Data fetching with React Native

React Native offers a streamlined way for developers to build mobile apps, and this guide provides a comprehensive overview of various data-fetching techniques to enhance app functionality. It covers multiple methods, including using the inbuilt Fetch API for loading data on component mount, on button click, or at regular intervals, as well as utilizing Axios and Apisauce for more robust data handling options that support GET, POST, PUT, and DELETE requests. The article also explores the benefits of using GraphQL with the Apollo Client for more efficient data retrieval by querying only necessary fields, thus optimizing data usage. Additionally, it discusses using class components for data fetching, which, while less common in modern React, can be useful for maintaining legacy code. Through practical code examples and a sample app using the Coffee API and NativeBase UI library, developers can choose the most suitable approach for their specific app requirements.
