App Router + Server Actions: I code the front AND the back in the same project. Why did I wait so long 😅

Post, like, repost: this is exactly the interface you build in the course, from the feed all the way to going live.

You need to enable JavaScript to run this app.

Same code, same content. The only difference is Next.js. And for Google, that difference changes everything.

One framework, every project

Next.js became the go-to for web development because it adapts to anything. Once you master it, you can build almost anything.

Next.js is everywhere

One framework, every web project you can imagine.

Social networks

Real-time feeds, like the Threads clone you build in this course.

E-commerce

Fast, well-ranked online stores built to sell.

SaaS & dashboards

Complete web apps, with member areas and dashboards.

Blogs & content sites

Sites that climb to the top of Google thanks to server rendering.

Showcase sites

Ultra-fast professional sites for companies, freelancers and portfolios.

Platforms & marketplaces

Multi-user platforms with built-in payments and back-office.

AI applications

Streaming chat and AI interfaces, like ChatGPT.

APIs & back-end

Your own APIs and Server Actions, with no separate server to maintain.

Used in production by OpenAI, TikTok, Notion, Twitch, Netflix, Vercel and thousands more.

What Next.js changes for your site

React alone is an app that runs in the browser. Next.js is a real full-stack site, fast and visible on Google. Here's the difference, concretely.

Without Next.js
  • Your content is built in the browser: Google only indexes an empty page and you stay invisible.
  • You configure routing, the build and the bundler by hand, for hours.
  • Front on one side, back on the other: two projects and two servers to manage.
  • Slow first paint, heavy images, performance score in the red.
With Next.js
  • Your pages are server-rendered: Google sees all your content and ranks you.
  • File-based routing, build and optimization are already there: you code, the rest follows.
  • Front-end and back-end in a single project, with API Routes and Server Actions.
  • Instant server rendering, automatically optimized images, performance in the green.
Bottom line

You go from a React app nobody can find to a fast, well-ranked full-stack site ready to welcome thousands of visitors.

FAQs

What is NextJS?

NextJS is a framework that enables the rapid creation of websites using React as its foundation. It helps developers build fast-loading and easily optimized pages by combining the benefits of client-side and server-side development.
Additionally, it simplifies SEO, which is a major advantage for websites aiming to achieve high visibility on search engines.

How long will it take to complete this course?

Our learners take an average of 50 hours to complete this course.

Are there specific times I need to follow the course?

No, you can follow the course at your own pace as it is entirely online. This means you can take this course whenever and wherever you like.

What level is required to take this course?

This course is suitable for all levels. If you've never used NextJS 16 before, just start from the beginning and follow the modules in order.
If you already have some knowledge of NextJS 16, you can jump directly to the modules that interest you.

Can I ask questions if I have a problem?

Yes, you can ask questions anytime. We have a team of mentors available to help you and answer your questions if you encounter any issues.
You can even join our private community to interact with other learners.

Will I receive a certificate at the end of the course?

Yes, the course is up-to-date with the latest version of NextJS 16. We regularly update our courses to ensure they reflect the latest technology.

Why learn NextJS 16 when AI is on the rise?

Because AI writes code faster than you do, but it does not know what you want. It suggests, it gets things wrong, it produces a solution that half works. Without understanding what it wrote, you can neither fix it nor judge whether it was the right call.
That is exactly why we teach you to work WITH it. BeBot guides you through the exercises, and our Claude Code courses show you how to get ten times more out of it than a beginner who copies and pastes without reading.
The people doing well today are neither the ones refusing AI nor the ones handing everything over to it. They are the ones who can read what it writes, spot what is off, and take back control when it gets stuck.
