practical-flakes-template

Description

PracticalFlakes are a set of highly opinionated templates to quickly bootstrap your next nix project in flakes 😎

To quickly initialize a new project run

nix flake init -t github:tsandrini/practical-flakes-template

And you're good to go! 👍

Features

1. Drop-in modularity using flake-parts ⚙️
   • the main idea is that if you have a bunch of projects using this template you can simply just copy the individual parts/ directories to share functionality
   • this way, no matter if you're developing language features, packages, NixOS modules, home-manager userspace, you can always use the same underlying structure
2. devenv.sh is awesome! 🔥
   • includes a devenv shell already preconfigured to format and lint nix
3. treefmt is the one and only formatter to rule them all 🙏
4. Already preconfigured github actions and gitlab CI 💪
   • automatic nix flake check on pull/merge requests
   • automatic nixpkgs flake inputs checker (github only)
   • automatic cron based flake inputs updates (github only)
   • (optional) push to FlakeHub
5. Prepared for custom lib overrides 🤓
   • depending on what you're currently aiming to write, you might need some custom helpers or library functions, this template already set ups all the necessary boilerplate to get it all going
6. And finally, examples included 🖌️

Usage

After a proper installation process you can enter the development environment with direnv allow (or alternatively nix develop .#dev --override-input devenv-root "file+file://"<(printf %s "$PWD"))

While not many, the code has some required references to the practicalFlakes identifier. This can be renamed in the whole project using the script rename-project (which is available in the dev environment)

rename-project . myAwesomeApp

You're also encouraged to update your flakes with

nix flake update

Variants

There are also a few other different variants of the base template that may be better suited for your needs

• main: The main, default template.
• home: Conceptually and structurally the same as the default template, but also includes prepared and preconfigured home-manager as well as examples of how to use it
• minimal: Structurally the same as the default template, but stripped of all of the included examples and additional prepared files
• isolated: Centralizes all of the nix related stuff into a nix/ folder. This can be useful when you'd like to not pollute your root with stuff not directly tied to the code.
• isolated-minimal: Isolated combined with minimal, that is, structurally the same as minimal, however, stripped out of all the examples and unnecessary code

You can install your desired template variant using

nix flake init -t github:tsandrini/practical-flakes-template#myVariant

For example, nix flake init -t github:tsandrini/practical-flakes-template#isolated-minimal.
