db/: contains migration file used by goose to handler db migration. It also contains the Dockerfile to build db container
order: contains the business logic of the three API services.
Database: postgres in container API: running locally
handler: responsible for parsing http requests and writing http response
usecase: preceded by handler, usecase has the business logic of creating, updating and querying orders. The dependencies are DBAdaptor and DistanceService which are used to store data and calculate distances.
pg_adaptor: is a thin layer above postgres db in which I use gorm library to simplify object manipulation.

- Due to time limitation, tests are not complete. Router, handler and business logic (
usecase) have good testing using mocks. But I don't have time to test the database adaptor. - It uses lock to prevent mutliple users taking the same order. This poses performance constraint to the service also doesn't scale very well.
- Only db is running in container. API should also be containerized once communication issues between containers is resolved
- No authentication
