Automatically detect Tauri v1/v2

[rodolfoBee]

Problem Statement

When using Sentry within a Tauri application, what gets detected from the user agent is somewhat misleading, e.g. Ubuntu/Safari. While not exactly false, since it is using gtk-webkit, it is not telling the whole story, so I think it would be a nice feature to detect the tauri version and platform instead.

Solution Brainstorm

To detect Tauri v1, you just have to look if window.TAURI is present; for v2, it is window.TAURI_INTERNALS. Tauri v1 supports Linux/Ubuntu, MacOS X and Windows. Tauri v2 additionally supports Android and iOS.

So instead of Ubuntu/Safari, it would be great to see Ubuntu/Tauri in the future.

So which "field" should become Tauri? The browser? is there a version?

My guess is that the web views used across each platform result in a user agent that results in a strange browser or device to be listed.

For example the web view in Tauri on macOS results in the client being listed as something like "Apple Mail". This is probably caused by whatever library Sentry uses for user agent parsing.

Tauri should be the browser, since it actual engine is apparent from the combination (Ubuntu = webkit-gtk, MacOS = webkit, Windows = blink-edge). A future version might ship with a Servo engine, but that is still WIP.

Unfortunately, the information from my mail was pasted directly into markdown, so the information was mangled. The properties are window.__TAURI__ and window.__TAURI_INTERNALS__.

Can you get a Tauri version from window.__TAURI__ or window.__TAURI_INTERNALS__?

[timfish]

You can currently inject this data into events via beforeSend:

Sentry.init({
  dsn: '__DSN__',
  beforeSend(event) {
    if('__TAURI__' in window || '__TAURI_INTERNALS__' in window) {
      event.contexts = {
        ...event.contexts,
        runtime: {
          name: 'Tauri',
          // You might be able to set a version or other data here
          // version: (window.__TAURI__ || window__TAURI_INTERNALS__).tauriVersion,
        },
      };
      // You might need to remove the User-Agent header so Sentry doesn't auto detect the browser
      // This might break platform detection though, needs testing... 🤔
      if (event?.request?.headers?.['User-Agent']) {
        delete event.request.headers['User-Agent'];
      }
    }
    return event;
  },
});

That is indeed a nice workaround. I guess a default behavior would be nice.
