Technologies Used in FaaSO

FaaSO itself is pretty small, and that's because it uses a ton of stuff that already exists. This page documents what some of those things are, and why.

Language

I used Crystal because it's nice, fast, has a good standard library, and is statically typed.

Website

It's done using Nicolino because I wrote it and wanted to use it. It's a static site generator.

The theme uses Pico CSS which is awesome and understandable for a non-frontender like me and a ton of other things, like Highlight.js and Discount.

The videos would not be possible without Asciinema and Doitlive.

Platform

• Docker everywhere, because it's what I know.
• Linux, because it's really what Docker runs on.
• Alpine Linux to build the containers, because they are small.
• GitHub, for hosting the code, and building stuff, and the container registry, and the issue manager, and ...
• QEmu: to build cross-platform stuff.
• Caddy for the reverse proxy.
• TtyD for the terminal on a website.
• HTMX for making the frontend possible at all.

Too many things, really. It's a miracle to live in a moment where all these cool things are there, ready to be used. I used to live in a world where NONE OF THIS EXISTED (it was called the 80s) and it was extremely boring.
