Mba Scraper

AWS Lambda code that scrapes schedule from MBA League website and returns .ics calendar with games.

Running Tests

just test

Code Style

The project uses Ruff for linting and formatting, all linters can be run with just:

just lint_full
just lint_full_ff  # (fast-fail mode)
just all  # (lint + tests)
just all_ff  # (lint + tests in fast-fail mode)

Building and Deployment

Building the Lambda Package

The project includes a build system that packages the application for AWS Lambda deployment:

just build

This command:

1. Clears the previous build directory (build/pkg)
2. Generates a frozen requirements file without dev dependencies
3. Installs all dependencies targeting x86_64-manylinux2014 platform (compatible with AWS Lambda)
4. Copies the lambda handler shim (lambda_function.py) to the package
5. Creates a timestamped zip file in the build/ directory (e.g., mba_scraper_20260201_005935.zip)

The resulting zip file contains:

• All Python dependencies
• The mba_scraper package with your application code
• A lambda_function.py shim that exposes the handler

Lambda Handler Shim

The project uses a shim file (lambda_function.py) at the root level to expose the Lambda handler:

This allows AWS Lambda to use the default handler configuration lambda_function.lambda_handler while keeping the actual implementation inside the mba_scraper package.

Package Structure:

build/pkg/
├── lambda_function.py          # Shim that exposes the handler
├── mba_scraper/
│   ├── __init__.py
│   ├── lambda_function.py      # Actual handler implementation
│   └── ...
├── aws_lambda_powertools/
└── ... (other dependencies)

Note: The shim file can be safely deleted if you update the AWS Lambda Runtime settings → Handler configuration to point directly to mba_scraper.lambda_function.lambda_handler.
