BiteTut - Headless Serverless E-commerce POC

BiteTut is a serverless e-commerce storefront that provides subscription-based online learning content managed by headless CMS.

Features

• Create, manage and publish content with Contentful
• Manage recurring payments using Stripe
• Secure user authentication and access control using AWS Cognito
• Highly customizable components with full theming support using styled-components
• Deploy and manage AWS infrastructure to use AWS Lambda functions with the Serverless Framework

Overview

This project consists of a ReactJS front-end and a serverless back-end using AWS Lambda. The following AWS services are also used in this project:

• S3: a public S3 bucket to host the React web app and a private S3 bucket to store private content
• Simple Email Service (SES): notify customers with the pre-sign URL of the private content
• Cognito: user sign-in and access control
• Simple Notification Service (SNS): save user information to DynamoDB when a user is created in the Cognito user pool
• DynamoDB: store user account information (e.g. user email and their Stripe customer ID)
