Installation

Kajson requires Python 3.10 or higher and can be installed using your favorite package manager.

Requirements

  • Python ≥ 3.10
  • Pydantic v2 (installed automatically)

Installation Methods

Using pip

pip install kajson

Using poetry

poetry add kajson

uv pip install kajson

Development Installation

If you want to contribute to Kajson or install from source:

# Clone the repository
git clone https://github.com/Pipelex/kajson.git
cd kajson

# Install with development dependencies
make install

The development interpreter is the Python version that .python-version names at the repository root, and make install builds .venv on it. If .venv was built on another Python, the next make install rebuilds it on the pinned version. To try another version, run PYTHON_VERSION=3.13 make install with the version you want; a plain make install afterwards returns .venv to the pin. CI runs the checks and tests on every Python version kajson supports.

Verify Installation

After installation, you can verify that Kajson is properly installed:

import kajson

# Check version
print(kajson.__version__)

# Test basic functionality
data = {"message": "Hello, Kajson!"}
json_str = kajson.dumps(data)
print(json_str)
