William Carroll 44dca4a188 Move authorization logic into separate package
Relocated the logic for authorizing clients into a separate package that the
tokens server now depends on. Moving this helped me separate concerns. I removed
a few top-level variables and tried to write more pure versions of the
authorization functions to avoid leaking Monzo-specific details.

monzo_ynab

Exporting Monzo transactions to my YouNeedABudget.com (i.e. YNAB) account. YNAB unfortunately doesn't currently offer an Monzo integration. As a workaround and a practical excuse to learn Go, I decided to write one myself.

This job is going to run N times per 24 hours. Monzo offers webhooks for reacting to certain types of events. I don't expect I'll need realtime data for my YNAB integration. That may change, however, so it's worth noting.

Installation

Like many other packages in this repository, monzo_ynab is packaged using Nix. To install and use, you have two options:

You can install using nix-build and then run the resulting ./result/bin/monzo_ynab.

> nix-build . && ./result/bin/monzo_ynab

Or you can install using nix-env if you'd like to create the monzo_ynab symlink.

> nix-env -f ~/briefcase/monzo_ynab -i

Deployment

While this project is currently not deployed, my plan is to host it on Google Cloud and run it as a Cloud Run application. What I don't yet know is whether or not this is feasible or a good idea. One complication that I foresee is that the OAuth 2.0 login flow requires a web browser until the access token and refresh tokens are acquired. I'm unsure how to workaround this at the moment.

For more information about the general packaging and deployment strategies I'm currently using, refer to the deployments writeup.
