NestJS 将 ConfigService 与 TypeOrmModule 结合使用

Question

我按照文档中的描述设置了 ConfigService https://docs.nestjs.com/techniques/configuration

如何将此服务与 TypeOrmModule 一起使用？

TypeOrmModule.forRoot({
  type: 'mysql',
  host: 'localhost',
  port: 3306,
  username: 'root',
  password: 'root',
  database: 'test',
  entities: [__dirname + '/**/*.entity{.ts,.js}'],
  synchronize: true,
}),

Answer 1

参见https://docs.nestjs.com/techniques/database异步配置章节

import {ConfigService} from './config.service';
import {Module} from '@nestjs/common';
import {TypeOrmModule} from '@nestjs/typeorm';

@Module({
    imports: [
        TypeOrmModule.forRootAsync({
            imports: [ConfigModule],
            useFactory: (config: ConfigService) => config.get('database'),
            inject: [ConfigService],
        }),
    ],
})
export class AppModule {}

Answer 2

如果您想使用配置 class ConfigService, use useClass and provide TypeOrmConfigService

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { ConfigModule } from './config/config/config.module';
import { TypeOrmConfigService } from './config/typeorm.config';
import { ConfigService } from './config/config/config.service';

@Module({
  imports: [
    ConfigModule,
    TypeOrmModule.forRootAsync({
      imports: [ConfigModule],
      useClass: TypeOrmConfigService,
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}
