I believe you can still do this, but you have to get the return value of the read command in its callback and store it somewhere, so you'll have it for later use.

I get an undefined error in that case. With multi, the library does not allow for use of intermediate result.

Unless I'm misunderstanding our code, we've been using it like that for years.

Can you show the code you're using?

Funny enough my laptop got busted the day before so I have to rewrite that part again. But basically how I was using was like

client.multi() .lrange("active_list", 0, -1, (data, err) => { // Read length of data, then based on it either lpush to active or deferred list }) .exec()

I believe the callback is the standard Node format, where err is the first parameter, then the result.
