mongodb==安装prisma连接

官网下载mongodb,解压安装

Download MongoDB Community Server | MongoDB

修改bin/mongod.cfg

# mongod.conf# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/# Where and how to store data.
storage:dbPath: D:\sf_develop\mongodb\data# where to write logging data.

创建文件夹D:\sf_develop\mongodb\data\db

下载mongosh

MongoDB Shell Download | MongoDB

启动mongdb

mongod --dbpath D:\sf_develop\mongodb\data\db --replSet rs0

启动mongosh连接上刚才的db

执行rs.initiate

可以了。

安装node.js

创建一个node项目

安装依赖

npm install @prisma/client mongodb
npm install --save-dev prisma
npx prisma init

会发现生成了一个配置文件

编写配置文件

demo-prisma\prisma\schema.prisma

// prisma/schema.prisma
generator client {provider = "prisma-client-js"
}datasource db {provider = "mongodb"url      = env("DATABASE_URL")
}model User {id        String   @id @default(auto()) @map("_id") @db.ObjectIdname      Stringemail     String   @uniqueage       Int?createdAt DateTime @default(now())
}

编写.env文件

DATABASE_URL="mongodb://localhost:27017/prisma-demo"

npx prisma init
会自动在依赖包里生成客户端代码

编写测试代码

const {PrismaClient} = require('@prisma/client');
const prisma = new PrismaClient();async function main() {// CREATE: 新增用户const newUser = await prisma.user.create({data: {name: "Alice",email: "alice@example.com",age: 25,},});console.log("Created user:", newUser);// READ: 查询用户const allUsers = await prisma.user.findMany();console.log("All users:", allUsers);// UPDATE: 更新用户const updatedUser = await prisma.user.update({where: {email: "alice@example.com"},data: {age: 26},});console.log("Updated user:", updatedUser);// // DELETE: 删除用户// const deletedUser = await prisma.user.delete({//     where: {email: "alice@example.com"},// });console.log("Deleted user:", deletedUser);
}main().catch((e) => {console.error(e);process.exit(1);}).finally(async () => {await prisma.$disconnect();});
