Serialized Error: { code: 'ERR_DLOPEN_FAILED' } with electron-vite and vitest

Hi @murat-dogan

I'm using your package through as a dependency of the libp2p stack.

I'm having the issue below. You can find a reproduction here: https://github.com/MichaelJCole/node-datachannel-reproduction

The issue is:

 FAIL  src/main/test.test.js [ src/main/test.test.js ]
Error: Module did not self-register: '/home/michael/electron-app/node_modules/node-datachannel/build/Release/node_datachannel.node'.

Serialized Error: { code: 'ERR_DLOPEN_FAILED' }

I'm using the module with electron-vite and vitest. When I run vitest, I'm using electron's node like this:

    "test": "ELECTRON_RUN_AS_NODE=1 electron node_modules/.bin/vitest"

npm run test will pass on the first run, but if you hit enter, vitest will run the tests again and fail with the error.

I saw some other similar but different bugs. Is the module's registration re-entrant? Can it run more than once in the same node process?

Thank you!

Hello,

We are using node-addon-api and multiple loading should not be a problem.

I tried the same test with this project https://github.com/julusian/node-jpeg-turbo
It is also using cmake + node-addon-api
I could not regenerate the issue with node-jpeg-turbo.

Then I compared the cmake files and the problem is about CXX_STANDARD. (I don't know the reason)
If you create a hello world module and set the CXX_STANDARD version to 17, then you get the error.

By the way, I can not generate the issue with Jest.
libdatachannel (base lib) is using V17 as standard, so changing is not an option.

I do not have any idea about vite also.

Hi Murat, thank you. I'm not familiar with the tools and this is very helpful. I'll check in with vite and electron.
