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;

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);
}

以上的答案为我指明了正确的方向，只是没有一个真正适合我。下面是一个工作原型，一个onCall, onRequest和数据库触发器的例子

foo.js - 随叫随到，随叫随到。

exports.handler = async function(data, context, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

bar.js - onRequest

exports.handler = async function(req, res, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

jar.js - trigger/document/onCreate .js

exports.handler = async function(snapshot, context, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

index.js

//导入firebase管理SDK依赖项

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase); 

// import functions
const foo = require("./foo");
const bar = require("./bar");
const jar = require("./jar");

// onCall for foo.js
exports.foo = functions.https.onCall((data, context) => {
    return foo.handler(data, context, admin);
});

// onRequest for bar.js
exports.bar = functions.https.onRequest((req, res) => {
    return bar.handler(req, res, admin);
});

// document trigger for jar.js
exports.jar = functions.firestore
  .document("parentCollection/{parentCollectionId}")
  .onCreate((snapshot, context) => {
    return jar.handler(snapshot, context, admin);
});

注意:你也可以创建一个子文件夹来存放你的各个函数

这种格式允许您的入口点查找其他函数文件，并自动导出每个文件中的每个函数。

主要入口脚本

找到functions文件夹中的所有.js文件，并导出从每个文件中导出的每个函数。

const fs = require('fs'); const path = require('path'); // Folder where all your individual Cloud Functions files are located. const FUNCTIONS_FOLDER = './scFunctions'; fs.readdirSync(path.resolve(__dirname, FUNCTIONS_FOLDER)).forEach(file => { // list files in the folder. if(file.endsWith('.js')) { const fileBaseName = file.slice(0, -3); // Remove the '.js' extension const thisFunction = require(`${FUNCTIONS_FOLDER}/${fileBaseName}`); for(var i in thisFunction) { exports[i] = thisFunction[i]; } } });

从一个文件导出多个函数

Const functions = require('firebase-functions'); Const query = functions.https。onRequest((req, res) => { Let query = req.query.q; res.send ({ “You searching For”:查询 })； })； const searchTest = functions.https。onRequest((req, res) => { res.send ({ "searchTest": "你好!" })； })； 模块。出口= { 查询 searchTest ｝

HTTP可访问端点有适当的命名

✔功能:查询:http://localhost:5001/PROJECT-NAME/us-central1/query function: helloWorlds: http://localhost:5001/PROJECT-NAME/us-central1/helloWorlds ✔功能:searchTest: http://localhost:5001/PROJECT-NAME/us-central1/searchTest

一个文件

如果你只有几个额外的文件(例如只有一个)，你可以使用:

Const your_functions = require('./path_to_your_functions'); For (var I in your_functions) { export [i] = your_functions[i]; ｝
