我试图初始化我的angular(typescript)应用程序以使用firebase。我有一个FirebaseService
类,它有一个初始化应用程序的方法,即
import {Injectable} from "@angular/core";
import * as firebase from 'firebase';
const firebaseConfig = {
apiKey: // my api key,
authDomain: // my auth domain,
databaseURL: // my database url,
storageBucket: // my storage bucket,
};
@Injectable()
export class FirebaseService {
start(): void {
console.log("Starting firebase");
firebase.initializeApp(firebaseConfig);
};
}
我在应用程序启动时调用FirebaseService.Start
,但我目前在浏览器控制台中收到以下错误
Starting firebase

我的SystemJS配置设置如下
(function (global) {
System.config({
paths: {
// paths serve as alias
"lib:": 'lib/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
// angular bundles
'@angular/core': 'lib:@angular/core/bundles/core.umd.js',
'@angular/common': 'lib:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'lib:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'lib:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'lib:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'lib:@angular/http/bundles/http.umd.js',
'@angular/router': 'lib:@angular/router/bundles/router.umd.js',
'@angular/forms': 'lib:@angular/forms/bundles/forms.umd.js',
'rxjs': 'lib:rxjs',
'firebase': 'lib:firebase'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
firebase: {
main: 'firebase.js',
defaultExtension: 'js'
}
}
});
})(this);
因此它应该可以从我的firebase.js
文件夹中加载lib
。查看firebase.js
肯定会出现一个名为initializeApp
的函数,即
initializeApp:function(a,c){void 0===c?c="[DEFAULT]":"string"===typeof c&&""!....
所以我无法解决我出错的地方。有什么想法吗?
我使用angular v2.2.0和firebase v3.6.1
答案 0 :(得分:1)
我想知道同样的事情:
我可以直接使用
firebase
而不使用angularfire2
吗?
但无论如何,您可以将angularfire2
库用于Angular
项目。

对于System.js
,this doc中有更多信息。
修改强>
也可以使用不firebase
的{{1}},例如:
angularfire2
