Chess Players

Utility for accessing chess player data

Intro

This NodeJS package is provided to help developers build applications or components which want to use the published chess player rating list data.

An example of this would be a React Component which renders a players profile i.e., name, country, rating - where the component prop accepts the FIDE id from a REST endpoint you expose on your server.

This information is found here at the FIDE website.

Getting started

npm install chess-players

or

yarn add chess-players

Examples (typescript)

Full list

import Fide, { Player } from './fide';
 
(async () => {
  const fide = new Fide();
  const players: Array<Player> = await fide.getPlayers();
 
  console.log(`Players: ${players.length}`);
})();

Top players

import Fide, { Player } from './fide';
 
(async () => {
  const fide = new Fide();
  const players: Array<Player> = await fide.getPlayers();
 
  const topTen = players
    .sort((a: Player, b: Player) => b.rating - a.rating)
    .slice(0, 10)
    .reduce(
      (players: any, player: any) => 
      [...players, { name: player.name, rating: player.rating, nationality: player.country }],
      [],
    );
 
  console.log(topTen);
})();

Specific player

import Fide, { Player } from './fide';
 
(async () => {
  const fide = new Fide();
  const players: Array<Player> = await fide.getPlayers();
 
  const player = players.find(player => player.fideid === 418250)
 
  console.log(player);
})();

Legacy lists

import Fide, { Player, Options } from './fide';
 
(async () => {
  const fide = new Fide();
  const config: Options = {
    ratingType: "rapid",
    month: "jan",
    year: 2019
  }
  const players: Array<Player> = await fide.getPreviousPlayersList(config);
})();

Memoized (cached API calls)

import Fide from './fide';
 
(async () => {
  const fide = new Fide();
  console.time('players');
  await fide.getPlayers();
  console.timeEnd('players');
 
  console.time('players-memoized');
  await fide.getPlayers();
  console.timeEnd('players-memoized');
})();
