Free Udemy Course: Full-Stack Development for Beginner: React, Next.js, Node.js

Become a Full-Stack Developer by building real-world projects with React, Next.js, Node.js, and REST APIs. In this course, you’ll learn modern web development step by step — from frontend basics to backend APIs.You will start by mastering React fundamentals (JSX, Virtual DOM, Components, Props, State, Hooks, Events, Effects, Styling).Next, you’ll build apps with Next.js (Pages, Layouts, Routing, Navigation, Dynamic Segments, Server/Client Data Fetching, Suspense, Loading states).Finally, you’ll use Node.js to create REST APIs (HTTP core, Modules, Async/Await) and connect them to your frontend.By the end of this course, you will know how to:Build Frontend Apps with ReactConnect to third-party APIs including AI APIsDevelop Full-Stack projects with Next.jsCreate REST APIs with Node.jsWhat's in this course?REACT BASIC ModuleLearn the Core Skills of React.
