Node.js and Redis Auth

Question

I dont get the redis node.js documentation for using redis auth.

per the example:

var redis = require("redis"),
client = redis.createClient();

// This command is magical. Client stashes the password and will issue on every connect.
client.auth("somepass");

In my code I have the following:

var redis = require("redis");
r = redis.createClient(6379,'xxx.xxx.xxx.xxx');
r.auth("yyyyyyyy");

app.get('/', function(req, res){
r.set("foo", 'bar');
res.writeHead(200, {'Content-Type': 'image/gif'});
res.end('Hello');
 });

Here is the error I get:

    Express server listening on port 8070 in development mode

So, what is the proper way to auth?

Answer 1

The following code creates a connection to Redis using node package redis.

const redis = require('redis');

const client = redis.createClient({
    host: '<hostname>',
    port: <port>,
    password: '<password>'
});
