well, if you really will go to the limet of low level here is a powerEXT
complete maintenance program:
// Create Function
setContent();
echoExtHTML(pExtFunction:'start');
echoExtHTML(pExtFunction:'endFiles');
setExtConfig('cgi.lib':pExtCgiPath('PX'));
setExtConfig('cgi.db2lib':pExtRpcPath('PX'));
setExtConfig('cgi.db2rpc':'pxsvpxwa');
rpcreq = pExtRequest('PXSVPXWA':'');
setExtConfig('cgi.db2req':rpcreq+' ');
rpcreq = pExtRequest('PXSVPXWA':'getRows');
setExtConfig('cgi.db2download':rpcreq+' ');
echoExtConfig(pExtFunction);
echoExtGridKeyField('PXWUSC');
echoExtGrid(pExtFunction);
echoExtForm(pExtFunction);
echoExtHTML(pExtFunction:'endScript');
echoExtHTML(pExtFunction:'endBody');
// Send and Exit
echoToClient();
pExtStat();
return;
Ok, there is a little definition file involved:
<design>

Like Valence powerEXT has low-code RPG API's that generates javascript that
goes into
the Sencha EXT JS low-code API's and creates the EXT JS Application, the
rest is a simple
autogenerated REST/CRUD service that handles the DB I/O.
BTW it is written in 2009 so there is nothing new other than the word
"Low-code" that we
on that time called a framework.
If you want to see what the server generates look at this running app of
the above code and
display the source: (note it takes time to load first time due to heavy JS
files)

I did receive off-list references to no-code and low-code offerings from
CNX Corp and Sencha, including a query utility, a data-file utility, and a
data-file app generator.

I pass along the reference, not to promote specific products, but to
consider the nature of no-code and low-code tooling. I tend to view such
utilities as supplementary to, rather than a basis for new business
application development.
Of the three tools referenced via private reply, the one that I viewed as
most likely to gain traction was the query utility because that is the type
of thing that shows up in RFPs on a fairly regular basis.
Data-file utilities may be productive for developers, but they're somewhat
a kin to torture for end-users; the templates that they are based on are
too primitive, and restrictive. There doesn't appear to be much (if any)
provision for data validation, referential integrity constraints, custom
business rules, and end-user error handling.
