FirebaseUI React Components

FirebaseUI React Components provides React Wrappers on top of the Firebase UI Web library and notably Firebase UI Auth.

FirebaseUI Auth provides a drop-in auth solution that handles the UI flows for signing in users with email addresses and passwords, and Identity Provider Sign In using Google, Facebook and others. It is built on top of Firebase Auth.

Installation and Usage

For an example on how to use the FirebaseAuth react component have a look at the example folder.

Install the npm package in your React app:

npm install --save react-firebaseui

You also need the firebase package installed which is a peer dependency:

npm install --save firebase

In your app:

1. Import the FirebaseAuth component from react-firebaseui and import firebase.
2. Configure Firebase as described in the Firebase Docs.
3. Write a Firebase UI configuration as described in firebase/firebaseui-web.
4. Use the FirebaseAuth component in your template passing it the Firebase UI configuration and a Firebase Auth instance.

Using FirebaseAuth with a redirect

Below is an example on how to use FirebaseAuth with a redirect upon sign-in:

// Import FirebaseAuth and firebase.
import React from 'react';
import { FirebaseAuth } from 'react-firebaseui';
import firebase from 'firebase';

// Configure Firebase.
const config = {
  apiKey: 'AIzaSyAeue-AsYu76MMQlTOM-KlbYBlusW9c1FM',
  authDomain: 'myproject-1234.firebaseapp.com',
  // ...
};
firebase.initializeApp(config);

// Configure FirebaseUI.
const uiConfig = {
  // Popup signin flow rather than redirect flow.
  signInFlow: 'popup',
  // Redirect to /signedIn after sign in is successful. Alternatively you can provide a callbacks.signInSuccess function.
  signInSuccessUrl: '/signedIn',
  // We will display Google and Facebook as auth providers.
  signInOptions: [
    firebase.auth.GoogleAuthProvider.PROVIDER_ID,
    firebase.auth.FacebookAuthProvider.PROVIDER_ID
  ]
};

class SignInScreen extends React.Component {
  render() {
    return (
      <div>
        <h1>My App</h1>
        <p>Please sign-in:</p>
        <FirebaseAuth uiConfig={uiConfig} firebaseAuth={firebase.auth()}/>
      </div>
    );
  }
}

Using FirebaseAuth with local state.

Below is an example on how to use FirebaseAuth with a state change upon sign-in:

// Import FirebaseAuth and firebase.
import React from 'react';
import { FirebaseAuth } from 'react-firebaseui';
import firebase from 'firebase';

// Configure Firebase.
const config = {
  apiKey: 'AIzaSyAeue-AsYu76MMQlTOM-KlbYBlusW9c1FM',
  authDomain: 'myproject-1234.firebaseapp.com',
  // ...
};
firebase.initializeApp(config);

class SignInScreen extends React.Component {
  
  state = {
    signedIn: false // Local signed-in state.
  };
  
  // Configure FirebaseUI.
  uiConfig = {
    // Popup signin flow rather than redirect flow.
    signInFlow: 'popup',
    // We will display Google and Facebook as auth providers.
    signInOptions: [
      firebase.auth.GoogleAuthProvider.PROVIDER_ID,
      firebase.auth.FacebookAuthProvider.PROVIDER_ID
    ],
    // Sets the `signedIn` state property to `true` once signed in.
    callbacks: {
      signInSuccess: () => {
        this.setState({signedIn: true});
        return false; // Avoid redirects after sign-in.
      }
    }
  };
  
  render() {
    if (!this.state.signedIn) {
      return (
        <div>
          <h1>My App</h1>
          <p>Please sign-in:</p>
          <FirebaseAuth uiConfig={this.uiConfig} firebaseAuth={firebase.auth()}/>
        </div>
      );
    }
    return (
      <div>
        <h1>My App</h1>
        <p>Welcome! You are now signed-in!</p>
      </div>
    );
  }
}

Packing your app

The FirebaseAuth component needs a global CSS to get proper styling. The CSS is already imported within FirebaseAuth. If you are using webpack you'll need to add CSS loaders:

{
  module: {
    rules: [
      {
        test: /\.css/,
        use: [ 'style-loader', 'css-loader' ]
      }
    ]
  }
}

With ExtractTextPlugin

If you are using ExtractTextPlugin to extract a CSS file from the required CSS files you would typically use:

{
  plugins: [new ExtractTextPlugin('./bundle.css')],
  module: {
    rules: [
      {
        test: /\.css/,
        loader: ExtractTextPlugin.extract(
          {
            fallback: 'style-loader',
            use: ['css-loader']
          })
      }
    ]
  }
}

With ExtractTextPlugin and CSS modules

If you are using CSS modules in your app you need to handle the CSS files in /node_modules/ in a separate loader so that they are imported as global CSS files and not modules. Your setup could look like:

{
  plugins: [new ExtractTextPlugin('./bundle.css')],
  module: {
    rules: [
      // CSS loaders for CSS modules in your project. We exclude CSS files in ./node_modules
      {
        test: /\.css$/,
        exclude: [/\.global\./, /node_modules/],
        loader: ExtractTextPlugin.extract(
          {
            fallback: 'style-loader',
            use:[
              {
                loader: 'css-loader',
                options: {
                  importLoaders: 1,
                  modules: true,
                  autoprefixer: true,
                  minimize: true,
                  localIdentName: '[name]__[local]___[hash:base64:5]'
                }
              }
            ]
          })
      },

      // CSS loaders for global CSS files which includes files in ./node_modules
      {
        test: /\.css/,
        include: [/\.global\./, /node_modules/],
        loader: ExtractTextPlugin.extract(
          {
            fallback: 'style-loader',
            use: ['css-loader']
          })
      }
    ]
  }
}

Styling

To change the styling of the FirebaseAuth widget you can override its CSS. You can import a CSS that will be included globally in your packed application. For instance create a firebaseui-overrides.global.css file and import it in your app:

import './firebaseui-overrides.global.css'; // Import globally.

Note: If you are using the "With ExtractTextPlugin and CSS modules" Webpack build rule above, the .global.css suffixe will make sure the CSS file is imported globally and not ran through modules support.

If you would like to see an example of styling, have a look at the example app.

Using multiple instances

In the case where you would need to load multiple instances of FirebaseAuth at the same time you need to set them up with a different ID using the elementId attribute. For instance:

<FirebaseAuth elementId="auth_1" uiConfig={this.uiConfig} firebaseAuth={firebase.auth()}/>
<FirebaseAuth elementId="auth_2" uiConfig={this.otherUiConfig} firebaseAuth={firebase.auth()}/>
