Bracket

Ladder tournament system meant to be easy to use. Bracket is written in async Python (with FastAPI) and Next.js as frontend using the Mantine library.

Setup

Database

First create a bracket cluster:

sudo pg_createcluster -u postgres -p 5532 13 bracket
pg_ctlcluster 13 bracket start

Subsequently, create a new bracket_dev database:

sudo -Hu postgres psql  -p 5532
CREATE USER bracket_dev WITH PASSWORD 'bracket_dev';
CREATE DATABASE bracket_dev OWNER bracket_dev;

You can do the same but replace the user and database name with:

• bracket_ci: for running tests
• bracket_prod: for a production database

The database URL can be specified per environment in the .env files (see config).

Config

Copy ci.env to prod.env and fill in the values:

• PG_DSN: The URL of the PostgreSQL database
• JWT_SECRET: Create a random secret using openssl rand -hex 32
• CORS_ORIGINS and CORS_ORIGIN_REGEX: Specify allowed frontend domain names for CORS (see the FastAPI docs)
• ADMIN_EMAIL and ADMIN_PASSWORD: The credentials of the admin user, which is created when initializing the database

Running the frontend and backend

The following starts the frontend and backend for local development:

Frontend

cd frontend
yarn
npm run dev

Backend

cd backend
pipenv install -d
pipenv shell
./run.sh
