Make HTTP Request to Fetch the Data From Web APIs in React Native

This post will give you an idea about how to Make HTTP Request to Fetch the Data From Web APIs in React Native. Here is an interesting example of posting and fetching the data from the server. Whenever you connect your application from the backend server (to get or post the data) you have to make an HTTP  request. Here we will show you how to perform network task in React Native.

Basic Network Call

In the example below, we are using free demo APIs. The example has two button each has its own onPress which triggers our services. Just for the demo purpose, we are using buttons to trigger the request but If You need any data which needs to render while loading your screen you can use componentDidMount lifecycle method to load the data from the server as soon as the component is mounted. So let’s get started.

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run
npm install -g react-native-cli
Run the following commands to create a new React Native project
react-native init ProjectName
This will make a project structure with an index file named App.js in your project directory.

Open App.js in any code editor and replace the code with the following code.

App.js

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
