Pointer for those debugging web apps
-
I of course mostly develop on my desktop Chromium browser, but every now and then I have a problem which only happens on my UBports browser. I found the file:
.cache/upstart/application-legacy-webbrowser-app-.log
which is the only place I've been able to find Javascript errors.
Also note that the browser is very, very clingy to JS source files, a reload of the overall app will often not update the contents of the JS source referenced from the app.

there is possibility to remotely debug browser webapps, if that helps: link

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>

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=0.0.0.0:9221morph-browser --desktop_file_hint=/usr/share/applications/morph-browser.desktop [web_site_url]- Open
http://YOUR_UT_IP_ADDRESS:9221with 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 -
I think the doc has been updated since then, as the command is
morph-browseras stated above. -
@Fla
Oh, right.
Sorry I didn't pay enough attention to the command lines.
