Realised with Fresh framework. You can follow the Fresh "Getting Started" guide here: https://fresh.deno.dev/docs/getting-started
Make sure to install Deno: https://deno.land/manual/getting_started/installation
Then start the project:
deno task start
I used the Deno Deploy (https://deno.com/deploy) to host the project, that's so easy. You can check it here https://hugomalzieux.deno.dev
