Please, tell us how to recreate the issue in as much detail as possible.

Import Feathers socket io client on one of your pages:

import socketio from '@feathersjs/socketio-client';

And run tns build android

You will get this error:

ERROR in ../node_modules/debug/src/node.js
Module not found: Error: Can't resolve 'net' in '/home/sullivan/p/github.com/soullivaneuh/svelte-native-test/node_modules/debug/src'

 @ ./app.ts

It's maybe FeathersJS related only, but I'm not sure and would like to know what you, native expert, thing about this issue.

Is there any code involved?

Here is a PR coming from a fresh svelte-native template: https://github.com/soullivaneuh/svelte-native-test/pull/2

If I install the net package and run tns run android (not build), now I get:

System.err: TypeError: Cannot read property 'env' of undefined
System.err:     at com.tns.Runtime.runModule(Native Method)
System.err:     at com.tns.Runtime.runModule(Runtime.java:674)
System.err:     at com.tns.Runtime.run(Runtime.java:666)

System.err:     at android.app.ActivityThread.handleBindApplication(ActivityThread.java:5740)
System.err:     ... 8 more

And the error is gone if I remove the import.

I'm not sure I have to install the net module by the way, I don't have to on web dev.

I also opened feathersjs/feathers#1843, I'm not very sure what should be fixed here.

@soullivaneuh did the suggested fix resolve your issue?

I think it would be something like this:

import feathers from '@feathersjs/client'
import feathersSocketIO from '@feathersjs/socketio-client'

var SocketIO = require('nativescript-socketio').SocketIO;
var socket = new SocketIO('http://localhost:3030', { transports: ['websocket'] })

// let hasConnectedOnce = false
const feathersClient = feathers()
  .configure(feathersSocketIO(socket))
