Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together 

hardware devices, APIs and online services as part of the Internet of Things.

Node-RED provides a web browser-based flow editor, which can be used to create JavaScript functions. 

Elements of applications can be saved or shared for re-use. The runtime is built on Node.js. 

The flows created in Node-RED are stored using JSON. Since version 0.14, MQTT nodes can make properly 

configured TLS connections.
