Testing Angular Web components(Custom Elements) with protractor - protractor

When we use the angular custom element tag in the index.html and run our e2e tests using protractor, it causes timeout as angular is not found in the page as for Angular web components there are only entryComponents and no bootstrap component. Because building the angular application for deploying as a custom element doesn't need bootstrapping of component.

To build our angular project for production with customElement and also test the same module in protractor with boostraping the component , below tweak in module bootstrap will work.
#NgModule({
declarations: [AppComponent],
imports: [
BrowserModule,
HttpClientModule
],
providers: [],
entryComponents: [AppComponent]
})
export class AppModule {
constructor(private injector: Injector) {}
ngDoBootstrap(appRef: ApplicationRef): void {
if (environment.production) {
const aboutSystemCustomElement = createCustomElement(AppComponent, { injector: this.injector });
customElements.define('custom-app-component', AppComponent);
} else {
appRef.bootstrap(AppComponent);
}
}
}

Open device settings with Ionic Capacitor

I’m trying to find a way to open the settings/preferences app with capacitor but I’m unsuccessful.
App.canOpenUrl({ url: 'com.apple.Preferences' }) is failing with error message -canOpenURL: failed for URL: "com.apple.Preferences" - error: "Invalid input URL"
I’m not sure if I’m doing it wrong or if it’s even possible with capacitor to open native app…?
this article shows how to open the facebook app, but nothing about native app
There's now a capacitor plugin for this, capacitor native settings.
It's similar to the cordova plugin but you have to call the correct function for each platform (iOS or Android) instead of using a single function for both.
for someone with the same problem
Install:
cordova-open-native-settings
$ npm install cordova-open-native-settings
$ npm install #ionic-native/open-native-settings
$ ionic cap sync
app.module.ts
// ...
import { OpenNativeSettings } from '#ionic-native/open-native-settings/ngx';
#NgModule({
declarations: [
// ...
],
entryComponents: [
// ...
],
imports: [
// ...
],
providers: [
// ...
OpenNativeSettings,
],
bootstrap: [AppComponent]
})
export class AppModule {}
whatever.page.ts
// ...
import { OpenNativeSettings } from '#ionic-native/open-native-settings/ngx';
#Component({
selector: 'app-whatever',
templateUrl: './whatever.page.html',
styleUrls: ['./whatever.page.scss'],
})
export class PopoverComponent implements OnInit {
constructor(
// ...
private nativeSettings: OpenNativeSettings
) { }
phoneSettings() {
this.nativeSettings
.open('settings')
.then( res => {
console.log(res);
})
.catch( err => {
console.log(err);
})
}

'ckeditor' is not a known element Ionic 4

I am working on an Ionic project. I am trying to integrate the CKEditor module on my project.
<ckeditor [(ngModel)]="content" editor="Editor">
</ckeditor>
I am getting an error though:
'ckeditor' is not a known element.
So, I tried some solutions, which I have found on the internet, but unfortunately, nothing worked for me.
I tried including the CUSTOM_ELEMENTS_SCHEMA and NO_ERRORS_SCHEMA. I included the FormsModule, but no chance.
I was wondering, if you could help me, please?
Thank you in advance.
so i solved the problem. I did the following:
var textarea = document.getElementById('editor1');
const ClassicEditor = require( '#ckeditor/ckeditor5-build-classic' );
ClassicEditor.create( document.getElementById( 'editor1' ) )
.then( editor => {
console.log( editor );
} )
.catch( error => {
console.error( error );
} );
install both these packages in your angular or angular-ionic app.
npm install --save #ckeditor/ckeditor5-angular
npm install --save #ckeditor/ckeditor5-build-classic
then import in module app.module.ts, and use it in component.
import * as CKEditor from '#ckeditor/ckeditor5-build-classic';
#Component({
selector: 'app-editor',
template: '<ckeditor [editor]="editor" [data]="summary"></ckeditor>',
styleUrls: ['./edit-summary.component.scss']
})
export class EditorComponent {
summary: string = `<p>Lorem ipsum</p>`
public editor = CKEditor
constructor() {
}
}
If ckeditor is not found then read following:
i.e. you have component summary.component and it is declared in summary.module then it is necessary to import CKEditorModule in summary.module.
let say you have summary.module.ts like:
import { CKEditorModule } from '#ckeditor/ckeditor5-angular';
#NgModule({
declarations: [
SummaryComponent
],
imports: [
CommonModule,
CKEditorModule,
],
exports: [
SummaryComponent
],
})
export class SummaryModule { }
then import CKEditor in summary.component.ts
import * as CKEditor from '#ckeditor/ckeditor5-angular';
#Component({
selector: 'app-edit-summary',
template: '<ckeditor [editor]="editor" [data]="summary"></ckeditor>',
styleUrls: ['./edit-summary.component.scss']
})
export class EditSummaryComponent {
summary: string = `<p>Lorem ipsum</p>`
public editor = CKEditor
constructor() {
}
}

Ionic button showing 'ion-button' is not a known element

I am new to ionic, it seems like a silly question but I need some help
Using some simple button is throwing error. I am using ionic 4.0.
'ion-button' is not a known element:
1. If 'ion-button' is an Angular component, then verify that it is part of this module.
2. If 'ion-button' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '#NgModule.schemas' of this component to suppress this message.
<ion-button color="primary">Primary</ion-button>
I think the solution is importing Ionic module in the respective module imports
import { IonicModule } from '#ionic/angular'; <--add this line
#NgModule({
imports: [
CommonModule,
FormsModule,
IonicModule, <-- add this line
],
})
Try this,
<button ion-button color="primary">Primary</button>
In order to avoid that error message:
Import CUSTOM_ELEMENTS_SCHEMA into app.modules.ts:
import { ErrorHandler, NgModule, CUSTOM_ELEMENTS_SCHEMA } from '#angular/core';
Add schema: [CUSTOM_ELEMENTS_SCHEMA] to app.modules.ts as below:
#NgModule({
declarations: [
MyApp,
HomePage
],
imports: [
BrowserModule,
HttpClientModule,
MomentModule,
IonicModule.forRoot(MyApp),
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler},
],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
I've run into this too. Your solution is not the best one as the new Ionic 4 way is to use <ion-button> (https://beta.ionicframework.com/docs/components/#button).
It does work for me fine in a page I have under /src/app/my-page/my-page.html, but when I put it in /src/shared/components/my-comp/my-comp.html it gives the error. The odd thing is that I have other Ionic elements in the same page <ion-grid>, <ion-row> and <ion-col>. Also, this code used to be in my-page.html where it worked without error.
FYI, MyComponent is in components.module.ts as a declaration and an export. Not sure yet what I am missing...
UPDATE 1: Neither moving the components directory under src nor under src/app made any difference.
UPDATE 2: This is my environment:
ionic (Ionic CLI) : 4.0.6
Ionic Framework : #ionic/angular 4.0.0-beta.2
#angular-devkit/core : 0.7.2
#angular-devkit/schematics : 0.7.2
#angular/cli : 6.1.2
#ionic/ng-toolkit : 1.0.0
#ionic/schematics-angular : 1.0.1
UPDATE 3: Still broken in this environment:
ionic (Ionic CLI) : 4.1.0
Ionic Framework : #ionic/angular 4.0.0-beta.3
#angular-devkit/core : 0.7.2
#angular-devkit/schematics : 0.7.2
#angular/cli : 6.1.2
#ionic/ng-toolkit : 1.0.6
#ionic/schematics-angular : 1.0.5
UPDATE 4: After much trial and error, I had to add schemas: [CUSTOM_ELEMENTS_SCHEMA] to my components.module.ts file. I was able to leave the directory structure as-is. I'm not sure why this is required for this scenario, though.
It seems you are not importing the ionicModule in the component module. So, Import the IonicModulein the module.ts, rest of the things will work fine
Import your custom component in the parent module. for example in your app.module.ts:
declarations: [MyComponent],
exports: [
PopoverComponent,
]
yes try this
<button ion-button color="primary">Primary</button>
In Ionic 5, I have a same problem when I build with --prod option.
Since *.module.ts file is not available in components in Ionic 5, I need to add shared module for components and then add CUSTOM_ELEMENTS_SCHEMA schema to that shared module.
ionic g module modules/shared
cat shared.module
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '#angular/core';
import { CommonModule } from '#angular/common';
import { FooComponent } from '../../components/foo/foocomponent.component'; <== Add your components
#NgModule({
declarations: [FooComponent], <== Add your components
imports: [
CommonModule
],
exports: [FooComponent], <== Add your components
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class SharedModule { }
I was having this problem in a library that I was building
because I forgot to export the module of that was importing the IonicModule and exporting my component.
So, in my module was importing Ionic lib and exporting my component as below.
import { CommonModule } from '#angular/common';
import { NgModule } from '#angular/core';
import { IonicModule } from '#ionic/angular';
import { MyComponent } from './my.component';
#NgModule({
declarations: [
MyComponent,
],
imports: [
CommonModule,
IonicModule,
],
exports: [
MyComponent,
],
})
export class MyModule {
}
And in the public-api.ts file of my lib, I should have something like this
export { MyModule } from './lib/my.module'; // <--- exporting my module
export { MyComponent } from './lib/my.component';
My issue was that there were errors prior to this error that seemed to cascade down. The error I had was some elements in the declarations that should have been in the providers. Also, one of these was marked private in the constructor when it should have been public.
#NgModule({
imports: [
IonicModule,
CommonModule,
FormsModule,
RouterModule.forChild([{ path: '', component: DevicesPage }]),
DevicesPageRoutingModule,
TranslateModule.forChild()
],
declarations: [DevicesPage --> remove BLE, LocationAccuracy, DeviceManagerService ],
providers: [BLE, LocationAccuracy, DeviceManagerService] <--Add
})
I was stuck on this for a little while as well until I realized that the problem was I did not create the Ionic Angular project properly. you have to include --type=angular
https://github.com/ionic-team/ionic-cli
exp:
ionic start myApp tabs --type=angular
I faced similar issue after ionic 4, So I added the CUSTOM_ELEMENTS_SCHEMA in app.modules.ts. Then it worked fine
app.module.ts
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler},
SpineRestServiceProvider,
FingerprintAIO
],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
Should add in app.module.ts
import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '#angular/core';
providers: [
StatusBar,
SplashScreen,
{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
],
schemas: [CUSTOM_ELEMENTS_SCHEMA] ==> add line**

Ionic, The pipe 'translate' could not be found, only in AoT Compiler

I have a problem with ngx-translate within a Ionic App when I try to build a production release.
During development translations work fine with
ionic serve
and
ionic cordova build android
but if I try to make a production build using
ionic cordova build android --prod --release
or for the PWA
ionic build --prod
I get some errors like
[17:47:15] typescript error
The pipe 'translate' could not be found ( ... )
Versions:
ngx-translate: 8.0.0
Ionic: 3.9.2
Angular: 5.2.10
I checked with: https://github.com/ngx-translate/core/tree/v8.0.0 and can't find what I am doing wrong.
In app.module:
// https://github.com/ngx-translate/core#1-import-the-translatemodule
// AoT requires an exported function for factories
export function createTranslateLoader(http: Http) {
return new TranslateHttpLoader( http, './assets/i18n/', '.json' );
}
#NgModule( {
...
imports: [
...
TranslateModule.forRoot( {
loader: {
provide: TranslateLoader,
useFactory: (createTranslateLoader),
deps: [ Http ]
}
}
),
...
And in one of my pages which produce this error:
import { TranslateModule, TranslateService, TranslatePipe } from '#ngx-translate/core';
#NgModule({
imports: [
TranslateModule
],
exports: [
TranslateModule
]
})
export class ContactPage { ... }
Searching through SO produced mainly the hint to import & export the TranslateModule in the page as well as importing the TranslatePipe, but both of these changes didn't solve my problem. How do I configure the translation module so that it works in a production build?
OK, solved it. I added the import & export statement of the TranslateModule to the page class, but correct is to add it the the corresponding module.
In my example:
Wrong:
contact.ts
#NgModule({
imports: [
TranslateModule
],
exports: [
TranslateModule
]
})
export class ContactsPage {...}
Correct:
contact.module.ts
#NgModule( {
...
imports : [
...
TranslateModule
],
exports : [
TranslateModule
]
} )
export class ContactsPageModule {
}

Getting Angular2 error 'No provider for Router! (RouterOutlet -> Router)'

I use Angular2 alpha39 and Babel to transpile the ES6 JS file. I'm not using typescript.
I created a component which displays correctly. I added a router-outlet to the template. When I run the app, I get the error message:
No provider for Router! (RouterOutlet -> Router)
The call stack is:
Here is the snippet of code:
template:
.... // Removed for brevity
<div class="contenttext">
<router-outlet></router-outlet>
</div>
.... // Removed for brevity
Component file:
import { Component, View, bootstrap, OnInit } from 'angular2/angular2';
import { RouteConfig, RouterOutlet, RouterLink } from 'angular2/router';
import 'reflect-metadata';
import 'winjs';
#Component({
selector: 'dashboard-app'
})
#View({
templateUrl: '../js/dashboard.html',
directives: [ ContentComponent, FamiliesComponent, RouterOutlet, RouterLink ]
})
#RouteConfig([
{ path: '/employees', component: EmployeesComponent, as: 'employees'}
])
class DashboardAppComponent implements OnInit {
constructor() {
}
onInit() {
WinJS.UI.processAll().done(function() {
var splitView = document.querySelector(".splitView").winControl;
new WinJS.UI._WinKeyboard(splitView.paneElement);
})
}
}
bootstrap(DashboardAppComponent);
you have to use:
ROUTER_BINDINGS in your bootstrap.
in your index.html.
if possible use state i.e as "employees" in capitalize i.r as "Employees". (in alpha 42 i have solve one problem this way).
i hope this will surely help you.
--UPDATE--
after the relese of alpha41:
ROUTER_BINDINGS has been changed with ROUTER_PROVIDERS .
Router Aliases should be in the camel case manner.
for the Router-outler and router-link you just have to import ROUTER_DIRECTIVES in your directives property in the component annotation.
Router-link expects the value to be an array of route names. for more info. refer here .
for more info regarding Routing you may refer to this tutorial here .
---Update2---
Now ( as of alpha-49) router is exported as ng.router.
(According to alpha-47 all life cycle hooks renamed as.)
onActivate, onReuse, onDeactivate, canReuse, canDeactivate
To :--
routerOnActivate,routerOnReuse,routerOnDeactivate,routerCanReuse,routerCanDeactivate
---Update3---
router-link is changed to routerLink
and routeconfig property changed to:
{path: '/abc', component: ABC, as: 'abc'}
to:
{path: '/xyz' , component: XYZ, name: 'xyz'}
--Update 4 --
UPDATE TO ANGULAR2 RC
There are alot of changes has been made in routing in angular2 after RC some of them points i am going to mention here may help someone :-
angular2/router has been changed with #angular/router
(also you can use old functionality of routing using import of #angular/router-deprecated but as of now we have to use #angular/router).
#RouteConfig has been changed with #Routes .
for example :-
#Routes([
{path: '/crisis-center', component: CrisisListComponent},
{path: '/heroes', component: HeroListComponent}
])
2.0.0-alpha.36 (2015-08-31)
routerInjectables was renamed to ROUTER_BINDINGS
2.0.0-alpha.41 (2015-10-13)
ROUTER_BINDINGS was renamed to ROUTER_PROVIDERS
USE ROUTER_PROVIDERS
ROUTER_PROVIDERS is used to simplify bootstrapping the router.
It includes:
RouterRegistry - the collection of registered routes
LocationStrategy = PathLocationStrategy - match by path
ROUTER_PROVIDERS provides 'sane' defaults and should be used unless you need to need a different route LocationStrategy.
Change:
bootstrap(DashboardAppComponent);
To:
bootstrap(DashboardAppComponent, [
ROUTER_PROVIDERS
]);
Sources:
angular/commit/ccfadb9
angular/pr#4654
2.0.0-alpha.38 (2015-10-03)
Route aliases need to be CamelCase (technically PascalCase)
Note: this was mentioned already in Pardeep's answer under #3
If you want to include a link to a route in your template via router-link you have to make sure the alias (ie the name property) of the route is PascalCase.
If you use plan to use router-link modify the route to:
{ path: '/employees', component: EmployeesComponent, name: 'Employees'}
Then you can add the link in your template with:
<a [router-link]="['/Employees']">Employees Link</a>
RouterLink dynamically inserts a href that matches the route path.
Note: Reading the issue/pr it appears this change was made to prevent users from confusing the <route-link> binding with the route url

Tip:
If you want to simplify your view directives use ROUTER_DIRECTIVES
It includes:
RouterLink
RouterOutlet
Update:
In the near future, RouterOutlet/<router-outlet> will be renamed to RouterViewport/<router-viewport>
Source:
angular/issues#4679
Update 2:
The RouteConfig property as has been renamed to name

Answer on Dec 23rd 2016 (Angular v2.4.1, Router v3.4.1 - should work for any NG v2.x.x + Router v3.x.x)
I just migrated three of our apps from the Webpack Starter Seed to Angular CLI (v1.0.0-beta.24) and hit this issue.
Only a tiny fraction of what's on the NG 2 massive router doc page is required:
An app-routing.module.ts file (typically in src/app/ folder) looking like this sample:
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
const appRoutes: Routes = [
{ path: '', component: YourHomePageComponent },
{ path: 'next-page', component: NextComponent }
];
#NgModule({
imports: [
RouterModule.forRoot(appRoutes)
],
exports: [
RouterModule
]
})
export class AppRoutingModule {}
Import AppRoutingModule into your main module (typically src/app/app.module.ts):
#NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
AppRoutingModule // <--- The import you need to add
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Ensure you have <router-outlet></router-outlet> somewhere in your main html (often src/app/app.component.html) as this is where router content is injected.
Make sure you have router defined and declared in AppModule.
Example (look everywhere where routing is mentioned, ignore the rest):
app.routing.ts
import { ModuleWithProviders } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { HeroesComponent } from './heroes.component';
import {DashboardComponent} from './dashboard.component';
import {HeroDetailComponent} from './hero-detail.component';
const appRoutes: Routes = [
{
path: 'heroes',
component: HeroesComponent
},
{
path: 'dashboard',
component: DashboardComponent
},
{
path: '',
redirectTo: '/dashboard',
pathMatch: 'full'
},
{
path: 'detail/:id',
component: HeroDetailComponent
},
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);
and app.module.ts:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
// Imports for loading & configuring the in-memory web api
import { InMemoryWebApiModule } from 'angular-in-memory-web-api';
import { AppComponent } from './app.component';
import { DashboardComponent } from './dashboard.component';
import { HeroesComponent } from './heroes.component';
import { HeroDetailComponent } from './hero-detail.component';
import { HeroService } from './hero.service';
import { routing } from './app.routing';
import './rxjs-extensions';
import {HeroSearchComponent} from './hero-search.component';
#NgModule({
imports: [
BrowserModule,
FormsModule,
HttpModule,
routing
],
declarations: [
AppComponent,
DashboardComponent,
HeroDetailComponent,
HeroesComponent,
HeroSearchComponent
],
providers: [
HeroService,
],
bootstrap: [ AppComponent ]
})
export class AppModule {
}
This can save someone an hour:
You get this error if you don't even use routing (for example temporary, maybe you don't import routing config and router-outlet is commented out) BUT you are using Router or ActivatedRoute in some component constructor via dependency injection, like this:
#Component({...}})
export class SomeComponent {
constructor(private _router: Router, private _route: ActivatedRoute) {
//may be you are not using _route/_route at the moment at all!
}
...
}
You cant user Dependency Injection for Router if you dont define any routs!
To define route user something similar to following codes:
const loginRoutes: Routes = [
{path: 'foo/bar/baz', component: 'MyRootComponent'}
];
#NgModule({
imports: [
BrowserModule,
FormsModule,
HttpModule,
JsonpModule,
RouterModule.forRoot(loginRoutes)
],
providers: [],
declarations: [
MyLoginComponent
],
bootstrap: [
MyLoginComponent
]
})
export class MyLoginModule
{
}
