Simple-proxy-id — A tiny yet secure proxy for Node.js (zero dependencies)

🧠 From a Small Frustration to a Tiny but Powerful Proxy

A few weeks ago, I just needed a small proxy for testing local APIs.
Something that just works — no heavy setup, no extra dependencies, no magic.

But as usual, once something works, developers can’t resist improving it 😅
That’s how simple-proxy-id was born.

It’s a lightweight HTTP/HTTPS proxy for Node.js,
built with zero dependencies, yet still secure, fast, and flexible.

🔧 Why I Built It

While working with APIs, I noticed two extremes in most proxy libraries:

They’re too flexible, which often leads to open-proxy abuse.
Or too limited, making them hard to use in real server environments.

So I aimed for something in between — secure, simple, but production-ready.

⚙️ Quick Example

import { createProxy } from "simple-proxy-id"

createProxy({
  target: "https://jsonplaceholder.typicode.com",
  port: 3000,
  changeOrigin: true,
  pathRewrite: { "^/api": "" },
})

That’s it — your proxy is up and running.
No config files, no dependencies, no magic behavior.

⚡ Key Features

✅ Fixed target — cannot be changed by external requests (prevents open proxy abuse)
✅ Path rewrite — support for both pattern objects and custom functions
✅ Plugins — CORS, daily rotating logger, brute-force attack detection
✅ Real IP detection — supports Cloudflare Tunnel and X-Forwarded-For
✅ Zero dependency, high performance — ~1,660 req/sec (p50: 52 ms, p99: 138 ms)

No frameworks, no dependencies — just pure Node.js, connection pooling,
and a lot of small optimizations to make it perform well under load.

🧩 Why It Matters

The project started from a small frustration —
but sometimes that’s exactly where useful tools come from.

If you often deal with API testing, debugging, or quick proxy setups,
you might find this handy 👇

Sometimes the best open-source projects don’t start with a plan —
they start with one small problem you just couldn’t ignore.

🌏 Nusantara-API 🇮🇩 — from MySQL dump to a tiny 420 KB library

Muhammad Syarwani — Sat, 11 Oct 2025 01:26:30 +0000

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.

🔗 Links

GitHub: github.com/ibnushahraa/nusantara-api
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.

🧮 Introducing number-to-words-id — Convert Numbers to Words in 3 Languages

🧮 I Built a Library to Convert Numbers into Words in 3 Languages

Have you ever needed a “terbilang” function in your project?
When I worked on billing and invoice systems, I realized that most libraries only support English — none for Indonesian or Malay.
So I decided to create number-to-words-id.

It’s a lightweight Node.js library that converts numbers into words in Indonesian, Malay, and English — all offline, no dependencies.

🚀 Quick Example

import { toWords } from "number-to-words-id";

console.log(toWords(75000)); 
// "tujuh puluh lima ribu"

console.log(toWords(75000, { lang: "en" }));
// "seventy-five thousand"

console.log(toWords(75000, { lang: "ms" }));
// "tujuh puluh lima ribu"

⚙️ Features

🇮🇩 Indonesian, 🇲🇾 Malay, 🇬🇧 English
Currency and ordinal support
Clean, dependency-free JavaScript
Tiny size and fast performance

💡 Why I Built It

Because every time I saw terbilang(12345) in projects, it was always a custom function someone copied from StackOverflow 😅
Now, we have a proper open-source version — tested, maintained, and versioned on npm.
