linomp / svelte-qr-mqtt

Proof of concept: a Svelte app with in-browser QR code generation + interaction through a smartphone (using MQTT over websockets).

svelte-qr-mqtt

A simple Svelte app that creates a QR code to be scanned with a smartphone. This opens another page on the phone, with a couple of buttons that trigger actions on the original page (via MQTT).

Try it out: Live demo

Setup

See the .env files for broker configuration.

Currently, the broker listed there is a public Mosquitto MQTT broker provided by Eclipse for testing (supports MQTT over secure web sockets).
