NestJS Firebase C

Question

我正在将 Nestjs 与 firebase admin 集成，控制器没有更新视图。服务没问题，实时更新

有人会提点建议，我的代码有什么问题吗？

注入控制器的服务是：

import { Injectable } from '@nestjs/common';
import * as admin from 'firebase-admin';


export interface Customer {
 direction: string,
 codLegal: string,
 phone: string,
 name: string
}

export interface CustomerId extends Customer{
  id: string;
}


@Injectable()
export class CustomerService {

constructor() {}

findCustomers(): Promise<any>{
    return new Promise((resolve, reject) => {
        admin.firestore().collection('/data/LYvBew5FDpjLqcQjA2Ra/info')
        .onSnapshot((querySnapshot) => {
        const promises: any = [];
        querySnapshot.forEach((doc: any) => {
            promises.push({
                id: doc.id,
                data: doc.data() as Customer,
            });
        });
        console.log(promises);
        resolve(promises);          
        })
    });
 }

}

**基本控制器是：**

import { Controller, Get } from '@nestjs/common';

import { CustomerService } from './services/customer.service';

@Controller('customers') export class CustomerController {

constructor(private readonly customerService: CustomerService) {

}

@Get()
async findAll() {
    try {
        return await this.customerService.findCustomers();
    }catch(err) {
        console.log(err);
    }
}

}

就 HTTP 而言，控制器不会更新视图。一旦您调用 findAll 路由并发送给客户端，就会呈现视图。

如果您想实时显示视图的更新，您应该将 firebase 添加到您的前端。
