Furkan-Gulsen/golang-url-shortener

The application now includes concrete repository implementations for managing link data and usage statistics via AWS DynamoDB. New files, link.go and stats.go, provide the data access layer for the Link and Stats domains, implementing methods to create, read, update, and delete records in DynamoDB tables. This enables the core domain logic to interact with persistent storage for both URL shortening and analytics features.

internal/adapters/repository · high confidence

The application now exposes HTTP handlers for creating, deleting, and redirecting short links, as well as retrieving link statistics. A new Redis cache adapter is introduced for data storage. Additionally, the system now sends messages to an AWS SQS queue upon link creation and integrates with Slack to post notifications.

internal/adapters/handlers · high confidence

The application now uses a centralized configuration module to manage environment variables for DynamoDB, Redis, and Slack. Users can now configure the DynamoDB table names, Redis connection details (address, password, DB), and Slack integration tokens via environment variables, with sensible defaults provided for local development.

internal/config · high confidence

Added new service implementations for managing links and statistics, each delegating to corresponding ports (LinkPort, StatsPort, and Cache) to handle data operations. The LinkService provides methods to retrieve, create, and delete links, while the StatsService manages statistics data, including retrieving stats by link ID. Both services wrap port interactions with error handling, ensuring that failures in underlying data access are properly propagated.

internal/core/services · high confidence

The application now deploys dedicated AWS Lambda functions for each core operation: generate, redirect, delete, stats, and a notification handler for Slack. Each function wires up the corresponding service (link or stats) with its repository and cache, exposing a specific entry point (e.g., CreateShortLink, Delete, Redirect, Stats) to the cloud environment.

internal/adapters/functions · high confidence

The application's internal core now exposes explicit interface-based ports for cache operations, link management, and statistics. These new ports define the contracts for interacting with external services and the domain layer, supporting a shift toward a hexagonal architecture. Specifically, the Cache, Link, and Stats ports each provide methods for CRUD operations and data retrieval, allowing the core logic to remain decoupled from specific implementations.

internal/core/ports · high confidence

Added new domain structures for the application's core entities. The Link model now includes a CreatedAt timestamp and a collection of Stats. A new Stats model has been introduced, featuring a Platform enum to categorize metrics by source (Instagram, Twitter, or YouTube), each with its own ID, associated LinkID, and creation timestamp.

internal/core/domain · high confidence

Added benchmark tests for link service; Added mock implementations for link and stats repositories; Added unit tests for link generation, redirection, stats, and Slack integration.

Introduced go.mod and go.sum files to define the project's Go module path (github.com/Furkan-Gulsen/golang-url-shortener) and lock in specific versions of dependencies, including AWS SDKs, Redis, and Slack libraries.
