Going SPA when you don't know JS is very much a baptism of fire.
Angular is personally my favourite too and essentially forces the SPA
model. But it has a much bigger learning curve compared to Vue and
React (the other two common names thrown about nowadays). The others
are also easier to not force into a SPA model.
Figure what's the minimum requirement first ;-).
Single page is pretty close to the way the application currently works
so that is promising. It is a lightweight training framework. Simple
architecture of courses, instruction(s) and questions with answers
aggregating a total score for the student.
I won't publicise the URL because the server isn't heavy-duty. But if
there is any individual interest I'm happy to give it off-list. Today I
released the beta to the first client who (generously) is using it for
his troops to do online training on how to use some Windows software.
So back to the minimum requirement ...
The single (question) page has previous-question and next-question links
which morph into previous-instruction and next-instruction links when at
the first and last question respectively. So that is the SPA similarity.
When you click the [Save] button after answering a question there is no
indication the answer has been saved without adding a line of text (via
the view) after answer.save()
Refreshing the page resends the [Save] and reprints the line of text
saying the [Save] was successful. Too clunky.
It was that behaviour which made me start this thread.
I checked out typescript and it looks great but it is javascript. It
seems to let you code in ECMAScript 6 which is looking more like Python
and as Nick mentioned, has a compilation step (which I suppose is like a
minification step anyway) to get it into the version currently supported
by all browsers.
That prompted me to look more closely at a few of the transpilers in the
link I posted in the thread-starter. One stood out for me ...
http://www.transcrypt.org/
It seems the compilation to javascript takes place in the CI process and
it can be debugged in Python or Javascript. You can use both javascript
and/or python libraries. Written by a Dutchman which is possibly
interesting ;)
The Angular thing is interesting.
https://medium.com/@chriscordle/why-angular-2-4-is-too-little-too-late-ea86d7fa0bae
https://www.infoworld.com/article/3213244/javascript/whats-new-in-angular-5-easier-progressive-web-apps.html
From those articles, it seems React is lighter-weight than Angular and
for me that probably means easier to learn. It is still daunting though.
Vue also assumes javascript know-how.
I think my best plan is to postpone a decision and make a start on DRF
anyway. No matter what happens that is a prerequisite.
I hope it isn't wishful thinking but Transcrypt looks more attractive
than learning javascript plus a javascript framework.
Thanks to all for the excellent and very professional feedback.
Cheers

If that is the case - I would recommend looking into creating a
single page app - with Django restframework on the backend if you
want to continue with Django. For the frontend you will however be
required to learn some sort of JS framework - however this doesn't
have to be THAT bad. I personally like angular 5 - which is
written in typescript - a javascript based language - that
actually removes most of the pain. HOWEVER JS knowledge is good to
have anyway....
There are other frameworks that don't require that much JS
knowledge and Jason suggested GWT which sounds like it could be
worth a shot, as long as it doesn't add to much complexity. The
main reason for using that would be a large user base, so you can
get help. The python transpiled JS versions don't really have the
greatest user base :-)

That seems unanimous :(
Jani asked what problem I need to solve. Without going into
analytical detail, all the code is serverside and now the
project needs to move towards AJAX for user experience reasons.

Agree with everything already said.
Only thing I want to add is that while js has historically
been a horrible language, the modern standards have helped
rectify this. Modern js can be almost pleasant to work
with nowadays.
I wouldn't spend time transpiling python to js. Just try
to learn js and maybe transpile from a modern standard to
the browser standard. It's almost as easy as python to
pick up.
Django compressor helps greatly in the last case.

Hi,
You don't describe to what extent you need to use
JavaScript -
IOW, what problem you need to solve with JavaScript?
Depending you needs you might get away with basic
knowledge
and usage of some helpful JavaScript
library/framework.

However it

Interestingly, there are
now a number of Python -> Javascript transpilers.

Where would be a good place to start a
discussion on the
topic?
I am self-employed with multiple demands on
my time so I
cannot afford to allocate sufficient time to
learn it let
alone undertake formal Javascript training. My
hope is to
pick it up by osmosis and wonder if a
transpiler would help.
Thanks for any pointers
