mehdihadeli/vertical-slice-api-template

This is a .NET 9-based application template that implements a product catalog service using a CQRS architecture with MediatR. It provides full CRUD operations for products, including creation, retrieval, and paginated listing, backed by a PostgreSQL database with Entity Framework Core. The system integrates with external APIs via auto-generated Kiota and NSwag clients, and includes comprehensive unit, integration, and end-to-end test coverage.

A new API client implementation using the Kiota SDK has been added to the \src/ApiClients/Vertical.Slice.Template.KiotaClients\ directory. This includes the \CatalogsKiotaApiClient\ entry point, request builders for the \/api/v1/products\ and \/api/v1/products/{id}\ endpoints, and the corresponding model classes (\CreateProductRequest\, \CreateProductResponse\, \GetProductByIdResponse\, etc.). This provides an alternative, auto-generated client for interacting with the Catalogs service alongside the existing NSwag-based client.

The template now includes the complete implementation for creating, retrieving by ID, and paginated listing of products. This adds the CQRS commands, handlers, and validators for creating a product, as well as the query handlers and endpoints for fetching a single product and listing products with pagination support.

The Catalogs module now includes a database migration that creates the 'products' table in the 'catalog' schema, along with a data seeder and a design-time factory to support database setup and testing. This change introduces the foundational data layer for the catalog feature, including the initial migration script and the infrastructure to apply it.

The .devcontainer directory now contains a complete development environment setup, including a Dockerfile, devcontainer.json, and supporting scripts. The configuration installs .NET 9.0.101 SDK and runtime, along with GitHub CLI, PowerShell, Node.js, and various VS Code extensions and settings tailored for C\# and .NET development. It also includes scripts to install the Meslo Nerd Font for improved terminal rendering.

The Products area now includes a complete set of scaffolding files: a Product entity, a read model, DTOs, and a mapper class that uses Mapperly to convert between domain models, DTOs, and request/response types. Additionally, EF Core configuration and Sieve read-model configuration are added, and the module is wired into the application's routing and service registration.

The Vertical.Slice.Template.Api project has been restructured with new configuration files (appsettings.json, appsettings.test.json, launchSettings.json) and a Program.cs entry point that configures Serilog logging, dependency injection validation, and infrastructure services. The project now includes VS Code launch and task configurations for debugging and Docker builds, along with metadata classes for catalogs. The solution file and various configuration files have been added to support the template's API layer.

The shared abstraction layer now includes a comprehensive caching system with interfaces for cache queries, requests, and services, alongside pipeline behaviors for caching and cache invalidation. Additionally, new interfaces are introduced for CQRS commands and queries, domain events, and messaging, providing a structured foundation for these architectural patterns.

The application's startup configuration is now consolidated into dedicated extension methods within the \WebApplicationBuilderExtensions\ and \WebApplicationExtensions\ classes. This change introduces a structured approach to registering services, including typed HTTP clients for REST, Connected Service, and Kiota-based APIs, alongside infrastructure services like MassTransit, caching, rate limiting, and health checks. The pipeline is also updated to use the \Mediator\ source generator for message handling instead of MediatR, and the application now supports both in-memory and PostgreSQL database contexts based on configuration.

The project now enforces commit message standards via commitlint and applies automated formatting and style checks before each commit. Specifically, the .husky directory now includes a commit-msg hook that runs commitlint to validate messages, and a pre-commit hook that executes npm scripts for fixing analyzers, style, C\# formatting, and general formatting and style checks.

The legacy implementations for creating and retrieving products have been removed from the application. Specifically, the \CreateProduct\ and \GetProductById\ features, along with their associated HTTP endpoints and handlers, have been deleted. This eliminates the ability to create new products via the \api/products\ POST endpoint and fetch product details via the \api/products/{id}\ GET endpoint.

The project now requires .NET SDK 9.0.101 or later, as specified in the global.json file. This update aligns the development environment with the latest .NET 9 features and ensures compatibility with the template's dependencies and tooling.

(repo-wide) · high confidence

Added end-to-end tests for the GetProductById feature; Added integration test for creating a product; Added integration tests for connected service clients and API contracts; Added unit tests for GetProductByPage; Added unit tests for product creation flow.

The project has been upgraded to .NET 9, with all .NET and third-party package versions centralized in \Directory.Packages.props\ and \tests/Directory.Packages.props\. This includes updates to Microsoft.AspNetCore, Entity Framework Core, MassTransit, and OpenTelemetry packages. The template also introduces new client generation tools (NSwag and Kiota) and modernizes the build system with a \package.json\ for Node.js tooling and a \package-lock.json\ for lockfile consistency.
