我已经在ES2017代码中编写了我的firebase函数，因为我无法使用ES2017 JavaScript部署函数，所以我必须将其编写。我理解它的方式是import UIKit
class ViewController: UIViewController {
@IBOutlet weak var GoButton: UIButton!
@IBOutlet weak var Background: UIImageView!
@IBOutlet weak var SettingsButton: UIButton!
@IBOutlet weak var aboutButton: UIButton!
@IBAction func toFlashcards(_ sender: Any) {
self.Background.image = nil
}

super.viewDidLoad()
}

提供在我的本地环境（使用ES2017）中运行的功能，firebase serve将功能部署到云（没有ES2017）。
在部署之前，我firebase deploy和babel在主文件夹中抓取我的index.js文件，将其转换并放入/ dist文件夹以及一些配置文件。
为了从./dist文件夹中部署firebase，我在package.json中设置了入口点npm run prepare。但是，这意味着当我想要"main": "./dist/index.js"用于本地环境时，我会从./dist文件夹中提供已转换的函数。所以我必须在firebase serve和"main": "index.js"之间不断更改，具体取决于我是想在本地提供函数还是部署转换后的函数。
尽管已经指定了我想要服务和部署的位置，如下所示：
"main": "./dist/index.js"
我的整个package.json文件：
"scripts": {
"lint": "./node_modules/.bin/eslint .",
"serve": "firebase serve --only functions",
"shell": "firebase experimental:functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions/dist",
"logs": "firebase functions:log"
}
