How does one connect to an Upstash Redis database programmatically?

[maxime1]

The Upstash dashboard provides an example to connect to my Redis instance using a connection string:

const Redis = require("ioredis");

// Using *** to mask my credentials
let client = new Redis("redis://:***@fly-***.upstash.io:6379");
client.set('foo', 'bar');

However, this does not work (unable to connect).

Apparently, you need to use the IPV6 address to connect to the instance.

So I tried multiple combinations of x.internal and specifying the family to 6, but still no success.

What’s the actual connection string I should use to connect to my Redis instance? Is there anything particular I need to do beforehand?

Thanks for the guidance

We just set this up with ioredis. Make sure to:

• Connect with IPv6 (you already mentioned this)
• Connect from within the Fly network. This is automatic from any Fly app, but in development you’ll need to activate a Wireguard tunnel on your machine or use the fly proxy command.

const Redis = require("ioredis");
const client = new Redis(
  "redis://default:xxxxx@fly-xxxxx.upstash.io:6379",
  { family: 6 }
);

Thanks for the reply Elliot

Connect with IPv6 (you already mentioned this)

How does one do that? Is simply passing in the family: 6 option enough? Do I need to use some sort of .internal address, or can I simply use the upstash.io url?

Using the family: 6 option with the Upstash URL works great. Thanks
