This is a war simulation app implemented using a Flask localhost server and a Postgres database. To conifgure the database, change the variables in the config.ini file.

All necessary packages are included in the requirements.txt. Run the following command to install with pip:

$ pip install -r requirements.txt

Prior to running the app, initialize the database by running:

$ python init_db.py

To access the app, run app.py and go to http://127.0.0.1:5000/war . Endpoints can be accessed with the following URLs:

http://127.0.0.1:5000/simulate 

http://127.0.0.1:5000/ <playerid> 

Pressing the buttons in the app will call the endpoints, which can be found within app.py. The war.py file contains the war simulation code and is called by the endpoints. Scores are persisted in the database, but can be reset by pressing the reset button.

The UI was implemented using Dash, which provides html elements in Python and callback capabilities.

Endpoint testing can be found in the endpoint_test.py file.

Given more time, I would have liked to build a more full fledged app following an MVC framework. Given the application just has one page, I felt that this might not be necessary, and I prioritized speed of production. To put both the endpoint and dash app under the same host, I put the code in the same file, although I would have prefered modularizing them into different files. Given more time, I also would have liked to host the application on a server, and build out a UI so that the user can visualize each round of the simulated game.
