Drizzle ORM for Cloudflare D1

适用于Cloudflare D1的Drizzle ORM

Status: Production Ready ✅ Last Updated: 2025-12-14 Latest Version: drizzle-orm@0.44.7, drizzle-kit@0.31.7 Dependencies: cloudflare-d1, cloudflare-worker-base
状态：已就绪可用于生产 ✅ 最后更新：2025-12-14 最新版本：drizzle-orm@0.44.7，drizzle-kit@0.31.7 依赖项：cloudflare-d1、cloudflare-worker-base

Quick Start (10 Minutes)

快速开始（10分钟）

1. Install Drizzle

1. 安装Drizzle

bash
bun add drizzle-orm drizzle-kit
bash
bun add drizzle-orm drizzle-kit

2. Configure Drizzle Kit

2. 配置Drizzle Kit

Create 
drizzle.config.ts
:
typescript
import { defineConfig } from 'drizzle-kit';

export default defineConfig({
  schema: './src/db/schema.ts',
  out: './migrations',
  dialect: 'sqlite',
  driver: 'd1-http',
  dbCredentials: {
    accountId: process.env.CLOUDFLARE_ACCOUNT_ID!,
    databaseId: process.env.CLOUDFLARE_DATABASE_ID!,
    token: process.env.CLOUDFLARE_D1_TOKEN!,
  },
});
创建 
drizzle.config.ts
：
typescript
import { defineConfig } from 'drizzle-kit';

export default defineConfig({
  schema: './src/db/schema.ts',
  out: './migrations',
  dialect: 'sqlite',
  driver: 'd1-http',
  dbCredentials: {
    accountId: process.env.CLOUDFLARE_ACCOUNT_ID!,
    databaseId: process.env.CLOUDFLARE_DATABASE_ID!,
    token: process.env.CLOUDFLARE_D1_TOKEN!,
  },
});

3. Define Schema

3. 定义Schema

Create 
src/db/schema.ts
:
typescript
import { sqliteTable, text, integer } from 'drizzle-orm/sqlite-core';
import { relations } from 'drizzle-orm';

export const users = sqliteTable('users', {
  id: integer('id').primaryKey({ autoIncrement: true }),
  email: text('email').notNull().unique(),
  name: text('name').notNull(),
  createdAt: integer('created_at', { mode: 'timestamp' }).$defaultFn(() => new Date()),
});

export const posts = sqliteTable('posts', {
  id: integer('id').primaryKey({ autoIncrement: true }),
  title: text('title').notNull(),
  content: text('content').notNull(),
  authorId: integer('author_id')
    .notNull()
    .references(() => users.id, { onDelete: 'cascade' }),
});

export const usersRelations = relations(users, ({ many }) => ({
  posts: many(posts),
}));
创建 
src/db/schema.ts
：
typescript
import { sqliteTable, text, integer } from 'drizzle-orm/sqlite-core';
import { relations } from 'drizzle-orm';

export const users = sqliteTable('users', {
  id: integer('id').primaryKey({ autoIncrement: true }),
  email: text('email').notNull().unique(),
  name: text('name').notNull(),
  createdAt: integer('created_at', { mode: 'timestamp' }).$defaultFn(() => new Date()),
});

export const posts = sqliteTable('posts', {
  id: integer('id').primaryKey({ autoIncrement: true }),
  title: text('title').notNull(),
  content: text('content').notNull(),
  authorId: integer('author_id')
    .notNull()
    .references(() => users.id, { onDelete: 'cascade' }),
});

export const usersRelations = relations(users, ({ many }) => ({
  posts: many(posts),
}));

4. Generate & Apply Migrations

4. 生成并应用迁移

bash
bunx drizzle-kit generate                           # Generate SQL
bunx wrangler d1 migrations apply my-database --local   # Apply local
bunx wrangler d1 migrations apply my-database --remote  # Apply prod
bash
bunx drizzle-kit generate                           # 生成SQL语句
bunx wrangler d1 migrations apply my-database --local   # 本地环境应用
bunx wrangler d1 migrations apply my-database --remote  # 生产环境应用

5. Query in Worker

5. 在Worker中执行查询

typescript
import { drizzle } from 'drizzle-orm/d1';
import { users } from './db/schema';
import { eq } from 'drizzle-orm';

export default {
  async fetch(request: Request, env: { DB: D1Database }): Promise<Response> {
    const db = drizzle(env.DB);
    const allUsers = await db.select().from(users).all();
    return Response.json(allUsers);
  },
};
typescript
import { drizzle } from 'drizzle-orm/d1';
import { users } from './db/schema';
import { eq } from 'drizzle-orm';

export default {
  async fetch(request: Request, env: { DB: D1Database }): Promise<Response> {
    const db = drizzle(env.DB);
    const allUsers = await db.select().from(users).all();
    return Response.json(allUsers);
  },
};

Critical Rules

重要规则

Always Do

务必遵守

RuleWhy
Use 
drizzle-kit generate
for migrations		Never write SQL manually
Test migrations locally first
--local
before 
--remote
Use 
.get()
for single results		Returns first row or undefined
Use 
db.batch()
for transactions		D1 doesn't support SQL BEGIN/COMMIT
Use 
integer
with 
mode: 'timestamp'
for dates		D1 has no native date type
Use 
.$defaultFn()
for dynamic defaults		Not 
.default()
for functions
规则原因
使用
drizzle-kit generate
生成迁移		切勿手动编写SQL
先在本地测试迁移先使用
--local
再执行
--remote
使用
.get()
获取单条结果		返回第一行数据或undefined
使用
db.batch()
执行事务		D1不支持SQL BEGIN/COMMIT语法
日期类型使用带
mode: 'timestamp'
的
integer
D1无原生日期类型
动态默认值使用
.$defaultFn()
函数类型的默认值不能使用
.default()

Never Do

切勿执行

RuleWhy
Use SQL 
BEGIN TRANSACTION
D1 requires batch API (Error #1)
Mix 
drizzle-kit migrate
and 
wrangler apply
Use Wrangler only
Use 
drizzle-kit push
for production		Use 
generate
+ 
apply
Commit credentials in drizzle.config.tsUse env vars
Use 
.default()
for function calls		Use 
.$defaultFn()
instead
规则原因
使用SQL 
BEGIN TRANSACTION
D1要求使用批量API（错误编号#1）
混合使用
drizzle-kit migrate
和
wrangler apply
仅使用Wrangler执行迁移
生产环境使用
drizzle-kit push
应使用
generate
+ 
apply
组合
在drizzle.config.ts中提交凭证信息使用环境变量存储凭证
函数调用使用
.default()
应改用
.$defaultFn()

Top 5 Critical Errors

五大常见关键错误

#ErrorSolution
1
D1_ERROR: Cannot use BEGIN TRANSACTION
Use 
db.batch([...])
instead of 
db.transaction()
2
FOREIGN KEY constraint failed
Define cascading: 
.references(() => users.id, { onDelete: 'cascade' })
3
env.DB is undefined
Ensure binding in 
wrangler.jsonc
matches 
env.DB
4
No such module "wrangler"
Use 
import { drizzle } from 'drizzle-orm/d1'
5
Type instantiation excessively deep
Use 
InferSelectModel<typeof users>
for explicit types
See: 
references/error-catalog.md
for all 12 errors with complete solutions.
序号错误解决方案
1
D1_ERROR: Cannot use BEGIN TRANSACTION
使用
db.batch([...])
替代
db.transaction()
2
FOREIGN KEY constraint failed
定义级联操作：
.references(() => users.id, { onDelete: 'cascade' })
3
env.DB is undefined
确保
wrangler.jsonc
中的绑定与
env.DB
匹配
4
No such module "wrangler"
使用
import { drizzle } from 'drizzle-orm/d1'
5
Type instantiation excessively deep
使用
InferSelectModel<typeof users>
声明显式类型

references/error-catalog.md

TypeScript Type Inference

TypeScript类型推断

typescript
import { InferSelectModel, InferInsertModel } from 'drizzle-orm';
import { users } from './db/schema';

export type User = InferSelectModel<typeof users>;
export type NewUser = InferInsertModel<typeof users>;
typescript
import { InferSelectModel, InferInsertModel } from 'drizzle-orm';
import { users } from './db/schema';

export type User = InferSelectModel<typeof users>;
export type NewUser = InferInsertModel<typeof users>;
