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
