What this system is

Features

Added Docker Compose configuration for local and production environments

The project now includes a complete Docker Compose setup to containerize the ChitChat WebAPI and a MySQL 8.0.39 database. This enables local development with hot-reload and secret mounting, while providing a production profile that maps ports 80/443, enforces a 'unless-stopped' restart policy, and loads environment variables from a .env file. A .dockerignore file is also added to exclude unnecessary files from the build context.

docker · high confidence

The application now includes Entity Framework Core configuration classes for a wide range of domain entities, enabling the database schema to be generated and managed for the social platform. New mappings have been added for Post, Comment, Reaction (on posts and comments), and PostMedia. The system also defines relationships for User profiles, Follower requests, and User interactions. Additionally, the configuration layer now supports Chat and Notification features, with specific mappings for Conversation, Message, and various notification types (Comment, Post, and User notifications).

Initial WebAPI project scaffolding and configuration

The ChitChat.WebAPI project has been initialized with a complete ASP.NET Core WebAPI setup. This includes dependency injection for JWT authentication and Swagger/OpenAPI, configuration for development and production environments (including HTTPS endpoints and database connection strings), and a Dockerfile for containerized deployment.

Initial database schema and seeding for the ChitChat application

The application now includes the core Entity Framework Core configuration and database seeding logic. The \ApplicationDbContext\ defines the data model, including entities for users, posts, comments, reactions, conversations, and notifications. Additionally, the \AutomatedMigration\ class ensures the database schema is updated on startup, while \DbContextSeed\ populates the database with default roles and admin user accounts.

Initial infrastructure setup for authentication, caching, and real-time communication

The ChitChat.Infrastructure module has been initialized with core backend capabilities. This includes JWT-based authentication and authorization registration, a memory caching service, and a global exception handler middleware that maps application errors to appropriate HTTP status codes. Additionally, the infrastructure layer now supports real-time communication via SignalR hubs for conversations and user notifications, alongside configuration for Cloudinary file storage and Entity Framework Core database interactions.

Initial project scaffolding and documentation

The repository is initialized with a .NET Core solution structure organized into Clean Architecture layers (Domain, Application, Infrastructure, WebAPI, and DataAccess). A .editorconfig file is added to enforce C\# coding standards and formatting rules. The .gitignore file is updated to exclude environment variables (.env) and IDE settings. The README.md is expanded to document the backend services, tech stack, and installation steps for the Chit Chat social network application.

Introduce Clean Architecture application layer with service and mapping infrastructure

The ChitChat.Application project now establishes the core application layer, introducing a comprehensive set of services for managing users, posts, conversations, notifications, and follow relationships. This includes the implementation of a machine learning-based post recommendation service using Microsoft ML, alongside standard CRUD services for chat, comments, and user profiles. The change also adds the necessary DTOs, AutoMapper profiles for object mapping, and dependency injection registration to support these new capabilities.

Introduce data access layer with dependency injection and configuration

The ChitChat.DataAccess module now includes core infrastructure to support the application's data operations. A new DatabaseConfiguration class provides a container for the connection string, while DependenceInjection registers the repository pattern implementations (including user, conversation, and interaction repositories) via the standard Microsoft.Extensions.DependencyInjection framework. Additionally, global using directives are added to streamline common System and Entity Framework Core namespaces across the project.

src/ChitChat.DataAccess · high confidence

Added new API controllers to expose endpoints for user registration, login, logout, and token refresh, as well as full CRUD operations for posts, comments, and replies. The update also introduces controllers for managing user profiles, following/unfollowing other users, and retrieving recommended users. Additionally, the API now supports conversation management, including creating and deleting conversations, sending and updating messages, and retrieving conversation lists. A notification controller has been added to retrieve user notifications, and a placeholder controller for machine learning model training is included.

Architecture

Introduce generic repository pattern with specific implementations for conversations, users, and interactions

The data access layer now uses a generic BaseRepository pattern to standardize common CRUD operations (Get, Add, Update, Delete) across entity types. Specific repositories (Conversation, User, UserFollower, UserInteraction) implement this pattern or provide custom queries, enabling a consistent data access API for features like messaging, user recommendations, and interaction tracking.

Behavioural changes

Database schema updates for comments, posts, and notifications

The database schema has been updated to support new and modified features. A new 'V1Update' migration adds 'CommentCount' and 'ReactionCount' integer columns to the 'Posts' table, and adds 'CommentType' and 'ReactionCount' integer columns to the 'Comments' table, while removing temporary test columns. The 'Comments' table's 'CommentType' column is later changed from an integer to a string type. Additionally, a 'ChangeNotification' migration introduces separate tables for 'CommentNotifications', 'PostNotifications', and 'UserNotifications', replacing a generic 'Notifications' table, and adds a 'MediaAvatarType' column to 'AspNetUsers'.

Test coverage

Added initial test project structure

Added a new test project containing a placeholder Class1, establishing the foundation for future test coverage in the ChitChat application.

This is the PUBLIC form of this artifact. Findings are listed in full, but the details of SECURITY findings — which rule fired, in which file, on which line, and how to fix it — are deliberately withheld, and any secret-scanner results are excluded entirely. Where detail is absent here it was REMOVED FOR PUBLICATION; it is not missing from the analysis. The complete artifact is available from the repository owner.

Inconsistent spelling of 'Framework'. The method 'AddEntityFramewordCore' uses 'Frameword' (typo), while the type 'CloudinaryRegisteration' (though also misspelled for Registration) implies a configuration/registration context. More importantly, 'Frameword' is a clear typo for 'Framework'.
Inconsistent spelling of the word 'Registration'. Some symbols use 'Registeration' (missing 'i'), while others use the correct 'Registration'. Specifically, 'EntityFrameworkRegisteration' and 'CloudinaryRegisteration' are misspelled, whereas 'SignalRRegistration' is correct.
