Hi there,

I’ve been stuck at this issue with @ionic-native/network plugin for days and I’m unable to find a solution. I’m relatively new with Ionic, so excuse my code.

This is my Ionic info:

I’ve imported the network module like this:

import {Network} from '@ionic-native/network';

The error I get is:

TS2749: 'Network' refers to a 'value', but it's being used as a 'type' here.

in
constructor(private network: Network, private toastController: ToastController, private plt: Platform)

Also when I adding the module to providers in app.module the error I get is:

TS2332: Type 'NetworkOriginal' is not assignable to type 'Provider'.

I read online that that’s due to the version of the package I’m using, so I tried to update to the latest version of @ionic-native/network as well and then import like this:

import {Network} from '@ionic-native/network/ngx';

That clears those errors and I can include it as a provider and also add it to constructor as a typeprivate network: Network, however when I try to use it like this:

this.network.onDisconnect().subscribe(() => {
            if (this.status.getValue() === ConnectionStatus.Online) {
                console.log('WE ARE OFFLINE');
                this.updateNetworkStatus(ConnectionStatus.Offline);
            }
        });

I get this error:

I’m really not sure what to do. I appreciate your help.

If this is a new app, I would strongly recommend upgrading all dependencies to most recent versions. The easiest way to do this would probably be to start a completely new app, and then parachute your old code into it.

The proximate cause of the problem you are seeing is a side-effect of ionic-native support for frameworks other than Angular, which was added in major version 5 of ionic-native. When you upgraded @ionic-native/network to current (5.13.0 as I write this), the trailing “/ngx” is indeed desired in the import (to say “I am using Angular”), but the companion package @ionic-native/core is still sitting on major version 4, hence the Object(...) is not a function problem. Bringing @ionic-native/core up to version 5 will fix that as well, but as long as you’re doing that, I again suggest biting the bullet and upgrading all your other dependencies as well.
