Reactome's DiagramJs widget is our diagram viewer in an ordinary JavaScript API. It is meant to be reused by third party resources in order to display Reactome Pathway Diagrams directly in their web pages and enable users to interact with them.

Reusing Reactome's Diagram Widget?

To reuse our viewer you need to follow the following steps

1. Include the diagram javascript dependency in you HTML header

<script type="text/javascript" language="javascript" src="https://reactome.org/DiagramJs/diagram/diagram.nocache.js"></script>

2. Add a place holder in the body of your web page

<div id="diagramHolder"></div>

3. Create and initialise the diagram viewer from your javascript code

    //Creating the Reactome Diagram widget
    //Take into account a proxy needs to be set up in your server side pointing to www.reactome.org
    function onReactomeDiagramReady(){  //This function is automatically called when the widget code is ready to be used
        var diagram = Reactome.Diagram.create({
            "placeHolder" : "diagramHolder",
            "width" : 950, // minimum recommended width
            "height" : 500
        });

        //Initialising it to the "Hemostasis" pathway
        diagram.loadDiagram("R-HSA-109582");

        //Adding different listeners

        diagram.onDiagramLoaded(function (loaded) {
            console.info("Loaded ", loaded);
            diagram.flagItems("FYN");
            if (loaded == "R-HSA-109582") diagram.selectItem("R-HSA-109582");
        }); 

        diagram.onObjectHovered(function (hovered){ 
            console.info("Hovered ", hovered); 
        }); 

        diagram.onObjectSelected(function (selected){
            console.info("Selected ", selected); 
        });
     }
