Another posible solution is for example for REST API in NODE JS:

var name = req.body;//Body is a objetc that has properties for example provinces
var databaseRB = "DATABASENAME"
var conStringRB = "postgres://"+username+":"+password+"@"+host+"/"+databaseRB; 

var filter_query = "SELECT row_to_json(fc) FROM ( SELECT 'FeatureCollection' As type, array_to_json(array_agg(f)) As features FROM (SELECT 'Feature' As type, ST_AsGeoJSON(lg.geom)::json As geometry, row_to_json((parameters) As properties FROM radiobases As lg WHERE lg.parameter= ANY($1) )As f) As fc";

var client = new pg.Client(conStringRB);
client.connect();
var query = client.query(new Query(filter_query,[name.provinces]));
query.on("row", function (row, result) {
  result.addRow(row);
});
query.on("end", function (result) {
 var data = result.rows[0].row_to_json
   res.json({
     title: "Express API",
     jsonData: data
     });
});

Keep in mind that any type of array can be used
