This example shows how to use 51Degrees On-premise device detection to determine details about a device based on its User-Agent and User-Agent Client Hint HTTP header values.
This example is available in full on GitHub.
This example requires a local data file. The free 'Lite' data file can be acquired by
pulling the git submodules under this repository (run `git submodule update --recursive`)
or from the device-detection-data
GitHub repository.
The Lite data file is only used for illustration, and has limited accuracy and capabilities.
