Travis Build Status

The Go Lightweight Frontend

Glift is a modern javascript client for the game Go Glift was created to be a modern Go UI that supports mobile and desktop alike. It was built from the beginning to support:

  • Viewing games
  • Studying go problems
  • Constructing complex go lessons


Here's a simple example, to create a game viewer for a game in div.

        divId: 'myId',
        sgf: 'mysgfs/lee_sedol_vs_gu_li.sgf'

See if you want to see Glift in action and lots of code samples!

How it works:

Glift is an SVG based UI. When you invoke glift.create, Glift, looks at the div, determines the height and width of the div, and then draws an instance of the board.

Supported Browsers

The complied Glift JavaScript is completely self-contained and supports the following browsers:

  • Chrome
  • Chrome on Android
  • IE 9+
  • Firefox
  • Opera
  • Safari
  • Safari on iOS

Unsupported browsers

  • IE 6-8
  • Native Android Browser


Glift is now released on a public, stable release!! All methods and options that are part of the stable 1.0 API have been marked with 'api: 1.0'. Similarly, if an option is available from 1.1 onward, then it will be marked 'api: 1.1'.

lifetime of the 1.0 release have been marked with api: 1.0. Options/methods that are on track to become supported have been marked @api(beta).

The currently supported methods support @api(1.0):

And the following options (see src/widgets/options/base_options.js)

  • divId - ID of the container div.
  • sgf - String, url, or object, with options from sgfDefaults.
  • sgfCollection - Array of SGFs
  • initialIndex - Where to start in the SGF collection
  • sgfDefaults
    • sgfString - String for the SGF. Only specified in sgf objects.
    • url - URL of the sgf. Only specified in sgf objects.
    • widgetType - The type of the Glift widget. Defaults to GAME_VIEWER.
    • initialPosition - Where to start initially.
    • boardRegion - The region of the borad to display. Defaults to AUTO.
    • problemConditions - The conditions for getting a problem correct.
    • uiComponents - UI components to use.
  • display - Display variables
    • goBoardBackground - URL for a go board background image.
    • theme - The Glift theme
    • drawBoardCoords - Whether or not to draw go board coordinates.


Although Glift was built for all major browsers, Glift was built on OSX, so these development docs assume a POSIX toolchain.

Glift uses Glup and Nodejs. Before you begin, make sure you've installed:

Gulp Instructions

Initialization. First, you'll need to initialize the repository with the relevant node modules:

npm install

This will create the necessary node_modules directory, which should be ignored via the .gitignore

Running Tests

There are several ways to run the qunit tests. To simply run the QUnit Tests via gulp:

gulp test

Or, once you've run gulp test or gulp update-html-srcs you can just open test/htmltests_gen/QunitTest.html in a browser and run the tests there (it's bit faster). Running the aformentioned commands dynamically inserts the sources into the HTML test templates in the test/htmltests directory and outputs the templated files to test/htmltests_gen.


To compile the JavaScript, run:

gulp compile

Automated Build+Testing

To both build and run the tests, run:

gulp build-test

This is the command run by the Travis continuous integration suite.

Editing documentation

If you find yourself editing the Markdown docs, I use the node script Markdown Preview. It's then used via the following:

markdown-preview [options] <filename>

or in Vim:

au Filetype markdown command! PrevMarkdown !markdown-preiew %
You can’t perform that action at this time.
