You can also use Blue Bird Library plus monkey patching will do the trick for you. For example:

const bluebird = require('bluebird')
const redis = require('redis')
async connectToRedis() {
     // use your url to connect to redis
     const url = '//localhost:6379'
     const client = await redis.createClient({
                url: this.url
            }) 
     client.get = bluebird.promisify(client.get).bind(client);
     return client
   }
// To connect to redis server and getting the key from redis
connectToRedis().then(client => client.get(/* Your Key */)).then(console.log)
