Setup

Clone the repository and run npm install.

Development

• Terminal #1 - run React frontend npm run start => localhost:3000
• Terminal #2 - run express backend npm run server => localhost:3100

Production

Run npm run monty-app builds the React frontend and serves it via express using static middleware at localhost:3100.

Backend API

The express backend responds to POST request at localhost:3100/api/monty.

Request body

{
  "sampleSize":<Integer>,
  "keep":<Boolean>,
  "numberOfDoors":<Integer>
}

Response body

{
  "sampleSize": <Integer>,
  "wins": <Integer>,
  "keep": <Boolean>,
  "numberOfDoors": <Integer>,
  "winRate": <Float>
}

While in production the build React app is served from the same port as the backend; in order to cancel this feature it run rm -rf build in app root folder.
