Connect to Redis

Using the r2d2 module, you can connect to a Redis database running anywhere.

Import the `sendCommand()` function from r2d2

import { sendCommand } from "https://deno.land/x/r2d2/mod.ts";

Create a TCP connection with the Redis server

const redisConn = await Deno.connect({ port: 6379 });

Authenticate with the server by sending the command "AUTH <username> <password>"

await sendCommand(redisConn, [
  "AUTH",
  Deno.env.get("REDIS_USERNAME")!,
  Deno.env.get("REDIS_PASSWORD")!,
]);

Set the "hello" key to have value "world" using the command "SET hello world"

await sendCommand(redisConn, ["SET", "hello", "world"]); // "OK"

Get the "hello" key using the command "GET hello"

await sendCommand(redisConn, ["GET", "hello"]); // "world"

Close the connection to the database

redisConn.close();

Run this example locally using the Deno CLI:

deno run --allow-net --allow-env https://docs.deno.com/examples/scripts/redis.ts
