Receive information about the user system

[hendrikebbers]

To provide a automatic download selection we need information about the user system

Which OS is the user using? (Win32, Win64, MacOS, Linux, ...)



[Added 18/04/21 by @hiddenmind3]:

• Retrieve the user agent header from the browser
• Get the Operating System from the useragent (win, mac, linux, solaris, ...)
• Get the Architecture from the useragent (x32, x64, amd, ...)
  • If architecture cant be found use the default of the operating system (eg. Windows-x64)
• Return the values in a “UserSystem” class

Note, Safari isn't the best about reporting architecture, see also: WICG/ua-client-hints#105 (comment)

Hi there -- quick question: I added the Sec-CH-UA-Bitness header to the UA Client Hints spec, which reports on the "bitness" of the platform / OS, but have been thinking it may be useful to know the bitness of the app (browser) in addition to the OS.

For example, if you're running 32 bit Firefox or Chrome, on a 64 bit Windows. Is that useful for your use-case?

@miketaylr We're primarily interested in the OS and architecture of the host because we want to offer the right download. So when do I have a 32 bit browser on a 64 bit OS? I guess if the browser isn't ready for 64 bits. So I have a hard time to imagine when that info could be useful for our use case. But happy to be convinced otherwise.

Thanks -- that's helpful. No need to force a use case. :)
