FaaS QR Code using C#

Inspired by John McCabe's qrcode function in Go, I made one in C#!

Deploying the function

Be sure to follow the instructions on the FaaS repo to deploy the Faas stack.

Get the CLI

You can install the faas-cli via brew install faas-cli or curl -sSL https://get.openfaas.com | sudo sh.

Build and deploy

Build and deploy your stack using the following commands:

$ faas-cli -action build -f ./stack.yml
$ faas-cli -action deploy -f ./stack.yml

Test

Using curl, you can send a URL (or any data) to the function to generate a QR code:

$ curl localhost:8080/function/qrcode -d 'http://get-faas.com' > qrcode.png

Voila! You have a QR code! You can check it via Android using this app.
