}

async function useWithoutEnvVarSet() {
  const url = "redis://localhost:6379";
  return await getRedisClient(url); // if env variables are not set
}

The package also supports a Koa middleware to attach the client to ctx.

import { getRedisClient, getRedisClientMw } from "@awsmag/power-ec-redis";
import Koa from "koa";

const server = new Koa();
const url = "redis://localhost:6379";
(async () => {
  await getRedisClient(url);
  server.use(getRedisClientMw());

  // rest of your code goes here
})();

// it will be available as `redisClient` in ctx. In your handler use it like below.

// perform functions using redisClient
const redisClient = ctx.redisClient;
