Coding Challenge - AWS Deployment with CDK

Welcome to the Coding Challenge! This project demonstrates the deployment of a full-stack application on AWS using AWS Cloud Development Kit (CDK) and CloudFormation. The stack includes the following AWS resources:

• AWS Lambda Function
• Amazon S3 Bucket
• Amazon API Gateway
• Amazon DynamoDB Table

Prerequisites

Before you begin, ensure you have the following installed:

• AWS CLI
• AWS CDK
• Node.js
• npm

Set AWS Account and Region

Configure your AWS account and region by setting the necessary environment variables.

On Windows (CMD)

set CDK_DEFAULT_ACCOUNT=your-account-id
set CDK_DEFAULT_REGION=your-region
set AWS_REGION=your-region
set AWS_DEFAULT_REGION=your-region
set AWS_ACCESS_KEY_ID=your-access-key-id
set AWS_SECRET_ACCESS_KEY=your-access-key-secret

On macOS/Linux

export CDK_DEFAULT_ACCOUNT=your-account-id
export CDK_DEFAULT_REGION=your-region
export AWS_REGION=your-region
export AWS_DEFAULT_REGION=your-region
export AWS_ACCESS_KEY_ID=your-access-key-id
export AWS_SECRET_ACCESS_KEY=your-access-key-secret

Steps to Run

1. Install AWS CLI

   Install the AWS CLI by following the instructions here.

2. Configure AWS CLI

   Run the following command and follow the prompts to configure your AWS CLI with your credentials:

   aws configure

3. Install AWS CDK

   Install the AWS CDK globally using npm:

   npm install -g aws-cdk

4. Clone the Repository

   Clone this repository to your local machine and navigate into the project directory:

   git clone https://github.com/Devansh-ops/aws-cdk-demo-project.git
   cd aws-cdk-demo-project

5. Set Environment Variables

   Export or set the environment variables as shown in the previous section.

6. Deploy the Stack

   Deploy the stack to AWS. This command will also install npm packages and create the necessary configuration:

   npm run deploy

7. Run the Frontend

   Navigate to the frontend directory and start the development server:

   cd file-upload
   npm start

8. Access the Application

   Open your web browser and navigate to http://localhost:3000 to access the application.

Project Structure

The project is organized as follows:

• infrastructure: Contains the CDK stack definitions and resource configurations.
• lambda: Contains the source code for the Lambda function.
• file-upload: The React frontend application.

Key Features

• AWS Lambda: Handles backend logic and interacts with DynamoDB.
• Amazon S3: Stores uploaded files securely.
• Amazon API Gateway: Provides a RESTful API to interact with the Lambda function.
• Amazon DynamoDB: Stores metadata and application data.
