This is a reference application demonstrating an end-to-end Plaid integration, focused on linking items and fetching transaction data.

As a modern full-stack application, Pattern consists of multiple services handling different segments of the stack:

We use Docker Compose to orchestrate these services. As such, each individual service has its own Dockerfile, which Docker Compose reads when bringing up the services.

For more information about the individual services, see their readmes, linked in the list above.
