Hi,
I don’t know if it is this an off-topic question, however, I think that for an Ionic developer this is a problem that sooner or later has to be addressed.I will develop an app with Ionic and I’m looking for the best back-end to use.
The app will use REST web-service to send and receive data to/from the back-end that will store/retrieve them on/from a database.
On the server side, I need to implement a lot of logic, so I don’t need a framework that just allows me to use a database but a flexible framework that allows me to implement the logic and the algorithms.
The server should manage many simultaneous connections and serve all of them.Until now I’ve always used PHP Frameworks, now I’m evaluating some Javascript framework as NestJS that is based on Node.js.
My doubts are about the ability to manage many connections at the same time because I know that Node.js is a single thread server.
How can it serve tens or hundreds of simoultaneous requests?
The PHP frameworks use Apache, but how can I be sure that Node.js will not be the bottlenec of my system?Thank you very much for your advice.
Claudio

I am working on android application using ionic framework for event which is supposed to run 24hrs on screen. My app is working fine around 15hrs and its started to flickering all of the images and sometime hang. I restarted the device and run application again, only first 10mins-20mins work, rest of the time app becomes flickering. My app is 594.6 MB size big.
Use Case - Showing 5 images and one video as carousel. Every second I’m calling backend API to get the result from Arduino. based on different result, I’ve showed different content.
Phone Spec - OS: Android 9 CPU: Octa-core chipset RAM: 8GB
Thank you so much for helping me out. I don’t know its device problem or my code has issues. Could someone suggest me what is possible reason. Regards.

I don’t want Angular7 in my new Ionic project. Ionic declares that Ionic 4 is framework agnostic, but their CLI seems to be only friendly with Angular7.
I would like to create a project using AngularJS version 1.7.2, compiled with webpack - so I can have the ability to export and import files, and wrapped by cordova so I can bundle it to the AppStores.
However there isn’t any boilerplate under the hood and I started creating a new one but mess with too many things.
I wonder if there any good tutorial making this work the same way I would like?
Furthermore, is there any method to allow using the Ionic CLI with none angular project? for example, on pure JS?

Hey guys,
I’ll be developing quiz-like game application in Ionic, and I have a few questions.
The application should have log-in capabilities, with friend list and of course database of questions.
Which services should I use? I have found this topic Backend for Quiz-App where the answer is to maybe use some PHP frameworks, but to be honest im not to keen with PHP.
What are my other options? Thank you in advance.Kind Regards,

Hello everyone. I’m currently working on mobile app using ionic, but recently I faced an obstacle.
1: Whenever I run the app on browserionic serve --labit runs perfectly.
2:When I run the application on android real device, it can’t open the app and sticks with the first view, and it never vanishes the default spinner, however while I debug the app usingchrome://inspect, there it shows the login page.
I’m gonna provide some screen shots as well.The app is runs on real device, but never shows this (login) page. However on chrome it works perfectly.
This is the spinner page.Here is my app.component.ts file. import { Component, ViewChild } from '@angular/core'; import { Nav, Platform } from 'ionic-angular'; import { StatusBar } from '@ionic-native/status-bar'; import { SplashScreen } from '@ionic-native/splash-screen'; import { Push, PushObject, PushOptions } from '@ionic-native/push'; import { Storage } from '@ionic/storage'; import { App } from 'ionic-angular'; import { HomePage } from '../pages/home/home'; import { ListPage } from '../pages/list/list'; import { AboutPage } from '../pages/about/about'; import { CartPage } from '../pages/cart/cart'; import { timer } from "rxjs/observable/timer"; import { LoginPage } from '../pages/loginPages/loginMainPage/login'; @Component({ templateUrl: 'app.html' }) export class MyApp { @ViewChild(Nav) nav: Nav; rootPage: any = LoginPage; showSplash = true; pages: Array<{ title: string, component: any, icon }>; sendGetRequest() { // ****** Pack the all return in the new promise ****** return new Promise(async (resolve, reject) => { await this.storage.length().then(async (data) => { if (data >= 1) { console.log('There is one data'); await this.storage.get('isLogined').then(value => { console.log('value is', value); // if (value) this.app.getActiveNav().setRoot(LoginPage); } ); this.statusBar.styleDefault(); this.splashScreen.hide(); } }).catch((error) => { console.log('error while accessing isLogined \n' + error); reject(error); }) }); } constructor(private push: Push, public platform: Platform, public statusBar: StatusBar, public splashScreen: SplashScreen, public storage: Storage, public app: App) { console.log('The fist line of constructor '); this.platform.ready().then(async () => { timer(3000).subscribe(async () => { await this.sendGetRequest(); this.showSplash = false; }) }) } ngOnInit() { console.log('ngOnInit'); this.pushSetup(); // used for an example of ngFor and navigation this.pages = [ { title: 'خانه', component: HomePage, icon: 'home' }, { title: 'پروفایل', component: ListPage, icon: 'person' }, { title: 'سبد خرید', component: CartPage, icon: 'cart' }, { title: 'درباره', component: AboutPage, icon: 'person' }, ]; } initializeApp() { this.platform.ready().then(() => { // Okay, so the platform is ready and our plugins are available. // Here you can do any higher level native things you might need. this.statusBar.styleDefault(); this.splashScreen.hide(); timer(3000).subscribe(() => this.showSplash = false) }); } pushSetup() { // to check if we have permission this.push.hasPermission().then((res: any) => { if (res.isEnabled) { console.log('We have permission to send push notifications'); } else { console.log('We do not have permission to send push notifications'); } }); const options: PushOptions = { android: { senderID: "551951714209", }, ios: { alert: 'true', badge: true, sound: 'false' }, }; const pushObject: PushObject = this.push.init(options); pushObject.on('notification').subscribe((notification: any) => console.log('Received a notification', notification)); pushObject.on('registration').subscribe((registration: any) => console.log('Device registered', registration.registrationId)); pushObject.on('error').subscribe(error => console.error('Error with Push plugin', error)); } }Note: let me know if I need to upload more stuffs.

We are deveolping a new app using Ionic/angular 4.x and we are finding several problems related to form validation.
Ionic v4 components are supposed to implement the same behaviour as a vanilla HTML form input field in an angular app. It looks like ionic components try to apply an equivalent ion-*** class for each ng-*** class that angular applies to form elements.
We have verified that in most cases ionic component ion-*** classes are updated correctly at the same time as ng-*** classes when a form value changes. But if you use the angular forms “markAs***” functions to update the status of a form control, ion-*** classes are not updated.
We make heavy use of angular forms in our app and we are finding quite difficult to manage form control styling without using hacky workarrounds.
Is there anyone else experiencing these kind of problems?
