Device Emulation

bonk can emulate mobile and tablet devices by setting viewport dimensions, device scale factor, touch support, and user agent.

Emulate a Device

err = page.Emulate(bonk.IPhone15)

This sets:

• Viewport dimensions
• Device scale factor
• Mobile flag
• Touch emulation
• User agent string

Built-in Presets

Custom Devices

Create your own device profile:

myDevice := bonk.Device{
    Name:              "Custom Tablet",
    UserAgent:         "Mozilla/5.0 (Linux; Android 13; ...) ...",
    ViewportWidth:     800,
    ViewportHeight:    1280,
    DeviceScaleFactor: 2,
    IsMobile:          true,
    HasTouch:          true,
}

page.Emulate(myDevice)

Manual Viewport

Set viewport without emulating a full device:

page.SetViewport(1440, 900)
