Move name on screen and update background image.
Yes, JS. run the server and open http://localhost:8000, connect a badge, enjoy.
This commit breaks down the `Main` file to multiple different files each represents a specific part of the backend (e.g., model, route, etc...)

Overall makes sense, but I'd still recommend to look at this:
https://www.cloudflare.com/application-services/products/ssl/
If you point DNS to there, you can get HTTP>HTTPS redirections for free, plus image caching for free… and the app can always run in non-SSL mode (plus you get a free cert rotation by Cloudflare). 🤷♂️

Hey, thanks for the review, I'll talk about the specific things in a minute, on individual comments. BUT: I am using cloudflare to generate the SSL certificate (That then gets transformed from PEM to PKCS to then JKS to be delivered by the webserver). Or do you mean anything different, that I might (:scream:) not understand yet? |
I will merge it for now, it is getting to big for me to handle. If there are more changes, let us do them individually... |
What I meant was, you can do some port forwarding and never worry about SSL in the service itself :) E.g. [ Client ] -> DNS fetch -> request https://host:ip/endpoint This way the service always run in HTTP mode and you pretend certificates don't exist. The same is achievable with cert rotator attached to k8s ingress, and I've done it in docker in the past too 🗡️ (but docker requires the whole server to run docker only, so that you can proxy requests through a single container to all other containers) Not sure if that was clear 😄 yours works too, probably™. Just saying it could be simpler |
Summary
Provide code for a Webserver (ktor) that builds an API that access the badge image creation libraries and facilities. See it running as https://zebadge.app .
It's hosted as a cloud function on Google, using Google's/Squarespace custom domain and cloudflares DNS for SSL. To update, ssh into cloud function, update git, rerun server.
Currently @mariobodemann is paying for hosting.
When opened, the website displays a form with name and contact, including size and color. Once this form is changed, the badge will get drawn using a js 2d canvas. Alternatively a background image can get selected. Upon changes a new request is send to the API, returning a PNG that is also drawn next to the badge.
Once happy with the badge the use can connect ZeBadge and press the "sent" button to create the serial data thought the API that needs to be sent to the badge.
Once sending is done, the digital badge will be updated, showing the new data.
How It Was Tested
It was tested two ways:
./gradlew server:run --args="8000"
. Upon connecting chrome, or edge to the localhost:8000 address, the certificate error gets ignored. The website can now be fully used and some names were changed and the result was uploaded to ZeBadge.Screenshot/Gif
base badge test
background image test
Success
