Database architecture

One table named currencies with PK named id, currency as currency, timestamp as date_, price as price.

How to run

1. Rename .env.template to .env
2. Paste your KuCoin API_KEY and SECRET_KEY there
3. Pick one of the options below

Docker compose way

Run the following command:

docker-compose up --build

Local way

Alternatively, you may want to run a server without PostgreSQL and nginx. In this case, you can use the commands below:

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python src/app.py

Last command may be replaced by gunicorn command:

gunicorn app:factory --bind 127.0.0.1:8000 --worker-class aiohttp.GunicornWebWorker --reload

You'll also have to apply database migrations manually in this case (alembic upgrade head from src directory), and adjust database environment variables inside .env file.
