Accessing Azure Managed Instance for Apache Cassandra using Node.js

Azure Managed Instance for Apache Cassandra provides automated deployment and scaling operations for managed open-source Apache Cassandra datacenters. It accelerates hybrid scenarios and reduces ongoing maintenance.

This quick start demonstrates how to connect to a Cassandra Managed instance cluster with Node.js. You'll then build a user profile console app, output as shown in the following image, with sample data.

Running this sample

• Before you can run this sample, you must have the following pre-requisites:
  • An Azure Managed Instance for Apache Cassandra cluster. Check out our Quickstart guide here.
  • Networking access from this application to your Azure Managed Instance for Apache Cassandra cluster (the service only deploys private IP addresses injected into a Virtual network).
  • Node.js version v0.10.29 or higher.
  • Git.
  • Node.js driver for apache cassandra // to install the driver - run npm install cassandra-driver.

1. Clone this repository:

   git clone git@github.com:Azure-Samples/Azure-Samples/azure-cassandra-mi-node-getting-started.git cassandrami

2. Change directories to the repo:

   cd cassandrami

3. Install npm dependencies:

   npm install

4. Next, substitute the contactPoint, username, password, and localDataCenter values in config.js with your corresponding Azure Managed Instance for Apache Cassandra values.

   module.exports = {
           username: "Cassandra cluster username",
           password: "Cassandra cluster password",
           contactPoint: "I.P. address of a node in your cluster",
           keySpace: "uprofile",
           localDataCenter: "datacenter-1"
   };

5. Run uprofile.js in a terminal to start your start your node application:

   npm start

About the code

The code included in this sample is intended to get you quickly started with a Node.js console application that connects to Azure Managed Instance for Apache Cassandra.
