Taking the habit tracker from MVP to production-ready with categories, analytics, comprehensive testing, and Vercel deployment

Welcome Back!

In [Part 1] , we built a fully functional habit tracker MVP in about 6-8 hours using Claude Code as our AI pair programmer. We had:

✅ Basic CRUD operations for habits

✅ Date-based tracking

✅ Dark/light theme toggle

✅ localStorage persistence

✅ Simple analytics

So continuing my learning journey with Claude as I will be covering below topics and how I used claude to plan and work on them
