Web stack debugging #1

• this involves identifying and fixing issues at various levels of the web development stack, including the front end, back end, and the server.

How to approach web stack debugging:

Back-End Debugging:

1. Server Logs:

   Check server logs for errors and warnings.
   Analyze logs to identify patterns or specific issues.

2. Database Debugging:

   Ensure database connections are established correctly.
   > Check database logs for errors.
   > Verify that database queries are returning the expected results.

3. API Testing:

   Test API endpoints using tools like Postman or cURL.
   > Inspect API responses for errors and unexpected behavior.

4. Code Profiling:

   Use profiling tools to identify performance bottlenecks in your server-side code.
   > Profile database queries and optimize slow-performing queries.

Infrastructure Debugging:

1. Server Configuration:

   Verify server configurations for web servers (e.g., Apache, Nginx).
   Check for any misconfigurations that may lead to issues.

2. Load Balancing:

   If applicable, check load balancing configurations.
   Ensure that requests are distributed evenly among server instances.

3. Firewall and Security:

   Check firewall settings for any restrictions.
   Verify that security configurations are not blocking legitimate requests.

4. Resource Monitoring:

   Monitor server resources (CPU, memory, disk space) to identify resource-related issues.
   Use tools like top or server monitoring services.
