Question WebGL - JSlib validation without building

Hi, I wanted to ask if there's any way to "compile" a .jslib file in order to know immediately if there are any syntax errors or some incompatible calls in the javascript code. I don't want to wait the TWENTY minutes needed by the building process just to get informed that I missed a '

(

' or something like that.
I noticed that this is the internal call that compiles the jslib file:

"D:/Development/Programs/Unity/2020.2.1f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten_Win\python\2.7.5.3_64bit\python.exe" -E "D:/Development/Programs/Unity/2020.2.1f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten\emcc" @"<my project>\Temp\emcc_arguments.resp"

I tried to call this command directly through the command prompt but emcc cannot find the correct paths to LLVM and Node.JS... does it need an environement to be configured?

Here's the .resp file that is generated by the building process and that is passed to emcc (I separated arguments in new lines for readability):

I'm also looking for a solution for that.

 

Up.
It's not normal to wait rebuild on every change just to know that there is another mistake.
Maybe someone can tell how to change .jslib zipped inside build without rebuild whole project?

 

Hey Vlad. I was able to modify a jslib without rebuilding the project.

I opened my <buildname>/Build/<buildname>.framework.js.gz file and extracted the framework.js file. The framework file contains a minified version of my jslib. I made the changes I needed, repacked the .gz file and uploaded it. This worked.
