I think it’s something that should come eventually if you guys move towards ES modules, which I am guessing you will at some point in time.
Also I think the Theme Manager could get some refactoring and move from Wappler’s custom json implementation to using a CSS pre-processor implementation(SASS, LESS, Stylus, etc). That way we could throw in a 3rd party theme and the Theme manager could pick up all the variables, mixins, etc.
I personally don’t use the Theme Manager because it kind of locks you in Wappler json format to build the themes. If it were based on standards it would be more in line with Wappler’s philosophy. Right now it’s kind of a deviation.
If wappler used pre-processors Vite would be useful too.
TS out-of-the-box support is also a plus. I wouldn’t mind writing extensions in TS.
Is something like Vite needed now? As you mention, not at all. But if Wappler evolves following current development trends I guess it’s a must.
