When building REST APIs, Prisma Client can be used inside your route controllers to send databases queries.

REST APIs with Prisma Client

Supported libraries

As Prisma Client is "only" responsible for sending queries to your database, it can be combined with any HTTP server library or web framework of your choice.

Here's a non-exhaustive list of libraries and frameworks you can use with Prisma:

REST API server example

Assume you have a Prisma schema that looks similar to this:

datasource db {
provider = "sqlite"
url = "file:./dev.db"
generator client {
provider = "prisma-client-js"
model Post {
id Int @id @default(autoincrement())
title String
content String?
published Boolean @default(false)
author User? @relation(fields: [authorId], references: [id])
authorId Int?
model User {
id Int @id @default(autoincrement())
email String @unique
name String?
posts Post[]

You can now implement route controller (e.g. using Express) that use the generated Prisma Client API to perform a database operation when an incoming HTTP request arrives. This page only shows few sample code snippets, if you want to run these code snippets, you can use the REST API example.


app.get('/feed', async (req, res) => {
const posts = await prisma.post.findMany({
where: { published: true },
include: { author: true },

Note that the feed endpoint in this case returns a nested JSON response of Post objects that include an author object. Here's a sample response:

"id": "21",
"title": "Hello World",
"content": "null",
"published": "true",
"authorId": 42,
"author": {
"id": "42",
"name": "Alice",
"email": "alice@prisma.io"


app.post(`/post`, async (req, res) => {
const { title, content, authorEmail } = req.body
const result = await prisma.post.create({
data: {
published: false,
author: { connect: { email: authorEmail } },


app.put('/publish/:id', async (req, res) => {
const { id } = req.params
const post = await prisma.post.update({
where: { id: Number(id) },
data: { published: true },


app.delete(`/post/:id`, async (req, res) => {
const { id } = req.params
const post = await prisma.post.delete({
where: {
id: Number(id),
