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.ObjectId
  name      String
  email     String   @unique
  age       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();
    });
