 [FLaNK] Smart Weather Websocket Application - Kafka Consumer Part 2 of 2 This is based on Koji Kawamura's excellent GIST:  https://gist.github.com/ijokarumawak/60b9ab2038ef906731ebf4c0eee97176 As part of my Smart Weather Application, I wanted to display weather information as it arrives in a webpage using web sockets.   Koji has an excellent NiFi flow that does it.   I tweaked it and add some things since I am not using Zeppelin.   I am hosting my webpage with NiFi as well. https://www.datainmotion.dev/2020/11/flank-smart-weather-applications-with.html We simply supply a webpage that makes a websocket connection to NiFi and NiFi keeps a cache in HBase to know what the client is doing.  This cache is updated by consuming from Kafka.   We can then feed events as they happen to the page. Here is the JavaScript for the web page interface to websockets: <script> function sendMessage(type, payload) { websocket.send(makeMessage(type, payload)); } function makeMessage(type, payload
