Question

我正在使用Firebase服务器端代码来发送推送通知。为了使代码干净，我决定将一些函数移动到我创建的另一个类，并调用notificationFunctions.js。

当我在const notificationFunctions = require('notificationFunctions');顶部index.js并在我的sendNotification函数中调用该函数时，在将项目部署到云时出现错误：

Functions deploy had errors. To continue deploying other features (such as database), run:
    firebase deploy --except functions

我还在"notificationFunctions": "1.0.0"中添加了package.json，并将自定义功能移至node_modules文件夹。

向Firebase NodeJS添加自定义类的正确方法是什么？

修改

当我按照Doug Stevenson的建议并从我的package.json删除自定义类，并将该类移动到与index.js相同的目录时，我仍然会收到错误：< / p>

i  deploying functions
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing functions directory for uploading...

Error: Error parsing triggers: Cannot find module 'notificationFunctions'

Try running "npm install" in your functions directory before deploying.

修改2

确定。我想我必须改变将类导入require('./notificationFunctions')的方式，这样就可以在部署项目时删除所有错误。

然而，当我在云上运行代码时，我收到此错误：FIREBASE WARNING: Exception was thrown by user callback. TypeError: notificationFunctions.getNotificationPayload is not a function

我从代码中调用函数的方式是：const payload = notificationFunctions.getNotificationPayload(userLanguage, senderName, groupName, messageContent, messageType);

如果在函数文件夹中向项目添加代码，则无需对package.json依赖项进行任何更改。只有发布到NPM registry的模块才需要npm依赖项。

你的构建正在做什么是在NPM上寻找一个名为“notificationFunctions”的节点模块，那里显然不存在。您应该直接将模块代码与require()和{{1}}下的所有其他代码一起放在那里。

另外，请记住，node_modules未随代码一起部署。 Cloud Functions将获取服务器端的所有npm依赖项，并使它们可用于您的代码。
