How can i connect to a Redis db that has username and password?
below is the code example i'm trying to use, ( i'm using nodejs with node-redis and Redis version "redis": "^3.0.0",)
const client = redis.createClient({
host: "localhost",
port: 6379,
password: "1234",
username: "username"
});
Depends on the version of Node Redis that you are using. Since it looks like you are using Node Redis 3.x it would look like this:
const client = redis.createClient({
host: "localhost",
port: 6379,
password: "1234",
user: "username"
});
You could also connect using a connection string:
const client = redis.createClient("redis://username:1234@localhost:6379");
Full documentation for 3.x is available on the tagged branch in the GitHub repo for Node Redis.
That said, I would recommend using Node Redis 4.x as it supports Promises, newer Redis commands, and many common Redis modules like RedisJSON and RediSearch.
To connect using 4.x:
const client = redis.createClient({
socket: {
host: "localhost",
port: 6379
}
password: "1234",
username: "username"
});
or:
const client = redis.createClient({ url: "redis://username:1234@localhost:6379" });
Details on connecting using Node Redis 4.x can be found in the README on the main branch of Node Redis and in the Client Configuration Guide.
client.quit() when I want to close a connection as it lets Redis know to dispose of the connection and closes it locally. I've run into problems when I just call client.close() where Redis doesn't know the connection is dead, and then I run out of connections. That said, for a Node.js app, I usually just keep one connection open, use it for everything, and call client.quit() when the process ends.To connect Nodejs Project with Redis Version ^4.x:
const redisClient = redis.createClient({
socket: {
host: "localhost",
port: 6379
}
password: "1234",
username: "username"
});
redisClient.on("error", (error) => console.error(`Error : ${error}`));
redisClient.connect();If you don't Provide socket, password or username then by default it will connection on 127.0.0.1:6379
for by Default Connection use Beloved mention code
const redisClient = redis.createClient();
redisClient.on("error", (error) => console.error(`Error : ${error}`));
redisClient.connect();Redis Installation in system https://redis.io/docs/getting-started/installation/install-redis-on-windows/
