Getting connection value outside of master/slave function

[gurinder-sason]

Hi
i am using this npm for making mysql cluster, but i stuck at one place. Below code make connection inside slave function. I want to move connection outside this function so that no need to copy this code to execute query each time. currently getting undefined as it is called after the calback

cluster.slave(function(err, conn) {
if(!err) {
conn.query('select * from test limit 10', function(err, result, fields) {
// do something
conn.release(); // Put the connection back into pool.
}
} else {
console.log('Error, failed to aquire connection);
console.log(err);
}
}
