If you're new to coding and want to build real websites or web apps, Next.js is one of the best places to start. It's what this site is built on. Here's a straight breakdown of what it is and how it works — no jargon.
What Is Next.js?
Next.js is a framework built on top of React. React is a JavaScript library for building interfaces — buttons, pages, menus, all the visual stuff. Next.js takes React and adds a bunch of things you'd otherwise have to set up yourself: routing, image optimization, backend API routes, and easy deployment.
Think of React as the engine and Next.js as the car already built around it.
The official docs are at nextjs.org/docs — well written and beginner friendly.
How the File Structure Works
This is the biggest thing to understand. In Next.js, your file structure IS your navigation. You don't have to manually configure routes.
If you create a file at `app/about/page.tsx`, you automatically get a `/about` page on your site. Create `app/blog/page.tsx` and you have `/blog`. It just works.
This is called the App Router — it's the modern way Next.js handles navigation.
Pages vs. Components
Two things you'll build constantly:
- • Pages — full screens users navigate to. `/home`, `/about`, `/contact`. Each one lives in its own folder inside `app/`.
- • Components — reusable pieces of UI. A navigation bar, a card, a button. You build them once and use them anywhere.
Server vs. Client Components
This sounds complicated but it's a simple idea once you see it.
- • Server components run on the server before the page loads. Good for fetching data, keeping secrets (like API keys), and anything that doesn't need user interaction. This is the default in Next.js.
- • Client components run in the browser. Required for anything interactive — buttons that do things, forms, state that changes. You mark these with `"use client"` at the top of the file.
Most of what you build will be server components. You only switch to client when something needs to react to what the user does.
Styling
Next.js supports multiple styling approaches out of the box. The most common:
- • CSS Modules — scoped CSS files tied to a specific component
- • Tailwind CSS — utility classes you write directly in your HTML. Most popular choice right now and what I use.
- • Global CSS — one stylesheet that applies everywhere
Deployment
Next.js is made by the same team as Vercel, so deploying there is seamless. You connect your GitHub repo, Vercel detects Next.js automatically, and every push to your main branch triggers a new deployment. Takes about 30 seconds.
You can also deploy on any platform that supports Node.js — but Vercel is the easiest starting point.
Why Learn Next.js Instead of Something Else?
A few reasons:
- • You get frontend and backend in one project — API routes let you handle server logic without spinning up a separate backend
- • File-based routing removes a whole category of setup headaches
- • It's widely used in production — jobs, freelance work, and startups all use it
- • The community is massive, which means answers to your questions are easy to find
If you know basic JavaScript and want to build something real, Next.js is a solid first framework. Start with the official docs — the getting started section walks you through your first project step by step.
