Connect with NodeJS

This example demonstrates how to connect to Dragonfly® from NodeJS using the ioredis library, which is officially supported and compatible with Dragonfly. For more information, see Dragonfly SDKs.

Variables​

Replace the following placeholders in the code sample with the appropriate values:

VariableDescription
DRAGONFLY_URIURL for the Dragonfly connection

Prerequisites​

Install the ioredis library:

npm install --save ioredis

Code​

Create a file named index.js, add the following content and replace the DRAGONFLY_URI placeholder with your Dragonfly instance's connection URI:

const Redis = require('ioredis');

const redis = new Redis('DRAGONFLY_URI'); // Replace with your Dragonfly URI

redis.set('key', 'hello world').then(() => {
     return redis.get('key');
}).then((value) => {
     console.log('The value of key is:', value);
     process.exit();
}).catch((err) => {
     console.error('Error:', err);
     process.exit(1);
});

This code connects to Dragonfly, sets a key named key with the value hello world (without expiration), then retrieves and prints the value of this key.

Run the code​

To execute the code, use the following command in your terminal:

node index.js

If everything is set up correctly, the output should be:

The value of key is: hello world
