Prisma adapter

Adapter for Prisma provided by the Prisma adapter package. There are 2 ways to initialize it.

import { prisma } from "@lucia-auth/adapter-prisma";
const prisma: (
	client: PrismaClient,
	modelNames?: {
		user: string;
		key: string;
		session: string | null;
) => InitializeAdapter<Adapter>;
clientPrismaClientThe Prisma client
modelNames.sessionstring | nullCan be null when using alongside a session adapter

The values for the modelNames params is the camelCase version of your PascalCase model names defined in your schema (sounds confusing but the TS auto-complete should help you). When it’s undefined, the adapter uses predefined model names (see below).


npm i @lucia-auth/adapter-prisma
pnpm add @lucia-auth/adapter-prisma
yarn add @lucia-auth/adapter-prisma


import { lucia } from "lucia";
import { prisma } from "@lucia-auth/adapter-prisma";
import { PrismaClient } from "@prisma/client";

const client = new PrismaClient();

const auth = lucia({
	adapter: prisma(client)
	// ...

// default values
const auth = lucia({
	adapter: prisma(client, {
		user: "user", // model User {}
		key: "key", // model Key {}
		session: "session" // model Session {}
	// ...

In non-Node.js environment#

To use Prisma in an environment that doesn’t support Node.js (including Deno, Cloudflare Workers, Vercel Edge), import PrismaClient from @prisma/client/edge instead of @prisma/client.

import { PrismaClient } from "@prisma/client/edge";

Prisma schema#

You can add additional columns to the user model to store user attributes, and to the session model to store session attributes. If you change the model names, pass the new names to the adapter config.

The id fields are not UUID types with the default configuration.

model User {
  id           String    @id @unique

  auth_session Session[]
  key          Key[]

model Session {
  id             String @id @unique
  user_id        String
  active_expires BigInt
  idle_expires   BigInt
  user           User   @relation(references: [id], fields: [user_id], onDelete: Cascade)


model Key {
  id              String  @id @unique
  hashed_password String?
  user_id         String
  user            User    @relation(references: [id], fields: [user_id], onDelete: Cascade)
