🎵 "Vibe Coding" কী?
২০২৫-এর trend (Andrej Karpathy)। Code line-by-line না লিখে — high-level intent describe করেন, AI implement করে। আপনি direct/redirect করেন।
"Make a todo app. Add categories. The dragging should feel smooth. Make it Bengali-friendly." → AI builds full app → You test, give feedback → AI iterates → Ship
🆚 Traditional vs Vibe
| Traditional | Vibe Coding |
|---|---|
| Function-by-function | Feature-level intent |
| Type each line | Describe outcome |
| Read every file | Trust AI, spot-check |
| Manual debug | Paste error, AI fix |
| Hours/days | Minutes/hours |
✅ Vibe Coding কখন ভালো
- Prototype, MVP
- Personal project
- Small/throwaway script
- UI experimentation
- Quick proof-of-concept
- Learning new framework
❌ কখন এড়াবেন
- Production critical (security, payment)
- Compliance-heavy (HIPAA, finance)
- Performance critical
- Long-lived complex system
- Team collaboration heavy
📐 Spec-Driven Development ⭐
Vibe-এর evolved version — formal spec লিখে AI কে দেন।
Spec Document Structure
# Feature: User Authentication ## Requirements - Email + password login - OAuth: Google, GitHub - Forgot password flow - Email verification - Rate limit 5 attempt/min ## Non-functional - Latency: <500ms login - Security: bcrypt, JWT 1h, refresh 30d - GDPR compliant ## Edge Cases - Locked account - Disabled user - Concurrent login - Stale token ## Out of Scope - 2FA (next iteration) - SSO enterprise ## Success Criteria - All tests pass - Lighthouse > 90 - Manual smoke test pass
🛠️ Workflow
1. Human: Spec write (markdown) 2. AI: Read spec, ask clarifying questions 3. Human: Answer 4. AI: Implementation plan 5. Human: Approve / adjust 6. AI: Code 7. AI: Tests against spec 8. Human: Acceptance test 9. Iterate
🎨 Tools for Vibe
- v0.dev — UI from prompt
- Bolt.new — full-stack from prompt
- Lovable — app builder
- Replit Agent — autonomous build
- Cursor Composer — multi-file edit
- Windsurf Cascade — agentic dev
- Claude Code — CLI agent
💡 Effective Vibe Prompt
❌ "Build me a website" ✅ "Build a landing page for a SaaS product: - Hero with headline + CTA - 3 feature cards - Pricing table (3 tiers) - FAQ accordion - Footer with social link - Vercel deploy ready - Tailwind, shadcn/ui - Dark mode toggle - Mobile-first - TypeScript strict"
🔄 Iteration Pattern
"Make the hero bigger" "Hero text feels weak — punchier" "Pricing card hover should glow" "Mobile menu broken on iPad — fix" "Add trust badges below hero" // Continuous refinement, like product designer
⚠️ Risk Awareness ⭐
- Tech debt — clean না হয়, hidden complexity
- Security gap — AI default insecure
- Performance — N+1 query, bundle bloat
- Maintenance — কে maintain করবে?
- Knowledge silo — code-base বুঝে না কেউ
- Hallucinated library
- Test gap
✅ Hybrid Approach (Recommended)
Vibe coding: scaffolding, UI, prototype Spec-driven: feature implementation Traditional review: security, performance, architecture Manual: business logic critical path
🎯 Career Implication
- Junior — শিখার speed বাড়ছে
- Mid — productivity 3-5x
- Senior — focus shift to architecture, review, mentor
- Code-only role decreasing
- System design value বাড়ছে
- Communication skill premium
🔮 Future of Coding
Code = English ক্রমে। Programmer = product manager + architect + reviewer + AI orchestrator। Skill: judgment, taste, system thinking।
