meysamhadeli/booking-monolith

This system is a .NET 10 monolithic booking service that manages flight, aircraft, and seat data alongside the creation and management of bookings. It employs a CQRS architecture with separate read models in MongoDB and write models in PostgreSQL, synchronized via an event-driven pipeline using EventStoreDB and MassTransit. The platform provides a minimal API layer secured by JWT authentication and supports local development orchestration through .NET Aspire.

The API service is initialized with a new infrastructure layer that integrates with .NET Aspire for local development orchestration. This includes a centralized \SharedInfrastructureExtensions\ class that configures the application with JWT authentication, IdentityServer, MediatR with validation and logging behaviors, MassTransit for in-memory messaging, and multiple data stores (PostgreSQL, MongoDB, EventStoreDB). The service also enables distributed observability (OpenTelemetry, Prometheus) and resilience patterns via Aspire's service defaults, while \Program.cs\ wires these components together to expose minimal endpoints.

src/Api · high confidence

This change introduces the initial structure for the Booking Monolith, establishing the foundational domain models and infrastructure for the Flight and Booking aggregates. It defines the core entities (Booking, Aircraft, Airport, Flight, Seat) with value objects and validation logic, sets up the read/write data access layers using Entity Framework Core (PostgreSQL) and MongoDB, and implements event mapping and projection logic to synchronize domain events to the read models.

src/BookingMonolith · high confidence

This change introduces the initial implementation of core Flight and Booking capabilities, including endpoints and handlers for creating, updating, deleting, and querying flights, aircraft, airports, and seats. It also adds the CreateBooking feature, which orchestrates flight and seat availability checks to finalize a booking. The implementation follows a CQRS pattern with separate read models (MongoDB) and write models (SQL/Entity Framework), and includes internal commands to synchronize the read side.

This change adds the core architectural components for the application within the BuildingBlocks library. It introduces a CQRS foundation with MediatR pipeline behaviors for caching and cache invalidation, alongside interfaces for commands and queries. An event-driven architecture is established with domain, integration, and internal event types, a composite event mapper, and an event dispatcher that handles publishing and persistence. Persistence support includes an EF Core base context with automatic audit tracking, optimistic concurrency, soft deletes, and transaction management, as well as an EventStoreDB integration for event-sourced aggregates, subscriptions, and projections. Utility features like pagination with Sieve and database seeding are also included.

src/BuildingBlocks · high confidence

The repository has been initialized with a new solution structure targeting .NET 10 (SDK 10.0.103), replacing the previous .NET 9 baseline. This includes a global \Directory.Build.props\ file that enforces modern C\# coding standards, nullable reference types, and a suite of Roslyn-based analyzers. The solution now includes dedicated Aspire projects (\AppHost\ and \ServiceDefaults\) to support service discovery and local orchestration, alongside standard development tooling such as \.editorconfig\, \.dockerignore\, and commitlint configuration.

(repo-wide) · high confidence

The repository now enforces commit message standards and code formatting automatically. A new commit-msg hook runs commitlint to validate commit messages against configured rules, while a pre-commit hook executes npm scripts for formatting and CI-format checks before changes are staged.

.husky · high confidence

The project is initialized as a .NET 10 monolith, with core libraries and the API service targeting net10.0 and referencing Microsoft .NET 10 packages (e.g., EF Core 10.0.3, ASP.NET Core 10.0.3). An Aspire AppHost is added to manage infrastructure, referencing Aspire.Hosting packages at version 13.1.1 (including Docker, MongoDB, PostgreSQL, RabbitMQ, Redis, EventStore, and Elasticsearch hosts). The build is configured with commitlint and Husky for conventional commits, and integration tests are set up with xUnit and Microsoft.NET.Test.Sdk.

(dependencies) · high confidence

A new architectural diagram (booking-monolith.drawio) has been added to the assets folder, illustrating the system's structure. The diagram depicts a monolith containing Identity, Flight, Passenger, and Booking domains, supported by Postgres, EventStore, and Mongo databases, and an Outbox Processor.
