    distanceTo(node) returns the distance from the source node to node, and pathTo(node) returns a collection containing the shortest path from the source node to node.  The path starts with the source node and includes the edges between the nodes in the path such that if pathTo(node)[i] is an edge, then pathTo(node)[i-1] is the previous node in the path and pathTo(node)[i+1] is the next node in the path.

    Selectors <

    Notes & caveats

    A selector functions similar to a CSS selector on DOM elements, but selectors in Cytoscape.js instead work on collections of graph elements. Note that wherever a selector may be specified as the argument to a function, a eles.filter()-style filter function may be used in place of the selector. For example:

    -
    cy.$('#j').neighborhood(function( ele ){
+
    cy.$('#j').neighborhood(function( ele ){
   return ele.isEdge();
 });
    
 
    The selectors can be combined together to make powerful queries in Cytoscape.js, for example:
    
 
    // get all nodes with weight more than 50 and height strictly less than 180
-cy.elements("node[weight >= 50][height < 180]");
    
+cy.elements("node[weight >= 50][height < 180]");

    Selectors can be joined together (effectively creating a logical OR) with commas:

    // get node j and the edges coming out from it
-cy.elements('node#j, edge[source = "j"]');
    +cy.elements('node#j, edge[source = "j"]');

    It is important to note that strings need to be enclosed by quotation marks:

    -
    //cy.filter('node[name = Jerry]'); // this doesn't work
-cy.filter('node[name = "Jerry"]'); // but this does
    +
    //cy.filter('node[name = Jerry]'); // this doesn't work
+cy.filter('node[name = "Jerry"]'); // but this does

    Note that some characters need to be escaped for IDs, field names, and so on:

    -
    cy.filter('#some\\$funky\\@id');
    +
    cy.filter('#some\\$funky\\@id');

    Some examples of these characters include ( ^ $ \ / ( ) | ? + * [ ] { } , . ). Try to avoid using non-alpha-numeric characters for field names and IDs to keep things simple. If you must use special characters for IDs, use a data selector rather than an ID selector:

    -
    cy.filter('[id = "some$funky@id"]');
    +
    cy.filter('[id = "some$funky@id"]');

    Group, class, & ID

    1. Create a repository on GitHub for your extension’s code
      2. 
 
    2. Use rollup-starter-lib to create the project’s scaffolding.  Alternatively, manually generate the project configuration files with your favourite bundler.
      3. 
 
    3. Use Babel if you want to support older browsers with your extension.  The rollup-starter-lib repo has an example in the babel branch.
      4.

    4. The default export of your extension should be a registration function, e.g.:
