This article is designed with you in mind - breaking down each step of the process in a simple, easy-to-understand way. This comprehensive guide will help you get your serverless application off the ground. Let's dive in and start exploring the power of cloud computing! Content Deploying a serverless Node.js application to Google Cloud involves several key steps: Set up a Google Cloud Account and a New Project Install and Configure Google Cloud SDK Write Your Node.js Code Deploy Your Function Test Your Application Set up a Google Cloud Account and a New Project Firstly, you'll need a Google Cloud account. If you don't have one already, head over to and create a free account. Once your account is set up, create a new project in the Google Cloud Console (Image 1). Google Cloud Then you should click on (image 2) and then click on (image 3) button. “My Project“ “NEW PROJECT“ On this page, you will see all existing projects that you have access to see.

Finally, you will see on the main Google Console page. “Your project name“ Install and Configure Google Cloud SDK To deploy your Node.js application, you'll need to install Google Cloud SDK. You can download it . Once installed, you need to authenticate and configure the SDK to use your Google Cloud project: here Open your terminal and run the following command to authenticate: gcloud auth login This will open a new browser window where you can log in with your Google account. Next, set your project ID with the following command (replace 'your-project-id' with the actual ID of your project): gcloud config set project your-project-id Write Your Node.js Code Writing a simple nodejs project I have detailed explained in my previous . The main project code will be: article const http = require('http');

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

server.listen(8080, '0.0.0.0', () => {
    console.log('Server running at http://0.0.0.0:8080/');
}); A package.js will be: {
  "name": "hackernoon",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
} Also, you need to create a file for gcloud and save it in the project folder. Put this code: app.yaml runtime: nodejs18
service: default now requires an active . You will need to add one, otherwise, you will not be able to deploy your nodejs app on GCP. Enable Cloud Functions, after adding billing info, your Google account will have free 300 creds on it. Cloud Functions billing account Run from the project folder and execute this command: cmd.exe gcloud app create This command will enable the App Engine on your current project. You should choose a location after the gcloud will do everything for you. Creating App Engine application in project [ivory-studio-387214] and region [europe-central2]....done.
Success! The app is now created. Please use `gcloud app deploy` to deploy your first app. Finally, execute this deploy command: gcloud app deploy --quiet app.yaml --promote --stop-previous-version --version main-v1 You will see the message that your nodejs has successfully deployed. On your console, you will see the deployed information: descriptor:                  [C:\Users\Nuriq\Desktop\Hackernoon\app.yaml]
source:                      [C:\Users\Nuriq\Desktop\Hackernoon]
target project:              [ivory-studio-387214]
target service:              [default]
target version:              [main-v1]
target url:                  [https://ivory-studio-387214.lm.r.appspot.com]
target service account:      [App Engine default service account] Now, you can access your app via target url: https://ivory-studio-387214.lm.r.appspot.com Conclusion Congratulations on taking your first steps into the world of serverless applications and Google Cloud deployment. In this guide, you've learned how to set up your Google Cloud account, install and configure Google Cloud SDK, write a Node.js function, and deploy and test it on Google Cloud.
