Redis connection error while connecting to Node js

Question

I am trying to connect the node js container with the Redis container, I am facing an issue when I run the node-js container and try to connect Redis. I tried most of the solutions from the web, still not able to fix the connection refused issuer.

> Node js creating the Redis client: below code works locally good, without the container.

const redis = require('redis')
const redisClient = redis.createClient({
  host: "127.0.0.1",
  port: "6379"
})

> running Redis from the latest image.

docker run -d --name redis -p 6379:6379 redis

> Error:

[nodemon] starting `node index.js`

events.js:377

      throw er; // Unhandled 'error' event

      ^
