我正在尝试开发一个带有nestjs和angular的项目。我的项目文件夹像这样，
项目文件夹
|--服务器（Nestjs应用程序）

• —-|客户端（Angular 应用程序）
• —-|---正面
  我可以在localhost上运行这个应用程序。但是我正在尝试部署到heroku上。我构建了angular应用程序，并将这些文件复制到名为front的文件夹中。然后我将这个文件夹拖到服务器文件夹中。
  在nestjs应用程序的app.module.ts文件中：

@Module({
 imports: [UserModule,

TaskModule,
  MongooseModule.forRoot(secret.mongoUrl),
  LoginModule,
  SignUpModule,
  ServeStaticModule.forRoot({
    rootPath: join(__dirname, '..', 'front')
  })
  ],
  controllers: [AppController],
  providers: [AppService],
})

现在，当我已经启动我的nestjsapp与npm启动我的Angular 和nestjs应用程序完美地在localhost上工作：3000.
这是我的heroku构建日志，
