The challenge is to place several queens on a board without any of them able to hit another.

For this project the back-end will be hosted on heroku; which at the time of writing is not able to calculate the solutions on a 8x8 chessboard using the algorithm currently provided.

The backend is written in PHP and the front-end is written in VueJS. The cool thing about this solution is that it can calculate possible solutions for any pre-set board.

Pre-set boards can be made by clicking on the chess-tiles in the interface.

First time setup is to install the dependencies:

composer install

In the frontend folder

npm install

For running the backend traverse to the api folder and run this command:

php -S localhost:8000

For running the frontend traverse to the frontend folder and run this command:

npm run serve

Since the PHP backend is hosted on heroku, it can be deployed by pushing it to the heroku repository.

git push origin heroku

Front-end is hosted on firebase

firebase deploy

This application was written in a rush, therefore has no quality guarantee. It should be noted that the algorithm for calculating the possible solutions is not optimized and could quite easily be improved by at least a factor 4.
