## AWS Serverless Airline Booking



Serverless Airline Booking is a complete web application that provides Flight Search, Payment, Booking and Loyalty points including end-to-end testing, GraphQL and CI/CD. This web application was the theme of Build on Serverless Season 2 on AWS Twitch running from April 24th until August 7th - Check out [Twitch branch for the list of 14 episodes](https://github.com/aws-samples/aws-serverless-airline-booking/tree/twitch).



For more up-to-date information on what's being implemented, take a look at our current [Boards](https://github.com/aws-samples/aws-serverless-airline-booking/projects).

## Deployment

## Stack



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.
