node_redis - how to get the TTL for a key?

Project page: https://github.com/NodeRedis/node_redis

It's possible to set an expiration for a key with: 

client.set('key', 'value!', 'EX', 10);

Is there a way to get (read) the expiration of am existing key?

You can use ttl function to get the remaining time until a key is expired. Note that you should promisify the function or use callbacks to get the result. An example code block in an async function would be like this:

const { promisify } = require('util');
const ttl = promisify(client.ttl).bind(client);
client.set('key', 'value!', 'EX', 10);
const remaingTime = await ttl('key');
