Simple Bank Accounts System

Implementation of a simple bank account management system using akka.io.

The purpose of this repository is to be familiarized with the new akka-typed API.

How to read the code

The code is split and organized to several branches in order to reflect the progression of the implementation. The domain is intentionally left extremely simple in order to display as many akka features as possible.

The implementation progress is as following:

Part 1 - A simple actor with tests

• Part 1.1 Create a simple AccountHolder actor.

• Part 1.2 Use akka ask pattern to interact with the AccountHolder from outside the system.

• Part 1.3 Create AccountHolderSpec tests.

Part 2 - Create a supervisor cache group actor

• Part 2.1 Create an AccountGroup in memory cache and supervisor actor.

• Part 2.2 Create AccountGroupSpec tests.

Part 2 - Implement an REST API using akka-http

• Part 3.1 Create an application MainSupervisor actor. Create an HttpServer server actor with account endpoints.

• Part 3.2 Implement HttpServer endpoints and integrate the existing account actors.

• Part 3.3 Simulate some account operations traffic. Create a transaction-client project that uses akka-stream API to post continuously random requests to the backend.
