Cryptocurrency PWA with Holdings Data in Okta

This example app shows how to use Okta's Java SDK to store cryptocurrency holdings as a custom user attribute.

Please read Use Okta (Instead of Local Storage) to Store Your User's Data Securely to see how this app was created. To see how it's tested, see The Hitchhiker's Guide to Testing Spring Boot APIs and Angular Components with WireMock, Jest, Protractor, and Travis CI.

Prerequisites: Java 8 and Node.js.

Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta's intuitive API and expert support make it easy for developers to authenticate, manage, and secure users and roles in any application.

Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-ionic-crypto-java-sdk.git
cd okta-ionic-crypto-java-sdk

This will get a copy of the project installed locally. To install all of its dependencies and start each app, follow the instructions below.

To run the server, cd into the holdings-api folder and run:

./mvnw spring-boot:run

To run the client, cd into the crypto-pwa folder and run:

npm install -g ionic
npm i && ionic serve

Setup Okta

The first thing you’ll need to do is add a holdings attribute to your organization’s user profiles. Log in to the Okta Developer Console, then navigate to Users > Profile Editor. Click on Profile for the first profile in the table. You can identify it by its Okta logo. Click Add Attribute and use the following values:

• Display name: Holdings
• Variable name: holdings
• Description: Cryptocurrency Holdings

You will need to create an API Token and OIDC App to get your values to perform authentication.

Log in to your Okta Developer account (or sign up if you don’t have an account) and navigate to Applications > Add Application. Click Single-Page App, click Next, and give the app a name you’ll remember. Click Done.

For the Okta Java SDK to talk to Okta’s API, you’ll need to create an API token. The abbreviated steps are as follows:

1. Log in to your Developer Console
2. Navigate to API > Tokens and click Create Token
3. Give your token a name, then copy its value

Server Configuration

Open holdings-api/src/main/resources/application.properties and add your API token as a property. While you're there, set the issuer and clientId to match your OIDC application.

NOTE: The value of {yourOktaDomain} should be something like dev-123456.oktapreview.com. Make sure you don't include -admin in the value!

okta.oauth2.issuer=https://{yourOktaDomain}.com/oauth2/default
okta.oauth2.clientId={yourClientId}
okta.client.token=XXX

Client Configuration

For the client, set the issuer and copy the clientId into src/pages/login/login.ts.

const config = {
  issuer: 'https://{yourOktaDomain}.com/oauth2/default',
  redirectUri: window.location.origin + '/implicit/callback',
  clientId: '{clientId}'
};
