Sports Standings App

Single-page application for managing multiple sports tournaments (Premier League, Eurobasket, Wimbledon).

Users can:

• Add teams / players
• Add match results (each pair plays only once)
• View automatically calculated standings

State persists between refreshes.

Getting Started

Prerequisites

• Node.js >= 18
• npm or yarn

---

Installation

Clone the repository:

git clone https://github.com/baudenis/tournaments.git

Install dependencies and run the app

npm install
# or
yarn install

Start the development server:

npm run dev
# or
yarn dev

Architecture

• Feature-based structure (features/tournament)
• Redux handles domain state and data integrity
• UI-level validation handled in custom hooks
• Shared UI components live in shared/ui

Persistence

Tournament state is persisted to localStorage. Persistence is best-effort and fails gracefully to avoid breaking the app in restricted browser environments.
