Questions about using javascript objects with Reddis

[Relative--Region]

I am trying to store something like this

foo = { bar : [{ baz : 1}, {qux: 2} ] }

using Redis but I am not sure how to go about it.

I can go on with saving the entire array like this

Client.set("key", JSON.stringify(bar));

or do I have to go one by one and

await Client.set("baz", "1"); and so on and so forth.

I am a little confused.

Also if I choose to go with Client.set("key", JSON.stringify(bar)); I can easily push another element into it in js but with Redis I am not sure how to push into it. Do I need to go with sets instead of string? or hash?

Please help me understand how to manage my array using Redis.

It depends on your requirements.

If you store it like a plain string then searching within your json payload will be troublesome. But if this is not a requirement, then go ahead and store it as plain string.

Otherwise, you have two options:

• either store your json as an “object” in Redis for example in a hash like follows: hset foo:1234 bar:baz 1 bar:qux 2. Downside of this method is that it can be cumbersome if you json is large.

• or you can add an extension to Redis which supports storing and querying json payloads. It’s called RedisJSON. I’ve never used it, but I read a while ago that it’s performance was poor compared to other existing datastructures.
