feat: ioredis cache handler

[jsmylnycky]

The primary projects I work on leverage ioredis as the client of choice, primarily due to a history of having better results connecting to AWS ElastiCache.

The goal here was to copy the redis-strings cache handler, and update the calls to the ioredis variation.

I'm sharing this back in hopes that others might find this particular client useful.

I confirmed all e2e tests pass.

I considered explicitly calling this ioredis-strings but opted for shorthand ioredis. I'm happy to change it if anyone feels strongly, just let me know!

Hi @jsmylnycky!

Thank you for your contribution to the @neshca/cache-handler!

It seems like the Redis team has dropped the support of the ioredis package half a year ago. They claim that node-redis V5 is their main focus. Maybe instead of adding this Handler we'll create a place for community Handlers. It can be a new package in a monorepo, wiki or docs page. What do you think about it?

Hi @better-salmon ! Thanks for sharing that info about ioredis. Admittedly, that revelation will push me to look deeper into using node-redis with Elasticache and just work through the hurdles I ran into last time I tried (been a couple years).

If you still want to proceed with a community handlers package, I'm happy to push this into that instead, in case it may help someone who can't quite as easily move away from ioredis.

Just let me know how you'd look to proceed with this!

[better-salmon]

For now supporting Next.js 15 is top priority. I'll return to you later 🙂

[jsmylnycky]

@better-salmon 100% understood and agree on the Next15 priority!

Just wanted to let you know that I would like to go ahead with publishing this as a community handlers package, so I'll work with you when you're ready to put some time into that.

I spent a good amount of hours last week trying to get node-redis to work, but unfortunately it still doesn't play very nice with ElastiCache. Their Cluster support is pretty lacking of certain features (isReady doesn't exist, and isOpen is too broad), and their published events only seem to work for error and nothing else, so it's extremely clunky trying to determine if the client is actually active and connected or not. I'll give it another look with v5, but I haven't seen a published timeline to know when that will be released.

This is awesome @jsmylnycky , we indeed need this cause unfortunately node-redis lacks a lot of things. For example sentinel support (i know they are working on it but its still not added) which we for example rely on. I started to write my own solution but thankfully i stumbled upon this code which is a great help. A big 👍 from me to support the PR merge !

[jsmylnycky]

I'll get the conflicts resolved once I get the green light on how to proceed :) Just giving this project some breathing room while they focus on Next15 support.

[gergokee]

Yeah i see suport for nextjs15 is still in progress so we are not upgrading to 14 until we see it's safe. thank you anyways ! :)

ps.: hope node-redis will also add/fix their cluster and sentinel support by then
