SwiftLift

"Swift" and "Lift" imply quick and efficient transportation, indicating a commitment to providing timely and reliable rides.

System Description

Creating a simplified Uber-like system as a case study to apply what I've learned over the years and what I'm about to learn.

First do it, then do it right, then do it better

Goals

• Recreate a distributed system.
• Implement Event-Driven Microservices Architecture.
• Apply Domain-Driven Design (DDD).
• Use Command Query Responsibility Segregation (CQRS).
• Utilize gRPC for synchronous communication.
• Implement Request-Response Pattern.
• Apply API versioning.
• Use API Gateway / YARP.
• Use InMemory / Service Bus.
• Implement Inbox / Outbox Pattern.
• Use Saga Pattern.
• Implement Circuit Breaker Pattern.
• Ensure Resiliency and Fault Tolerance.
• Implement Central Configuration Management.
• Design Idempotent Event Consumers.
• Handle Eventual Consistency.
• Use both Relational and Non-Relational Databases.
• Enforce Early Validation with Options Settings.
• Secure Endpoints Based on JWT from Multiple Identity Providers.
• Use Quartz for Scheduled Tasks in Background Services.
• Implement Service Discovery.

Architectural / Design / Implementation Considerations

• Use Aspire as a Startup Project Template.

• Add .editorconfig Using the Aspire as a Starting Point.

• Use Dotnet Tools Locally.

• Manage NuGet Package Versions Centrally.

• Propagate Correlation ID Across Applications.

• Integrate with Application Insight.

  • Enable Azure Monitor.
  • Add Connection String Environment Checker.

• Use Feature Flags to Manage Both Functional and Technical Requirements.

• Add Snake JSON Serializer / Deserializer Abstractions.

  • And Their Implementations Based on System.Text.Json.

• Consider these popular libraries as part of the solution:

  • Hashids.net / sqids-dotnet.
  • EF Core.
  • SignalR.
  • FastEndpoints.
  • Masstrasit.
  • Wolverine as Mediator or MediatR.
  • SimpleInjector DI.
  • Mapster.
  • Marten as Transactional Document DB and Event Store.
  • FluentResults.Extensions.AspNetCore.
  • StronglyTypedId.
  • Refit.
  • Polly.
  • Lazard as Local Services Bus.
  • HeaderPropagation.

• For Testing:

  • NetArchTest.EnhancedEdition for Architecture Conventions.
  • Microsoft.AspNetCore.Mvc.Testing for Integration Testing.
  • AutoBogus.Conventions for Fake Data Generation.
  • FluentAssertions for Assertion Evaluation.
  • NSubstitute for Mocking.
  • xUnit as Tests Runner.
  • Coverlet and ReportGenerator Tool for Code Coverage and Reporting.
  • TestContainer.

VS2022 IDE Extensions

• Fine Code Coverage.
• Code Clean Up on Save.
• Github Copilot.
