Twenty Questions

This is a React app in TypeScript for playing the Twenty Questions game.

Note that you will need an OpenAI API account in order to run this.

Setting up the OpenAI API Key

You need to set up your OpenAI API key as an environment variable. Here's how to do it:

Windows (PowerShell)

$env:REACT_APP_OPENAI_API_KEY="your-api-key-here"

Windows (Command Prompt)

set REACT_APP_OPENAI_API_KEY=your-api-key-here

macOS/Linux

export REACT_APP_OPENAI_API_KEY=your-api-key-here

Replace your-api-key-here with your actual OpenAI API key. The environment variable must be set before starting the development server.

Running the Application

In the main directory, you can run:

• npm install (run once)
• npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.

Running the Unit Tests

The application includes unit tests for the AI prompt generation and validation functions. These tests ensure that:

• Question prompts are correctly formatted with all necessary information
• Previously used objects are properly tracked and included
• Response validation works as expected for both first and follow-up questions
• Other misc. tests

To run the tests:

• npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
