Do you have a fridge at work or in a club, selling stuff for internal use? This is intended to be a simple program which can be used to facilitate this.

I'm doing this with very limited time as a small project to learn some Golang amoung others, so it might take a while before anything comes up here, if ever ;)

• With account it should be very quick to choose an item
• No checkout-procedure - you can revert transactions instead
• No login = simply display price to pay (large)

• Use oauth2 for users. Integrate with auth0?
• Leverage AWS Lambda & Dynamodb and use static web page since it will be low & irregular traffic
• Continue!

• S3 & CloudFront to serve static page
  • jQuery to on client side fetch dynamic data like products
• Use AWS cognito to authenticate users
• API Gateway backed by AWS Cognito user pool as authorizer
• Lambdas to handle requests
• DynamoDb to handle inventory & transactions

@startuml

cloud "AWS" {
  API - [Cogniton]
  
  database "S3" {
    [Static site]
  }
  Cloudfront -- [Static site]
  [Static site] -up-> API

  node "Lambdas" {
    [PerformTransaction]
    [GetTransactions]
  
  }
  API -down-> [PerformTransaction]
  API -down-> [GetTransactions]

  [GetTransactions] -down-> DynamoDb
  [PerformTransaction] -down-> DynamoDb

  database "DynamoDb" {

  }
}
