non-static ReplyTransformer?

[Jonahss]

Hi,

I'm the author of ioredisgraph, which just wraps ioredis, adds a new parameter to the constructor, and sets a custom ReplyTransformer.

Is there a way to set different ReplyTransformers for different instances of the client? The way that redisgraph works, my ReplyTransformer needs to behave differently depending on which db is being accessed.

One possible way is to override the instance method directly:

const asCallback = require('standard-as-callback').default
const Redis = require('ioredis')

const redis = new Redis()
const { mset } = redis
redis.mset = function (...args) {
  const callback = typeof args[args.length - 1] === 'function' ? args.pop() : null
  return asCallback(mset(...args).then(transformer), callback)
}

Haven't tested the code though. 🤣

Oh okay, that should work fine. I'll just override the redis.call method.

Thanks!
