#40850 — Running user scripts in an Android browser?

Not sure if this is OT as it's more about the operating environment
than the language per se, but ... I've written some javascript to 
extract data from a webpage DOM and present it in a format more
to my liking. I can run it on a desktop or laptop by loading the 
web page in Firefox and pasting my script into the console.

But none of the browsers on my phone offer a javascript console.
Does anyone know of a workaround for this or and Android browser
with more hackability?

what about using google and the keywords like:
"chrome developer tools on mobile"
of course, without quotes?

there are several hits, like:

Thanks, with much fiddling I was able to get it to work but only when 
connected over USB to a laptop also running chrome. Not quite the
workflow I was hoping for. So I put my code in an email to the website
support with screenshots and an explanation of why their output wasn't 
quite right and needed help of this sort.

So, maybe they'll fix it for me and then I won't have to run a user script 
at all. fingers crossed.

Nope. As far I know all mobile browsers rely on desktop computers via
USB to provide debugging via the desktop version of the respective browser.

Thanks, I've turned to a more elaborate, but probably more fun route.
I installed Fdroid and then Termux and inside Termux I got emacs,
git, and nodejs appearing to work (still need to get evil mode going). 
So I can either save the page from the browser and then manipulate 
the saved html, or fetch the page without a browser and use an html 
parser or something like `cheerio` to generate a DOM that I can then 
query.

My other option is to write my own html parser in like C or something.
That sounds like a lotta work, sigh.
