## Status

![Status: Archived](https://img.shields.io/badge/Status-Archived-red)

This library is no longer actively maintained. We **do not recommend** using this library in production.

If you maintain a fork of this library that you believe is healthier than the official version, we may consider recommending your fork. Please open a Pull Request if you believe that is the case.

## <firebase-app>

The firebase-app element is used for initializing and configuring your
connection to firebase.

## <firebase-auth>

`firebase-auth` is a wrapper around the Firebase authentication API. It notifies
successful authentication, provides user information, and handles different
types of authentication including anonymous, email / password, and several OAuth
workflows.

Example Usage:

```html

```

The `firebase-app` element initializes `app` in `firebase-auth` (see
`firebase-app` documentation for more information), but an app name can simply
be specified at `firebase-auth`'s `app-name` property instead.

JavaScript sign-in calls can then be made to the `firebase-auth` object to
attempt authentication, e.g.:

```javascript
this.$.auth.signInWithPopup()
.then(function(response) {// successful authentication response here})
.catch(function(error) {// unsuccessful authentication response here});
```

This popup sign-in will then attempt to sign in using Google as an OAuth
provider since there was no provider argument specified and since `"google"` was
defined as the default provider.

## <firebase-document>

The firebase-document element is an easy way to interact with a firebase
location as an object and expose it to the Polymer databinding system.

For example:

```html

```

This fetches the `noteData` object from the firebase location at
`/users/${userId}/notes/${noteId}` and exposes it to the Polymer
databinding system. Changes to `noteData` will likewise be, sent back up
and stored.

`` needs some information about how to talk to Firebase.
Set this configuration by adding a `` element anywhere in your
app.

## <firebase-query>

`firebase-query` combines the given properties into query options that generate
a query, a request for a filtered, ordered, immutable set of Firebase data. The
results of this Firebase query are then synchronized into the `data` parameter.

Example usage:

```html

Polymer({
properties: {
uid: String,
data: {
type: Object,
observer: 'dataChanged'
}
},

dataChanged: function (newData, oldData) {
// do something when the query returns values
}
});

```
