Create your own viewrender

But you can also write your own 'ForceViewRender' implementation as follow. This is not needed when you are happy with the mustacheRender engine!

class FancyRender extends ForceViewRender {
  
  FancyRender(ServingAssistent servingAssistent, [views = "../views/", clientFiles = "../build/web/", clientServe = true]) : super(servingAssistent, views, clientFiles, clientServe);
  
  String _render_impl(String template, model) {
    // render logic of your template + model will become your output
    return fancy_render(template, model);
  }
}

And register your FancyRender as a component as follow:

@Config
class OwnConfig {
  
  @Autowired
  ServingAssistent servingAssistent;
  
  @Bean
  ForceViewRender viewRender() {
     return new FancyRender(servingAssistent);
  }
  
}
