So, you want to build a car rental web app? Forget taxis, Uber, or borrowing your cousin’s Maruti 800. Let’s create something cooler using the power of AWS! In this guide, I’ll walk you through building Easy Ride, a fully functional car rental app.
Project Overview
This project was inspired by Amber Israelsen’s WildRydes, and I customized it to enhance my skills. With Easy Ride, users can browse, book, and ride cars seamlessly.
AWS Services Used + Git hub
Amplify: Hosting static files (HTML, CSS, JS).
Cognito: User authentication and management.
API Gateway: Interface for frontend-backend communication.
Lambda: Booking and business logic.
DynamoDB: NoSQL database for ride data storage.
Step 2: Add User Authentication
- Navigate to Amazon Cognito and create a new User Pool (e.g., EasyRideUserPool).
- Copy the User Pool ID and App Client ID, and update these values in your app’s config.js.
- Test the authentication flow by signing up and signing in on the live app.
Step 4: Backend Logic with AWS Lambda
- Create a Lambda function with the runtime Node.js 16.x.
- Attach an IAM role with DynamoDBWriteAccess to enable data storage.
- Write the booking logic in index.js, and ensure the table name matches your DynamoDB setup.
Step 5: API Gateway Integration
- Create an API in Amazon API Gateway.
- Add a POST method linked to your Lambda function for booking rides.
- Configure Cognito as the authorizer for secure access.
Step 7: Clean Up
To avoid unnecessary costs, delete unused resources like:
- Cognito User Pool.
- DynamoDB table.
- Lambda functions and API Gateway resources.
- Amplify app deployment.
Conclusion
Congratulations! You’ve successfully built a car rental web app using AWS services. This project covers the full stack—from hosting with Amplify to backend logic with Lambda and secure data storage with DynamoDB.
