Introduction

Building and deploying serverless applications can be an exhilarating experience. In this comprehensive guide, we'll walk through the process of creating an EC2 instance, installing Node.js and npm, creating a new serverless project, setting up AWS credentials, and deploying a serverless application. Additionally, we'll explore testing, monitoring, and the powerful world of CI/CD (Continuous Integration/Continuous Deployment). Let's dive right in! ๐Ÿ› ๏ธ๐Ÿ‘จโ€๐Ÿ’ป

Prerequisites

Before we start, ensure you have the following prerequisites:

๐Ÿ”ง EC2 Instance:

  • Access to an AWS EC2 instance to run your serverless project.

๐Ÿ“ฆ Node.js and npm:

  • Install Node.js version 20 and npm version 10 on your EC2 instance.

๐Ÿ’ผ Serverless Framework:

  • Install the Serverless Framework globally: npm install -g serverless.

๐Ÿ”‘ AWS Credentials:

  • AWS access and secret keys with admin access to connect with your AWS account.

๐Ÿ” Authentication Access:

  • Be prepared to provide authentication access by typing "yes" when prompted.

Creating a Serverless Project

  • The architecture of the project:

Now that we have our prerequisites sorted, let's create a serverless project:

  1. Project Setup:

    • Start by creating a new serverless project using serverless create.

    • Provide the project name and application name as per your preference.

  2. AWS Configuration:

    • Configure your AWS access and secret key when prompted.
  3. Authentication:

    • Grant access by typing "yes" when asked.

Building the Serverless Application

We've laid the foundation; now, let's build the architecture of our serverless application:

๐Ÿ—๏ธ Project Architecture:

  1. Project Cloning:

  2. Change Directory:

    • Navigate to the project directory using cd aws-node-http-api-project.
  3. Branch Selection:

    • Switch to the 'dev' branch using git checkout dev.

  4. Serverless Configuration:

    • Create a new project on the Serverless Framework website. Use serverless --org=iamsuman007 to connect with your serverless.yaml file.

    • Ensure that the application name matches the one defined in your serverless.yaml file.

  5. Automatic Service Creation:

    • The framework will automatically create all the necessary services to run your application.
  6. Accessing the Application:

Testing and Data Validation

With your serverless application deployed, it's time to test and validate its functionality:

๐Ÿงช Testing and Validation:

  1. Data Insertion:

  2. Data Validation:

    • Confirm that the data is available inside the DynamoDB table.
  3. Adding More Data:

CI/CD Pipeline

To streamline your development process and ensure smooth deployments, set up a CI/CD pipeline:

๐Ÿ”„ CI/CD Pipeline:

  1. Pipeline Creation:

    • Create a CI/CD pipeline for your serverless application.
  2. Deployment:

    • Ensure that your CI/CD pipeline is working seamlessly and successfully deploying changes.

Conclusion

Building a serverless Node.js application on AWS with an EC2 instance and implementing CI/CD can be a rewarding experience. With the right setup and tools, you can create, deploy, and maintain powerful serverless applications with ease. ๐ŸŒŸ

Now that you've mastered these steps, you're well-equipped to embark on your serverless journey. Happy coding and deploying! ๐Ÿ’ป๐Ÿš€๐Ÿ” Checkout GitHub Repository for projects:
