In the tutorial, you’ll use the Ionic Framework’s UI components to create a Login page and a Home page within an Ionic Angular app. With just a few lines of code, you’ll secure the Home page by adding Auth0 login/logout functionality using the Auth Connect native plugin.
For reference, a complete demo app is available that serves as a companion to the Auth0 article.
Before integrating Auth Connect into your Ionic app, you’ll need to get Auth0 up and running. If you don’t have one already, create a free Auth0 account then head over to the Applications page and click the “Create Application” button. Give your new app a name, then choose “Native” for application type. Note the Domain and Client ID - you’ll need those later.
Next, choose your globally unique App Id, which is used both in Auth0 configuration as well as Cordova/Capacitor as well. Typically, this takes the form of “company-AppName” or reverse DNS style - “com.company.app.”
With that in hand, set the Allowed Callback URLs. After the app user signs into Auth0, this tells Auth Connect which page to redirect to in your app. Use the formula “uniqueId://page”, such as “company-AppName://callback.”
Similarly, set the Allowed Logout URLs, which tell Auth Connect where to redirect to after the user logs out of Auth0. Again, use the “uniqueId://page” format. Usually, the app would redirect the user to a login page, so consider using “company-AppName://login.”
Auth0 is now ready to use in your Ionic app.
Run the following command to install the Auth Connect plugin. For the
AUTH_URL_SCHEME variable, use the globally unique App Id (ex:
com.company.app) you decided on when configuring the Auth0 app above.
If you have not already setup Ionic Enterprise in your app, follow the one-time setup steps.
Next, install the plugin:
It's recommended to create an
AuthenticationService class that encapsulates Auth0 and Ionic Auth Connect’s login functionality.
Generate this class using the
ionic generate command:
IonicAuth class, then configure all Auth0 details in the
Some of these
IonicAuthOptions values are unique, and must be set based on your Auth0 app’s details:
platform: Use “cordova” or “capacitor” accordingly.
clientID: Your app’s Client ID.
discoveryUrl: Consists of your Auth0 Domain plus “.well-known/openid-configuration”. Example: https://ionicorg.auth0.com/.well-known/openid-configuration
redirectUri: The URI to redirect to after the user has logged in. Use the same AUTH_URL_SCHEME variable value (App Id) from when the Auth Connect plugin was installed. Example: com.company.app://callback
logoutUrl: The URI to redirect to after the user has logged out. Example: com.company.app://login?logout=true
The Discovery URL can be found under Application Details -> Show Advanced Settings -> Endpoints tab:
