Fast country data

Case Study Overview

Built to communicate the challenge, the approach, and the outcome with clarity.

A security-hardened country lookup experience built to stay fast, cache-friendly, and API-first. The raw dataset is protected — search returns only matched results, never the full list in one shot.

Country codes, flags, and dial prefixes in one clean place.

A security-hardened country lookup experience for countrycode.peakiq.in, built to stay fast, cache-friendly, and API-first.

The raw JSON dataset is protected — search returns only limited matching results instead of exposing the full country list in a single response.

What it does

This country code tool helps developers find dial codes, ISO country codes, unicode flags, and inline SVG flag markup through a searchable web interface and REST API.

Example — India

Field	Value
Dial code	`+91`
ISO code	`IN`
Unicode	`U+1F1EE U+1F1F3`

Features

🔒 Protected dataset

The raw JSON file is hidden. Search fetches only a small set of matching results, so the full country list is never exposed in a single response.

🏳️ Inline flag preview

SVG flags are rendered inline — browsing countries no longer requires a separate flag asset request per country.

⚡ Local-first browsing

After the first page load, search and filtering stay lean so the project remains a clean public showcase.

🛠️ API access

Use code-based endpoints instead of downloading the full dataset.

GET /api/country/IN          → lookup a single country
GET /api/countries?search=india  → search matching countries

Live endpoints:

Browsing

Browse all countries →

Type at least 2 characters to fetch a small set of matching countries from the API.
