Same logic. Same output. Completely different quality. Before: Inline SQL with string concatenation. No error handling. Hardcoded strings. No input validation. Nested callbacks 3 levels deep. After: Parameterized queries with Drizzle ORM. Try-catch with proper error responses. Zod schema validation. Async-await with flat structure. 5 issues fixed. Zero functionality changed. One prompt. Two minutes. The exact prompt: "Refactor this component following best practices. Fix all ESLint warnings. Add proper TypeScript types. Replace inline styles with Tailwind. Add loading and error states. Do not change the external API or props interface." 40+ refactoring prompts — link in the description. --- TIMESTAMPS --- 0:00 - The 2 AM code 0:12 - What's wrong with it 0:25 - The AI-refactored version 0:38 - The exact prompt 0:50 - Results #AIcoding #Refactoring #CodeQuality #ClaudeCode #VibeCoding #TypeScript #BestPractices #endofcoding
