Why do you need to convert it to javascript? D can serve up web 
stuff by itself too.

did you mean vibe.d?

but i want to use in a shared hosting environment where my 
options are : ruby, python, nodejs and as usual php

vibe.d as standalone app will not work.

i know kotlin with js support, but maybe there is another option 
..


thanks for your answer and insight.

I haven't personally tried it, but there is an example of 
compiling D to Javascript here :

The example I used (thanks to Cosinuns): 
https://github.com/cosinus2/dlang-emscripten-demo

I'd try DScripten first, though. Without, I need to compile parts 
of Phobos myself to JS. Plus the Emscripten linker seemingly 
can't link D symbols because of some bug.

I have to manually call the LLVM linker, which sometimes seems to 
have different ideas about what the program is calling.

Let me recommend https://bridge.net/



using JavaScript directly.

Minority of my JavaScript is also transpiled from D. If you do 
the same, you will need a lot more determination and know-how 
than normal, and you can't except to use all D features. 
Multithearding and GC among other features are out.

You could use DScripten which will probably make D better in this 
regard, but still not like normal. Personally I haven't still 
tried DScripten because there is not much I could easily port to 
D.

The reason for that is that D cannot call most js functions 
directly, because it cannot handle most JavaScript types. Except 
if you manage to translate Emscripten headers val.h and wire.h 
(which are heavily templated c++) into D. I have put some effort 
to that, but it's not going well.

Because of the reasoms above, I don't currently recommend D as a 
JavaScript source for the average programmer. However, you will 
most likely want to make some utility programs to assist you 
-build scripts, mass file handling, translating configuration 
file formats etc. There D works very well.

Also, as said, the server backend does not have to be JavaScript 
- only the frontend. For backend, you can use D web frameworks 
-vibe.d/hunt/diamond- instead.
