Designers will usually use the SketchApp1 app to create beautiful UI components...
Now, Designers can simply drag and drop the SketchApp project file (*.sketch) containing the UI component into xLayers to preview their creation directly inside the browser.
xLayers even has a 3D viewing mode allowing both Designers and Developers to preview all the layers that compose the UI component, and inspect their size, position and color properties.
Developers would usually use xLayers to export the UI component made with the SketchApp app as an Angular, Vue or React component and import it into an existing application.
xLayers is fully Open Source and available on GitHub.
