【中文标题】NestJS 和 Mongoose 使用 Mongoose-Sequence【英文标题】：NestJS and Mongoose Using Mongoose-Sequence 【发布时间】：2020-11-11 04:01:51 【问题描述】：我正在尝试在我的 NestJS 应用程序中使用插件“mongoose-sequence”。我希望这个插件可以被我将为这个应用程序创建的所有模块使用。这是我的 app.module.ts：
import Module from '@nestjs/common';
import MongooseModule from '@nestjs/mongoose';
import UsersModule from './user/user.module';
import AutoIncrementFactory from 'mongoose-sequence';
const mongoUri = 'mongodb://localhost/apptest';
const connName = 'apptest';
@Module(
imports: [
MongooseModule.forRoot(mongoUri,
connectionName: connName,
useFindAndModify: false,
connectionFactory: (connection, connName) =>
const AutoIncrement = AutoIncrementFactory(connection);
connection.plugin(AutoIncrement);
return connection;
),
UserModule,
],
controllers: [],
providers: [],
);
export class AppModule
当我启动服务器时，我收到以下错误消息：

任何想法，为什么插件无法连接到 mongodb？ mongodb 正在运行，我通过 mongo 客户端连接到它，当我删除 const AutoIncrement... 和 connection.plugin(... 行时。
更新：
将 AutoIncrementFactory 的导入更改为：
import AutoIncrementFactory = require('mongoose-sequence');
产生超过最大呼叫统计大小：
更新 2：在下面进行了建议的更改，同样的错误。

【问题讨论】：
【参考方案1】：mongoose-sequence 不是 ES6 模块。
在第一个版本中，您使用导入，而在第二个版本中，您将 import 和 require 混合使用，这是不允许的。
你应该试试
const AutoIncrementFactory = require('mongoose-sequence');
【讨论】：
进行了建议的更改，我得到了与以前一样的最大调用堆栈大小超出错误。 我有同样的问题，我也尝试了这里提供的解决方案***.com/questions/62824276/… 但是当我生成一个新模型时，orderId 没有填充。以上是关于NestJS 和 Mongoose 使用 Mongoose-Sequence的主要内容，如果未能解决你的问题，请参考以下文章
