Easy, type-safe database Access
in Fastify servers

Query data from MySQL, PostgreSQL & SQL Server databases in Fastify apps with Prisma – a better ORM for JavaScript and TypeScript.

See code examples

What is Prisma?

Prisma makes working with data easy! It offers a type-safe Node.js & TypeScript ORM, global database caching, connection pooling, and real-time database events.

Get started with Prisma

Query

// Creating a new record
await prisma.user.create({
  firstName: “Alice”,
  email: “alice@prisma.io”
})

Table

id  firstName    email  
1   Bobby        bobby@tables.io
2   Nilufar      nilu@email.com
3   Jürgen       jums@dums.edu
4   Alice        alice@prisma.io

How Prisma and Fastify fit together

Prisma ORM is a next-generation ORM that's used to query your database in a Fastify server. You can use it as an alternative to writing plain SQL queries, query builders like knex.js or traditional ORMs like TypeORM, MikroORM and Sequelize. Prisma ORM can be used to build REST and GraphQL APIs and integrates smoothly with both microservices and monolithic architectures.

You can also supercharge usage of Prisma ORM with our additional tools:
• Prisma Accelerate is a global database cache and scalable connection pool that speeds up your database queries.
• Prisma Pulse enables you to build reactive, real-time applications in a type-safe manner.

Prisma and Fastify code examples

Prisma provides a convenient database access layer that integrates perfectly with Fastify.

The code below demonstrates various uses of Prisma when using Fastify for building an API server.

REST API

Prisma is used inside your route handlers to read and write data in your database.

1import fastify from 'fastify'
2import { PrismaClient } from '@prisma/client'
3
4const prisma = new PrismaClient()
5const app = fastify()
6
7app.get('/feed', async (req, res) => {
8  const posts = await prisma.post.findMany({
9    where: { published: true },
10    include: { author: true },
11  })
12  res.json(posts)
13})
14
15app.post('/post', async (req, res) => {
16  const { title, content, authorEmail } = req.body
17  const post = await prisma.post.create({
18    data: {
19      title,
20      content,
21      published: false,
22      author: { connect: { email: authorEmail } },
23    },
24  })
25  res.json(post)
26})
27
28app.put('/publish/:id', async (req, res) => {
29  const { id } = req.params
30  const post = await prisma.post.update({
31    where: { id },
32    data: { published: true },
33  })
34  res.json(post)
35})
36
37app.delete('/user/:id', async (req, res) => {
38  const { id } = req.params
39  const user = await prisma.user.delete({
40    where: {
41      id,
42    },
43  })
44  res.json(user)
45})
46
47app.listen(3000)
