auth_id: user.id,
username: user.name,
name: user.name

// Output node properties.
console.log(node.data);
// Output node id.
console.log(node.id);
// RECEIVED node.id ? ONLY THEN SEND IT TO THE FUNCTION THAT NEEDS IT
send_neo_id(node.id);
});
// THIS IS THE FUNCTION THAT WAS NOT RECEIVING NODE.ID BEFORE:functionsend_neo_id(neo_id) {
user.neo_id = neo_id;
db.set('user:id:' + user.name, id, function(err) {
if (err) returnfn(err);
db.hmset('user:' + id, user, function(err) {
fn(err);
});
});
};
