FeathersJS -将useUnifiedTopology添加到MongoDB

Question

我正在通过feathers-mongo使用FeathersJS和MondoDB

我想以某种方式将useUnifiedToplogy:true传递给连接器的设置，但是它似乎没有在生成的服务(feathers generate service)中公开。

这是我的logging.class.ts

import { Db } from 'mongodb';
import { Service, MongoDBServiceOptions } from 'feathers-mongodb';
import { Application } from '../../declarations';
import {Paginated, Params} from "@feathersjs/feathers";

export class Logging extends Service {
  constructor(options: Partial<MongoDBServiceOptions>, app: Application) {
    super(options);

    const client: Promise<Db> = app.get('mongoClient');

    client.then(db => {
      this.Model = db.collection('users');
    });
  }
};

在root有一个mongodb.ts

import { MongoClient } from 'mongodb';
import { Application } from './declarations';

export default function (app: Application) {
  const connection = app.get('mongodb');
  const database = connection.substr(connection.lastIndexOf('/') + 1);
  const mongoClient = MongoClient.connect(connection, { useNewUrlParser: true, useUnifiedTopology: true })
    .then(client => client.db(database));

  app.set('mongoClient', mongoClient);
}
