Homework: Our Best SaaS

=====================================================

Introduction

In this assignment, we will design and implement a Spring Boot application that interacts with the GitHub API to monitor repositories. This application will enable users to track their favorite repositories, view recent activities, set up custom alerts, and get aggregated statistics across all tracked repositories.

Learning Objectives

Design and Implement a Well-Structured Spring Boot Application

The primary objective of this assignment is to design and implement a well-structured Spring Boot application that meets the functional requirements outlined below. This includes creating a robust and scalable architecture, implementing proper error handling and validation, and applying software engineering principles from class.

Create RESTful APIs Following Best Practices

We will create RESTful APIs that follow best practices, including using HTTP methods correctly, handling errors and exceptions, and implementing proper authentication and authorization mechanisms.

Integrate with Third-Party APIs (GitHub)

We will integrate our application with the GitHub API to fetch updates from tracked repositories. This includes implementing proper error handling for GitHub API rate limits and failures.

Implement Proper Error Handling and Validation

We will implement proper error handling and validation mechanisms to ensure that our application handles errors and exceptions correctly. This includes implementing try-catch blocks, logging errors, and providing meaningful error messages to users.

Apply Software Engineering Principles from Class

We will apply software engineering principles from class, including the SOLID principles, to ensure that our application is maintainable, scalable, and easy to test.

Practice Documentation and Testing

We will practice documentation and testing by writing unit tests, integration tests, and end-to-end tests to ensure that our application works as expected.

Functional Requirements

Register and Track GitHub Repositories

Users should be able to register and track GitHub repositories they want to monitor. This includes creating a repository model, implementing a repository service to interact with the GitHub API, and storing relevant data in a database.

View Recent Activities

Users should be able to view recent activities (commits, pull requests, issues, releases) from tracked repositories. This includes implementing a recent activities service to fetch updates from the GitHub API and storing relevant data in a database.

Set Up Custom Alerts

Users should be able to set up custom alerts for specific events (e.g., new release, issue with specific labels). This includes implementing an alert service to store custom alert configurations and sending notifications to users when specific events occur.

Get Aggregated Statistics

Users should be able to get aggregated statistics across all tracked repositories. This includes implementing a statistics service to fetch aggregated data from the database and providing meaningful statistics to users.

System Requirements

Periodically Poll the GitHub API

The system should periodically poll the GitHub API to fetch updates from tracked repositories. This includes implementing a scheduled task to fetch updates at regular intervals.

Store Relevant Data in a Database

The system should store relevant data in a database to minimize GitHub API calls. This includes implementing a database schema to store repository data, recent activities, and custom alert configurations.

Implement Proper Error Handling

The system should implement proper error handling for GitHub API rate limits and failures. This includes implementing try-catch blocks, logging errors, and providing meaningful error messages to users.

Implementation

Project Structure

Our project structure will consist of the following modules:

  • com.homework.saa: The main application module.
  • com.homework.saa.repository: The repository module that interacts with the GitHub API.
  • com.homework.saa.service: The service module that provides business logic for the application.
  • com.homework.saa.dao: The data access object module that interacts with the database.
  • com.homework.saa.util: The utility module that provides helper classes and methods.

Repository Module

The repository module will be responsible for interacting with the GitHub API to fetch updates from tracked repositories. This includes implementing a GitHubRepository class that provides methods to fetch repository data, recent activities, and custom alert configurations.

Service Module

The service module will be responsible for providing business logic for the application. This includes implementing a RepositoryService class that provides methods to register and track repositories, view recent activities, set up custom alerts, and get aggregated statistics.

DAO Module

The DAO module will be responsible for interacting with the database to store and retrieve data. This includes implementing a RepositoryDAO class that provides methods to store and retrieve repository data, recent activities, and custom alert configurations.

Utility Module

The utility module will provide helper classes and methods that can be used throughout the application. This includes implementing a Logger class that provides methods to log errors and a Validator class that provides methods to validate user input.

Testing

Unit Tests

We will write unit tests to ensure that each module works as expected. This includes writing test cases for the repository module, service module, DAO module, and utility module.

Integration Tests

We will write integration tests to ensure that the application works as expected. This includes writing test cases for the repository module, service module, and DAO module.

End-to-End Tests

We will write end-to-end tests to ensure that the application works as expected. This includes writing test cases for the application's user interface and business logic.

Conclusion

In this assignment, we designed and implemented a Spring Boot application that interacts with the GitHub API to monitor repositories. We implemented a well-structured application that meets the functional requirements outlined above. We also applied software engineering principles from class, including the SOLID principles, to ensure that our application is maintainable, scalable, and easy to test.
