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 asApp) - 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: 2.0.0b3 (pre-release – actively evolving toward stable v2)
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_yaml_file='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
