The Gilded Rose Expands

The Gilded Rose* is a small inn in a prominent city that buys and sells only the finest items. The shopkeeper, Terry, is looking to expand by providing merchants in other cities with access to the shop's inventory via a public HTTP-accessible API. The Gilded Rose would like to utilize a surge pricing model like Uber to increase the price of each item by 10% if it has been viewed more than 10 times in an hour.

API requirements

• Retrieve the current inventory (i.e. list of items)
• View an individual Item by name
• Buy an Item
  • authentication needed

Here is the definition for an item:

class Item {
    public String name;
    public String description;
    public int price;
}

A couple questions to consider:

1. How do we know if a user is authenticated?
2. Is it always possible to buy an item?

Deliverables

• The project should run and build in your IDE, by command line, and by java -jar .
• Complete this skeleton project with the required functionality to achieve the API requested.
• Use the simple H2 in memory database that is already configured.
• A system that can process the two API requests via HTTP.
• An authentication system.
• Include unit and integration tests.
• The code should be published in a public accessible repository, so we can clone and review it.

Summary

Prepare a little summary of your application here.

• Describe and explain your surge pricing design.
• Describe your API endpoints design and model. Include one example of a request and response for each API call.
• Explain the authentication mechanism you chose, and why.
• Explain your testing, what you covered, and why.
• Describe the features you would include if this was an actual business application.

Provided Resources

• A simple Maven-managed project configuration
• Pre-configured Spring Boot Application with the basics and an in-memory DB
• Use this JDK 11 binary if you don't have one
  • Linux: tar.gz
  • MacOS: pkg or tar.gz
  • Windows: msi or zip

FAQ

• Include any project dependencies you need, i.e. lombok, apache commons
• The surge price mechanism is open-ended. Your job is to create it and explain it.
