    cytoscape-elk

    Description

    The elk layout algorithm adapter for Cytoscape.js (demo)

    This discrete layout creates good results for most graphs and it supports compound nodes.

    Dependencies

    • Cytoscape.js ^3.2.0
    • elkjs ^0.3.0

    Usage instructions

    Download the library:

    • via npm: npm install cytoscape-elk,
    • via bower: bower install cytoscape-elk, or
    • via direct download in the repository (probably from a tag).

    Import the library as appropriate for your project:

    ES import:

    import cytoscape from 'cytoscape';
    import elk from 'cytoscape-elk';
     
    cytoscape.use( elk );

    CommonJS require:

    let cytoscape = require('cytoscape');
    let elk = require('cytoscape-elk');
     
    cytoscape.use( elk ); // register extension

    AMD:

    require(['cytoscape', 'cytoscape-elk'], function( cytoscape, elk ){
      elk( cytoscape ); // register extension
    });

    Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

    API

    var options = {
      nodeDimensionsIncludeLabels: false, // Boolean which changes whether label dimensions are included when calculating node dimensions
      fit: true, // Whether to fit
      padding: 20, // Padding on fit
      animate: false, // Whether to transition the node positions
      animateFilter: function( node, i ){ return true; }, // Whether to animate specific nodes when animation is on; non-animated nodes immediately go to their final positions
      animationDuration: 500, // Duration of animation in ms if enabled
      animationEasing: undefined, // Easing of animation if enabled
      transform: function( node, pos ){ return pos; }, // A function that applies a transform to the final node position
      ready: undefined, // Callback on layoutready
      stop: undefined, // Callback on layoutstop
      elk: {
        // All options are available at http://www.eclipse.org/elk/reference.html
        // 'org.eclipse.elk.' can be dropped from the Identifier
        // Or look at demo.html for an example.
        // Enums use the name of the enum e.g.
        // 'searchOrder': 'DFS'
      },
      priority: function( edge ){ return null; }, // Edges with a non-nil value are skipped when geedy edge cycle breaking is enabled
    };
     
    cy.layout( options ).run();

    Build targets

    • npm run test : Run Mocha tests in ./test
    • npm run build : Build ./src/** into cytoscape-elk.js
    • npm run watch : Automatically build on changes with live reloading (N.b. you must already have an HTTP server running)
    • npm run dev : Automatically build on changes with live reloading with webpack dev server
    • npm run lint : Run eslint on the source

    N.b. all builds use babel, so modern ES features can be used in the src.

    Publishing instructions

    This project is set up to automatically be published to npm and bower. To publish:
