Mastering API Calls in React Native: A Comprehensive Guide with Fetch and Axios

Introduction

As the demand for feature-rich and dynamic mobile applications continues to rise, integrating APIs into your React Native projects becomes crucial. APIs (Application Programming Interfaces) enable communication between different software applications, allowing you to fetch data from remote servers, authenticate users, and perform various backend operations. In this guide, we’ll explore two popular methods for making API calls in React Native: Fetch and Axios.

Section 1: The Fundamentals of API Calls

Before we dive into Fetch and Axios, let’s understand the fundamentals of making API calls in React Native. API calls involve sending HTTP requests to remote servers and handling the responses received. These responses usually contain data in formats like JSON or XML. In our examples, we’ll be working with JSON data.

Section 2: Making a GET API Call

Using Fetch:

Fetch is a built-in web API available in modern browsers and React Native. It allows you to make various types of network requests, including GET. Here’s how to make a GET request using Fetch:

fetch(‘https://api.example.com/data')
