const key = 'sess-test'
const uid = 1
const ttl = 60 * 60 * 24 * 30
client.set(key, uid, ttl)

Please check the readme. You have to add ‘EX’ or ‘PX’ depending on what type of timeout you want.

@atuttle That’s not quite right. Node_redis just relays the commands to Redis. What you’re wanting to do is this for inline setting of the TTL client.set(key, value,'EX', ttl, callback), as per the SET command’s documentation.

Additionally, the client.ttl() command gets the time to live not sets it. If you want to do it set the TTL you have to use client.expire().
