Use for browser extensions

[marcelreppi]

I wanted to use umami to track events in a browser extension, however I can't make it work for some reason.
Using the script tag doesn't work due to CSP I got it working only for the Vue.js files of my browser extension but not for any background scripts. I tried downloaded the script and import it instead and do the tracking via JS but umami is not added to the window object for the background scripts.

Any ideas how to get this working for browser extensions?

Thanks!

I now got it working just for the Vue.js files of my browser extension by setting the content_security_policy in the manifest.json and using the script tag as usual in my index.html.
However I still have an issue using it in background scripts. umami is not available on the window object.

EDIT: I guess the issue is this line since I import the tracker script via my manifest.json and there is no script tag for background scripts.

I got it working for background scripts by using a background page instead of single scripts but that kind of breaks my application.
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/background

  "background": {
    "page": "my-background.html"
  }

I would highly prefer using the scripts syntax 😞

  "background": {
    "scripts": ["umami.js", "my-background.js"]
  }

Got it working now with the script syntax by altering the downloaded umami.js file the following way:

1. m = v.querySelector("script[data-website-id]") to m = v.querySelector("script[src*='umami']")
2. w = g("data-website-id") to w = "WEBSITE_ID"
3. y = g("data-host-url") to y = "HOST_URL"

Hope this helps anyone running into the same issue.

Maybe you could make it more easily usable for browser extensions in the future :)

Not sure what a browser extension would be for, but moving this to discussions since it's not an issue.
