Kotlin and TypeScript Notes Example

This example app shows how to build a basic notes app with Kotlin, Spring Boot, Spring Data, TypeScript, and Angular.

Please read Build a Secure Notes Application with Kotlin, TypeScript, and Okta to see how this app was created.

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-kotlin-typescript-notes-example.git
cd okta-kotlin-typescript-notes-example

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 server folder and run:

./mvnw

To run the client, cd into the client folder and run:

yarn && yarn start

Create an OIDC App in Okta

You will need to create an OIDC App in Okta to get a clientId.

Log in to your Okta Developer account (or sign up if you don’t have an account) and navigate to Applications and click on Add Application. Select Single Page App (SPA) and click Next. Give the application a name (e.g. “My OIDC App”) and specify http://localhost:4200 as a Login redirect URI. Click Done and admire your handiwork!

Server Configuration

Set the issuer and copy the clientId into server/src/main/resources/application.properties.

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

okta.oauth.issuer=https://{yourOktaDomain}.com/oauth2/default
okta.oauth.clientId={clientId}

Client Configuration

For the client, set the issuer and copy the clientId into client/src/app/shared/okta.service.ts.

signIn = new OktaSignIn({
  baseUrl: 'https://{yourOktaDomain}.com',
  clientId: '{clientId}',
  redirectUri: 'http://localhost:4200',
  authParams: {
    issuer: 'default',
    responseType: ['id_token', 'token'],
    scopes: ['openid', 'email', 'profile']
  }
});

NOTE: There’s one issue with Okta’s Sign-In Widget I still haven’t fully figured out. Not every time, but everyone once it in a while, it requires me to move my mouse or click on the screen to make the notes list load after logging in. I opened an issue for this, and tried the suggested solution, but it doesn’t work 100% of the time.
