Serverless Notes App

A modern serverless full-stack notes application with a clean frontend and a scalable AWS backend. Designed with best practices for infrastructure-as-code, cloud services, and API-driven development.

🚀 Features

• Create, Read, Update, Delete (CRUD) notes seamlessly.
• Serverless backend with AWS Lambda for compute and DynamoDB for data storage.
• API Gateway to expose REST endpoints.
• Frontend built with HTML, CSS, and JavaScript.
• Infrastructure as Code (IaC) using Terraform for reproducible and automated deployments.
• CORS-enabled API integration for frontend-backend communication.
• UUID-based unique note identifiers for reliable data management.

⚙️ Tech Stack

• Frontend: HTML, CSS, JavaScript
• Backend: AWS Lambda (Node.js 18.x)
• Database: AWS DynamoDB
• API: AWS API Gateway
• Infrastructure: Terraform
• ID Generation: UUID

💻 Setup & Deployment

Prerequisites

• AWS CLI configured with credentials
• Terraform installed
• Node.js and npm installed

Steps

1. Clone the repository

   git clone https://github.com/ch-rahulmachra/Terraform-Project01-Notes-App.git
   

2. Install dependencies for Lambda functions cd build/createNote && npm install cd ../updateNote && npm install cd ../getNote && npm install cd ../deleteNote && npm install

3. Zip Lambda functions for dir in createNote updateNote getNote deleteNote; do cd build/$dir zip -r index.zip . cd ../../ done

4. Deploy infrastructure using Terraform terraform init terraform plan terraform apply

5. Serve frontend Open modules/frontend/index.html in a browser or host it on S3.

🔗 API Endpoints

Method Endpoint Description POST /create Create a new note POST /get Fetch a note by ID POST /update Update a note by ID POST /delete Delete a note by ID

Note: All endpoints are CORS-enabled for frontend access.

📈 Why this Project Stands Out

•	Full serverless architecture: minimal maintenance, auto-scaling backend.
•	Terraform IaC ensures reproducible deployments and professionalism.
•	Demonstrates API integration and frontend-backend interaction.
•	Implements best practices for AWS IAM roles, permissions, and Lambda functions.

📝 Future Improvements

•	User authentication with AWS Cognito
•	Rich text editor for notes
•	Tagging and search functionality
•	Frontend hosted on S3 with CloudFront
