Node-RED

This node is part of project node-red-contrib-viseo powered by VISEO Technologies. Please find the node documentation in the Node-RED info tab.

Here is a French Article on Bot Ecosystem and more.

Quick Start

npm install node-red-contrib-viseo-qrcode

Build the Node-RED Flow

The qrDecode node

  • retrieve a Buffer or an URL from the given input,
  • if it's an URL, download the Buffer
  • retrieve and decode the Buffer QRCode
  • parse encoded data to a JSON object
  • If data is an URL, convert it's querystring to a JSON object

Best Practices

ZXing webservice can be use to generate a QRCode.

Generated QRCode should contains an URL with parameters.

  • Anyone using the QRCode will be redirected to that URL (that could explain the webservice)
  • Decoding the QRCode will still works
