How to get valid address through #google/maps? - node.js

Question

In Node.js microservice I'm using:
"#google/maps": "^0.5.5"
googleMapsClient.geocode({address: '160 Market St, Paterson, NJ 07505'})
.asPromise()
.then((response) => {
console.log("result: " + JSON.stringify(response.json));
})
.catch((err) => {
console.log("error: " + err);
});
in response I get: "location_type":"ROOFTOP" and "types":["street_address"] that means the address is valid
If I try to validate same address but with invalid state, e.g. 'NO' it still returns "location_type":"ROOFTOP" and "types":["street_address"]. Assume because google API formats it that can be seen in the response:
"formatted_address":"160 Market St, Paterson, NJ 07505, USA"
Sometimes google API returns "location_type":"ROOFTOP" and "types":["premise"]
Sure I can filter the results by location_type and types but I really want to consider address as valid if it can be found in #types/googlemaps AutoComplete. This is what I'm using in UI (Angular):
"#types/googlemaps": "3.30.16"
const autocomplete = new google.maps.places.Autocomplete(e.target, {
types: ['address']
});
var place = google.maps.places.PlaceResult = autocomplete.getPlace();
Even it's just defined as types: ['address'] in AutoComplete it can be found as "types":["street_address"] or "types":["premise"] in "#google/maps"..
So how make Node.js returns only addresses that can be found in AutoComplete?

Answer 1

Since Places API is also supported by #google/maps library, it could be accomplished like this:
//1. query predictions
googleMapsClient.placesQueryAutoComplete(
{
input: "160 Market St, Paterson, NJ 07505"
},
function(err, response) {
if (!err) {
if (response.json.predictions.length === 0) {
console.log("Place not found");
} else {
var prediction = response.json.predictions[0]; //select first prediction
//2. query place by prediction
googleMapsClient.place(
{
placeid: prediction.place_id
},
function(err, response) {
if (!err) {
console.log(response.json.result); //prinat place
}
}
);
}
}
}
);
Explanation:
placesQueryAutoComplete function is utilized first which returns array of query predictions based on query
place function returns the place details by providing placeId parameter extracted from previous response
