Frappix (preview)


Frappix bridges the gap between system depedencies and such that are already available in Python.

It brings the power of the entire software ecosystem to Frappe, not only the Python ecosystem.

It achieves this by plugging into one of the biggest software repositories to date.

System dependencies are declared by their identifier in pyproject.toml and are then mapped to their available implementation from the backing software repository.

When a user wants to start working on a project wired with Frappix, it is guaranteed for him to be productive at exactly on command away. Furthermore, the exact same environment used for development is recycled to produce a variety of production grade runtime artifacts, such as:

  • MicroVMs
  • VMs
  • Entire Host Operating System (fully configured)
  • OCI Containers

Whatever deployment scenario can be supported by this infrastructure.

The purpose, hence, of this work is to expand the unified expierience of the frappe ecosystem beyond its current boundary which it inherits from its language ecosystems.

Project ToDos

Before this is ready for general use, there’s still some work to do, among it:

  • Quality assured and continually maintained onboarding story into the frappe framework
  • A comprehensive development environment for Linux & MacOS (Windows on WSL2, only)
  • Fully supported deployment targets: VM, MicroVM, Host OS, OCI Container
  • Appropriate documentation at its layer of the stack with clear interlinking to upstream documentation

Regardless, I’m working on this in my freetime, hence it is a bootstrapped project. Please adjust your expectations, accordingly. And with that out of the way: I just wanted to gather early feedback from interested users.

Its predecessor has served me very well in production over the last year or so, so I guess it’s about time to spread the word just a little bit.

I’m always looking for interested parties willing to contribute!! After all, that’s the whole point of open sourcing it in the first place, right? So please feel free to do so — and above all: not overly intimidated by Nix :pray:


A tiny little update:

  • I’m in the process of porting our production deployment over to using upstream Frappix
  • In the process, we needed a better tool to pin inputs, based on nvchecker with a small patch
  • Today, a copy of our production database started running for the first time on a completely new pin of nixpkgs-23.11 which containes lots of new frappe dependencies that we had upstreamed over the last year or so
  • The amount of custom python packaging required has significantly molten down
  • Our puppeteering matrix chat integration also started working today again on a new version of the matrix server and after some refactoring on the side of its NixOS upstream module

So far so good. :rocket:

A couple of admirably audacious people in the Frappix chat room are already trying to run it for their own purposes :smile: . Hence, I’m trying to keep up with the docs as much as possible. But beware, for now, there are still dragons ahead.


I added a little script to answer the following question:

Which of my merged PRs already landed in a V15 release?

Hey @blaggacao great work here! This thread should be blowing up, but I suppose that the world of Nix is so massive and different this paradigm shift is a lot to take in, especially for those of us that have been developing Frappe apps almost exclusively on Ubuntu.

I’m especially interested in your OCI Container target, and curious how this may relate to the various paradigms that exist for containerizing Frappe.

I’ve also followed your PR for unix domain sockets support. This feature was long overdue, IMO (and I hope it gets merged soon!)

I’m super happy for the work you’re doing and excited to see how this will play out once these ideas gain more traction.


Thanks for the little encouragement! :smile:

I haven’t implemented it yet in Frappix (but I did in other projects), and I imagine something like:

  inherit (inputs) std;
  inherit (apps.pkgs) frappix;
in {
  web-entrypoint = std.lib.ops.mkOperable {
     package = frappix.frappe.pythonModule.buildEnv.override {extraLibs = [
       # other apps
     runtimeScript = ''
       # todo figure out the propper entrypoint script
  web = std.lib.ops.mkStandardOCI {
    name = "";
    operable = cell.web-entrypoint;
    meta.description = "My Frappe Project bundled OCI";
    config.Env = [
      # figure out which container-only environment to set
  # and so on for mariadb, redis (which are only pinned and proxied from upstream)
  # and then also different workers, scheduler, socketio

This then would be built with your respective bespoke package set from the apps.pkgs.frappix namespace, whether they are plain upstream or heavily patched.

If you have a stable base image (pre apps / pre frappe but post dependencies) then the CI should also run a couple of minutes faster, because GHCR is known to be faster than cache restore on Github, and definitely significantly faster than the current apt get install.
