WhoAmI WebAssembly Documentation

Web (Browser)

By default, when WhoAmI is compiled for Wasm32 unknown (neither -wasi or -daku), WhoAmI links to web-sys and defaults values to browser information:

  • realname(): "Anonymous"
  • username(): "anonymous"
  • lang(): Browser preferred language list
  • devicename(): Browser name (Example: "Firefox 110.0")
  • hostname(): "localhost"
  • platform(): Host operating system by view of browser (Example: "Linux")
  • distro(): Host distro by view of browser (Example "Unknown Linux")
  • desktop_env(): "Web Browser"

Fake

If you compile WhoAmI with default-features = false, WhoAmI will not bind to web-sys, and will instead return these fake values:

  • realname(): "Anonymous"
  • username(): "anonymous"
  • lang(): "en-US"
  • devicename(): "Unknown"
  • hostname(): "localhost"
  • platform(): "Unknown"
  • distro(): "Emulated"
  • desktop_env(): "Unknown"

Wasi (Wasite)

Building WhoAmI targeting Wasi will assume the wasite environment variables are set, as Wasi alone does not currently support the functionality WhoAmI requires.

  • realname(): $USER - Fallback "Anonymous"
  • username(): $USER - Fallback "anonymous"
  • lang(): $LANGS - Fallback "en-US"
  • devicename(): $NAME - Fallback "Unknown"
  • hostname(): $HOSTNAME - Fallback "localhost"
  • platform(): "WASI"
  • distro(): "Unknown WASI"
  • desktop_env(): Unknown($DESKTOP_SESSION) - Fallback "Unknown WASI"

Daku (Quantii, other Ardaku environments)

WhoAmi will depend on currently unstable portals in the Daku specification.
