前端之家收集整理的这篇文章主要介绍了
如何使用离子2 /角度2和打字稿设置firebase,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
从离子1过渡到离子2并且很好奇如何从’somewhere / foo /’设置firebase import *作为Firebase的东西;使用他们的打字稿示例.
> bower是在离子中安装js依赖项的标准方法
2或者我应该使用其他一些构建链/工具来添加
像Firebase这样的东西?
>我应该使用bower install来安装firebase库还是
应该直接指向firebase cdn脚本源?
>我应该使用typings来安装firebase打字稿定义吗?
这是firebase教程https://www.firebase.com/docs/web/libraries/ionic/guide.html中的旧代码
的index.html
<!-- AngularFire -->
<script src="https://cdn.firebase.com/libs/angularfire/1.2.0/angularfire.min.js"></script>
app.js
angular.module("starter",["ionic","firebase"])
其中只包含对Firebase库的cdn引用.我们如何在离子2和打字稿中做到这一点

ionic2应用程序中没有bootstrap …

>在应用程序组件上设置提供程序

您可以侦听这样的身份验证事件
ngOnInit() {
// subscribe to the auth object to check for the login status
// of the user,if logged in,save some user information and
// execute the firebase query...
// .. otherwise
// show the login modal page
this.auth.subscribe((data) => {
console.log("in auth subscribe",data)
if (data) {
this.authInfo = data.password
this.bookItems = this.af.list('/bookItems');
} else {
this.authInfo = null
this.displayLoginModal()
}
})
}
