What is React Native?

React Native is a popular open-source JavaScript framework used to develop mobile applications for both Android and iOS operating systems. Developed by Facebook, React Native enables developers to create native mobile applications using JavaScript and the React library.


React Native is based on the same design principles as React, which is a JavaScript library for building user interfaces. It is used to create a rich user interface using components, props, and states. React Native also utilizes the same core architecture as React, making it easy to learn and use.


React Native is a great choice for developers who want to create native mobile applications without having to learn a new language. It is also a great choice for developers who want to create applications that are cross-platform compatible, as it can be used to create applications for both Android and iOS. Additionally, it is easy to learn and use, making it an ideal choice for developers of all experience levels.


How to start development on React Native

Here are the steps to start developing the best React Native app:


  1. Install dependencies:

To begin developing a React Native app, the first step is to install the necessary dependencies. This can be done by using the command line interface to install the React Native CLI and the necessary packages. It is important to use a forceful polite tone when communicating with the command line interface, as this will help ensure that the installation process is successful. Once the dependencies have been installed, the next step is to create a React Native project and begin developing the app. An example is Node.js, React Native CLI, Xcode for iOS development, and Android Studio for Android development.

Steps to install dependencies in React Native:


  • Step 1: Navigate to your project's root directory in the terminal/command prompt.

  • Step 2: Run ‘npm install’ or ‘yarn add’ followed by the name of the dependency you want to install.

  • Step 3: For example, to install react-navigation, run ‘npm install react-navigation’ or ‘yarn add react-navigation’.

  • Step 4: Repeat step 2 for each dependency you want to install.

  • Step 5: Run ‘npm install’ or ‘yarn’ to install all dependencies listed in your project's package.json file.

  • Step 6: To confirm installation, run ‘npm ls’ or ‘yarn list’ to see the list of installed dependencies.

  • Step 7: Import the installed dependency into your React Native component and start using it.


  1. Start a fresh project utilizing the React Native Command Line Interface (CLI).

Let's get started with React Native! First, we'll create a new project using the React Native Command Line Interface. This is the first step in creating a great React Native app, and it's sure to be an exciting journey. Let's get started and see what amazing things we can create.

Steps to create a new project:


  • Step 1: Install React Native CLI globally: ‘npm install -g react-native-cli’

  • Step 2: Create a new project: ‘react-native init projectName’

  • Step 3: Change to the project directory: ‘cd projectName’

  • Step 4: Run the app on Android: ‘react-native run-android’ or on iOS: ‘react-native run-ios’


  1. Navigate to the project directory: 

Navigating the project directory in React Native is a critical step in the development process. It is essential that developers understand how to access the project directory in order to begin working on the project. To navigate to the project directory in React Native, open the command line interface and use the "cd" command to change the directory to the project folder. Once the command is executed, developers will be able to access the project directory and begin working on the project. It is important to remember that navigating to the project directory is the first step in the development process, so it is essential that developers understand how to do this correctly.

Steps to create:


  • Step 1: Activate the command prompt or terminal

  • Step 2: Use the ‘cd’ command to navigate to the desired directory.

For example ‘cd ~/projects/myDirectory’ (to navigate to a directory named "myDirectory" inside a directory called "projects" in your home directory).


  1. Start the development server: 

Starting the development server in React Native is an essential step in the development process. It is a command-line interface tool that enables developers to launch the app in the simulator or device. It also provides a local server to serve the JavaScript code and assets and enables developers to debug the app. This server must be started before running the app and can be done by using the command "react-native start" in the project directory. Failing to start the development server will result in an inability to run the app, so it is imperative that developers remember to start the server before running any React Native application.

Steps to start the development server:


  • Step 1: defineNavigate to the project folder in your terminal or command prompt.

  • Step 2:Run the following command: ‘npx react-native start’

  • Step 3:Once the development server is started, you can run the app on an emulator or device by using the command: ‘npx react-native run-android’ (for Android) or ‘npx react-native run-ios’ (for iOS).

  • Step 4:To view the app in a development environment, open the emulator or connect your device and run the command from step 3.


*Note: Ensure that you have all the necessary dependencies installed, such as Node.js, Java Development Kit (for Android), Xcode (for iOS), and the React Native CLI.
