ChessApi

Gem Version Ruby Style Guide CI

chess_api is a gem that wraps Chess.com's Published-Data API.

Installation

Codespaces

Open in GitHub Codespaces

Add to an existing project

Add this line to your application's Gemfile:

gem 'chess_api'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install chess_api

Usage

To interact with the ChessApi, you'll first need to create a client object. You have the option of specifying a Faraday adapter.

client = ChessApi::Client.new
# or
client = ChessApi::Client.new(adapter: your_adapter_here)

From there, you'll be able to perform several operations:

Fetch a player on Chess.com by username

irb(main):018:0> player = client.player.retrieve(username: "GothamChess")
=>
#<ChessApi::Player:0x000000013bc41198
...

irb(main):019:0> player.username
=> "gothamchess"

irb(main):020:0> player.title
=> "IM"

irb(main):021:0> player.is_streamer
=> true

irb(main):022:0> player.twitch_url
=> "https://twitch.tv/GothamChess"

As you can see in the example above, you can access the fields returned by the Chess.com API through standard Ruby method syntax.

Fetching a list of players with a particular title on Chess.com

irb(main):001:0> client.titled_player.with_title(title_abbreviation: "WGM")
=>
#<ChessApi::Collection:0x000000013ecc78d0
 @data=
  [#<ChessApi::TitledPlayer:0x000000013f175d78 @attributes=#<OpenStruct username="abrahamyan-la">>,
   #<ChessApi::TitledPlayer:0x000000013f175620 @attributes=#<OpenStruct username="adriananikolova">>,
   #<ChessApi::TitledPlayer:0x000000013f175260 @attributes=#<OpenStruct username="advantagelucy">>,
   #<ChessApi::TitledPlayer:0x000000013f174ec8 @attributes=#<OpenStruct username="ahachess">>,
   ...
  ]

irb(main):002:0> client.player.online_status(username: "ryanjcaldwell")
=> "online"

Fetching the clubs that a player belongs to on Chess.com

irb(main):001:0> clubs = client.player.clubs(username: "GothamChess")
=>
#<ChessApi::Collection:0x000000015dbe5998
...

irb(main):002:0> clubs.data.map { |club| [club.name, club.joined] }
