IBM Fundamentals: Get Started Node

From Zero to Node: A Deep Dive into IBM's "Get Started Node" Service

The digital landscape is shifting. Businesses aren't just using software; they are software. This transformation is fueled by cloud-native applications, microservices, and a relentless demand for faster innovation. But building and deploying these applications can be complex, especially when considering security, scalability, and the ever-present need to reduce operational overhead. According to a recent IBM study, companies that fully embrace hybrid cloud and AI see a 2.5x increase in revenue growth compared to those who don’t. Furthermore, the rise of zero-trust security models and hybrid identity solutions demands robust and easily manageable infrastructure. IBM understands these challenges, and that’s where “Get Started Node” comes in. It’s designed to dramatically simplify the process of getting a Node.js application up and running in the cloud, allowing developers to focus on what they do best: building great software. This post will provide a comprehensive guide to this powerful service, from its core concepts to practical implementation and beyond.

Hands-On: Step-by-Step Tutorial

Let's deploy a simple "Hello World" Node.js application using the IBM Cloud CLI.

Prerequisites:

• IBM Cloud account
• IBM Cloud CLI installed and configured (https://cloud.ibm.com/docs/cli?topic=cli-install-configure)

Steps:

1. Login to IBM Cloud: ibmcloud login
2. Create a resource group (if you don't have one): ibmcloud resource group create my-resource-group
3. Create a "Get Started Node" instance: ibmcloud dev get-started node create --resource-group my-resource-group --name my-node-app
4. Get the application URL: ibmcloud dev get-started node get-url --resource-group my-resource-group --name my-node-app
5. Create a package.json file:

   {
     "name": "hello-world",
     "version": "1.0.0",
     "description": "A simple Hello World Node.js app",
     "main": "app.js",
     "scripts": {
       "start": "node app.js"
     },
     "dependencies": {}
   }

1. Create an app.js file:

   const http = require('http');

   const hostname = '0.0.0.0';
   const port = process.env.PORT || 3000;

   const server = http.createServer((req, res) => {
     res.statusCode = 200;
     res.setHeader('Content-Type', 'text/plain');
     res.end('Hello World!\n');
   });

   server.listen(port, hostname, () => {
     console.log(`Server running at http://${hostname}:${port}/`);
   });

1. Deploy the application: ibmcloud dev get-started node deploy --resource-group my-resource-group --name my-node-app --directory .

Now, open the URL obtained in step 4 in your browser. You should see "Hello World!".
