const redis = require('redis');

port: 19606,
password: 'password'
});
client.on('ready', () => {
console.log('redis is connected');

client.on('error', (err) => {

This somehow does not seem to work. What am I doing wrong? It keeps connecting to 127.0.0.1:6379 which is the default config instead of what I am passing. This is only happening with nodejs client of redis. go-redis the golang client for redis is working flawlessly.
Just a guess, but which Node Redis version do you use? I had difficulties upgrading myself. The configuration of the client has changed since version 4.x.x. Since version 4.x.x you have to use a confiuration according to Client Configuration. Therefore use
const client = redis.createClient({
socket: {
host: 'redis-19606.redislabs.com',
port: 19606,
}
});
or use a URL
const client = redis.createClient({
url: "redis://redis-19606.redislabs.com:19606"
});
Your client configuration matches the Node Redis version 3.x.x but not 4.x.x. Please see Redis NPM v3.1.2 and Redis NPM v4.0.1 for details.
you should maintain this format of Redis connecting string:
redis://:YOUR_PASSWORD@YOUR_ENDPOINT:YOUR_PORT
redisClient.on("connect", () => {})
and then you can use redisClient variable to get and set values.
