What this system is

This release introduces the core microservices architecture, featuring new implementations for the auction, bidding, and request services, each with dedicated HTTP APIs, database repositories, and Kafka-based event publishing. The frontend application is launched with a complete React-based UI, including role-based access control and a centralized service layer for all backend interactions. Under the hood, the platform upgrades to Go 1.20.2, standardizes build infrastructure with shared Docker templates, and shifts user authentication from sessions to JWT-based security. The release also establishes a robust integration test suite and seeds the demo environment with realistic data for immediate validation.

Features

Add frontend service layer for auctions, bids, requests, and authentication

The frontend now includes a new services layer that encapsulates all HTTP interactions with the backend. This includes dedicated modules for managing auctions (listing, status updates, winner assignment, rejection, and deadline extension), bids (creation and retrieval), requests (creation, approval, and rejection), and user authentication (login, logout, and user details). This refactors the frontend to use a centralized API client for all data fetching and mutations.

Added TypeScript type definitions for Auction, Bid, Request, and User models

New TypeScript interfaces have been introduced in the frontend client to strongly type the core domain models. The \auction.ts\ file defines \Auction\, \ExtendedAuction\, \FormattedAuction\, and \ExtendedFormattedAuction\ interfaces, capturing fields such as title, creator, deadline, status, and winning bid details. The \bid.ts\ file adds \Bid\ and \NewBid\ interfaces to represent bid data and submission payloads. The \request.ts\ file introduces \Request\ and \NewRequest\ interfaces for handling request data. Finally, the \user.ts\ file defines \User\ and \UserDetails\ interfaces, including fields for username, email, phone, and roles. These changes provide type safety and autocompletion for these entities across the frontend application.

Auction service configuration and entry point

The auction service now includes its application entry point and a structured configuration system. The main.go file initializes the application using a new config package that loads settings from config.yaml and environment variables. The config package defines structures for app metadata, HTTP server settings (including session and auth secrets), logging levels, PostgreSQL connection details, and Kafka broker URLs, allowing the service to be configured via environment variables or YAML files.

Auction service now handles bid and request events via new controllers

The auction-service has added new event handlers for 'bid-created' and 'request-approved' messages. When a bid is created, the new BidController processes the message and calls the bid service. When a request is approved, the new RequestController creates a corresponding auction with the request's details and the message timestamp as the deadline. This implements the backend routing for these two event types.

Bidding service application entry point and dependency wiring

The bidding service's main application entry point (app.go) was added, establishing the HTTP server, database connections, Kafka messaging, and service layer wiring. This change introduces the core application structure for the bidding service, including repository initialization for auctions and bids, authentication service setup, and HTTP route registration.

Demo application now seeds realistic user, request, and auction data

The demo application now includes a complete set of seed data and orchestration logic to populate the system with test users (SuperAdmin, Residents, Bidders), service requests, and auction states. This allows users to run the demo to see a fully populated state with multiple users and auction scenarios, rather than an empty or minimal initial state.

HTTP routing and middleware configuration for the bidding service

The bidding service now exposes its HTTP endpoints through a centralized router that configures standard middleware (recovery, CORS, JWT authentication) and registers routes for bid operations. Specifically, the router defines endpoints for creating a bid, retrieving a bid by ID, fetching bids by auction ID, and counting or listing the authenticated user's own bids, alongside a health check probe.

services/bidding-service/internal/routes/http · high confidence

Initial database schema and seed data for user service

The user-service now includes its first two database migrations. The schema creates a 'users' table containing fields for username, email, phone, and password hash, along with a roles array. Additionally, the second migration seeds the database with an admin user and several resident and bidder test accounts.

services/user-service/migrations · high confidence

Initial database schema migrations for auction and bidding services

Added the initial database migration scripts for both the auction and bidding services. The auction service now includes SQL to create the 'auctions' and 'bids' tables, while the bidding service includes corresponding migration files to manage the same schema structure. These changes establish the foundational data models required for both services to operate.

Introduce Nginx-based API gateway with CORS and JWT authentication

The api-gateway now includes Nginx configuration files that route requests to backend services (user, request, auction, and bidding). The gateway enforces Cross-Origin Resource Sharing (CORS) headers for preflight and standard requests, and implements an internal authentication flow where the /request/ and /auction/ endpoints require a valid JWT header (X-Internal-Jwt) obtained via an /auth/ proxy. This establishes the entry point for client requests, handling both public and authenticated routes.

Introduce PostgreSQL repository for auction service

The auction service now uses a new PostgreSQL repository implementation to manage auction data. This adds database persistence for core auction operations, including creating auctions, retrieving lists with pagination, finding auctions by creator or ID, and updating auction status and winning bid details. The repository supports querying auctions by status and managing open auctions past their deadline, enabling the service to store and retrieve auction information from the database rather than relying on in-memory or other storage mechanisms.

Introduce bid and auction service layers with event publishing

The bidding service now includes dedicated service layers for managing bids and auctions. The new \BidService\ exposes methods to create a bid, retrieve a single bid by ID, fetch all bids for a specific auction, and list or count bids for a specific user. The \AuctionService\ provides operations to create and update auctions, as well as check if an auction is open for bidding. Additionally, the \BidEvents\ component publishes a \bid-created\ message to the messaging system whenever a new bid is created, enabling downstream services to react to bid events.

services/bidding-service/internal/service · high confidence

Introduce configuration management for the bidding service

The bidding service now uses a structured configuration system to manage application settings. This includes environment variables and YAML files for HTTP ports, database connections (PostgreSQL), Kafka endpoints, and logging levels. The service entry point has been updated to load this configuration at startup, ensuring that all components receive their required settings.

services/bidding-service/config · high confidence

Introduce new frontend components for auction and request management

The frontend now includes a suite of new React components to support the auction and request workflows. Users can now view and manage their service requests, bids, and rejected requests via the Home dashboard. Administrators and assigned users can manage auctions through the AdminBoard, which provides access to Pending, Assigned, In Progress, and Closed auction lists. New components allow users to create bids, view their bid history, and update auction statuses, while a reusable Footer and ProfileImageBadge component have been added to the UI.

clients/frontend/src/components · high confidence

Introduce request-service with HTTP endpoints and database schema

The request-service is introduced as a new microservice, providing HTTP endpoints for creating, rejecting, approving, and querying requests by status and user. The service includes a PostgreSQL schema for the requests table and a repository layer that supports filtering, pagination, and counting of requests. The service also publishes a 'request-approved' event to Kafka upon approval.

services/request-service · high confidence

Introduces shared domain models and authentication infrastructure

The \pkg\ directory now contains a new \auth\ package that provides JWT-based authentication and role-based endpoint authorization, alongside entity models for Auctions, Bids, Requests, and Users. Additionally, the directory includes a \messaging\ package implementing a Kafka publisher and subscriber for inter-service communication, as well as utility packages for pagination and array operations.

pkg · high confidence

Launch of auction-service HTTP API

The auction-service now exposes a new HTTP API for managing auctions and bids. Users can retrieve auction lists, counts, and status-based queries, as well as manage their own auctions. Administrators can extend auction deadlines, update winners, and change auction statuses. The service also includes health check and JWT authentication middleware.

New HTTP controller for bid management endpoints

Added a new HTTP controller in the bidding service that exposes endpoints to create a bid, retrieve a bid by ID, fetch all bids for a specific auction, and list/count the current user's own bids. The create endpoint validates that the associated auction is open to receive bids before allowing submission.

services/bidding-service/internal/routes/http/bid · high confidence

New event controllers for auction and request processing

The bidding service now exposes dedicated event handlers for processing incoming messages. A new \AuctionController\ handles \Create\ and \Update\ operations for auctions, while a \RequestController\ processes new requests by converting them into open auctions with a timestamped deadline. Both controllers validate message payloads and delegate to the underlying service layer.

services/bidding-service/internal/routes/events/request · high confidence

New events client for handling request and auction updates

A new events client has been introduced in the bidding service to subscribe to message queue topics for 'request-approved' and 'auction-updated' events. This client initializes controllers to process incoming messages, specifically triggering the creation of new requests and updating auction states as those events arrive.

services/bidding-service/internal/routes/events · high confidence

Request service application entry point and startup logic

The request service now includes a central application entry point that initializes the HTTP server, database connection, message publisher, and service dependencies, then manages graceful shutdown on interrupt signals.

Behavioural changes

Auction service exposes HTTP endpoints for managing auctions and bids

The auction service now provides a full set of HTTP handlers and service logic for managing auctions. Users can now retrieve all auctions, count them, and filter by status or creator. A new endpoint allows updating an auction's winner by identifying the lowest bid and the second-lowest bid (Vickrey-style logic), updating the auction status to 'Assigned' and recording the winner and winning amount. Additionally, users can update auction statuses, retrieve auctions that have passed their deadline, and extend auction deadlines. The bid service supports finding winning and second-winning bids, enabling the resolution of auctions.

Initialize multiple databases and run migrations for new services

The local development environment now supports multiple PostgreSQL databases. A new Dockerfile and initialization script allow the Postgres container to automatically create and grant privileges for multiple databases (e.g., auction, bidding, request) based on the POSTGRES\_MULTIPLE\_DATABASES environment variable. Additionally, the init script has been updated to run database migrations for user-service, auction-service, bidding-service, and request-service, ensuring all service schemas are applied on startup.

Removed legacy user entity and session-based authentication middleware

The user-service has removed the 'User' entity struct and the session-based 'AuthRequired' middleware. This eliminates the previous session-cookie authentication mechanism in favor of a new JWT-based approach, as indicated by the removal of the old authentication and entity code.

user-service/internal · medium confidence

Removed user database migration files

The database migration files for the 'user' table have been removed from the user-service. This includes the SQL scripts that previously created the 'users' table (containing id, username, passwordHash, and a unique constraint on username) and its corresponding down migration. This change affects the database schema management for the user service.

user-service/migrations · high confidence

Upgrade Go runtime and standardize service build infrastructure

The Go runtime used for building services has been upgraded from version 1.17.1 to 1.20.2, improving the underlying execution environment for all microservices. Additionally, the build infrastructure has been standardized: the previous service-specific Dockerfiles have been replaced by a shared \Dockerfile.service\ template that dynamically copies each service's code and dependencies, simplifying the build process across the platform.

(repo-wide) · high confidence

User service now supports email, phone, and role-based authentication

The user service has been updated to include email and phone number fields in the user model and database schema, allowing these attributes to be stored and retrieved. Additionally, the service now supports role-based authentication by generating JWT tokens containing user roles and public user information, and exposes new endpoints to retrieve user details and authenticate users with these enhanced claims.

services/user-service/internal · high confidence

Test coverage

Add integration test suite for microservices; Added test data fixtures for integration tests; Removed user-service integration test suite.

Dependencies

Added frontend client dependencies and Go workspace configuration

The frontend client now includes a full set of React, testing, and utility dependencies (including React 18, React Router 6, and Formik), alongside a generated yarn.lock file. Additionally, a Go workspace file (go.work) was added to manage the multi-module Go project, and individual go.mod/go.sum files were created for the demo, integration-test, and shared packages (auth, entity, httpserver, logger, messaging, pagination).
