Client.expire(key, seconds)

Sets a timeout on key, after which the key will automatically be deleted. Note that calling Expire with a non-positive timeout will result in the key being deleted rather than expired.

Parameters

Parameter	Type	Description
`key`	string	the key to set the expiration of.
`seconds`	number	the value in seconds to set the expiration to.

Returns

Type	Resolves with	Rejected when
`Promise<boolean>`	On success, the promise resolves with `true` if the timeout was set, and `false` if the timeout wasn’t set.

Example

import redis from 'k6/experimental/redis';

// Instantiate a new redis client
const redisClient = new redis.Client('redis://localhost:6379');

export default async function () {
  await redisClient.set('mykey', 'myvalue', 10);
  await redisClient.expire('mykey', 100);

  const ttl = await redisClient.ttl('mykey');
  if (ttl <= 10 || ttl >= 100) {
    throw new Error('mykey should have a ttl of 10 <= x < 100');
  }
}
