Real-Time Auction System Built with Clean Architecture, CQRS, ASP.NET, React & SignalR

Auction App is a full-stack, real-time auction platform demonstrating modern software architecture and development practices like Clean Architecture and CQRS patterns. It provides robust backend APIs via ASP.NET Core and React frontend (styled with Tailwind CSS).

Real-time bidding is powered by SignalR (using WebSockets).

• Clean Architecture + CQRS

  Maintainable codebase with clear separation of concerns and optimized command/query handling.

• Real-Time Bidding

  Seamless real-time communication using SignalR backed by WebSockets for instant updates.

• Modularity

  Using practices of CLean Architecture was achieved high level of modularity of the project. Each next layer depends only on the previous and not vice-versa.

Basically, repository already includes generated API for front-end client, but if you want to generate it once more, just place swagger.json in AuctionApp.React directory and use generateApi.sh script in the same folder.
