How are these .env files normally used?
I think they are not part of core Node.js.
If they are used through a module I suppose trying those modules would be the way to go.
You might also be able to use the native way for setting enviroment variables on each platform.
That could be interesting, but users seem to expect that the V8 engine is used underneath. Before we used to have chakracore on iOS and it was requested that V8 was used for iOS as well, with the expectation that this would make modules that you'd use on a server part of the code more compatible with mobile code.
The current plan is to keep using official Node.js as the base repo, for better future compatibility with modules.
There's also some effort put into having the engine start as soon as possible, as app load times were a concern in earlier versions, and the official Node.js - V8 pairing seems to do a good job at this.
What benefits would you say switching to graal brings?
Anyway, should you be able to build a libnode.so and a set of compatible headers for native modules, I suppose those could be used interchangeably with current binaries.
nodejs-mobile now uses V8 in both Android and iOS.
There are no plans for bitcode on iOS currently.
This would be a welcome contribution, though.
I have been using nodejs-mobile in S8 Smalltalk platform running on android devices witgout any problems for long time.
Recently I implemented tello dhrone interface that uses dgram socket (client & server) to connect to the dhrone and listen for results and data.
The code works OK running on top of node.js on windows desktop; but when I run the same on nodejs-mobile, the (upd4) socket instances are created and bound but NO message is received and also no error report.
Does someone know a reason why it can happen running in the android device?
Any recommendation or guidance to find the issue will be realy appreciated.
kind regards,
react-native run-android. The error isFAILURE: Build failed with an exception.What went wrong:Execution failed for task ':nodejs-mobile-react-native:MakeToolchainarm64-v8a'.> Process 'command '/home/manul/Android/android-ndk-r21b/build/tools/make-standalone-toolchain.sh'' finished with non-zero exit value 1
Hello everyone! I am a Java Android application developer and I decided to learn React-Native. However, I have a problem.
https://ibb.co/JcsXgCb
When I run the command nodejs.start ('main.js') in the image above, my react-native app closes (in android emu.), I cannot learn what I did wrong because the application closes without giving me any type of error output...
I would be glad if you help me!
Thank you!

I fixed this issue with downgrading react-native version from latest to 0.61.5, have a nice holiday!
Hello, I have been running my app successfully in node on Termux. However, with nodejs-mobile it crashes with the message
E/nodejs: os.js:63
throw new ERR_SYSTEM_ERROR(ctx);
^
SystemError [ERR_SYSTEM_ERROR]: A system error occurred: uv_interface_addresses returned Unknown system error 13 (Unknown system error 13)
at Object.networkInterfaces (os.js:205:16)
the node version on Termux is newer than the one in nodejs-mobile, so I'm not sure if the problem will disappear when node 14.4. comes to nodejs-mobile. But any suggestion on how to address this issue would be very welcome!

I'm facing the same Problem as @Retog a while ago. Does anybody have an idea how to solve this?

@jaimecbernardo Hi, My app just failed with the following error:
Fatal error in , line 0
API fatal error handler returned after process out of memory
#
in a mobile environment, the solution below does not work as there are no user settable environment variables/file
export NODE_OPTIONS=--max_old_space_size=4096
Would calling node with the command line (from my MainActivity.java) work?
startNodeWithArguments(new String[]{"node","--max-old-space-size=4096", nodeDir+"/main.js"});
The good news is that adding to the argument list for startNodeWithArguments works (at least it appears to work).
I would still like confirmation from @jaimecbernardo that chaning the startNodeWithArguments argument list does work.
Thanks for your help

Hi, I'm trying to get native node modules to work with my Corova Project, but currently I'm failing badly. I see there are a few Issues for this and i opend up one myself.
Has anyone a working setup to cross compile node modules that have native code like the sqlite3 module?
Anyone had issues with bundling sqlite3? node-sqlite3 yarn add sqlite3
@semidark sounds like you are trying todo the same thing?
So the app has been working like this now for over a year. and since I updated to use the new API keys to upload to appstore connect it appears to be more restrictive in the upload?
"Invalid Bundle Structure - The binary file 'myapp.app/nodejs-project/node_modules/sqlite3/lib/binding/node_abi-platform-arch/node_sqlite3.node' is not permitted. Your app can’t contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at https://developer.apple.com/go/?id=bundle-structure for information on the iOS app bundle structure."
Yeah, trying to do a similar thing on Android but failing even to build the .node files. I think the .node files are the cross compiled binaries that nodejs-mobile library loads. I guess you cant remove them without loosing the functionality of the the node package.
I was thinking about using a wasm version of the sqlite code, so i don't need to crosscompile the c++ code. Since I don't need sqlite that badly, this was just an Idea for the future: https://www.npmjs.com/package/sqlite-wasm
bcrypto@5.4.0 install:node-gyp rebuild`` whenever i build in xcode. please let me know if anyone knows whats going on with this.
I've been a bit more absent indeed.
I don't think I ever trying to get ipfs or bcrypto working myself.
@export-mike , .node is a shared library, which will be detected and rejected by Apple. the method for dynamic libraries in the plugins should be trying to convert to a framework and deleting every .node when building. Not sure why you're still seeing .node files.
These scripts are in the plugin's
./scripts path and use nodejs-mobile-gyp, which is capable of building .frameworks: https://github.com/JaneaSystems/nodejs-mobile-react-native/blob/17fe8f26b6d253b2eec648efcf086aaae0cbc078/scripts/ios-build-native-modules.sh#L39-L43
