Installation 📥

npm install d8r
# or
yarn add d8r

Usage 🚀

// Modern ES imports
import { parseDate, formatDate } from 'd8r';

// Parse dates
const date = parseDate('2024-01-15', 'YYYY-MM-DD');
console.log(formatDate(date, { format: 'DD/MM/YYYY' })); // "15/01/2024"

// Date arithmetic
import { addDays } from 'd8r/core';
const futureDate = addDays(date, 5);

The library is almost production-ready with: ✅ Type definitions ✅ Test coverage ✅ Build configuration ✅ Package exports ✅ Documentation

Final checklist before publishing:

1. Run npm run test (verify all tests pass)
2. Run npm run build (check dist output)
3. Run npm pack (test package locally)
4. Review documentation
5. Check bundle size with npm run analyze

Would you like me to help implement any of these final items?
