🔧 What is Prisma?

Prisma is a next-generation ORM (Object-Relational Mapping) tool for Node.js and TypeScript. It simplifies database access with auto-generated queries, full TypeScript support, and a beautiful developer experience.

✅ Why Prisma + Next.js?

Type-safe queries ✨

Great DX with auto-completion

Works smoothly with Next.js API routes

🧰 Prerequisites

Before we get started, make sure you have:

Node.js installed

A Next.js project ready (or run npx create-next-app)

A database (PostgreSQL, MySQL, SQLite, etc.)

📦 Step 1: Install Prisma

Then initialize Prisma:

This will create a new folder prisma/ and a .env file.

⚙️ Step 2: Configure Your Database

Open the .env file and set your DATABASE_URL:

If you already have an existing database, Prisma can introspect it! More on that later. 👇

🧱 Step 3: Define Your Data Model

In prisma/schema.prisma, define your data model like this:

Want to generate models from an existing database? Just run:

Prisma will automatically introspect your database and generate the models for you. 🪄

🛠️ Step 4: Migrate & Generate

Create your first migration and generate the Prisma Client:

Or if you used db pull, just run:

📁 Step 5: Set Up Prisma Client in Your App

Create a helper file at lib/prisma.ts:

This prevents multiple instances of PrismaClient during development (a common problem with hot-reloading in Next.js).

🔌 Step 6: Use Prisma in API Routes

Here’s how to use it in an API route like app/api/queryUser/route.ts:

You can now query your database easily with full type safety! 💥

🤗 Final Thoughts

Using Prisma in your Next.js project unlocks powerful database capabilities with type safety, clarity, and speed. Whether you're starting fresh or introspecting an existing DB with prisma db pull, Prisma makes full-stack development a joy. 🔥
