React Native Azure AD B2C solution using Pure JS. If you are using expo you dont need to eject.

Thanks to https://github.com/sonyarouje/react-native-ad-b2c and https://github.com/wkh237/react-native-azure-ad packages for the inspiration.

Feel free to contribute or sponsor. :)

Installation

Don't forget to install peer dependencies "react": "^16.8.3", "react-native-webview": "^7.0.1"

npm i ad-b2c-react-native -S

Usage

The code below is just a sample implementation to just demonstrate the API of the components. As-Is copy paste of below will not work.

Login screen

import React from 'react';
import { Alert } from 'react-native';
import { LoginView } from 'ad-b2c-react-native';
import * as SecureStore from 'expo-secure-store';

export default class Login extends React.PureComponent {
  static navigationOptions = { header: null };

  constructor(props) {
    super(props);
    this.onLogin = this.onLogin.bind(this);
    this.onFail = this.onFail.bind(this);
    this.spinner = this.spinner.bind(this);
  }

  onLogin() {
    const { navigation } = this.props;
    navigation.navigate('App');
  }

  onFail(reason) {
    Alert.alert(reason);
  }

  spinner() {
  //this is just a sample implementation, so copy pasting will not work as the components used below are custom
  //and are not in imports above. Please replace it with your implementation.
  return (
        <CView> //custom wrapper around View
            <Spinner /> //component wrapping loading status symbol(e.g spinner)
        </CView>
    );
  }

  render() {
      //apart from these props you can use any webview props

      //for *secureStore*, you can pass expo's secure store or create your own wrapper,
      //which implements deleteItemAsync(key), getItemAsync(key), setItemAsync(key, data)

      //*scope is optional*,if provided will overwrite the default scope {appId offline_access}
      //*Suggestion*: with custom scope, id and refresh tokens will not be returned,
      //so consider using format 'openid offline_access {your scope} '

    return (
      <LoginView
        appId="myAppId"
        redirectURI="myRedirectURI"
        tenant="myTenant"
        loginPolicy="B2C_1_SignUpSignIn"
        passwordResetPolicy="B2C_1_PasswordReset"
        profileEditPolicy="B2C_1_ProfileEdit"
        onSuccess={this.onLogin}
        onFail={this.onFail}
        secureStore={MySecureStore}
        renderLoading={this.spinner}
        scope="openid offline_access myScope1 myScope2 ...." //optional, but see the notes above
      />
    );
  }
}

Logout screen

import React from 'react';
import { Alert } from 'react-native';
import {LogoutView} from 'ad-b2c-react-native';

export default class Logout extends React.PureComponent {
  static navigationOptions = { header: null };

  constructor(props) {
    super(props);
    this.onSuccess = this.onSuccess.bind(this);
    this.onFail = this.onFail.bind(this);
    this.spinner = this.spinner.bind(this);
  }

  onSuccess() {
    const { navigation } = this.props;
    navigation.navigate('Auth');
  }

  onFail(reason) {
    Alert.alert(reason);
  }

  spinner() {
  //this is just a sample implementation, so copy pasting will not work as the components used below are custom
  //and are not in imports above. Please replace it with your implementation.
      return (
        <CView>
            <Spinner />
        </CView>
    );  
  }

  render() {
    return <LogoutView 
             onSuccess={this.onSuccess}
             onFail={this.onFail}
             renderLoading={this.spinner}
            />;
  }
}

Profile Edit screen

import React from 'react';
import { Alert } from 'react-native';
import { EditView } from 'ad-b2c-react-native';

export default class EditProfile extends React.PureComponent {
  static navigationOptions = { header: null };

  constructor(props) {
    super(props);
    this.onSuccess = this.onSuccess.bind(this);
    this.onFail = this.onFail.bind(this);
    this.spinner = this.spinner.bind(this);
  }

  onSuccess() {
    const { navigation } = this.props;
    navigation.navigate('Auth');
  }

  onFail(reason) {
    Alert.alert(reason);
  }

  spinner() {
  //this is just a sample implementation, so copy pasting will not work as the components used below are custom
  //and are not in imports above. Please replace it with your implementation.
      return (
        <CView>
            <Spinner />
        </CView>
    );  
  }

  render() {
    return <EditView 
             onSuccess={this.onSuccess}
             onFail={this.onFail}
             renderLoading={this.spinner}
            />;
  }
}

Routes

import {
  createStackNavigator,
  createAppContainer,
  createSwitchNavigator,
} from 'react-navigation';

import Home from './Home';
import Login from './Login';
import Logout from './Logout';
import EditProfile from './EditProfile';

const AuthStack = createStackNavigator({ Login });
const AppStack = createStackNavigator(
  {
    Home,
    EditProfile,
    Logout,
  }
);

const navigator = createSwitchNavigator(
  {
    App: AppStack,
    Auth: AuthStack,
  },
  {
    initialRouteName: 'Auth',
  },
);
const routes = createAppContainer(navigator);

Get Access Token

Call adService.getAccessTokenAsync() anywhere in your solution to get latest access token. The token is cached and if expired will use refresh token to get new one seamlessly. Make sure to await or use promise api to use the method.

import { adService } from 'ad-b2c-react-native';

const tokenResult = await adService.getAccessTokenAsync(); 
//tokenResult: {isValid: bool, data: string}
//tokenResult.data: string of format 'type accessToken', e.g Bearer sampleAccessToken

Get ID Token

The idToken is retrievable only after a successful login. Decode it using the library of choice to get user info

import { adService } from 'ad-b2c-react-native';

await adService.getIdToken();
