Introduction

The Backend (RX Observable)

Hot Observable

• constantly streams events, at short intervals (but unreliable maybe skipping information)
• allows multiple consumers

The UI (ZK MVVM application)

• render robots as divs + dynamic styles reacting on robot status (position, mood)

The Magic in the Middle

• filter the events (by selectable criteria)
• throttle UI updates (reducing the network load)
  • buffer updates (100ms / 1000ms)
  • avoid redundant updates
  • batch update (in a single ZK execution)

Summary

Example Sources

The code examples are available on github in the zk-rxdemo repository

Running the Example

Clone the repo

   git clone git@github.com:zkoss-demo/zk-rxdemo.git

The example war file can be built using the gradle-wrapper (on windows simply omit the prefix './'):

   ./gradlew war

Execute using jetty-runner (fastest):
