Technique stacks

Backend

1. use Node Express (Typescript) to build backend API server (GraphQL/Rest)
2. use MongoDB (Altas online) as DB, use **Mongoose**as ORM to build data model to connect MongoDB (under /src/models/**)
3. use apollo-server-express to build GraphQL server
   1. Schema: /src/graphql/schema/**
   2. Resolvers: /src/graphql/resolvers/**
   3. Separated different modules into different files ( like reservation.resolvers.ts)
4. Implemented basic authentication as sample (rest and graphql, not integrated with frontend)
   1. RestAPI: under src/rest
5. use Jest to do unit tests (src/test/**)
6. use winston as Logging (/src/utils/logger.ts)
7. wrapped AppError and errorHandler as global error handler under /utils/errorHandler.ts
8. TODO: Consider IoC to inject services and db repo for future enhancement

Frontend

1. React
3. @apollo/client to connect GraphQL API
