CLI application that takes an url ? and generates a Qr code

qr -o qr.png "https:google.com"

• create CLI
• Parse flags
• Generate a qr (qr library)
• save to file

Evolve this to a HTTP server which exposes an endpoint that takes the same url and returns an image of the qr code

• HTTP server
• URL parsing
• Maybe add a router ?
• Extract parameter
• Return an image

qr -u "https://google.com" -o image.png

qr -server 

• CLI has a new flag that runs in server mode
• Server mode exposes an endpoint that takes a url and brings back a QR image
• We want the API responses to be similar to https://placehold.co/ i.e if you put the url in an tag the browser should be able to render the qr code just fine

• ✅ Creating an HTTP server
• ✅ Extract the url from the endpoint.
• ✅ Adding additional "server-mode" flag to the CLI.
• ✅ Reuse the existing qr generation logic to return the image.
• ✅ Proper test http (instead of using phone).
• ✅ Add Tests & re-structure the code to make it more testable.
• ✅ Refactor to split things in different files with a logical flow.
• Embed html for a UI for adding the URL.

• Define the service GRPC
