How I Solved the Pakistan Address & City Data Problem for MERN Developers

Описание и применение

Разработчик создал npm‑пакет @pakistan-address/react, заменив устаревшие JSON‑файлы на структурированные данные о провинциях, делениях, районах и техсилах Пакистана, а также реальные зоны доставки курьеров.

Задача

Developers building e-commerce or delivery apps in Pakistan usually rely on outdated, broken GitHub Gists. These flat JSON files lack relational structure, miss newly formed districts, and ignore how local courier networks actually operate.

Результат

The package replaces outdated flat JSON files with a reliable, maintained source of structured address data, improving accuracy and developer experience.

Рабочий процесс

• Identify outdated address data sources
• Design a plug‑in npm package
• Implement normalized official hierarchy
• Add unofficial courier delivery zones
• Publish package to npm
• Integrate package into MERN stack app

I engineered a plug-and-play npm package to permanently solve this data headache:

Accurately maps the structured hierarchy of Provinces → Divisions → Districts → Tehsils.

Источник

Includes distributed real-world delivery zones. Government boundaries rarely match how local logistics work on the ground; this dataset bridges that gap for realistic checkout flows.

Источник

Built with TypeScript to catch data errors at compile time, not during a user's checkout.
