Next.js 13 introduces exciting new features that revolutionize web development. In this tutorial, we’ll leverage Next.js 13 to build a basic CRUD (Create, Read, Update, Delete) application for note-taking. By the end of this guide, you’ll have a comprehensive understanding of Next.js 13’s capabilities and how to utilize them effectively.

Setting Up the Environment

Let’s start by creating a new Next.js 13 app with TypeScript support:

npx create-next-app@latest my-nextjs-app --ts

Next, we’ll integrate PocketBase as our backend database solution. Download the PocketBase executable and run it with the following command:

pocketbase serve

Navigating Route Structures

Next.js 13 adopts a new route structure, moving from the traditional Pages directory to the app directory. Create route structures within the app directory to define the URL structure of your app.

// pages/notes/[id].tsx
import { useRouter } from 'next/router';

const NotePage = () => {
  const router = useRouter();
  const { id } = router.query;

  // Fetch note data based on the ID

  return (
    <div>
      {/* Display note details */}
    </div>
  );
};

export default NotePage;

Building the User Interface

Construct the foundational elements of your UI using reserved file names and components provided by Next.js.

// pages/index.tsx
const HomePage = () => {
  return (
    <div>
      <h1>Welcome to My Note App</h1>
      {/* Add navigation links */}
    </div>
  );
};

export default HomePage;

Data Fetching and Rendering

Next.js 13 simplifies data fetching with server components and asynchronous functions. Fetch data from the backend using the Fetch API or PocketBase SDK.

// pages/notes.tsx
const NotesPage = ({ notes }) => {
  // Render list of notes
};

export default NotesPage;

export async function getServerSideProps() {
  // Fetch notes data from the backend
  return {
    props: {
      notes: [], // Populate with fetched data
    },
  };
}

Dynamic Routing and State Management

Implement dynamic routing to create personalized routes based on user interactions. Manage state efficiently using React hooks like useState and useEffect.

// pages/notes/create.tsx
const CreateNotePage = () => {
  // Define state for note creation form

  // Handle form submission

  return (
    <div>
      {/* Create note form */}
    </div>
  );
};

export default CreateNotePage;

Handling Loading and Error States

Gracefully handle loading and error states within your application using Next.js 13’s built-in features.

// pages/notes/[id]/loading.tsx
const LoadingNotePage = () => {
  return <div>Loading...</div>;
};

export default LoadingNotePage;

Interactivity and Data Mutation

Enable client-side interactivity and data mutation for seamless user experiences.

// pages/notes/[id]/edit.tsx
const EditNotePage = () => {
  // Fetch note data based on ID

  // Define state for editing form

  // Handle form submission

  return (
    <div>
      {/* Edit note form */}
    </div>
  );
};

export default EditNotePage;
