Convert longitude-latitude pairs to ISO 3166-1 codes quickly and locally
📍 ➡️ 🇩🇰 Convert longitude-latitude pairs to ISO 3166-1 codes quickly and locally
country-coder is a lightweight package that looks up region identifiers for geographic points without calling a server. It can code and convert between several common IDs:
ZA)ZAF)710)710)Q258).za)Results can optionally include non-country ISO 3166-1 features, such as Puerto Rico (PR) or the Isle of Man (IM). Some unofficial yet exceptionally-reserved or user-assigned ISO codes are also supported, such as the European Union (EU) and Kosovo (XK), as well as M49 regions like Africa (002) or Polynesia (061).
In addition to identifiers, country-coder can provide basic regional information:
Client-side coding has a number of benefits over server-side solutions:
country-coder prioritizes package size and lookup speed over precision. Thus, it's not suitable for some situations and use cases:
npm install @rapideditor/country-coder
country-coder is distributed in CJS and ESM module formats for maxmimum compatibility. (Read more about Javascript module formats)
const countryCoder = require('@rapideditor/country-coder'); // CommonJS import all
const iso1A2Code = require('@rapideditor/country-coder').iso1A2Code; // CommonJS import named
// or
import * as countryCoder from '@rapideditor/country-coder'; // ESM import all
import { iso1A2Code } from '@rapideditor/country-coder'; // ESM import named
You can also use country-coder directly in a web browser. A good way to do this is to fetch the "iife" bundle from the jsDelivr CDN, which can even deliver minified versions.
When you load this file in a <script> tag, you'll get a countryCoder global to use elsewhere in your scripts:
<head>
<script src="https://cdn.jsdelivr.net/npm/@rapideditor/country-coder@5.3/dist/country-coder.iife.min.js"></script>
</head>
…
<script>
var result = countryCoder.iso1A2Code('Q145');
</script>
👉 This project uses modern JavaScript syntax for use in supported node versions and modern browsers. If you need support for legacy environments like ES5 or Internet Explorer, you'll need to build your own bundle with something like Babel.
Simply pass in a [longitude, latitude] to iso1A2Code to get the country code.
iso1A2Code([-4.5, 54.2]); // returns 'GB'
To include non-country territories, pass in territory for the level option.
iso1A2Code([-4.5, 54.2], { level: 'territory' }); // returns 'IM'
The same method can convert from other identifiers.
iso1A2Code('Q145'); // returns 'GB'
