Node.js application that syncs Splitwise shared expenses to YNAB accounts.
The app runs as a cron job every x minutes, and retrieves expenses on a Splitwise group and parses the expense info in order to be provided to YNAB API. Transactions show up on YNAB as uncleared, uncategorized and unapproved in order to be manually processed and categorized as a second step.
When you have a new expense on splitwise where you owe money (who you are is based on the user id provided), it will be introduced as an outflow. If you are owed, then it's treated as an inflow.
for local run: npm run local
for Heroku deployment, set up node.js worker and run: npm run deploy
- Missing tests
- Only processes expenses that occur after app startup
- Keep app state on database (currently ids of processed expenses are stored in-memory)
- Docker support
- Error handling
