Question

yarn add nestjs-config

app.module.ts

import * as path from 'path';
import { Module } from '@nestjs/common';

//数据库
import { TypeOrmModule } from '@nestjs/typeorm';

//全局配置
import { ConfigModule, ConfigService } from 'nestjs-config';


@Module({
  imports: [
    //1.配置 config 目录
    ConfigModule.load(path.resolve(__dirname, 'config', '**/!(*.d).{ts,js}')),  
    
    //2.读取配置，这里读取的是数据库配置
TypeOrmModule.forRootAsync({
      useFactory: (config: ConfigService) => config.get('database'), 
      inject: [ConfigService],  // 获取服务注入
    })
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

配置数据库

src -> config -> database

import { join } from 'path';
export default {
  type: 'mysql',
  host: 'localhost',
  port: 3306,
  username: 'root',
  password: 'your password',
  database: 'test',
  entities: [join(__dirname, '../', '**/**.entity{.ts,.js}')],
  synchronize: true,
};
