Attempting to require a nodejs addon causes the app to crash

[coreyphillips]

• Project: nodejs-mobile-react-native
• Version: 0.6.1
• Mobile device: iPhone 11 Simulator
• Mobile OS and version: iOS Simulator Version 11.6 (921.9.1)
• Development Node.js: v10.15.1
• Development platform: Darwin 19.5.0 Darwin Kernel Version 19.5.0: RELEASE_X86_64 x86_64

Has anyone else had any luck utilizing a .node nodejs addon with nodejs-mobile-react-native? Attempting to require the .node file appears to crash the app.

I created a project here that should reproduce the error and crash the app once the try/catch is removed from the main.js file here.

It turns out the errors I'm receiving are the following:

iOS:
Error: dlopen(/private/var/containers/Bundle/Application/ED3FDD4B-524A-4C81-9489-AA3033180524/nodeAddonAttempt.app/nodejs-project/rgb_node.node, 0x0001): could not use '/private/var/containers/Bundle/Application/ED3FDD4B-524A-4C81-9489-AA3033180524/nodeAddonAttempt.app/nodejs-project/rgb_node.node' because it is not a compatible arch

Android:
Error: dlopen failed: \"/data/data/com.nodeAddonAttempt/files/nodejs-project/rgb_node.node\" has bad ELF magic: cffaedfe

Possibly an issue with how the nodejs addon is built? If so, how would I include the mobile architechtures into the addon for use in nodejs-mobile-react-native?

Hi @coreyphillips ,
This looks like the native module is not built for Android and/or iOS (the .node file here.
The react-native-module has a way to rebuild native modules when the .gyp and source files are inside node_modules when you are building the application, by setting the right environment variables to use the nodejs-mobile headers, use nodejs-mobile-gyp, set the right architectures and so on.
