calling SET removes the TTL of a record

I am not sure if this is intentional, if there is a way to change it but the document of ioredis just sucks or is something not really possible with this module.

I created some record like

await client.setex('key1', 'hello', 10);
const x = await client.ttl('key1')
// x = 10

when the code is changed to the following

await client.setex('key1', 'hello', 10);
await client.set('key1', 'world');
const x = await client.ttl('key1')
// x = -1

just running a set command automatically removes TTL. Now I have tried looking at the types (d.ts) file for anything that I can use and there appears to be something called an “expiryMode” parameter in the set command. looking at possible values for this and wow… ioredis docs denies its existence. It has no default and enumerated values, not even docummented. so what is that for? what I am doing btw is try to update the record without altering the existing TTL value

ugh! nevermind! you guys should use enums for this on your Typescript…

EX seconds – Set the specified expire time, in seconds. PX milliseconds – Set the specified expire time, in milliseconds. NX – Only set the key if it does not already exist. XX – Only set the key if it already exist. KEEPTTL – Retain the time to live associated with the key
