In 2024, React is still the #1 skill to learn if you want to become a successful front-end developer!

But it can be hard. There are so many moving parts, so many different libraries, so many tutorials out there.

That's why you came here... And you came to the right place! This is THE ultimate React course for 2024 and beyond.

A practice-heavy approach to master React by building polished apps, backed up by diagrams, theory, and looks under the hood of React.

The all-in-one package that takes you from zero to truly understanding React and building modern, powerful, and professional web applications.

Real projects. Real explanations. Real React.

[01] Why is this the right React course for you?

This is the most epic React (+ Next.js) course on Udemy, and it's fundamentally different from all the other ones.

Here's why:

• Contains the biggest and most professional project, where we implement many common app features (see promo video!)

• Super detailed explanations of all important concepts with carefully crafted and animated diagrams

• A huge focus on "how to think in React" and modern best practices

• A long section that explores how React actually works behind the scenes will give you the confidence to use React effectively on your own

• Advanced design patterns like compound components will make you think like a senior React engineer

• Many sections (16 hours!) on Next.js with the modern "app" router (with React Server Components and Server Actions)

And these are just the highlights! Check out the full list below (+ the promo video and curriculum).

Also, make no mistake: "React course" actually means "Front-end development with React and modern libraries course".

That's right, besides the React library itself, you will learn and master them all: React Router, Redux, Redux Toolkit, React Query, React Hook Form, Styled Components, Tailwind CSS, Next.js, and more.

This is how we plan, build, and deploy professional projects! We even use industry-standard tools such as Supabase (fully-fledged back-end), GitHub, Netlify, and Vercel.

As you expect, this course is 100% project-based. So throughout the course, you'll start building your portfolio of 10+ beautiful and high-quality React apps, where each one will showcase a few of the new skills you will be learning.

By the end of the course, you will have all the knowledge and confidence that you need to ace your job interviews and become the professional React developer that companies are looking for.

[03] Still not sure? Here are all the nerdy details of what we'll cover:

• React fundamentals [why we even need React, components, JSX, props, events, forms, state, props vs. state]

• How to think about state [where to place state, guidelines, lifting state up, local vs. global state, UI vs. remote state]

• How to think about components [how to split components, props as API, how to build reusable and composable components, the children prop]

• Deep dive into effects and useEffect [data fetching, lifecycle vs. synchronization, when to use effects, effects vs. event handlers]

• Deep dive into hooks [rules of hooks, how hooks work, useRef, building super-reusable custom hooks]

• Advanced state management [useReducer hook, the Context API, Redux, Redux Toolkit, Thunks, React Query]

• Building Single-Page Applications (SPA) [Vite, routing with React Router, URL parameters and query strings for state management, data loaders and actions (v6.4+)]

• Building real-world features found in many apps [authentication and authorization, data sorting, filtering and pagination, dark mode, dashboard with charts, etc.]

• Creating your own back-end with a DB and API using Supabase [gain the power to build full-stack apps on your own!]

• How to style React apps [Tailwind CSS, CSS Modules, and Styled Components]

• Advanced React patterns used by senior developers [render props, higher-order components, compound components (to build a modal, a context menu, and more)]

• How React works behind the scenes [rendering, virtual DOM, reconciliation, fiber tree, key prop, events, state batching, etc.]
