Compiling/linkin works out. I compiled with --preload-file ${CMAKE_CURRENT_SOURCE_DIR}/assets in a CMake project. I do get the js file and the .data file.

I use emscripten in an AudioWorklet scenario.
I would like to preload a set of files to be accessed by the C++ sources.
When loading the file however, I have the following error in the JS Chrome console:
sound-engine.wasm.js:48 Uncaught ReferenceError: XMLHttpRequest is not defined
at fetchRemotePackage (sound-engine.wasm.js:48)
at loadPackage (sound-engine.wasm.js:102)
at sound-engine.wasm.js:196
at sound-engine.wasm.js:198
I am very newb when it comes to web technologies. I wonder if this is because AudioWorklets don't really start in a javascript environment where XMLHttpRequest are available? To be clearer, I'm supposed to load the processor module through this._context.audioWorklet.addModule('./batteur-processor.js'), which in turns imports the WASM file. Maybe this addModule function doesn't provide XMLHttpRequest? Any pointer towards a solution would be appreciated! Thanks!

There are some folks who have been looking into supporting running in AudioWorklet, but AFAIK nothing official has landed yet. If you search for AudioWorklet in the open issues and PRs you should be able to find out more about the current state of play.
@paulfd I guess I had a similar issue. Whether you need to edit filepackeger.py or use -s ASSERTIONS=0 ?
Its described here (at the end of the thread): #12502
And @sbc100 is right, it is not official yet.
You can work around this issue by using --embed-file in place of --preload-file. That will embed the data directly in your .wasm file rather than adding a .data file to load.
Please include the following in your bug report:
