React and APIs - Full Tutorial - Hacker News API Application

Dive into an intermediate-level tutorial on integrating APIs with React by building a Hacker News API application. Learn to implement React memo, make API calls using Axios, style components, and conduct tests with React Testing Library. Explore the creation of a small React application that efficiently handles 500+ automated API calls, utilizing memo to prevent redundant network requests. Gain insights into using the Lighthouse browser extension for assessing accessibility and performance. Cover essential topics including scaffolding with create-react-app, refactoring exports, environment file modification, and API integration. Master component creation, state management with useEffect, styled components implementation, and infinite scrolling functionality. Delve into testing practices, including Jest coverage and fixture usage. Conclude by optimizing the application with React memo and evaluating its performance through Lighthouse.
