详解如何使用Node.js连接数据库ORM

class User {
    name: string
    age: string
}

import { Entity, PrimaryGeneratedColumn, Column } from "typeorm";
@Entity()
export class User {
  @Column()
  name: string;
  @Column()
  age: string;
}

const user = new User();  
user.name = "jym";  
user.age = 18;  
await repository.save(user);  
const allUsers = await repository.find();  
const u = await repository.findOne({ name: "jym" });  
await repository.remove(u);

const { Sequelize, DataTypes } = require('sequelize');  
const sequelize = new Sequelize('jym', 'root', 'password', {  
    host: 'localhost',  
    dialect: 'mysql'
});
const User = sequelize.define('User', {  
    // 在这里定义模型属性  
    name: {  
        type: DataTypes.STRING,  
    },  
    age: {  
        type: DataTypes.STRING  
    }  
});

const u = await User.create({ name: "jym" });  
console.log(u.name); // "jym"  
await u.save();
// 查询所有用户  
const users = await User.findAll();
...
const u = await User.findOne({ where: { name: 'jym' } });  
u.name = 'test'
u.save()
u.destroy()

model User {
    id Int @id @default(autoincrement())
    email String @unique
    name String?
    posts Post[]
}

import { PrismaClient } from '@prisma/client'
const prisma = new PrismaClient()
const user = await prisma.user.findUnique({
    where: {
        name: 'jym',
    },
})
