🇧🇩 Introducing @olism/bd-geo — Bangladesh Geographic Data for JavaScript & TypeScript

Md. Oliullah Sarder — Tue, 25 Aug 2026 10:35:59 +0000

🚀 I'm excited to share my new open-source npm package: @olism/bd-geo.

@olism/bd-geo is a JavaScript/TypeScript package that provides structured geographical data for Bangladesh, including divisions, districts, upazilas/thanas, areas, and villages.

The goal is simple: make it easier for developers to work with Bangladesh's geographical hierarchy without having to maintain their own datasets.

✨ What is `@olism/bd-geo`?

When building applications that need Bangladesh-specific location data, developers often have to find, clean, structure, and maintain geographical datasets themselves.

This package provides that data in a developer-friendly structure that can be used directly in JavaScript and TypeScript projects.

🗺️ What's Included?

The package currently provides geographical data such as:

🇧🇩 Divisions
📍 Districts
🏘️ Upazilas / Thanas
📌 Areas
🏡 Villages

This makes it suitable for applications that need hierarchical location data.

💡 Potential Use Cases

@olism/bd-geo can be useful for many types of applications, including:

📝 Address and location forms
🛒 E-commerce and delivery systems
🏠 Real-estate applications
🗺️ Location-based applications
🗄️ Database seeding
📊 Data visualization
🔎 Location search and filtering

For example, an address form could use the geographical hierarchy to let users select:

Division
   ↓
District
   ↓
Upazila / Thana
   ↓
Area / Village

📦 Installation

Install the package from npm:

npm install @olism/bd-geo

Or with Yarn:

yarn add @olism/bd-geo

🚀 Why I Built It

I wanted to make Bangladesh geographical data easier to consume for developers building real-world applications.

Instead of every project maintaining its own copy of Bangladesh's location data, a reusable package can provide a common structure that developers can work with directly.

There is still plenty of room to improve the dataset, APIs, documentation, and developer experience — and that's where community feedback can make a big difference.
