fast ledger

A quick implementation of the ledger and entities aspects of a bank. There are no rules stopping negative balances, duplicate accounts etc. There is no security.

why python?

I briefly got to use fastapi a while back and saw pydantic was quite a breath of fresh air in terms of declaring models in python (see ledger_models).

core libraries

• pydantic

• pytest

• pydantic factories (really awesome library like factory girl but easier)

running

pip install -r requirements.txt pytest

next steps

• More tests, a ledger should have 100% test coverage, run coverage report for more info -- But mainly some methods in transactions and assets are missing tests
• Implement a scheduler to run update balances
• Implement reports
• Implement a quick frontend (for fun)
• Entity resolution service to prevent duplicates
