Using the node.js google maps client library - node.js

Question

I think this has to do with my limited experience with javascript.
I am using the node.js client library by Google , found here - https://github.com/googlemaps/google-maps-services-js
The example shows how to create a client object
var googleMapsClient = require('#google/maps').createClient({
key: 'your API key here'
});
And then how to run a gecode request and print out the results :
// Geocode an address.
googleMapsClient.geocode({
address: '1600 Amphitheatre Parkway, Mountain View, CA'
}, function(err, response) {
if (!err) {
console.log(response.json.results);
}
});
What I need to do is read a list of addresses from a file and build an array of objects for all of them .
I want my code to do something along the lines of :
create address-objects array
create a client object
open the text files
for each line in text files
geocode the line(address)
add the address and the results into an object and add it to the address-objects
I don't understand whether the googleMapsClient.geocode returns something , if yes how do I access it ? should I set it to some variable along the lines of :
var gc_results = googleMapsClient.geocode(param , ...)
Hope I was clear , thanks in advance

Answer 1

You can access the response inside the callback function.
So, if you want to have this function to be called for each address, you can first define an empty array:
var gc_results = [];
Then you shall call the function for each address you get out of the file, something similar to this:
addresses.forEach(function(){
googleMapsClient.geocode({
address:
}, function(err, res) {
gc_results.push(res.json.results);
})
})
after this, you will have the gc_results array full with the information you need
