MiniTrello

MiniTrello is a side project meant to simulate a simple behavior for the famous software project management app Trello using Event Sourcing pattern. Currently MiniTrello implements in-memory event store.

MiniTrello:

• Follows Domain-Driven-Design principles
• Implements Event Sourcing architectural pattern
• Follows the Clean-Architecture
• Implements various design patterns and best practices including:
  • Writing unit tests
  • Writing architectural tests
  • Api Versioning
  • Structured Logging

MiniTrello's behavior:

MiniTrello currently has 2 aggregates: Ticket and Comment, each ticket can have comments and any action to them is recorded as a new event.

As stated in the diagram; once the ticket is created we can:

• Assign it to a valid user
• Unassign it
• Perform various actions to update its status:
  • ToDo -> InProgress
  • InProgress -> CodeReview
  • CodeReview -> Test
  • Test -> InProgress | Done

For Comments, there are three actions we can do for now:

• Create a comment
• Modify the comment content
• Delete a comment
