This code uses the Google Maps Geocoding API to convert an address ("Kazimierz World Wine Bar") into geographic coordinates (latitude and longitude). It then handles the API response, likely sending the results to a user interface or another part of the application.

Run example

npm run import -- "use Google Geocaching"

use Google Geocaching

var util = require('util');
var request = util.promisify(require('request'));

function googleGeocodeAddress(address) {
    return request('https://maps.googleapis.com/maps/api/geocode/json?address=' + address + '&key=AIzaSyAoTAY0vq2yuaDyygjMdwgharnS_CXEvRY')
        .then(r => JSON.parse(r.body).results)
}

if(typeof $ !== 'undefined') {
    $.async();
    googleGeocodeAddress('Kazimierz World Wine Bar')
        .then(r => $.sendResult(r))
        .catch(e => $.sendError(e))
}

// Import the required libraries
const axios = require('axios');

/**
 * Function to make a GET request to the Google Geocoding API.
 * 
 * @param {string} address - The address to geocode.
 * @param {string} apiKey - The API key for the Google Geocoding API.
 * @returns {Promise} A promise resolving to an array of geocoding results.
 */
async function googleGeocodeAddress(address, apiKey = 'AIzaSyAoTAY0vq2yuaDyygjMdwgharnS_CXEvRY') {
    try {
        // Use axios to make a GET request to the Google Geocoding API
        const response = await axios.get(`https://maps.googleapis.com/maps/api/geocode/json?address=${address}&key=${apiKey}`);
        
        // Parse the JSON response
        return response.data.results;
    } catch (error) {
        // If an error occurs, throw it
        throw error;
    }
}

// Check if $ is defined to avoid runtime errors
if (typeof $!== 'undefined') {
    $.async();
    // Make the geocode request and send the result
    googleGeocodeAddress('Kazimierz World Wine Bar')
       .then(result => $.sendResult(result))
       .catch(error => $.sendError(error));
}

This code snippet demonstrates how to geocode an address using the Google Maps Geocoding API.

Here's a breakdown:

1. Dependencies:

   • util: A built-in Node.js module for utility functions.
   • request: A library for making HTTP requests, promisified using util.promisify for easier asynchronous handling.

2. API Key:

   • The code directly embeds your Google Maps API key in the URL. Important: In a real-world application, it's highly recommended to store your API key securely and not expose it directly in the code.

3. googleGeocodeAddress Function:

   • Takes an address string as input.
   • Constructs a URL to the Google Geocoding API endpoint, including the address and your API key.
   • Uses request to make a GET request to the constructed URL.
   • Parses the JSON response and returns an array of results, each containing geocoding information (latitude, longitude, etc.) for the given address.

4. Execution:

   • The if block checks if a special $ object is available (likely part of a testing or server-side framework).
   • If available, it calls googleGeocodeAddress with the address "Kazimierz World Wine Bar" and handles the result using $.sendResult for success and $.sendError for any errors.
