Getting Started

What's this?

A Spring Boot 2.2 reactive application to be used as an RSocket demo, including the following features:

  • Java RSocket server
  • Java RSocket client
  • Javascript RSocket client

The Java backend exposes the following APIs:

  • HTTP http://localhost:8080/socket/{author} : the HTTP request triggers the Java RSocket client to pull data from the Java RSocket server
  • HTTP http://localhost:8080/tweets/{author} : the same API as above but without any socket interaction, pure SSE over HTTP
  • WS ws://localhost:8080/tweetsocket - route: tweets.by.author : WebSocket transport employed by the Javascript RSocket client to pull data from the Java RSocket server

The Javascript client can be used by requesting http://localhost:8080/index.html

*the possible {author} values are linustorvalds, robertmartin, martinfowler.

Quickstart

Spin up both the backend and the frontend by running: mvn spring-boot:run.

NOTE: when started this way, the demo will try to run an Embedded Redis Server instance on the specified port. If a Redis Server instance is already running on your machine you can either a) change the specified redis port in the application.yml file, or b) run the demo with the prod profile enabled, which disables the Embedded Redis Server (eg. mvn spring-boot:run -Dspring-boot.run.profiles=prod).

Running with Docker

...or if you want, you can run the app within docker by running: docker-compose up

(this will use a dockerized Redis server rather than embedded Redis!)
