MySQL

@lucia-auth/adapter-mysql package provides adapters for MySQL drivers:

• mysql2
• PlanetScale serverless

npm install @lucia-auth/adapter-mysql

Schema

You can change the varchar length as necessary. session(id) should be able to hold at least 40 chars.

User ID can be numeric (see Define user ID type) but session ID must be a string type.

CREATE TABLE user (
    id VARCHAR(255) PRIMARY KEY
)

CREATE TABLE user_session (
    id VARCHAR(255) PRIMARY KEY,
    expires_at DATETIME NOT NULL,
    user_id VARCHAR(255) NOT NULL REFERENCES user(id)
)

Drivers

mysql2

Mysql2Adapter takes a Pool or Connection instance from mysql2/promises and a list of table names.

import { Lucia } from "lucia";
import { Mysql2Adapter } from "@lucia-auth/adapter-mysql";
import mysql from "mysql2/promise";

const pool = mysql.createPool();

const adapter = new Mysql2Adapter(pool, {
	user: "user",
	session: "user_session"
});

PlanetScale serverless

PlanetScaleAdapter takes a Client or Connection instance and a list of table names.

import { Lucia } from "lucia";
import { PlanetScaleAdapter } from "@lucia-auth/adapter-mysql";
import { Client } from "@planetscale/database";

const client = new Client();

const adapter = new PlanetScaleAdapter(client, {
	user: "user",
	session: "user_session"
});
