Save nested hash in redis via a node.js app

Question

I\'m using node_redis and I\'d like to save a structure like:

{
users : 
    \"alex\" : { \"email\" : \"alex@gmail.com\",
           \"password\" : \"alex123         


        

Answer 1

As far as I know there isn't native support for nested structures in Redis, but they can be modeled for example with set+hash (similar to hierarchical trees). Hashes are probably best suited for storing fields and values of single JSON object. What I would do is to store each user with a prefix (which is a Redis convention), for example:

db.hmset("user:alex", JSON.stringify(jsonObj));

and then use sets to group users into one set with a key named users. I can then get all of the users keys by smembers command and access each of them individually with hgetall.
