I want to use InAppBrowser to open all target blank links. I follow the documentation and I always get an error when I declare the plugin on constructor:
Can't resolve all parameters for MyApp: (?, ?, ?).
This error appears to me when I put private iab: InAppBrowser on constructor.
My code:
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import { InAppBrowser } from '#ionic-native/in-app-browser';
import { Platform } from 'ionic-angular';
#Component({
selector: 'page-home',
templateUrl: 'home.html',
})
export class HomePage {
constructor(public navCtrl: NavController, public plt: Platform, private iab: InAppBrowser) {
this.plt.ready().then((readySource) => {
console.log("Ready!");
window.open = this.iab.open;
});
}
app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { ErrorHandler, NgModule } from '#angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '#ionic-native/splash-screen';
import { StatusBar } from '#ionic-native/status-bar';
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { InAppBrowser } from '#ionic-native/in-app-browser';
#NgModule({
declarations: [
MyApp,
HomePage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage
],
providers: [
StatusBar,
SplashScreen,
InAppBrowser,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
Someone knows whats it can be?
Thanks!
Your code looks good, so the problem seems to be because of the #ionic-native/core version that your project uses.
As you can see in the docs the Ionic team has updated the Ionic Native commands in order to avoid this error:
Installation
To add Ionic Native to your app, run following command to install the core package:
npm install #ionic-native/core#4 --save
And...
Usage
Install the Needed Plugins
Install the Ionic Native package for each plugin you want to add.
For example, if you want to install the Camera plugin, you will need to run the following command:
npm install #ionic-native/camera#4 --save
Then install the plugin using Cordova or Ionic CLI. For example:
ionic cordova plugin add cordova-plugin-camera
Notice the #4 in both commands. That allows you to install the right version of the Ionic Native dependencies even if you're using the new CLI.
TLDR; So if you installed the plugin using the #4 you can import it like this: import { InAppBrowser } from '#ionic-native/in-app-browser';
If not, you may be using a newer version of Ionic Native so you need to import it like this: import { InAppBrowser } from '#ionic-native/in-app-browser/ngx'
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**
I created ionic 3 project template 'tabs' using ionic start ionTutorial tabs (tabs which were generated: home/about/contact)
Then I added my own tabs using
ionic g page (tabs: project/notifications/settings).
Then I deleted home about and contact folders from /src/pages
I updated files:
tabs.html (there were changed tabTitle and tabIcon only) and
tabs.ts
import { Component } from '#angular/core';
import { ProjectPage } from '../project/project';
import { NotificationsPage } from '../notifications/notifications';
import { SettingsPage } from '../settings/settings';
#Component({...})
export class TabsPage {
tab1Root = ProjectPage;
tab2Root = NotificationsPage;
tab3Root = SettingsPage;
constructor() { }
}
and app.module.ts
//this was updated (3x import)
import { ProjectPage } from '../pages/project/project';
import { NotificationsPage } from '../pages/notifications/notifications';
import { SettingsPage } from '../pages/settings/settings';
import { TabsPage } from '../pages/tabs/tabs';
#NgModule({
declarations: [
MyApp,
ProjectPage, //this was updated
NotificationsPage, //this was updated
SettingsPage, //this was updated
TabsPage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
ProjectPage, //this was updated
NotificationsPage, //this was updated
SettingsPage, //this was updated
TabsPage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
I received an error
Error: Module build failed: Error: ENOENT: no such file or directory, open
'\src\pages\about\about.ts'
After that I closed web browser and I tried to run ionic serve again and here are results
Starting app-scripts server: --address 0.0.0.0 --port 8100 --livereload-port 35729 --dev-logger-port 53703 --nobrowser
watch started ...
build dev started ...
and the command line 'is back'.
In my case the solution was to remove all files from www/build folder and restart dev server. The app is working fine now.
Hello everyone when i'm compile my app in prod release i got an error
Can't bind to 'ngModel' since it isn't a known property of 'ion-select'.
My code
<ion-select #sel1 [(ngModel)]="Selectedcat" (ngModelChange)="onChange()" >
i make this configuration in appmodule :
imports: [
BrowserModule,
HttpModule,
Ionic2RatingModule ,
FormsModule,
IonicModule.forRoot(MyApp),
IonicStorageModule.forRoot(),
IonicImageLoader.forRoot()
]
thanks for yours help
I solved my problem
the problem was because I use in a component so you need to add in components.modules.ts
imports: [IonicModule],
that's all
You need to add this to components modules
import { IonicModule } from '#ionic/angular';
import { FormsModule } from '#angular/forms';
#NgModule({
imports: [
IonicModule,
FormsModule
];
})
import { FormsModule } from '#angular/forms';
Simply, import the above (FormsModule) module in your modules page it will work!
I am working with ionic v3.2.0 and as a part of requirement I have created another root component named as start.component.ts and start.modulue.ts. Which is a just copy of app.component.ts and app.modulue.ts.
I have implemented lazy loading in appModule.
main.ts
import { AppModule } from "./app.module";
platformBrowserDynamic().bootstrapModule(AppModule);
app.component.ts
export class MyApp {
#ViewChild(Nav) nav: Nav;
rootPage: any = "LoginPage";
...
}
Everything is working fine and Login module is getting load.
No I changed to startModule
main.ts
import { StartModule } from "./start.module";
platformBrowserDynamic().bootstrapModule(StartModule);
start.component.ts
export class StartApp {
#ViewChild(Nav) nav: Nav;
rootPage: any = "LoginPage";
...
}
This is giving me error like :
main.js:1436 ERROR Error: Uncaught (in promise): invalid link: LoginPage
login.module.ts
import { NgModule } from '#angular/core';
import { IonicPageModule } from 'ionic-angular';
import { LoginPage } from './login';
#NgModule({
declarations: [
LoginPage
],
imports: [
IonicPageModule.forChild(LoginPage)
],
exports: [
LoginPage
]
})
export class LoginPageModule {}
login.ts
#IonicPage()
#Component({
selector: 'page-login',
templateUrl: 'login.html',
})
export class LoginPage {
....
}
P.S. : If I remove LazyLoding, everything is working fine. And I have tried using latest ionic version 3.4.0, but same error.
Solution rename your file from start.module.ts back to app.module.ts.
because when ionic start compilation it start looking for file named app.module.ts when it didn't find it in app directory; then generate warning and error similar to this
The main app NgModule was not found at the following path:
C:\Users\muham\Documents\ionic-projects\todo\src\app\app.module.ts
Which means it is hard coded in ionic-cli for compilation process. So, application require file named app.module.ts in app to compile and build.
Hopefully this will resolve the problem
