A while ago, I was looking for Indonesian regional data for one of my projects.
Most of the datasets I found came as large MySQL dumps, which required importing into a database just to access provinces or districts.
Then I found the file wilayah.sql from cahyadsn/wilayah.
It contains complete administrative data — provinces, cities, districts, and villages across Indonesia.
I tried to process it so developers could use it directly — no database setup, no SQL import.
After cleaning and compressing it with Brotli, the raw data size went from ~2.5 MB down to only ~420 KB.
The result is Nusantara-API 🚀
A small library for accessing Indonesian regional data — usable in Node.js, frontend, or directly via CDN.

- Source DB (MySQL dump): github.com/cahyadsn/wilayah
- npm: npmjs.com/package/nusantara-api
- Demo: ibnushahraa.github.io/nusantara-api
Sometimes small experiments end up becoming something useful for others.
This project started as a simple curiosity — and turned into a compact, shareable dataset for developers who just need quick access to Indonesian regions.
