MySQL

MySQL 是一种流行的开源关系型数据库管理系统(RDBMS),被广泛用于构建 Web 应用和其他类型的软件。它提供了一种灵活且可扩展的数据库解决方案,能够高效地存储和检索数据。 更多信息请访问:MySQL

【MySQL is a popular open-source relational database management system (RDBMS) that is widely used for building web applications and other types of software. It provides a flexible and scalable database solution that allows for efficient storage and retrieval of data. Read more here: MySQL.】

示例用法

【Example Usage】

确保你已经安装并配置了 MySQL。然后,你可以将它直接连接到 Better Auth。

【Make sure you have MySQL installed and configured. Then, you can connect it straight into Better Auth.】

auth.ts
import { betterAuth } from "better-auth";
import { createPool } from "mysql2/promise";

export const auth = betterAuth({
  database: createPool({
    host: "localhost",
    user: "root",
    password: "password",
    database: "database",
    timezone: "Z", // Important to ensure consistent timezone values
  }),
});

架构生成与迁移

【Schema generation & migration】

Better Auth CLI 允许你根据你的 Better Auth 配置和插件生成或迁移数据库模式。

【The Better Auth CLI allows you to generate or migrate your database schema based on your Better Auth configuration and plugins.】

联接(实验性)

【Joins (Experimental)】

当 Better-Auth 需要在单个查询中从多张表获取相关数据时,数据库连接(joins)非常有用。像 /get-session/get-full-organization 等端点以及许多其他端点都极大地受益于这一功能,根据数据库延迟的不同,性能提升可达 2 到 3 倍。

【Database joins is useful when Better-Auth needs to fetch related data from multiple tables in a single query. Endpoints like /get-session, /get-full-organization and many others benefit greatly from this feature, seeing upwards of 2x to 3x performance improvements depending on database latency.】

1.4.0 版本起,Kysely 的 MySQL 方言开箱即支持连接操作。

【The Kysely MySQL dialect supports joins out of the box since version 1.4.0.】

要启用此功能,你需要在认证配置中将 experimental.joins 选项设置为 true

【To enable this feature, you need to set the experimental.joins option to true in your auth configuration.】

auth.ts
export const auth = betterAuth({
  experimental: { joins: true }
});

It's possible that you may need to run migrations after enabling this feature.

附加信息

【Additional Information】

MySQL 在底层通过 Kysely 适配器得到支持,任何 Kysely 支持的数据库也将被支持。(在此阅读更多)
