初始化

npx prisma init

npx prisma init

修改配置文件

/prisma/shcema.prisma

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
}

添加.env环境变量

DATABASE_URL="mysql://backend_user:BackendUser@localhost:3306/backend_db"

DATABASE_URL="mysql://backend_user:BackendUser@localhost:3306/backend_db"

添加测试模型

/prisma/shcema.prisma 添加如下模型信息

model Test {
  id Int @id @default(autoincrement())
  name String @db.VarChar(255)
  desc String?
  number Int
  isPublished Boolean
}

model Test {
  id Int @id @default(autoincrement())
  name String @db.VarChar(255)
  desc String?
  number Int
  isPublished Boolean
}

将模型推送到mysql

npx prisma db push

npx prisma db push

prisma studio

npx prisma studio

npx prisma studio

安装prisma客户端

npm install @prisma/client

npm install @prisma/client

使用prisma客户端

/src/lib/client.ts

import { PrismaClient } from '@prisma/client'

const globalForPrisma = globalThis as unknown as { prisma: PrismaClient }

export const prisma = globalForPrisma.prisma || new PrismaClient()

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma

import { PrismaClient } from '@prisma/client'

const globalForPrisma = globalThis as unknown as { prisma: PrismaClient }

export const prisma = globalForPrisma.prisma || new PrismaClient()

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma
