Create a new component withionic g c list-user 

import { Component, OnInit } from '@angular/core';

    @Component({
  selector: 'app-list-user',
  templateUrl: './list-user.component.html',
  styleUrls: ['./list-user.component.scss'],
})
export class ListUserComponent implements OnInit {

  constructor() { }

And this is the file app.module.ts

import { ListUser } from './list-user/list-user.component';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent, ListUser],


  ngOnInit() {}

}

This is the error I get:

compiler.js:2430 Uncaught Error: Unexpected value 'undefined' declared by the module 'AppModule'
    at syntaxError (compiler.js:2430)

I want to make an app with ionicand expressjs, but I get this error:

This is the git of the project: https://github.com/hubmanS/GameStix

to raise the backend with nodemon serverand the frontend withionic server

I have this in app.jsthe expressjs.

var app = express();

const cors = require('cors');
app.use(cors());
app.options('*', cors());


var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', 'http://localhost:8100');
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    res.header('Access-Control-Allow-Headers', 'Content-Type');

    next();
}


app.use(allowCrossDomain);
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());

app.use(express.static(path.join(__dirname, 'public')));

app.use('/', indexRouter);
app.use('/users', usersRouter);

and from ionicI want to call backend.

constructor(public http: HttpClient) {
        super(http);
        this.http.get(`http://localhost:3000/customers/`);    
         console.log('MENSAJE', this.http.get(`http://localhost:3000/customers`));
    }

You are supposed to enter this router.

router.get('/customers', function(req, res, next) {
    console.log('NOMAS');
  res.render('index', { title: 'Express' });
});

but the console.

I am making an App in Ionic.

At one point in the App I need to press a button and close the current page I am on.

I do it in the following way:

  • This is how I declare the button in the HTML view:

<button ion-button full (click)="guardarNuevoPerfil()">Guardar Perfil</button>

and this is the saveNewProfile() method of the Typescript part:

this.storage.get('listadoPerfiles').then((perfiles) => {
    //Aquí guardo el perfil, justo despues necesito cerrar la página actual

    window.close();  //No funciona
    self.close();    //No funciona
});

As you can see in the code, I've tried window.close() and seslf.close() but it doesn't do anything, it doesn't close the tab.

This is the behavior I want to have:

desired behavior

I have searched in google and nothing has come up, practically everything that comes out in for Javascript.

I am trying to use a TCP connected socket in my Ionic 3 app.

To do this I follow the following steps:

1- I create an ionic app:

ionic start testTcp blank --cordova

2- I enter the application directory

cd testtcp

3- I install ionic-native (when creating the project I think it already includes it but I still install it again)

npm install ionic-native --save

4- I download the following plugin to install it from local instead of installing it from the repository, the downloaded plugin is the following: https://github.com/KoenLav/cordova-plugin-chrome-apps-sockets-tcp

5- I install the plugin in my application:

ionic cordova plugin add cordova-plugin-chrome-apps-sockets-tcp-master

So far everything is going well, if I look at the plugins that I have installed with the following command: ionic cordova plugin lsit tells me that I have the plugin "cordova-plugin-..." installed, which is the one that I just installed.

The problem comes when using this plugin, when creating a socket and connecting to a host.

How do I use this plugin? Do I have to do an import in the home.ts file? How would this import?

Being an own plugin I don't see how to do it and I can't find documentation.

I've tried the tool plugmanbut it won't even let me install the plugin.
