javascript - 无法在 Node 中运行新的 firebase

Question

我正在关注 this talk from google .但是我无法实例化 firebase 对象。

我有一个 package.json 文件并开始于:

npm install firebase --save

然后做了以下事情:

let Firebase = require('firebase');
let myFire   = new Firebase('[link to my app]');

但是，当我从终端运行 johhny-five 应用程序时，出现错误:Firebase 不是函数。

我应该如何实例化对象？ Firebase 是否更改了他们的 API？

_{注意:我将它注入(inject) repl 并运行 >> typeof Firebase 我知道它实际上是一个“对象”。}

Answer 1

是的，他们更改了 API，看一下:Upgrade your Web / Node.js app from Firebase.com .

这就是你现在的做法:

// See https://firebase.google.com/docs/web/setup#project_setup for how to
// auto-generate this config
var config = {
  apiKey: "apiKey",
  authDomain: "projectId.firebaseapp.com",
  databaseURL: "https://databaseName.firebaseio.com"
};

firebase.initializeApp(config);

var rootRef = firebase.database().ref();

要获取 config 值，请转至前面代码顶部的 URL，Add Firebase to your Web Project ，它会指导您执行以下操作:

To add Firebase to your app, you'll need a Firebase project and a short snippet of code to add to your application HTML that has a few details about your project.

1. Create a Firebase project in the Firebase console, if you don't already have one.
   • If you already have an existing Google project associated with your app, click Import Google Project. Otherwise, click Create New Project.
   • If you already have a project, click Add App from the project overview page.
2. Click Add Firebase to your web app.
3. Click Copy, then paste the code snippet into your application HTML.
