CI CD and System Overview

Introduction

Project Overview

The Language Learning AI Game's application structure is made to provide a stable, expandable, and maintainable system. It is made up of the following essential parts: CI/CD pipeline, database, messaging queue, and API backend. Every one of these elements is essential to the application's overall performance and usefulness.

Application Structure

Backend API

The backend services are built with PHP and the Laravel framework, ensuring that the application is both resilient and scalable. The rich capabilities and design of Laravel make it easier to build a high-performance backend.

• MVC design: Laravel's Model-View-Controller design separates business logic, user interface, and data administration, allowing for code maintainability and scaling.
• RESTful APIs expose endpoints for front-end interactions, including user authentication, content delivery, and progress monitoring.
• Middleware: implements security elements like as authentication and authorization to ensure that the application is accessed securely.

Database

PostgreSQL is used to manage both user data and application content. To maintain data integrity and security, the database is configured with different instances for the development and production environments.

• User Data Management: Maintains user data, such as preferences, progress, and credentials.
• Content management: Manages language learning content, such as lessons, quizzes, and resources.
• Database Migrations: Versions and manages database schema changes efficiently by utilizing Laravel's migration mechanism.

Messaging Queue

Redis is used as the messaging queue to handle background tasks and service communication, improving application performance and user experience. By offloading time-consuming tasks to a separate queue, the system can process requests more efficiently.

• Task scheduling: Plans out background operations including content updates, data processing, and email notifications.
• Service Communication: Enables dependable data flow and task management by facilitating communication between various backend services.
• Scalability: Prevents performance degradation by enabling the system to manage a large number of jobs.

CI/CD

Continuous Integration and Delivery are ensured by automating the build, test, and deployment processes with GitHub Actions. This configuration guarantees that the application is always in a deployable state and expedites the development process.

• Automated Builds: Compiles and packages the application whenever code is pushed to the repository.
• Automated Testing: Runs unit and integration tests to verify that new code changes do not introduce bugs.
• Continuous Deployment: Deploys the application to the server automatically after successful builds and tests, ensuring rapid and reliable updates.
