描述

Hi there,

Here is a feature request:

I am working on a NodeJS application, which starts up a relatively large Emscripten / WASM project, which uses several dynamically linked libraries (via the dynamicLibraries entry in the Module object). Currently, startup of the application takes several minutes. To speed things up, I imagine it would be very helpful to use NODE_CODE_CACHING=1. However, this only seems to work with the MAIN_MODULE (I get a *.cache.xxxxx file only for that type of module) and not with any SIDE_MODULE (there are no *.cache.xxxxx files).
