bracketzada

A JavaScript library for tournament brackets generation. Design your own way, Bracketzada do the rest. Live example: https://katreque.github.io/bracketzada/

Why?

Most of tournament bracket generators/libs implement algorithms and create components for you. Bracketzada has the idea to provide an API to generate and manage tournaments while you create and design your own frontend. The freedom you want, the power you need.

Types

Implemented:

• Simple Elimination

Future:

• Double Elimination
• Swiss Brackets

Quick Start

Install bracketzada via npm on your project:

npm install bracketzada --save

Import both Player and Tournament classes and generate Tournament Brackets object, with all the info you need.

let {Player, Tournament} = require('bracketzada');
let players = [
        new Player(0, 'Kappa'),
        new Player(1, 'Keppo'),
        new Player(2, 'PogChamp'),
        new Player(3, '4Head')
      ];
let championship = new Tournament(players);
let brackets = championship.generateBrackets();
