I am working on nodes socket.io redis project.
The real time instant message works fine. However, I am wondering how to store offline message and how to guarantee message delivery.
Anyone has idea on how to implement persistent pub sub using above tech stack ?

It depends on the number of message you want to handle. Take a look here, and I would advice to use AOF style. And if you need something bigger then your RAM, I would recommend to delete message from the queue when its delivered to receiver, and then copy it to some MySQL/MongoDB/Riak/WhateverDB you like.
How is that sounds to you?
