ElectorZ - Backend

ElectorZ is a political game based on geographical strategies.

This repository hosts the backend of the ElectorZ web application, written in FastAPI. The code of the frontend is available in the Electorz Frontend repository.

Configuration

The entire project configuration is defined in an environment file, of which a template is present in the repository. To bootstrap the configuration, launch the following command:

make .env

You may then modify the following environment variables to configure the ElectorZ backend:

• APP_HOST: IP address on which the server listens
• APP_PORT: port on which the server listens
• FRONTEND_URL: URL of the frontend (to enable CORS)
• MONGO_HOST: host of the MongoDB instance
• MONGO_PORT: port on which the MongoDB instance listens
• MONGO_DB_NAME: name of the MongoDB database
• MONGO_USERNAME: name of the MongoDB user
• MONGO_PASSWORD: password of the MongoDB user
• MONGO_TLS: boolean that indicates if TLS must be enabled to connect to the MongoDB instance
• MONGO_MAX_CONNECTIONS: maximum number of connections to the MongoDB instance
• MONGO_MIN_CONNECTIONS: minimum number of connections to the MongoDB instance

Installation

You can install the pip requirements by launching the following command:

make install

MongoDB instance

If you do not have a MongoDB instance available for the ElectorZ application, you can launch a dockerized version of MongoDB by launching the following command:

make stack

It will automatically provision the database with the JSON files present in the db-init directory.

Note that a mongo-express image has been added to the docker-compose file to help you manage the database: it provides a web administration tool available at http://localhost:8081.

Launching the application

Once a MongoDB database is available with the configuration options provided in the environment file, the ElectorZ backend application may be launched with the following command:

make start

Documentation

FastAPI provides automatic documentations thanks to the Swagger & Redoc modules: you can for instance visit http://localhost:8080/docs to get all information about the API and test the routes.
