To run the application clone it locally, install the dependencies, and then start the webpack dev server.

Note: Node must be installed to run the application.

git clone http://github.com/fortruce/phq9.git
npm install
npm start

Then, browser to http://localhost:3000 to see the application.

If you would rather not run the webpack dev server, then you can generate the production files and serve them from another server.

webpack -p
cd dist/
python -m SimpleHTTPServer 3000

The application was built on top of React and react-router. I initially set up routes for the quiz and the scoring.

The quiz route is responsible for presenting the user with the Phq9 quiz itself and then redirecting to the correct scoring route upon submission.

The scoring route determines whether the user scored high enough to warrant doctor recommendations and displays recommendations or a brief thank you message.

The entirety of the quiz lies withing Phq9.js and Question.js. With such a simple problem, I decided to store the quiz data in the state of the Phq9 component; however, I would normally store such data in a Flux based store.

The Question component is a pure component used to render each question and encapsulate the show/hide of the options.

To streamline the quiz taking process on smaller devices, I opted to initially hide the options for each question. The options only show for the next unanswered question, but they can be toggled easily by clicking on a question. The purpose was to keep the clutter down to a minimum.

When the user has answered all of the questions, the submission button will become enabled. The user is not allowed to submit until all questions are answered. The submission trigger adds up the score and redirects to the scoring route.

If a recommendation is necessary due to the score being high enough, the scoring route shows the Recommendations. The Recommendations simply renders a Recommendation component for each doctor available with a picture, name, and brief description. Each Recommendation also has a 'contact' button to allow the user to contact the specific doctor. The contact button simply redirects to a contact page that thanks the user for contacting that doctor.
