Everyone loves a good “how I set up my blog post” blog post, so here’s mine, using Elixir, Phoenix, and NimblePublisher. For added spice it’s running on Dokploy on Hetzner, with bunny.net in front as a CDN.

As someone who had a lot of initial interest in Hologram, I’m only just diving into it now. It’s feeling magical being able to write Elixir in the template and have it update on the client. I’m still getting used to it (in a good way).
