Weblink Console and printer "application" demo tool. "application" here has a very specific meaning:
- a set of SGD configuration commands that redirect to cloud a specific input channel (USB, BT, SERIAL) - technically a list of JSON-SGD commands (typically a capture channel to variable and SGD-variable-change-alert setup)
- some logic in the server that processes the alert and does something with it - technically an async computation expression that takes a string to a new string
The 4 "applications" built into the server stem from 4 real-life use-cases where printer-redirected data is augmented / formatted appropriately before printing
- printing price labels (repricing) using ZQ label printer with Wifi and BT + CS4070 BT scanner
- convertion of a legacy label received via USB into a new label preserving variable data
- self-service label printing in parcel shops for return of goods purchased online
- convertion of SVG label (dpi independent) into ZPL (TO BE IMPLEMENTED)

- One wss / sse / https server written in F#/Suave
- One HTML5 SPA to monitor websocket channels and send commands onto the printer channels (HTML / JAVASCRIPT)
Deployed to AWS EC2 - Docker running on a Linux AMI instance- . Amazon ALB terminates the HTTPS channel.
