# services-flake

NixOS-like services for Nix flakes, as a [process-compose-flake](https://github.com/Platonic-Systems/process-compose-flake) module (based on flake-parts).

## Getting Started

```sh
$ nix flake new --template github:juspay/services-flake ./my-project
$ cd my-project
$ nix run
```

Or see `./test/flake.nix`

## Services available

See the list [here](nix/default.nix).

## A note on process working directory

The `dataDir` of these services tend to take *relative* paths, which are usually relative to the project root. As such, when you run these services using `nix run`, their data files are created relative to whichever directory you are in. If you want these data files to always reside relative to the project directory, instead of using `nix run` consider wrapping the process-compose packages in script, via either [mission-control](https://community.flake.parts/mission-control) module or a [justfile](https://just.systems/). The example uses the latter.

## Credits

Thanks to [the devenv project](https://github.com/cachix/devenv/tree/main/src/modules/services) on which much of our services implementation is based on.

## FAQ

### Why not re-use devenv service modules?

This is currently not possible (nor prioritized by the devenv project), which is why we must create our own services. See https://github.com/cachix/devenv/issues/75
