使用nestjs和typeorm保存对实体的审计

import { CreateDateColumn, UpdateDateColumn, VersionColumn, DeleteDateColumn } from 'typeorm';

export class BaseEntity {
  @CreateDateColumn()
  createdAt: Date;

  @UpdateDateColumn()
  updatedAt: Date;

  @VersionColumn()
  version: number;

  @DeleteDateColumn()
  deletedAt: Date;
}

import { Entity, Column } from 'typeorm';
import { BaseEntity } from './base.entity';

@Entity()
export class User extends BaseEntity {
  @Column()
  name: string;

  // other columns
}

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { User } from './user.entity';

@Injectable()
export class UserService {
  constructor(
    @InjectRepository(User)
    private userRepository: Repository<User>,
  ) {}

  async createUser(name: string): Promise<User> {
    const user = new User();
    user.name = name;
    return this.userRepository.save(user);
  }

  // other methods
}
