Node.js util方法的firebase代码组织

我的index.js如下所示

import * as functions from 'firebase-functions';
import * as rp from "request-promise-native";
import * as btoa from "btoa";
import * as admin from 'firebase-admin';
import * as SendGrid from '@sendgrid/mail';
admin.initializeApp(functions.config().firebase)

export const dialog_handler = functions.https.onRequest(async (request, response) => {
    console.log("in dialog_handler request payload is:" + request.body.payload)
    const reqParams = JSON.parse(request.body.payload)

    const callbackId = reqParams.callback_id
    console.log(":::::::::::::::Callback Id:" + callbackId)
    const submission = reqParams.submission
    console.log(submission )
    let payload = {}

    if(callbackId === 'send_feedback'){
        await admin.database().ref("feedback").push(submission);
        payload = { "attachments": [
            {
                "fallback": "Feedback submitted",
                "title": "Feedback submitted. We will get back to you as soon as possible."
            }]
       }

    }
}

上述实际代码并不重要。主要的事情是下面的负载，这对我来说是一种可重用的代码。如何将其移出index.ts，并仅引用它并保持index.tx较小

 payload = { "attachments": [
                {
                    "fallback": "Feedback submitted",
                    "title": "Feedback submitted. We will get back to you as soon as possible."
                }]
           }

这实际上与云函数没有任何关系，而是与TypeScript模块语法和解析有关

您可以有一个相邻的文件

payload.ts

，如下所示：

export const payload = { "attachments": [{
                "fallback": "Feedback submitted",
                "title": "Feedback submitted. We will get back to you as soon as possible."
            }]
       }

然后，您可以从另一个文件获取其值：

import { payload } from "./payload"
