Device Frame Addon

The Device Frame Addon is an invaluable tool that lets you preview your use-cases on various device frames. These frames provide a realistic environment by introducing constraints for width and height, resembling actual devices. They override MediaQuery parameters to ensure your component behaves as expected across different devices.

Setting up the Device Frame Addon in your Widgetbook is straightforward. Let's walk through the steps:

Step 1:#

The first step is identifying which devices you want to preview your components. You can select from a predefined list of devices. Here's an example with a selection of iPhone models:

devices: [

Step 2 (Optional):#

As an optional step, you can define a default device to be displayed when the Widgetbook app launches. If you do not specify an initialDevice, the first device in your list is selected by default. In this example, we're setting the iPhone 13 as the default device:

initialDevice: Devices.ios.iPhone13,

Step 3:#

Construct the Device Frame Addon with your devices and initialDevice defined, you can now create the Device Frame Addon using the DeviceFrameAddon class. This class takes in your device list and, optionally, the initialDevice:

This setup will launch your Widgetbook app with the iPhone 13 screen constraints by default, enabling you to swiftly check your widgets' responsiveness and visual consistency on this device. You can then quickly switch to the other defined devices to compare results. Please note that the actual appearance of the preview may vary depending on the specific features and constraints of the chosen device models.
