Error Handling

This one brings together the unglamorous but critical stuff that separates hobby projects from production systems. You get error hierarchies for TypeScript, Python, and Go, structured logging with correlation IDs, and patterns like circuit breakers and graceful degradation. What I appreciate is the anti-pattern callouts: it explicitly shows you the wrong way (bare excepts, swallowing errors, ignoring Go errors) next to the correct approach. The React error boundary example and Express middleware are ready to copy. If you're moving past console.log debugging or need to add observability to an existing codebase, this gives you the patterns without the theory overload.

Error Handling Workflow

Copy this checklist and track progress:

Error Handling Progress:
- [ ] Step 1: Define error taxonomy (categories and severity)
- [ ] Step 2: Implement error handling by layer
- [ ] Step 3: Set up structured logging
- [ ] Step 4: Add retry and circuit breaker patterns
- [ ] Step 5: Configure error tracking service
- [ ] Step 6: Define user-facing error messages
- [ ] Step 7: Validate against anti-patterns checklist
