Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-ionic-crypto-pwa-example.git
cd okta-ionic-crypto-pwa

This will get a copy of the project installed locally. Then run the following command to install Ionic.

npm install -g ionic

Then run the application:

npm install
ionic serve

To integrate Okta's Identity Platform for user authentication, you'll first need to:

• Register and create an OIDC application
• Log in to your Okta account and navigate to Applications > Add Application
• Select SPA and click Next
• Give your application a name (e.g. "Crypto PWA")
• Change the Base URI, Login redirect URI, and Logout redirect URI to http://localhost:8100 and click Done.

After performing these steps, copy the clientId into src/pages/login/login.ts and change {yourOktaDomain} to match your account's id.

constructor(private oauthService: OAuthService, private app: App) {
  if (this.oauthService.hasValidIdToken()) {
    this.app.getRootNavs()[0].setRoot('HomePage');
  }

  oauthService.redirectUri = window.location.origin;
  oauthService.clientId = '{clientId}';
  oauthService.scope = 'openid profile email';
  oauthService.issuer = 'https://{yourOktaDomain}/oauth2/default';
  oauthService.tokenValidationHandler = new JwksValidationHandler();
  oauthService.loadDiscoveryDocumentAndTryLogin();
}

Your OIDC app should have settings like the following:
