nest.js学习笔记(四)

1、typeorm在nest.js中的使用

环境依赖安装

npm install --save @nestjs/typeorm typeorm mysql2

在app.module.ts进行数据连接配置

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { snakeNameStrategy } from './shared/typeorm-snake-name-strategy';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'mysql',
      host: '127.0.0.1',
      port: 3306,
      username: 'root',
      password: '',
      database: 'even',
      namingStrategy: snakeNameStrategy, // 定义表名与字段的命令策略
      entities: [__dirname + '/**/*.entity{.ts,.js}'], // 定义表的数据模型
      synchronize: false, // 是否关闭同步，通常建议关闭
    }),
    CourseModule,
  ]
})
export class AppModule {}

定义数据模型

import { Entity, Column, PrimaryColumn } from 'typeorm';

@Entity()
export class Tag {
    @PrimaryColumn('char', { length: 36, nullable: false, comment: 'tag id' })
    public id: string;

    @Column('varchar', { length: 100, comment: 'tag title', unique: true })
    public tagName: string;

    @Column('int', { comment: 'create time', unsigned: true, nullable: false })
    public createTime: number;

    @Column('int', { comment: 'update time', unsigned: true, nullable: false })
    public updateTime: number;
}
