Pre-release

This release is a pre-release and may not be stable for production use.

Tiferet – Domain-Driven Design, beautifully balanced

Tiferet is a Python framework that brings Domain-Driven Design into focus with elegance and clarity.

Inspired by the Kabbalistic principle of harmony and beauty in balance, Tiferet helps you turn complex business logic into maintainable, configuration-driven applications — where purpose, structure, and execution feel naturally aligned.

At a glance

Blueprints-first app entry point via build_app (exported as App)
Domain events as the core unit of behavior
YAML for features, workflows, dependency injection, errors, CLI commands
Clean layering: domain objects • aggregates • transfer objects • services
Structured, multilingual errors built-in
Easy to extend to CLI, web, scripts, TUI, … Current status: 2.0.0 (stable release)

Quick Start – Add two numbers in ~3 minutes

# 1. Set up environment
python3 -m venv tiferet-demo && source tiferet-demo/bin/activate
pip install tiferet

Create these files in your project folder:

demo.py

from tiferet import App
app = App(
    'basic_calc',
    app_config='config.yml',
)                               # App is the build_app alias

result = app.run(
    feature_id='calc.add',
    data={'a': 19, 'b': 23},
)

print(f"19 + 23 = {result}")    # → 42

config.yml

interfaces:
  basic_calc:
    name: Basic Calculator
    description: Basic calculator interface

services:
  add_number_event:
    module_path: app.events.calc
    class_name: AddNumber

features:
  calc:
    add:
      name: Add Numbers
      commands:
        - service_id: add_number_event

app/events/calc.py
(the domain event itself – very minimal)

from tiferet.events import DomainEvent

class AddNumber(DomainEvent):
    def execute(self, a: int, b: int, **kwargs) -> int:
        return a + b

Run:

python demo.py

You should see:

19 + 23 = 42

Why Tiferet?

Configuration as code — features, DI, errors, CLI all live in YAML
Domain logic stays pure — focused events & aggregates
Infrastructure is injectable — file/db/utils behind clean service contracts
Built for evolution — today CLI, tomorrow FastAPI or TUI
Strong testability — events are easy to invoke in isolation
