Next.js Authentication Tutorial

Authentication can be a huge hassle for software engineer, understanding the user, where it come from, what the user intention are can be a world of trouble. also, providing multiple solutions for authentication and user identification verification can be very difficult for beginners, if you want to learn how to do authentication read this article and also try to use gpteach to learn how to write nextjs code.

Understanding Next.js, Frameworks, and Libraries

• What is Next.js?
  Next.js is a popular React framework (a preset structure created to make development easier) that allows for server-side rendering and great performance optimizations. It is widely used for building modern web applications.

• Framework vs. Library
  A framework (complete ready-to-use solution) provides a set of tools and guidelines to build applications, while a library (collection of functions) consists of reusable code snippets that you can use within your project.

Next.js Authentication Tutorial

Next.js authentication tutorial aims to guide you through implementing user authentication in a Next.js application. To get started, we will cover the basics of setting up authentication and securing routes in a Next.js project.

Important to Know

Before diving into the implementation, let's cover some important concepts that you need to be familiar with when working on Next.js authentication.

1. Next.js Routing (determining which component should be rendered based on the URL)

// pages/index.js
import Link from 'next/link';

const Home = () => (
  <>
    <h1>Welcome to Next.js Authentication Tutorial</h1>
    <Link href="/login"><a>Login</a></Link>
  </>
);

export default Home;

2. Next.js API Routes (setting up endpoints to handle authentication logic)

// pages/api/login.js
export default (req, res) => {
  // Handle login logic
  res.status(200).json({ message: 'Login successful' });
};
