Re: GWT + Open API

Thanks, Rogelio, for your instructions.

I'm working on this now.  I'll report on the progress later.

No, I have not tried generating API interfaces for a CXF client. I
don't remember even seeing that option when we first created the api
(more than a year ago). I might try that out.

To create our GWT "Models" module, we simply add a gwt module file
with these 3 lines:

|


   



|

to the generated Java source code, package it into a jar file, and we
can import and use that module on any GWT app (and also on the server
side along with the rest of the generated files, so we can call the
same api programmatically).

Our API is externally available (to customers that buy our enterprise
product) so that customers can request/manipulate the data with their
own RESTful clients if they choose to.

I like the idea of generating the data model from the OpenAPI
specification, because I will not have to write some boring
error-prone code.  I also like the optimization of the GWT compiler.

The swagger-codegen can output Jaxrs Cxf Client, which has the API
interface defined with JAX-RS annotations.  So it seems that even the
interfaces could be auto-generated.  You only have to modify them so
that they extend RestService, required by RestyGWT.

Have you tried auto-generating the API interfaces with Jaxrs Cxf
Client?

In your previous message you wrote that you auto-generate a GWT
module.  What do you specifically mean by a module here?  Do you use
some publicly-available tools, or do you have something home-grown?

No :), just to see the complexity of the API and what happens if I add it

GWT gwt obfuscation (gwt-style=OBF) generates invalid css

2017-03-25 Thread Hannes 
I compile my gwt project with gwt-style=OBF. Now I realize that this 
generates media queries where the space between "and" and "(" is missing. 
So out of 

@media screen and ( ... gets 
@media screen and(

As you can see the space between "and"  and "(" is missing.
According to W3C this not ok and 
also does not work (at least in chrome and firefox). 
You can easily test this in chrome by adding a @media query for example in 
chrome by adding a rule to the inspector style sheet as desribed here 
.
 
You will see that adding the space between "and" and "(" changes 
everything! :-)


Do you have any idea how to generate working css and still use gwt 
code obfuscation?

Thanks in advance
Hannes
