Good morning, fellow developers.

It is now almost 15 years ago i started with OFBiz. I always followed 
new technology developments and used them when they became usable in 
a production environment. That is why i joined OFBiz early. I also 
proposed years ago to go from svn to git that now finally is approved 
for OFBiz. I also proposed to replace the OFBiz framework with 
Moqui.org, yes I know a much bigger change but believe me, that will 
also happen one time for you.


We now support Moqui for about a year and the main reason we switched 
over is the excellent REST interface Moqui has. This allows you to 
have a user interface fully independent from Moqui, yes a website or 
a mobile application just using the data from Moqui via REST. All 
screen rendering is now done with for example the vue.js framework 
using javascript in the client, not using ftl at all, improving the 
user interface experience dramatically. So all templates and the 
rendering is in the client making it completely static and can be 
loaded from cdn networks.


My advise? If you want to extend the life of OFBiz implement a REST 
interface quickly...or copy it over from Moqui, no problem, the 
license allows it.

I don't think this kind of communication style is very helpful in
general.  This sounds a lot like you are saying to the rest of us “You
are doing it wrong, I know better!”.
I just want to indicate that the OFBiz community is going to run behind 
in the technology developments so from my point of view too conservative.

This is indeed highly desirable to let other interfaces like Single Page
Applications (SPA) consume the data and manipulate the services OFBiz
provides via a RESTlike interface.

On the SPA side, I personally encourage you to look at frameworks based
on what is often referred as the “Elm Architecture” [1] (React/Redux,
Re-agent, Elm, …) for the reason that are based on a “one way data flow”
and embraces functional programming.  They differs from frameworks like
Angular or Vue which has a “two way data-binding” which mean that they
are inherently more complex and harder to reason about.
choosing a use rinterface is an other subject, but not possible without 
a proper rest interface

My advise? If you want to extend the life of OFBiz implement a REST
interface quickly...or copy it over from Moqui, no problem, the
license allows it.

Could you present the design of Moqui REST support (architecture,
advantages, drawbacks, limitations, …) and give some pointers to the
implementation?

Additionally what would be your recommended strategy to port this work?
Are you willing to do the work?

Thanks.

We just support existing OFBiz installations For new installations we 
use Moqui.
I just finished a proof of concept for a native Android/IOS app using 
Moqui REST. For OFBiz i intended to make it work too but that proved to 
be too difficult without REST.


If there would be an OFBiz REST API then it is feasibel to write UI 
applications which both work on OFBiz and Moqui because the basic 
functionality from an API point of view is not that different.


Thanks for your reply..
