This sample is to demonstrate a chat application using the following cutting-edge technology stack :

• Angular as client which uses rsocket-js to communicate with the server side
• Spring WebFlux based RSocket server which uses WebSocket as transport protocol
• Spring Data MongoDB based @Tailable query result as an infinite stream

• NodeJS 14
• OpenJDK 14
• Docker for Windows/MacOS

Before running the application, you should build and run client and server side respectively.

Run a MongoDB service firstly, simply you can run it from a Docker container. There is a docker-compose.yaml file is ready for you.

docker-compose up mongodb

Build the application.

./gradlew build

Run the target jar from the build folder to start up the application.

java -jar build/xxx.jar

Install dependencies.

npm install

Start up the application.

npm run start

Open a browser and navigate to http://localhost:4200.
