Composable toolkit for clean, testable, and maintainable Python applications

ForgingBlocks

Composable abstractions and interfaces for writing clean, testable, and maintainable Python code.

---

Overview

Not a framework — a toolkit of composable contracts and abstractions.

ForgingBlocks helps you create codebases that are:

• Clean — with clear boundaries and intent
• Testable — by design, through explicit interfaces
• Maintainable — by isolating concerns and dependencies

It doesn’t dictate your architecture. Instead, it provides foundations and reusable abstractions for forging your own blocks.

Isolate external concerns from your core logic you will achieve systems that are adaptable and resilient. If you forge your own block you will achieve software with intent and clarity If you use blocks you will achieve consistency and reusability. ForgingBlocks helps you build systems that last.

You can use it to:

• Learn and apply architecture and design principles
• Build decoupled applications that scale safely
• Model systems with type safety and explicit intent
• Experiment with Clean, Hexagonal, DDD, or Message-Driven styles

Core Concepts

Foundations, not frameworks — ForgingBlocks provides the language for clean architecture.

This toolkit defines layer-agnostic foundations that compose into any design:

• Result, Ok, Err → explicit success/failure handling
• Port, InboundPort, OutboundPort → communication boundaries
• Entity, ValueObject, AggregateRoot → domain modeling
• Repository, UnitOfWork → persistence contracts
• Event, MessageBus, CommandHandler → messaging and orchestration

---

Installation

poetry add forging-blocks
# or
pip install forging-blocks
# or
uv add forging-blocks

Requires Python 3.14+

---

Quick Example

from forging_blocks.foundation import Result, Ok, Err

def divide(a: int, b: int) -> Result[int, str]:
    if b == 0:
        return Err("division by zero")
    return Ok(a // b)

result = divide(10, 2)
if result.is_ok:
    print(result.value)  # → 5

Setup

# Clone the repository
git clone https://github.com/forging-blocks-org/forging-blocks.git
cd forging-blocks

# Install dependencies
poetry install

# Run tests
poetry run poe test

# Run full CI suite
poetry run poe ci:check

Available Commands

# Testing - Primary Commands
poetry run poe test              # Run ALL tests (recommended)
poetry run poe test:unit         # Run unit tests only (fast feedback)
poetry run poe test:integration  # Run integration tests only
poetry run poe test:e2e          # Run end-to-end tests only

# Testing - Alternative Commands
poetry run poe test:debug        # Run tests with verbose output

# Code quality
poetry run poe lint              # Check code style
poetry run poe lint:fix          # Fix code style issues
poetry run poe type              # Type checking

# Release (maintainers)
poetry run poe release patch        # Test release (simulation)
poetry run poe release patch --execute  # Execute patch release

Test Architecture

This project uses a 3-tier testing architecture:

• Unit Tests (@pytest.mark.unit) - Fast, isolated tests with mocks or fakes
• Integration Tests (@pytest.mark.integration) - Real infrastructure in isolated environments
• End-to-End Tests (@pytest.mark.e2e) - Complete workflows (mostly skipped)

Quick feedback during development:

poetry run poe test:unit    # [FAST] Fast (~1s) - run frequently

Verify integrations before commits:

poetry run poe test         # [INFO] Complete test suite (~3s) - run before commits

See Testing Guide for detailed information.

Why It Matters

Most systems fail not because of missing features, but because of tight coupling, implicit dependencies, and unclear responsibilities.

ForgingBlocks helps you design code intentionally — so your system remains testable, extensible, and adaptable as it grows.

Contributing

Contributions are welcome!

1. Fork the repository
2. Install dependencies: poetry install
3. Create a feature branch: git checkout -b feature/your-feature
4. Make your changes
5. Run the full test suite: poetry run poe ci:check
6. Submit a pull request with a clear description

See CONTRIBUTING.md for detailed guidelines.

Release Process

For maintainers preparing releases:

# Prepare release (safe simulation)
poetry run poe release patch

# Execute release (creates branch and PR)
poetry run poe release patch --execute
