Visualization IFrame API

With third party visualization, you can easily integrate Elfsquad with external programs to visualize your configurations. For example, you can use Verge3D or Sketchfab to enhance your user experience and showcase your products in a more compelling way.

To embed a third party viewer in Elfsquad, an iframe is used. Communication between Elfsquad and the viewer is accomplished using the iframe postmessage API.

Events​

Elfsquad sends several events to the embedded iframe, such as when a configuration is modified.

Each event consists of two properties: the name property, which identifies the type of event, and the args property, which contains the relevant data.

elfsquad.configurationUpdated​

This event is sent whenever the configuration is modified.

window.parent.addEventListener('message', function(e) {                
    if (e.data && e.data.name === 'elfsquad.configurationUpdated') {
        const configuration = e.data.args;
    }
});

elfsquad.stepChanged​

This event is sent whenever the user changes step.

window.parent.addEventListener('message', function(e) {
    if (e.data && e.data.name === 'elfsquad.stepChanged') {
        const step = e.data.args;
    }
});

Commands​

You can also instruct Elfsquad from within the viewer by sending messages to it. These messages are similar to the event messages and contain a name property for the name of the message and an args property for the message arguments.

By sending these messages, you can instruct Elfsquad to perform various actions, such as updating the configuration.

elfsquad.triggerConfigurationUpdated​

This triggers a elfsquad.configurationUpdated event to be send, without updating the configuration.

window.top.postMessage({
    name: 'elfsquad.triggerConfigurationUpdated'
}, '*')

elfsquad.updateRequirement​

This executes an update requirement API call.

window.top.postMessage({                    
    name: 'elfsquad.updateRequirement',
    args: {
        nodeId: {nodeId},
        value: {value}, 
        isSelection: false
    },
}, '*');

elfsquad.updateRequirements​

This executes an API call to update multiple requirements.

window.top.postMessage({                    
    name: 'elfsquad.updateRequirements',
    args: {
        ignoreConflicts: false,
        includeSearchbarResults: false,
        requirements: [
            { nodeId: {nodeId}, value: {value}, isSelection: false },
            { nodeId: {nodeId}, value: {value}, isSelection: false },
            { nodeId: {nodeId}, value: {value}, isSelection: false },
        ],
    },
}, '*');

elfsquad.updateImageValue​

This command uploads an image and assigns it as a image value to a node.

window.top.postMessage({                    
    name: 'elfsquad.updateImageValue',
    args: {
        nodeId: {nodeId},
        image: {base64EncodedImageData}
    },
}, '*');

elfsquad.updateTextValue​

This command updates the text value of a node

window.top.postMessage({                    
    name: 'elfsquad.updateTextValue',
    args: {
        nodeId: {nodeId},
        textValue: 'text_value',
    },
}, '*');
