Make sure you have the emulator or device configured properly.

Project Structure Explained

When you create a project via react-native-cli, this is what you get:

MyApp/
+-- android/ # Android native code
+-- ios/ // native code for iOS
+-- node_modules/ # Dependencies
+-- App.js # Main application
+-- package.json

Key Folders

android/ – Contains Java/Kotlin code
ios/ – Contains Swift/Objective-C code
App.js – Entry point of your app

When to Use React Native CLI?

Use react-native-cli when:

Advanced native capability support (Bluetooth, sensors, etc.)
You need custom native modules in your application
You’re building enterprise-level applications
Performance optimization is critical

Avoid it if:

You want to quickly prototype applications
You do not want to manage native configurations

Example: Simple React Native Component

import React from 'react';

const App = () => {
  return (
    <h1>Hello from React Native CLI!</h1>
  );
};

export default App;

Advantages of React Native CLI

Greater flexibility and control
Easier integration with third-party libraries
Production-ready setup
Better debugging capabilities

Disadvantages of React Native CLI

Complex setup compared to Expo
Requires knowledge of native development
Longer development time initially
