用javascript直接连接到redis？

Question

This is referring to a previous post made on Stackoverflow asked 3 yrs ago (Connecting directly to Redis with (client side) javascript?). Are there any updates on how to call redis pub/sub from Javascript? (Other than the webdis option the chosen answer showed). I have a redis php script that is able to subscribe from php but I am having trouble calling from Javascript and getting the response. I have tried making a ajax get with jquery and it times out. Any updates would be helpful.
