Redis does not provide a full async await adapter for node.js so usually as a workaround people are promisifying the lib.

const { promisify } = require('util');
const getAsync = promisify(client.get).bind(client);

async function getValue(){
    let response = await getAsync("products");
}

An other approach to promisify the entire redis library you can use:

const redis = require('redis');
bluebird.promisifyAll(redis);

Now you will be able also to use the methods using async/await.

I could not understand .how to entire redis using bluebird.promisifyAll(redis); – smith hari May 01 '19 at 11:33
To not promisify each method separately you promisify all of them at once. – Alexandru Olaru May 01 '19 at 11:37
