Struggling with a function that accesses data from a JSON file and queries it for a specific key. Unfortunately, the return function seems to be executing before the query can find the key.
Even after querying and attempting to return the variable queryresponse within the query function, it consistently returns undefined.
var jsonQuery = require('json-query');
var fs = require('fs');
function querydb(netdomain){
fs.readFile('./querykeys.json', 'utf8', function (err, data) {
if (err){console.log('error');}
var obj = JSON.parse(data);
var queryobject = netdomain.toString();
var queryresponse = jsonQuery('servers[netshare=' + queryobject + '].netdomain', {
data: obj
});
return queryresponse;
});
}
console.log(querydb('timeline'));
// results in undefined.
Looking for a way to make this statement asynchronous. Any suggestions on how to achieve this?
I should mention that I also attempted the following code, but unfortunately, still getting undefined responses.
var jsonQuery = require('json-query');
var fs = require('fs');
function querydb(netdomain){
fs.readFile('./querykeys.json', 'utf8', function (err, data) {
if (err){console.log('error');}
var obj = JSON.parse(data);
var queryobject = netdomain.toString();
return jsonQuery('servers[netshare=' + queryobject + '].netdomain', {
data: obj
});
});
}
console.log(querydb('timeline'));
Appreciate any assistance you can offer!
