Getting Started with Prisma: A Quick Guide - 9/6/2023

Introduction to Prisma

Prisma is a powerful database toolkit that simplifies database access in Node.js applications. It offers a type-safe and auto-generated query builder that makes working with databases a breeze. In this guide, we’ll walk through the basics of setting up and using Prisma.

Installation

To get started with Prisma, you’ll need Node.js and npm installed on your system. You can install Prisma globally using the following command:

pnpm install -g prisma

Initializing a Prisma Project

Once Prisma is installed, you can initialize a new Prisma project in your Node.js application directory

prisma init

This will create a new Prisma project in your current directory. You can then configure your database connection in the prisma/schema.prisma file.

Define Your Data Model

Next, you’ll need to define your data model in the prisma/schema.prisma file. This is where you’ll define your database tables and their relationships. For example, if you want to create a User table with an id, name, and email field, you can do so as follows:

model User {
  id    Int     @id @default(autoincrement())
  name  String
  email String  @unique
}

model Post {
  id       Int       @id @default(autoincrement())
  title    String
  content  String
  author   User      @relation(fields: [authorId], references: [id])
  authorId Int
}

Migrate Your Database

Once you’ve defined your data model, you can migrate your database using the following command:

prisma generate
prisma migrate dev

This will create the necessary tables in your database and generate the Prisma client for your Node.js application.

Using the Prisma Client

Now that you’ve generated the Prisma client, you can use it in your Node.js application to access your database. For example, if you want to create a new user, you can do so as follows:

// Seed the database with a new user
const newUser = await prisma.user.create({
  data: {
    name: "John Doe",
    email: "jhonedoe@email.com",
  },
});

console.log(user);
// { id: 1, name: 'John Doe', email: 'johnedoe@gmailcom' }
