🗺 A lightweight Typescript wrapper for the Country.is API with first-class support for Node.js and modern browsers. This package provides a clean, promise-based interface for retrieving country-location information without needing to manage raw fetch logic yourself. Original API Source: https://country.is/
npm install country-is- TypeScript-first with full type support
- Simple promise-based API for Node.js and modern browsers
- Supports package info, caller location lookup, IP-based lookup and multi-IP lookup
- Supports optional field selection for enriched payloads
- Minimal runtime footprint and tree-shake friendly packaging
- 📁 Get Package Info:
Fetches service metadata and package details from the API with zero config overhead
/* node modules */
import { getCountryIsInfo } from 'country-is';
async function myFunc() {
try {
const response = await getCountryIsInfo();
console.log(response);
} catch (error) {
console.error('Failed to get package info:', error);
}
}
await myFunc();- 📁 Get Caller Location Info
Returns caller IP-based location info with optional field selection for a tailored payload.
/* node modules */
import { getCallerLocInfo } from 'country-is';
async function myFunc() {
try {
/*
fields: can be either = "default"
or an array of atleast one: ['city', 'continent', 'subdivision', 'postal', 'location', 'asn']
*/
const response = await getCallerLocInfo({ fields: 'default' }); // use 'default' or an array of predefined fields
console.log(response);
} catch (error) {
console.error('Failed to get caller location info:', error);
}
}
await myFunc();- 📁 Get Location Info by IP
Fetches location data for a given IP and supports optional fields to limit the payload data.
/* node modules */
import { getLocInfoByIP } from 'country-is';
async function myFunc() {
try {
/*
fields: can be either = "default"
or an array of atleast one: ['city', 'continent', 'subdivision', 'postal', 'location', 'asn']
*/
const response = await getLocInfoByIP({
ip: '1.1.1.1',
fields: ['continent', 'asn'],
});
console.log(response);
} catch (error) {
console.error('Failed to get location info by IP:', error);
}
}
await myFunc();- 📁 Get Location Info for Multiple IPs
Submits a batch of IP addresses to Country.is and returns location payloads with optional fields.
/* node modules */
import { getMultiCallerLocInfo } from 'country-is';
async function myFunc() {
try {
/*
fields: can be either = "default"
or an array of atleast one: ['city', 'continent', 'subdivision', 'postal', 'location', 'asn']
*/
const response = await getMultiCallerLocInfo({
ips: ['1.1.1.1', '2.2.2.2'],
fields: ['continent', 'asn'],
});
console.log(response);
} catch (error) {
console.error('Failed to get multi-caller location info:', error);
}
