Demonstrates how to lookup Geolocation data for an IPv4 address using the ip-api.com API. React Native

import { Http, JsonObject } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const http = new Http();

  // Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
  let jsonStr: string;
  try {
    jsonStr = await http.quickGetStrAsync('http://ip-api.com/json/149.250.207.170');
  } catch {
    console.log(http.lastErrorText);
    return;
  }

  const json = new JsonObject();
  json.emitCompact = false;
  json.load(jsonStr);

  console.log(json.emit());
