Client side in browser compiling and rendering

Both compilation and rendering are made in the browser: templates can be authored directly in the browser, or dynamically generated, compiled in the browser and the texts can also be rendered in the browser.

To be able to do that, you must use a js version of RosaeNLG that is larger, with comp at the end, like rosaenlg_tiny_fr_FR*_comp.js:

  • it includes the templates compiler

  • but also all linguistic resources that are associated with a language

Client side compilation is for exotic usecases. You should favor server side compilation.

It can be used to create a 100% client side editor and renderer, like in this demo.

Works with Firefox and Edge, but not with older IE.

Well, the German version with compilation support is too large indeed.
