Getting Started with Auth Connect

Generate the Application

Before we explore the use of Auth Connect, we need to scaffold an application. In this section, we will generate an @ionic/react tabs based application, perform some basic configuration, and add the iOS and Android platforms.

Terminal


_10ionic start getting-started-ac tabs --type=react

Use the Ionic CLI to generate the application.

Terminal


_10ionic start getting-started-ac tabs --type=react
_10cd getting-started-ac

Change directory into the newly generated project.

Terminal

capacitor.config.ts


_12import { CapacitorConfig } from '@capacitor/cli';
_12
_12const config: CapacitorConfig = {
_12  appId: 'io.ionic.gettingstartedac',
_12  appName: 'getting-started-ac',
_12  webDir: 'dist',
_12  server: {
_12    androidScheme: 'https',
_12  },
_12};
_12
_12export default config;

Change the appId to be something unique. The appId is used as the bundle ID / application ID. Therefore it should be a string that is unique to your organization and application. We will use io.ionic.gettingstartedac for this application.

It is best to do this before adding the iOS and Android platforms to ensure they are setup properly from the start.

Terminal

capacitor.config.ts


_10ionic start getting-started-ac tabs --type=react
_10cd getting-started-ac
_10npm run build
_10ionic cap add android
_10ionic cap add ios

Build the application and install the platforms.

Terminal

capacitor.config.ts

package.json


_15{
_15  "name": "getting-started-ac",
_15  "version": "0.0.1",
_15  "author": "Ionic Framework",
_15  "homepage": "https://ionicframework.com/",
_15  "scripts": {
_15    "dev": "vite",
_15    "build": "tsc && vite build && cap sync",
_15    "preview": "vite preview",
_15    "test.e2e": "cypress run",
_15    "test.unit": "vitest",
_15    "lint": "eslint"
_15  },
_15  ...
_15}

We should do a cap sync with each build. This ensures our native projects remain up to date. Change the scripts in package.json to do this.

Terminal

capacitor.config.ts

package.json

vite.config.ts


_16import legacy from '@vitejs/plugin-legacy';
_16import react from '@vitejs/plugin-react';
_16import { defineConfig } from 'vite';
_16
_16// https://vitejs.dev/config/
_16export default defineConfig({
_16  plugins: [react(), legacy()],
_16  server: {
_16    port: 8100,
_16  },
_16  test: {
_16    globals: true,
_16    environment: 'jsdom',
_16    setupFiles: './src/setupTests.ts',
_16  },
_16});

Modify the vite.config.ts file to ensure that the development server (npm run dev) uses port 8100.

Use the Ionic CLI to generate the application.

Change directory into the newly generated project.

Install Auth Connect

In order to install Auth Connect, you will need to use ionic enterprise register to register your product key. This will create a .npmrc file containing the product key.

If you have already performed that step for your production application, you can just copy the .npmrc file from your production project. Since this application is for learning purposes only, you don't need to obtain another key.

You can now install Auth Connect and sync the platforms:

Terminal


_10npm install @ionic-enterprise/auth
_10npx cap sync

Create the "Session Store"

When using Auth Connect, the current session is defined by the current AuthResult which contains auth tokens as well as other session information. Auth Connect returns an AuthResult from the login() function. We will need a place to store that result. Let's create that now. Create a src/util directory, then create a file called src/util/session-store.ts.

Note: React allows for many different state management strategies. Your strategy may differ significantly. State management strategies are outside the scope of this tutorial. Use code that aligns with your chosen strategy.

src/utils/session-store.ts


_10import { AuthResult } from '@ionic-enterprise/auth';
_10
_10let session: AuthResult | null = null;

We know we will need to store the session, and that the session is defined by the AuthResult.

src/utils/session-store.ts


_11import { AuthResult } from '@ionic-enterprise/auth';
_11
_11let session: AuthResult | null = null;
_11let listeners: any[] = [];
_11
_11const subscribe = (listener: any) => {
_11  listeners = [...listeners, listener];
_11  return () => {
_11    listeners = listeners.filter((l) => l !== listener);
_11  };
_11};

To sync the store with React, we will eventually use useSyncExternalHook. In preparation, we need some boilerplate code starting with a subscribe() method.

src/utils/session-store.ts


_15import { AuthResult } from '@ionic-enterprise/auth';
_15
_15let session: AuthResult | null = null;
_15let listeners: any[] = [];
_15
_15const subscribe = (listener: any) => {
_15  listeners = [...listeners, listener];
_15  return () => {
_15    listeners = listeners.filter((l) => l !== listener);
_15  };
_15};
_15
_15const getSnapshot = (): AuthResult | null => {
_15  return session;
_15};

Add a getSnapshot() function that just returns the current session.

src/utils/session-store.ts


_21import { AuthResult } from '@ionic-enterprise/auth';
_21
_21let session: AuthResult | null = null;
_21let listeners: any[] = [];
_21
_21const subscribe = (listener: any) => {
_21  listeners = [...listeners, listener];
_21  return () => {
_21    listeners = listeners.filter((l) => l !== listener);
_21  };
_21};
_21
_21const getSnapshot = (): AuthResult | null => {
_21  return session;
_21};
_21
_21const emitChange = () => {
_21  for (let listener of listeners) {
_21    listener();
_21  }
_21};

When the session changes, we need to inform any subscribed listeners.

src/utils/session-store.ts


_26import { AuthResult } from '@ionic-enterprise/auth';
_26
_26let session: AuthResult | null = null;
_26let listeners: any[] = [];
_26
_26const subscribe = (listener: any) => {
_26  listeners = [...listeners, listener];
_26  return () => {
_26    listeners = listeners.filter((l) => l !== listener);
_26  };
_26};
_26
_26const getSnapshot = (): AuthResult | null => {
_26  return session;
_26};
_26
_26const emitChange = () => {
_26  for (let listener of listeners) {
_26    listener();
_26  }
_26};
_26
_26const setSession = (newSession: AuthResult | null) => {
_26  session = newSession;
_26  emitChange();
_26};

We need a function that we can use to set the session. For now, this is the only function that changes the session and emits the change.

src/utils/session-store.ts


_28import { AuthResult } from '@ionic-enterprise/auth';
_28
_28let session: AuthResult | null = null;
_28let listeners: any[] = [];
_28
_28const subscribe = (listener: any) => {
_28  listeners = [...listeners, listener];
_28  return () => {
_28    listeners = listeners.filter((l) => l !== listener);
_28  };
_28};
_28
_28const getSnapshot = (): AuthResult | null => {
_28  return session;
_28};
_28
_28const emitChange = () => {
_28  for (let listener of listeners) {
_28    listener();
_28  }
_28};
_28
_28const setSession = (newSession: AuthResult | null) => {
_28  session = newSession;
_28  emitChange();
_28};
_28
_28export { subscribe, getSnapshot, setSession };

Export the functions that will need to be used elsewhere in our application.

Create the `Authentication` Utility Functions

All interaction with Auth Connect will be abstracted into a set of functions in an authentication utility module. Create an empty src/utils/authentication.ts file.

Setup and Initialization

Before we use Auth Connect, we need to make sure that it is properly set up and initialized. We will build a utility function to perform the setup and initialization required by Auth Connect.

src/utils/authentication.ts


_10import { Capacitor } from '@capacitor/core';
_10
_10const isNative = Capacitor.isNativePlatform();

Auth Connect needs a slightly different configuration between mobile and web, so we need to know in which context we are currently running.

src/utils/authentication.ts


_10import { Capacitor } from '@capacitor/core';
_10import { Auth0Provider } from '@ionic-enterprise/auth';
_10
_10const isNative = Capacitor.isNativePlatform();
_10const provider = new Auth0Provider();

For this tutorial, we are using Auth0 as the authentication vendor. We need to create an Auth0Provider to help Auth Connect with the communication with Auth0.

src/utils/authentication.ts


_19import { Capacitor } from '@capacitor/core';
_19import { Auth0Provider, ProviderOptions } from '@ionic-enterprise/auth';
_19
_19const isNative = Capacitor.isNativePlatform();
_19const provider = new Auth0Provider();
_19
_19const authOptions: ProviderOptions = {
_19  audience: 'https://io.ionic.demo.ac',
_19  clientId: 'yLasZNUGkZ19DGEjTmAITBfGXzqbvd00',
_19  discoveryUrl:
_19    'https://dev-2uspt-sz.us.auth0.com/.well-known/openid-configuration',
_19  logoutUrl: isNative
_19    ? 'io.ionic.acdemo://auth-action-complete'
_19    : 'http://localhost:8100/auth-action-complete',
_19  redirectUri: isNative
_19    ? 'io.ionic.acdemo://auth-action-complete'
_19    : 'http://localhost:8100/auth-action-complete',
_19  scope: 'openid offline_access email picture profile',
_19};

Auth Connect needs to know how to communicate with our authentication vendor. You will likely need to get this information from the team that manages your cloud infrastructure.

_32    ios: { webView: 'private' },
_32    web: { uiMode: 'popup', authFlow: 'PKCE' },
_32  });
_32};

We need to perform a one-time setup with Auth Connect. Please refer to the documentation if you have any questions about the individual properties. We will start here with a simple set up that is good for development.

The utility module needs to return the setupAuthConnect function. It will be called elsewhere.

_35  });

_35export { setupAuthConnect };

Handling the Authentication Flow

Now that the utility functions are complete, we will use them to implement the authentication flow of our application. To do this, we will need to:

Create the AuthActionCompletePage and route that is used in our configuration.
Expose the authentication state to our application via the creation of an AuthenticationProvider.
Add buttons to the Tab1 page that will be used to perform the login() and logout() operations.

Create the `AuthActionCompletePage`

The logoutUrl and redirectUri properties are using the /auth-action-complete route. Create a page for the route. The page does not have to do much. We will just display a spinner in case someone sees it momentarily.

src/pages/AuthActionCompletePage.tsx


_13import { IonContent, IonPage, IonSpinner } from '@ionic/react';
_13import './AuthActionCompletePage.css';
_13
_13const AuthActionCompletePage: React.FC = () => (
_13  <IonPage>
_13    <IonContent className="main-content auth-action-complete">
_13      <div className="container">
_13        <IonSpinner name="dots" />
_13      </div>
_13    </IonContent>
_13  </IonPage>
_13);
_13export default AuthActionCompletePage;

We will perform a small bit of styling to make the page look nice.

src/pages/AuthActionCompletePage.css


_10.auth-action-complete .container {
_10  text-align: center;
_10  position: absolute;
_10  left: 0;
_10  right: 0;
_10  top: 50%;
_10  transform: translateY(-50%);
_10}

Be sure to add the route in the router setup. In a production app, this likely would not be put within the IonTabs structure. Refactoring the routing, however, to avoid this is beyond the scope of this tutorial.

Create the `AuthenticationProvider`

The Auth Connect related functionality will be exposed to our application via a context provider, which we will now build. Create a src/providers directory containing a file named src/providers/AuthenticationProvider.tsx

src/providers/AuthenticationProvider.tsx


_10import { createContext } from 'react';
_10
_10type Context = {
_10  isAuthenticated: boolean;
_10};
_10
_10export const AuthenticationContext = createContext<Context>({
_10  isAuthenticated: false,
_10});

Start with creating the context we want to provide to the application.

src/providers/AuthenticationProvider.tsx


_21import { PropsWithChildren, createContext, useState } from 'react';
_21
_21type Context = {
_21  isAuthenticated: boolean;
_21};
_21
_21export const AuthenticationContext = createContext<Context>({
_21  isAuthenticated: false,
_21});
_21
_21export const AuthenticationProvider: React.FC<PropsWithChildren> = ({
_21  children,
_21}) => {
_21  const [isAuthenticated, setIsAuthenticated] = useState(false);
_21
_21  return (
_21    <AuthenticationContext.Provider value={{ isAuthenticated }}>
_21      {children}
_21    </AuthenticationContext.Provider>
_21  );
_21};

Create a shell component for the AuthenticationProvider. It needs to render the context we created.

src/providers/AuthenticationProvider.tsx


_28import { IonSpinner } from '@ionic/react';
_28import { PropsWithChildren, createContext, useEffect, useState } from 'react';
_28import { setupAuthConnect } from '../utils/authentication';
_28
_28type Context = {
_28  isAuthenticated: boolean;
_28};
_28
_28export const AuthenticationContext = createContext<Context>({
_28  isAuthenticated: false,
_28});
_28
_28export const AuthenticationProvider: React.FC<PropsWithChildren> = ({
_28  children,
_28}) => {
_28  const [isAuthenticated, setIsAuthenticated] = useState(false);
_28  const [isSetup, setIsSetup] = useState(false);
_28
_28  useEffect(() => {
_28    setupAuthConnect().then(() => setIsSetup(true));
_28  }, []);
_28
_28  return (
_28    <AuthenticationContext.Provider value={{ isAuthenticated }}>
_28      {isSetup ? children : <IonSpinner />}
_28    </AuthenticationContext.Provider>
_28  );
_28};

Initialize AuthConnect. The child components should only be able to interact with AuthConnect after it has completed the initialization process, so display a spinner until this is complete.

src/providers/AuthenticationProvider.tsx


_40import { IonSpinner } from '@ionic/react';
_40import {
_40  PropsWithChildren,
_40  createContext,
_40  useEffect,
_40  useState,
_40  useSyncExternalStore,
_40} from 'react';
_40import { setupAuthConnect } from '../utils/authentication';
_40import { getSnapshot, subscribe } from '../utils/session-store';
_40
_40type Context = {
_40  isAuthenticated: boolean;
_40};
_40
_40export const AuthenticationContext = createContext<Context>({
_40  isAuthenticated: false,
_40});
_40
_40export const AuthenticationProvider: React.FC<PropsWithChildren> = ({
_40  children,
_40}) => {
_40  const [isAuthenticated, setIsAuthenticated] = useState(false);
_40  const [isSetup, setIsSetup] = useState(false);
_40  const session = useSyncExternalStore(subscribe, getSnapshot);
_40
_40  useEffect(() => {
_40    setupAuthConnect().then(() => setIsSetup(true));
_40  }, []);
_40
_40  useEffect(() => {
_40    setIsAuthenticated(!!session);
_40  }, [session]);
_40
_40  return (
_40    <AuthenticationContext.Provider value={{ isAuthenticated }}>
_40      {isSetup ? children : <IonSpinner />}
_40    </AuthenticationContext.Provider>
_40  );
_40};

Get the session value from our session store and update isAuthenticated when its value changes.

Start with creating the context we want to provide to the application.

Create a shell component for the AuthenticationProvider. It needs to render the context we created.

Initialize AuthConnect. The child components should only be able to interact with AuthConnect after it has completed the initialization process, so display a spinner until this is complete.

Get the session value from our session store and update isAuthenticated when its value changes.

src/providers/AuthenticationProvider.tsx


_10import { createContext } from 'react';
_10
_10type Context = {
_10  isAuthenticated: boolean;
_10};
_10
_10export const AuthenticationContext = createContext<Context>({
_10  isAuthenticated: false,
_10});

Now that the AuthenticationProvider has been created, we can add it to our application, which will allow us to perform the login and logout actions. Modify src/App.tsx to surround the bulk of our application with the provider.

Test this in the web using the following credentials:

email: test@ionic.io
password: Ion54321

At this point if we press the Login button, a tab should open where we can log in using Auth0. This tab will close after we log in. When we press the logout button a tab will briefly open to perform the logout and then automatically close. The button that is displayed changes based on our current authentication status.

Configure the Native Projects

Login and logout are working in your web browser. Build your application for mobile and try to run them there. You can use an emulator or an actual device for this test.

Terminal


_10npm run build
_10npx cap open android
_10npx cap open ios

On Android you are not returned to the application after logging in. You seem to be stuck at the Auth0 login page. On iOS you get an invalid URL error after successfully logging in on Auth0.

The problem is that on mobile we are deep-linking back into our application using io.ionic.acdemo://auth-action-complete. We have not registered that scheme with the OS so it does not know to deep-link back to our application. We will set that up now.

For Android, modify the android/variables.gradle file to include the AUTH_URL_SCHEME value:

app/variables.gradle


_17ext {
_17    minSdkVersion = 22
_17    compileSdkVersion = 34
_17    targetSdkVersion = 34
_17    AUTH_URL_SCHEME = 'io.ionic.acdemo'

For iOS, add a CFBundleURLTypes section to the ios/App/App/Info.plist file:

App/App/Info.plist


_58<?xml version="1.0" encoding="UTF-8"?>
_58<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
_58<plist version="1.0">
_58  <dict>
_58    <key>CFBundleDevelopmentRegion</key>
_58    <string>en</string>
_58    <key>CFBundleDisplayName</key>
_58    <string>getting-started-ac</string>
_58    <key>CFBundleExecutable</key>
_58          <string>io.ionic.acdemo</string>

Re-run the application from Xcode and Android Studio. You should now be able to perform the authentication properly on the mobile applications.

Persist the `AuthResult`

The user can perform login and logout operations, but if the browser is refreshed, the application loses the AuthResult. This value needs to be persisted between sessions of the application. To fix this, we will modify our session store to use the Preferences plugin to persist the AuthResult. In a production application, we should store the result more securely by using Identity Vault. However, setting up Identity Vault is beyond the scope of this tutorial.

Terminal


_10npm install @capacitor/preferences

Use the @capacitor/preferences in our session store to persist the AuthResult we received when logging in.

src/utils/session-store.ts

src/main.tsx


_28import { AuthResult } from '@ionic-enterprise/auth';
_28
_28let session: AuthResult | null = null;
_28let listeners: any[] = [];
_28
_28const subscribe = (listener: any) => {
_28  listeners = [...listeners, listener];
_28  return () => {
_28    listeners = listeners.filter((l) => l !== listener);
_28  };
_28};
_28
_28const getSnapshot = (): AuthResult | null => {
_28  return session;
_28};
_28
_28const emitChange = () => {
_28  for (let listener of listeners) {
_28    listener();
_28  }
_28};
_28
_28const setSession = (newSession: AuthResult | null) => {
_28  session = newSession;
_28  emitChange();
_28};
_28
_28export { subscribe, getSnapshot, setSession };

Currently, the session information is only stored in the session variable. We will modify our code to store the session information using the Preferences plugin.

src/utils/session-store.ts

src/main.tsx


_29import { AuthResult } from '@ionic-enterprise/auth';
_29import { Preferences } from '@capacitor/preferences';
_29
_29let session: AuthResult | null = null;
_29let listeners: any[] = [];

_29    listeners = listeners.filter((l) => l !== listener);
_29  };

_29const getSnapshot = (): AuthResult | null => {
_29  return session;

_29    listener();
_29  }

_29  session = newSession;
_29  emitChange();
_29};
_29
_29export { subscribe, getSnapshot, setSession };

Import the Preferences plugin.

src/utils/session-store.ts

src/main.tsx


_30import { AuthResult } from '@ionic-enterprise/auth';
_30import { Preferences } from '@capacitor/preferences';
_30
_30let session: AuthResult | null = null;

_30  }
_30};
_30
_30const setSession = async (newSession: AuthResult | null) => {
_30  session = newSession;
_30  await Preferences.set({ key: 'session', value: JSON.stringify(newSession) });
_30  emitChange();
_30};
_30
_30export { subscribe, getSnapshot, setSession };

Save the session to Preferences when the session is set.

Create an initialize() function that gets the value from the Preferences plugin.

src/utils/session-store.ts

src/main.tsx


_14import React from 'react';
_14import { createRoot } from 'react-dom/client';
_14import App from './App';
_14import { initialize } from './utils/session-store';
_14
_14const container = document.getElementById('root');
_14const root = createRoot(container!);
_14initialize().then(() =>
_14  root.render(
_14    <React.StrictMode>
_14      <App />
_14    </React.StrictMode>
_14  )

Ensure the authentication information is initialized before the application is mounted.

Currently, the session information is only stored in the session variable. We will modify our code to store the session information using the Preferences plugin.

Import the Preferences plugin.

Save the session to Preferences when the session is set.

If the user logs in and either refreshes the browser or restarts the application the authentication state is preserved.
