Scratch Notes

Ideas and Notes

• Feature Enhancement: Consider adding a caching layer to the Trade API to improve response times for frequently accessed data.
• Refactoring: Evaluate the current architecture for the Portfolio Management module to simplify dependencies and improve testability.

Commands and Shortcuts

• Docker Commands:

  • Start PostgreSQL:

    docker run -e POSTGRES_PASSWORD=mysecretpassword -p 5432:5432 postgres

  • Start RabbitMQ:

    docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

• .NET Commands:

  • Run a specific microservice:

    dotnet run --project ./TradeService/TradeService.csproj

  • Run all unit tests:

    dotnet test

Migration Command

• Tools > Nuget Package Manager > Package Manager Console > Default Project: Data
• Add-Migration Example
• Update-Database
• Remove-Migration
• Script-Migration
• Drop-Database

Init Oracle Database

• CREATE USER luyenhaidangit IDENTIFIED BY haidang106;
• GRANT DBA TO luyenhaidangit;

Temporary Design Notes

• Authentication Flow:

  • Implement OAuth2 for enhanced security in user authentication.
  • Add rate limiting to login endpoints to prevent brute-force attacks.

• Potential Tech Debt:

  • Remove hard-coded API URLs from the codebase. Instead, move them to the configuration files or environment variables.

Miscellaneous

• Pending Research:
  • Evaluate the use of MassTransit versus NServiceBus for message brokering.
  • Investigate best practices for implementing retries in RabbitMQ consumers to handle intermittent failures.

Useful Links

• Official .NET 8 Documentation
• Docker Best Practices
• MassTransit Documentation
