Introduction

Prisma is an open-source data access layer that simplifies database management in modern applications. It offers a strong API to communicate with databases and supports various databases like PostgreSQL, MySQL, MongoDB, etc. Integrating Prisma with a Next.js app can boost database management and app performance, as well as increase reliability and security with its type safety and data protection features.

This blog post provides a step-by-step guide on integrating Prisma into a Next.js app. The post covers the entire process, from setting up a Next.js project to testing the integration, and is aimed at developers who want to improve their database management skills. Even new Next.js or Prisma users should be able to follow the guide and integrate Prisma successfully. By the end of the guide, developers will have a complete understanding of integrating Prisma into their Next.js app.

Setting up a Next.js project

Creating a new Next.js project is the first step in integrating Prisma into a Next.js app. This process involves setting up a basic Next.js app that serves as the foundation for the rest of the integration process. Here are the steps to create a new Next.js project:

1. Install Node.js and npm (Node Package Manager) if you don't already have them installed on your system.

2. Open a terminal or command prompt and navigate to the directory where you want to create your Next.js project.

3. Run the following command to create a new Next.js project using npm:

   npx create-next-app my-app
   

4. Select the options that you would like for your project:

   ✔ Would you like to use TypeScript with this project? No
   ✔ Would you like to use ESLint with this project? Yes
   

5. This command will create a new Next.js project in a directory named my-app. Change the directory to the newly created project by running:

   cd my-app
   

6. To start the development server, run the following command:

   npm run dev
   

7. Open a web browser and navigate to http://localhost:3000 to see the default Next.js "Hello World" page.

Installing and setting up Prisma

Installing and setting up Prisma is the next step after creating a new Next.js project. This process involves installing the necessary dependencies, setting up a Prisma client, and connecting it to a database. Here are the steps to install and set up Prisma:

1. Install the Prisma client and the required dependencies by running the following command:

   npm install @prisma/client
   

2. Initialize a new Prisma service by running the following command:

   npx prisma init
   

3. In the prisma directory, update the file called schema.prisma and add the following code:

   prisma/schema.prisma

   datasource db {
     provider = "sqlite"
     url = "file:./dev.db"
   }
   
   generator client {
     provider = "prisma-client-js"
   }
   
   model User {
     id    String  @id @default(uuid())
     name  String
     email String  @unique
   }
   

4. After the Prisma service is set up, you need to generate the Prisma client by running the following command:

   npx prisma generate
   

5. In your Next.js project, create a new file called db.js in the lib directory and add the following code:

   lib/db.js

   import { PrismaClient } from "@prisma/client";
   
   const prisma = new PrismaClient();
   
   export default prisma;
   

6. Push the changes to the database by running the following command:

   npx prisma db push
   

Adding seed data to the table

Adding seed data to the table is a useful step in developing a Next.js app with Prisma. Seed data provides initial data for your database, which can be used for testing and development purposes. Here are the steps to add seed data to the table:

1. In the prisma directory, create a new file called seed.js and add the following code:

   prisma/seed.js

   const db = require("../lib/db");
   
   const users = [
     { name: "John Doe", email: "john.doe@example.com" },
     { name: "Jane Doe", email: "jane.doe@example.com" }
   ];
   
   async function seed() {
     for (const user of users) {
       await db.user.create({ data: user });
     }
   }
   
   seed().catch(console.error);
   

2. This code requires the db client and defines an array of users with two objects. It then creates an asynchronous function seed that loops through the users array and creates a new user in the User table for each object in the array using the db.user.create method.

3. To run the seed data script, run the following command in your terminal:

   node prisma/seed.js
   

Connecting Prisma to Next.js

Connecting Prisma to Next.js is the final step in integrating Prisma into a Next.js app. This step involves using the Prisma client to connect to the database and make queries and mutations. Here are the steps to connect Prisma to Next.js:

1. In the pages/api directory, create a new file called users.js and add the following code:

   pages/api/users.js

   import db from "../../lib/db";
   
   export default async function handler(req, res) {
     const users = await db.user.findMany();
     res.status(200).json(users);
   }
   

2. This code imports the db client and defines an asynchronous function handler that uses the db.user.findMany method to retrieve all users from the User table. It then returns the users array as a JSON response.

3. Open a web browser and navigate to http://localhost:3000/api/users to see the JSON response.

4. In your Next.js project, create a new file called users.js in the pages directory and add the following code:

   pages/users.js

   import { useState, useEffect } from "react";
   
   export default function Users() {
     const [users, setUsers] = useState([]);
   
     useEffect(() => {
       fetch("/api/users")
         .then((res) => res.json())
         .then((data) => setUsers(data));
     }, []);
   
     return (
       <div>
         <h1>Users</h1>
         <ul>
           {users.map((user) => (
             <li key={user.id}>{user.name}</li>
           ))}
         </ul>
       </div>
     );
   }
   

5. This code imports the useState and useEffect hooks from React and defines a Users component that uses the useState hook to initialize an empty array of users. It then uses the useEffect hook to fetch the users from the /api/users endpoint and set the users state with the response data.

6. If you navigate to http://localhost:3000/users, you should see the list of users from the database.

Using Prisma Studio to debug the database

Using Prisma Studio to debug the database is a useful step in developing a Next.js app with Prisma. Prisma Studio is a GUI tool that allows you to view and edit data in your database. Here are the steps to use Prisma Studio to debug the database:

1. In your terminal, run the following command to start Prisma Studio:

   npx prisma studio
   

2. Open a web browser and navigate to http://localhost:5555 to see the Prisma Studio interface.

3. In the Prisma Studio interface, click on the User table to see the list of users.

4. Click on the Add record button to add a new user to the database.

5. In the Add new User form, enter the following values:

   • name: John Smith
   • Email: john@smith.com

6. Click on the Save button to save the new user to the database.
