This is a ticket application for selling concert tickets to the public, organized by SoundWave Productions. The repository contains two folders: front-end and service. The front-end folder contains the source code for the web application, while the service folder contains the source code for the backend API, which is implemented using a serverless architecture.
Ticketing System uses a number of technology stack to work properly:
- node.js - Runtime for the lambda function
- Vue - Progressive, incrementally-adoptable JavaScript framework
- Vite - Fast and modern bundler for building frontend apps.
- Vuetify - Material Design for Vue
- dynamodb - Fast, flexible NoSQL database service for single-digit millisecond performance at any scale by AWS
- PostgresQL - Powerful, open-source, relational database.
- S3 - Scalable, durable, secure object storage
The root folder for Front-End projects is front-end.
VITE_BASE_API_URL=YOUR_API_ENDPOINT
VITE_WEBSOCKET_URL=YOU_WEBSOCKET_ENDPOINT
VITE_API_TOKEN=YOUR_AUTH_TOKEN
VITE_DEVICE_ID=YOUR_AUTH_DEVICEIDnpm installnpm run devnpm run buildThe root folder for backend projects is service.
All dependencies required by each Lambda function are located in the service/layer folder and are bundled into a layer with name lks-layer, dont forget to attach the layer into lambda function.

The websocket in this project is used to provide asynchronous responses to the front-end when messages on SQS have been successfully processed by the lambda consumer. The websocket has six routes: $connect, $disconnect, $default, sendMessage, getConnectionId, and broadcastMessage. The route selection expression for each route is $request.body.action. Each route invokes the lambda function that contains the websocket.js file. Don’t forget to use prod stage as a production stage name.
