Nice! I never found that in any of my searches, and that's an awesome ability. It helps very much.

Note the launch command appears to have become ubuntu-app-launch instead of upstart-app-launch, but otherwise it works as advertised. My default browser is Firefox, which did not play well with this facility. Chromium on Debian works perfectly.

glad it helps :), might be usefull to write an up to date turorial for ubports community then

<shameless stud>You can also use Logviewer to check the log and conveniently copy it to paste.ubuntu.com for later investigation, if you spot an error while you're on the go.</shameless stud>

That would be very much appreciated! Feel free to post something on wiki.ubports.com

Have a look at:
https://wiki.ubports.com/wiki/Web-Browser-app-debugging
and wordsmith it if you can think of nice changes. Thanks!

(BTW, not clear how to link it into the rest of the document hierarchy.)

I'm discovering this thread. The tuto URL changed and now is http://docs.ubports.com/en/latest/appdev/webapp/webdebug.html

However, it looks like it doesn't work anymore. I did the 3 steps:

export QTWEBENGINE_REMOTE_DEBUGGING=0.0.0.0:9221
morph-browser --desktop_file_hint=/usr/share/applications/morph-browser.desktop [web_site_url]
Open http://YOUR_UT_IP_ADDRESS:9221 with chromium

And it says connection refused.

IIRC 3 years ago the browser was not yet Morph.
So I guess a lot changed since.

Maybe someone know the modern way to debug webapps with Morph.
It might be better to open a new thread in this regard I guess

Fla

I think the doc has been updated since then, as the command is morph-browser as stated above.

Oh, right.
Sorry I didn't pay enough attention to the command lines.
