📦 Cloud Based Inventory Management System

A full-stack cloud-native inventory management system built using AWS Serverless Backend and a modern frontend dashboard UI. This project demonstrates hands-on skills in Lambda, API Gateway, DynamoDB, Serverless Framework, and Web Development.

---

🚀 Project Overview

This system enables users to add, edit, update, delete, and view inventory items in real time using a fully serverless backend.

It includes:

• Frontend: Inventory Dashboard (HTML/CSS/JS)
• Backend: AWS Lambda + API Gateway + DynamoDB
• Infrastructure: Serverless Framework (IaC)

The Backend exposes secure REST APIs while the Frontend consumes them to perform CRUD operations.

🏗️ Architecture

Frontend (Inventory Dashboard)
          |
          |  REST API Calls (GET, POST, PATCH, DELETE)
          v
    API Gateway
          |
          v
      AWS Lambda (api.js)

⚙️ Backend Setup & Deployment

1️⃣ Install Serverless Framework

npm install -g serverless

2️⃣ Install backend dependencies

cd backend/lambda
npm install

3️⃣ Configure AWS Credentials

aws configure

4️⃣ Deploy Backend

cd backend
serverless deploy

This will:

• Create DynamoDB table
• Deploy Lambda functions
• Create API Gateway endpoints
• Output REST API URLs

---

🎨 Frontend Setup

1. Open inventory-dashboard/index.html in browser
2. Update API base URL:

const apiBaseUrl = "https://YOUR_API_ID.execute-api.ap-south-1.amazonaws.com/dev";

3. Refresh the page — now the dashboard will work with your live API.
