How to prepare a configuration.nix prior to installing NixOS (alien.top)

Hello, hope your all well?

So I'm about to install NixOS on my primary workstation. I've been tinkering on an old laptop, learning flakes, getting to grips with home-manager and the nix commands especially garbage collection.

So the configuration.nix I've created on my laptop, isn't all the tooling I'll use on my workstation and honestly, I can remember half the stuff I've installed or tools I install along the way.

So here is my actual question is there anything like a nix config generator, where I can cherry pick apps, services and utilities?

It's not NixOS I'm bothered about, it's all the stuff I've installed on Arch over the last few years - like yq, I use it once in a blue moon.

The main reason I'm switching to NixOS is that it has configuration.nix , flakes and home-manager. Put it like this a while back I struggled to get wasm containers working in docker, I did a lot of faffing including g I stalling extra binfmt's different wasm runtime, only to realise that wasm wasn't available in the version of docker I was using, so I installed beta, broke a whole load of stuff.

My core use case is if I break stuff then I can go back a gen or two. Which is what I've been trying out on an old spare laptop.

I'm pretty much upto speed on searching stable and u stable packages and option but thank anyway

Are you keeping nix config in git? Between generations and source control you should be covered.
