Using Jocly in a Web page

Insert this line to your HTML source code:

<script src="node_modules/jocly/dist/browser/jocly.js"></script>

You are now ready to use the Jocly API through the Jocly global object.

Using Jocly in a node.js application

const Jocly = require("jocly");

You are now ready to use the Jocly API through the Jocly entry point.


  • install the node.js environment (using nvm is probably a good idea)
  • install gulp: npm install -g gulp
  • install git
  • clone Jocly from github: git clone
  • enter the jocly directory
  • download required modules: npm install
  • build: gulp build
  • dist/browser contains the javascript library to build web applications, dist/node is the module to be used for node.js applications


  • using gulp build watch instead of gulp build makes gulp start watching files after the build. Whenever a file is changed, a build is automatically generated
  • you can use --no-default-games to prevent including the game modules from directory, and --modules <colon-separated-directories> to specify additional game modules to include. For instance, gulp --no-default-games --modules src/games/chessbase:src/games/checkers build will only generate distribution for Chess and checkers games
  • you can specify the games to be built in the distribution with the --games option. For instance, gulp --no-default-games --modules src/games/chessbase --games xiangqi:classic-chess build only generates Jocly for Classic Chess and XiangQi
  • using the no-obsolete option filters out the games marked as obsolete
