To get started with the Serverless Airline application, you can deploy into your AWS Account by following our Get Started instructions
Summary of what the stack looks like now including a picture with the core tech:
- Front-end - Vue.js as the core framework, Quasar for UI, Amplify for Auth UI component and AWS integration, and Stripe JS with Stripe Elements for card tokenization, validation, etc.
- Data - All data is modeled after GraphQL types and stored in DynamoDB. Python being the core language for all services except Loyalty that's written in Typescript, and JavaScript for front-end.
- API - GraphQL is managed by AppSync and also acts as an API Hub to interact with other services. Loyalty implements a REST API to demonstrate how to secure service-to-service communication while maintaining a public endpoint. Payment API is also based on REST to demonstrate an external payment provider.
- Auth - Cognito provides JSON Web Tokens (JWT) and along with AppSync fine-grained authorization on what data types users can access.
- Messaging - Booking workflow is managed by Step Functions while SNS provides service-to-service communication through messaging between Booking and Loyalty.
