Trading Chart Service

Note on the solution

• The solution follows the popular clean code structure where the handler package is the equivalent of the controller layer. All external structures such as requests and events are converted to internal models to work with in the service and repository layers. This structure promotes modularity, testability, and extensibility.
• Due to time constraint, authentication, error handling, logging, and comprehensive testing are not fully implemented or implemented at a very basic level.

How to run the service

• Start GRPC server:

  make run-server-docker

• Start websocket listener:

  make run-ws-listener-docker

Room for improvement

• Tests need to be added
• Error handling could be improved
• Could use a query builder library for DB queries
