为了保持简单(但能完成工作)，我个人是这样构造我的代码的。

布局

├── /src/                      
│   ├── index.ts               
│   ├── foo.ts           
│   ├── bar.ts
|   ├── db.ts           
└── package.json  

foo.ts

import * as functions from 'firebase-functions';
export const fooFunction = functions.database()......... {
    //do your function.
}

export const someOtherFunction = functions.database().......... {
    // do the thing.
}

bar.ts

import * as functions from 'firebase-functions';
export const barFunction = functions.database()......... {
    //do your function.
}

export const anotherFunction = functions.database().......... {
    // do the thing.
}

db.ts

import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';

export const firestore = admin.firestore();
export const realtimeDb = admin.database();

index.ts

import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';

admin.initializeApp(functions.config().firebase);
// above codes only needed if you use firebase admin

export * from './foo';
export * from './bar';

适用于任何嵌套级别的目录。也只需遵循目录中的模式即可。

这要归功于@zaidfazil的答案

更新:Typescript现在完全支持，所以不需要下面的恶作剧。只需使用firebase cli

以下是我个人是如何使用typescript的:

/functions
   |--src
      |--index.ts
      |--http-functions.ts
      |--main.js
      |--db.ts
   |--package.json
   |--tsconfig.json

在此之前，我先提出两点警告:

进口/出口的顺序在index.ts中很重要 db必须是一个单独的文件

第二点，我不知道为什么。其次，你应该完全尊重我的index, main和db的配置(至少要尝试一下)。

索引。Ts:与出口有关。我觉得让索引更干净。贸易部门负责出口。

// main must be before functions
export * from './main';
export * from "./http-functions";

主要。ts:处理初始化。

import { config } from 'firebase-functions';
import { initializeApp } from 'firebase-admin';

initializeApp(config().firebase);
export * from "firebase-functions";

db。Ts:只是重新导出数据库，所以它的名字比database()短。

import { database } from "firebase-admin";

export const db = database();

http-functions.ts

// db must be imported like this
import { db } from './db';
// you can now import everything from index. 
import { https } from './index';  
// or (both work)
// import { https } from 'firebase-functions';

export let newComment = https.onRequest(createComment);

export async function createComment(req: any, res: any){
    db.ref('comments').push(req.body.comment);
    res.send(req.body.comment);
}

我有这个项目，它有后台函数和http函数。我还有用于单元测试的测试。CI/CD将使您在部署云功能时更加轻松

文件夹结构

|-- package.json
|-- cloudbuild.yaml
|-- functions
    |-- index.js
    |-- background
    |   |-- onCreate
    |       |-- index.js
            |-- create.js
    |
    |-- http
    |   |-- stripe
    |       |-- index.js
    |       |-- payment.js
    |-- utils
        |-- firebaseHelpers.js
    |-- test
        |-- ...
    |-- package.json

注意:utils/文件夹用于在函数之间共享代码

函数/ index.js

在这里，您可以导入所需的所有函数并声明它们。这里不需要逻辑。在我看来，这样更干净。

require('module-alias/register');
const functions = require('firebase-functions');

const onCreate = require('@background/onCreate');
const onDelete = require('@background/onDelete');
const onUpdate = require('@background/onUpdate');

const tours  = require('@http/tours');
const stripe = require('@http/stripe');

const docPath = 'tours/{tourId}';

module.exports.onCreate = functions.firestore.document(docPath).onCreate(onCreate);
module.exports.onDelete = functions.firestore.document(docPath).onDelete(onDelete);
module.exports.onUpdate = functions.firestore.document(docPath).onUpdate(onUpdate);

module.exports.tours  = functions.https.onRequest(tours);
module.exports.stripe = functions.https.onRequest(stripe);

CI / CD

每次将更改推送到回购时都进行持续集成和部署如何?你可以使用谷歌谷歌云构建。它是免费的，直到某个点:)检查这个链接。

。/ cloudbuild.yaml

steps:
  - name: "gcr.io/cloud-builders/npm"
    args: ["run", "install:functions"]
  - name: "gcr.io/cloud-builders/npm"
    args: ["test"]
  - name: "gcr.io/${PROJECT_ID}/firebase"
    args:
      [
        "deploy",
        "--only",
        "functions",
        "-P",
        "${PROJECT_ID}",
        "--token",
        "${_FIREBASE_TOKEN}"
      ]

substitutions:
    _FIREBASE_TOKEN: nothing

org大纲是一个更简单的体系结构模式，可以将方法分离到不同的文件中，并在index.js文件中的一行中导出。

本示例中项目的架构如下:

projectDirectory

index.js podcast.js profile.js

index.js

const admin = require('firebase-admin');
const podcast = require('./podcast');
const profile = require('./profile');
admin.initializeApp();

exports.getPodcast = podcast.getPodcast();
exports.removeProfile = profile.removeProfile();

podcast.js

const functions = require('firebase-functions');

exports.getPodcast = () => functions.https.onCall(async (data, context) => {
      ...
      return { ... }
  });

同样的模式将用于概要文件中的removeProfile方法。

Firebase文档现在已经更新了一个多文件代码组织的好指南:

文档>云功能>写功能>组织功能

总结:

foo.js

const functions = require('firebase-functions');
exports.foo = functions.https.onRequest((request, response) => {
  // ...
});

bar.js

const functions = require('firebase-functions');
exports.bar = functions.https.onRequest((request, response) => {
  // ...
});

index.js

const foo = require('./foo');
const bar = require('./bar');
exports.foo = foo.foo;
exports.bar = bar.bar;
