Connect with NodeJS

This example connects to Redis service from NodeJS, making use of the ioredis library.

Variables

These are the placeholders you will need to replace in the code sample:

Variable

Description

REDIS_URI

URL for the Redis connection, from the service overview page

Pre-requisites

Install the ioredis library:

npm install --save ioredis

Code

Create a new file named index.js, add the following content and replace the placeholder with the Redis URI:

const Redis = require("ioredis");
const redisUri = "REDIS_URI"
const redis = new Redis(redisUri);

redis.set("key", "hello world");

redis.get("key").then(function (result) {
    console.log(`The value of key is: ${result}`);
    redis.disconnect();
});

This code creates a key named key with the value hello world and no expiration time. Then, it gets the key back from Redis and prints its value.

Run the code:

node index.js

If the script runs successfully, the outputs should be:

The value of key is: hello world
