🏃‍♂️ Local Development

Prerequisites

• Node.js (v18+)
• AWS CLI (Configured)
• AWS SAM CLI

1. Backend Setup

cd backend
npm install
npm run dev
# Server runs on http://localhost:3001

2. Frontend Setup

cd frontend
npm install
npm run dev
# App runs on http://localhost:5173

☁️ AWS Deployment Guide

This project follows a fully serverless architecture within the AWS Free Tier.

1. Backend Deployment (AWS SAM)

The backend uses AWS SAM to deploy Lambda, API Gateway, and DynamoDB.

cd backend
sam build
sam deploy --guided

Resources Created:

• 4 Lambda Functions (Restaurants, Menu, Orders, Users)
• 4 DynamoDB Tables
• 1 API Gateway

2. Frontend Deployment (S3 + CloudFront)

The frontend is hosted on S3 and distributed via CloudFront.

Manual Deployment:

cd frontend
npm run build
aws s3 sync dist/ s3://YOUR-BUCKET-NAME --delete
aws cloudfront create-invalidation --distribution-id YOUR-DIST-ID --paths "/*"

3. CI/CD Pipeline (Automated)

An AWS CodePipeline is configured to automatically deploy frontend changes from GitHub.

• Source: GitHub (main branch)
• Build: AWS CodeBuild (using buildspec.yml)
• Deploy: S3 Sync + CloudFront Invalidation

🔐 Credentials (Demo)

• Admin: admin@fooddelivery.com
• User: demo@example.com
