Node.js async to sync

Question

How can I make this work

var asyncToSync = syncFunc();

function syncFunc() {
    var sync = true;
    var data = null;
    query(params, function(result){

You can do it with node-sync lib

var sync = require('sync');

sync(function(){
  var result = query.sync(query, params);
  // result can be used immediately
})

Notice: your query must use standart callback call (with error first): callback(error, result). If you can't change query method, just create .async() wrapper (see github link).
