design-code-prototype-kit

Contains prototype pages for design codes they can be exported into the platform at a later date once user testing is done

Run locally

1. Install Node.js 26 and npm. If you use nvm, run nvm use to pick up the version in .nvmrc.

2. Install the project dependencies:

   npm install

3. Start the prototype:

   npm run dev

Deploy to Heroku

The Procfile starts the prototype with npm start, and package.json pins Node.js 26 (LTS). Heroku sets NODE_ENV=production and PORT for you, so the Prototype Kit turns on password protection and redirects to HTTPS.

Set these config vars in the Heroku app:

Name	Required	Purpose
PASSWORD	Yes	Password participants enter to view the prototype. Without it the site shows an error page.

Deployments are handled automatically by Heroku on pushes to main.
