# Hacker News API Integration ## Overview This project integrates with the `Hacker News API` (https://github.com/HackerNews/API) to fetch and cache the best stories. Designed as a read-biased in-memory temporal data store, it optimizes for high-read scenarios with efficient caching strategies to minimize external API calls. ## Getting Started ### Prerequisites - .NET 6 SDK or later - An IDE like Visual Studio 2019/2022, Visual Studio Code, or JetBrains Rider - Docker (optional, for containerization) ### Running the Application Clone the repository (It's a private repo, request access if you want to use it): ```bash git clone https://github.com/JordiCorbilla/HackerNewsApi.git ``` ### Navigate to the project directory: ```bash cd HackerNewsApi ``` ### Restore dependencies: ```bash dotnet restore ``` ### Build the project: ```bash dotnet build ``` ### Run the application: ```bash dotnet run --project HackerNewsApi ``` Alternatively, use your IDE's run/debug functionality. ## Access the application: The application will be available at [https://localhost:7007 or http://localhost:5171](https://localhost:7007/swagger/index.html) by default.  ## Using Docker (Optional) To containerize the application, ensure Docker is installed and running, then: ### Build the Docker image: ```bash docker build -t hackernewsapi . ``` ### Run the container: ```bash docker run -p 8080:80 hackernewsapi ``` The application will now be accessible at https://localhost:49155/swagger/index.html.  ## Assumptions - The Hacker News API remains stable and backward compatible. - The application takes into account a safe-threading in-memory caching mechanism to avoid hitting the Hacker News API. - The kids property has been left as it is (without continue fetching news). - The application is primarily read-heavy, with frequent fetches for the best stories. - Network latency and reliability between the application and the Hacker News API are not significant concerns. - API Documentation: I have utilized Swagger/OpenAPI for API documentation to make the service more discoverable and easier to use for developers. ## Enhancements Given more time, the following enhancements could be considered: - Implement Distributed Caching: To better support scalability and high availability, integrating a distributed cache like Redis would be beneficial. - Add Resilience Patterns: Implementing resilience patterns such as retries with exponential backoff, circuit breakers, and bulkheads would help improve the robustness of external API calls. - Enhance Logging and Monitoring: Integrating with a centralized logging platform and adding more detailed metrics would facilitate better observability and troubleshooting. - Automated Testing: Expanding the test suite to cover more scenarios, including performance and load testing, would ensure the application's reliability and scalability. - Security Enhancements: Adding authentication, rate limiting, input validation, and securing sensitive configuration settings would improve the application's security posture.
