YouTube API V3 for C# Development

Overview

This project aims to develop a YouTube API V3 client for C# applications, making it easier to interact with YouTube data. The official Google.Apis.YouTube.v3 library provides extensive features but is complex and not well-suited for Dependency Injection (DI). This project will implement the YouTube API using a DI-friendly approach to create a more flexible and testable structure.

Goals

• Implement YouTube API functionality based on the official YouTube API Reference to overcome the limitations of Google.Apis.YouTube.v3.
• Utilize C# Dependency Injection to create a highly flexible and testable structure.
• Provide an extensible and maintainable API for developers to interact with YouTube data.

Features

1. Authentication & Authorization

• Integrate Google login for account access using ASP.NET Core Google login functionality.
• Support API key access for simpler use cases.

2. Full YouTube API Implementation

• Implement all functionalities provided in the YouTube API V3 Reference:
  • Video Search: Search for videos based on keywords.
  • Channel Info: Retrieve basic information and statistics for a channel.
  • Playlist Management: Create playlists, add videos, and remove videos.
  • Video Upload & Management: Upload, edit, and delete videos.
  • Comment Management: View, post, and delete comments on videos.
  • Subscription Management: Subscribe to and unsubscribe from channels.
  • Live Streaming Management: Set up, start, and end live streams.

3. Dependency Injection Support

• Separate service interfaces and implementations to facilitate DI container registration.
• Enable easy mocking for unit tests by supporting DI.

System Architecture

• API Client Layer: Handles HTTP communication for YouTube API requests.
• Business Logic Layer: Manages user requests and interacts with the client layer to fetch necessary data.
• Dependency Injection Configuration: Register IYouTubeService and its implementation in Startup.cs for DI usage throughout the application.

Development Environment

• Language & Framework: C#, .NET Core 6.0+
• Dependency Injection: Built-in DI framework
• HTTP Communication: HttpClient

Development Approach

This project will follow a Test-Driven Development (TDD) approach, developing each feature in the following order:

1. Interface Design: Define service interfaces to establish clear contracts.
2. Testing: Write unit tests for the interfaces using TDD principles.
3. Implementation: Develop the classes that fulfill the interface requirements and ensure all tests pass.

Roadmap

1. Setup & Initial Structure Design

   • Initialize the project and set up the directory structure.
   • Design service interfaces that support DI.

2. Full YouTube API Implementation with TDD

   • Implement video search, channel info, playlist management, video upload, comment management, subscription management, and live streaming features using TDD.

3. Testing & DI Integration

   • Write unit tests using mocking.
   • Verify DI integration and set up the test environment.

4. Final Review & Documentation

   • Code review and refactoring.
   • Write developer and user guide documentation.

Benefits

• Overcome the limitations of the existing library and efficiently interact with YouTube data.
• Achieve a flexible and testable structure through DI, making future maintenance and development easier.
• Provide optimized YouTube integration tailored to project requirements.
• Ensure high code quality and reliability by using TDD throughout the development process.
