Advanced Debugging for Headless Systems

1. Introduction

Debugging headless systems can be challenging due to their lack of a user interface, requiring a different set of tools and strategies. This lesson aims to provide advanced debugging techniques for headless systems within a composable architecture.

2. Key Concepts

• Headless Architecture: A decoupled architecture where the frontend and backend are separate, allowing for flexible content delivery.
• Composable Architecture: A modular approach where components are easily integrated and replaced, providing scalability and maintainability.
• Debugging: The process of identifying, isolating, and correcting issues within software systems.

3. Debugging Strategies

To effectively debug headless systems, consider the following strategies:

1. Logging: Implement comprehensive logging to capture errors and system behavior.
2. Remote Debugging: Use tools like Chrome DevTools or Visual Studio Code for remote debugging of server-side code.
3. API Testing: Use tools like Postman to test API endpoints and ensure correct responses.
4. Performance Monitoring: Utilize APM tools to monitor performance and identify bottlenecks.
5. Unit Testing: Write unit tests to validate individual components and prevent regressions.

4. Best Practices

Following best practices can enhance the debugging process:

• Standardize logging formats across services.
• Automate testing and deployment to catch issues early.
• Document API contracts to avoid mismatches.
• Use version control effectively to manage changes.
• Regularly review code and conduct pair programming sessions.
