I am trying to plot wind barb using my angular application. I used angular-highchart package but it's showing me below error -
Error: Highcharts error #17: www.highcharts.com/errors/17
import { Component } from '#angular/core';
import { Chart } from 'angular-highcharts';
import { MapChart } from 'angular-highcharts';
#Component({
selector: 'app-root',
template: `
<div [chart]="chart"></div>
`
})
export class AppComponent {
chart = new Chart({
title : { text : 'simple chart' },
xAxis: {
type: 'datetime',
offset: 40
},
series: [{
type: 'windbarb',
name:"Wind Direction",
data: [
[9.8, 177.9],
[10.1, 177.2]
]
}, {
type: 'area',
name:'WindSpeed',
data: [
[9.8, 177.9],
[10.1, 177.2]
],
}]
});
constructor() {
}
}
here
Check module.ts imports as per angular-highcharts docs
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { ChartModule, HIGHCHARTS_MODULES } from 'angular-highcharts';
import exporting from 'highcharts/modules/exporting.src';
import windbarb from 'highcharts/modules/windbarb.src';
export function highchartsModules() {
// apply Highcharts Modules to this array
return [ exporting,windbarb ];
}
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';
#NgModule({
imports: [ BrowserModule, FormsModule,ChartModule ],
declarations: [ AppComponent, HelloComponent ],
providers: [
{ provide: HIGHCHARTS_MODULES, useFactory: highchartsModules } // add as factory to your providers

})
export class AppModule { }

I have the following code based on the angular material documentation:
In my HTML
<button mat-raised-button (click)="openBottomSheet()">Abrir BottomSheet</button>
and, in my page ts archive :
import { Component, OnInit } from '#angular/core';
import {MatBottomSheet, MatBottomSheetRef} from '#angular/material/bottom-sheet';
#Component({
selector: 'app-login',
templateUrl: './login.page.html',
styleUrls: ['./login.page.scss'],
})
export class LoginPage implements OnInit {
constructor(private bottomSheet: MatBottomSheet) {}
openBottomSheet ()
{
this.bottomSheet.open(BottomSheetOverviewExampleSheet)
}
ngOnInit() {
}
}
#Component({
selector: 'bottom-sheet-overview-example-sheet',
templateUrl: 'bottom-sheet-overview-example-sheet.html',
})
export class BottomSheetOverviewExampleSheet {
constructor(private bottomSheetRef: MatBottomSheetRef<BottomSheetOverviewExampleSheet>) {}
openLink(event: MouseEvent): void {
this.bottomSheetRef.dismiss();
event.preventDefault();
}
}
The problem is that when trying to show the bottomsheet I get the following error:
ERROR TypeError: this.bottomSheet.open is not a function
at LoginPage.openBottomSheet
In my page component i have :
import { LoginPageRoutingModule } from './login-routing.module';
import { LoginPage } from './login.page';
import { MaterialModule } from '../material.module';
import {MatBottomSheetModule} from '#angular/material/bottom-sheet'
#NgModule({
imports: [
CommonModule,
FormsModule,
IonicModule,
LoginPageRoutingModule,
MaterialModule,
MatBottomSheetModule
],
declarations: [LoginPage]
})
export class LoginPageModule {}
The material Module
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import {
MatTableModule,
MatStepperModule,
MatButtonModule,
MatFormFieldModule,
MatInputModule,
MatOptionModule,
MatSelectModule,
MatIconModule,
MatPaginatorModule,
MatSortModule
} from "#angular/material";
import { MatCheckboxModule } from '#angular/material/checkbox';
import {MatBottomSheetRef, MatBottomSheet} from '#angular/material/bottom-sheet';
#NgModule({
declarations: [],
providers: [
{ provide: MatBottomSheetRef, useValue: {} },
{ provide: MatBottomSheet, useValue: {} },
],
imports: [
CommonModule,
],
exports: [
MatTableModule,
MatStepperModule,
MatButtonModule,
MatFormFieldModule,
MatInputModule,
MatIconModule,
MatOptionModule,
MatSelectModule,
MatPaginatorModule,
MatSortModule,
MatCheckboxModule
]
})
export class MaterialModule { }
You must import the material design module that holds this function.
Make sure you have import {MatBottomSheetModule} from '#angular/material/bottom-sheet';
imported in your component module or app module.
Update:
Instead of
import {
MatTableModule,
MatStepperModule,
MatButtonModule,
MatFormFieldModule,
MatInputModule,
MatOptionModule,
MatSelectModule,
MatIconModule,
MatPaginatorModule,
MatSortModule
} from "#angular/material";
try this,
import {MatBottomSheetRef, MatBottomSheet, MatBottomSheetModule} from '#angular/material/bottom-sheet';
import {MatCheckboxModule} from "#angular/material/checkbox";
import {MatFormFieldModule} from "#angular/material/form-field";
import {MatOptionModule} from "#angular/material/core";
import {MatSortModule} from "#angular/material/sort";
import {MatTableModule} from "#angular/material/table";
import {MatSelectModule} from "#angular/material/select";
import {MatIconModule} from "#angular/material/icon";
import {MatPaginatorModule} from "#angular/material/paginator";
import {MatStepperModule} from "#angular/material/stepper";
import {MatInputModule} from "#angular/material/input";
import {MatButtonModule} from "#angular/material/button";
in MaterialModule
Make sure you have following things.
1). in your login-page.module.ts file, "BottomSheetOverviewExampleSheet" in declarations and entryComponents
like this,
import { LoginPageRoutingModule } from './login-routing.module';
import { LoginPage, BottomSheetOverviewExampleSheet } from './login.page';
import { MaterialModule } from '../material.module';
import { MatBottomSheetModule } from '#angular/material/bottom-sheet';
#NgModule({
imports: [
CommonModule,
FormsModule,
IonicModule,
LoginPageRoutingModule,
MaterialModule,
MatBottomSheetModule
],
declarations: [LoginPage, BottomSheetOverviewExampleSheet],
entryComponents: [BottomSheetOverviewExampleSheet],
})
export class LoginPageModule {}
2). hope you have bottom-sheet-overview-example-sheet.html
like this,
<mat-nav-list>
<a mat-list-item (click)="openLink($event)">
<span mat-line>
<!--Your message To Show -->
Test Message
</span>
</a>
</mat-nav-list>
I am fetching data from service on APP_INITIALIZER, but getting error as
Property 'initializeData' does not exist on type of AppConfig
don't know what is the exact issue here. any one help me?
here is my module file:

import { AppComponent } from './app.component';
import { RoutesModule } from './routes/routes.module';
import { SignInComponent } from './shared-components/user/sign-in/sign-in.component';
export function initializeApp() {
return () => AppConfig.initializeData(); //getting error here
}
#NgModule({

Here is my service.ts:
import { Injectable, OnInit } from '#angular/core';
import { ShareOption } from "./../user/sign-in/sign-in.component";
import { Store, select } from '#ngrx/store';

#Injectable({
providedIn: 'root'
})
export class AppConfig {
constructor(){}
initializeData() {
return new Promise((resolve, reject) => resolve(true));
}
}
I bought the service in parameter, got issue fixed. my updated chunk is:
export function initializeApp(service:AppConfig) { //getting service object in param
return () => service.initializeData();
}
I have an Angular app that contains a load button. When you click the load button it renders a remote UMD library.
The first time I click the load button I have the following error while importing my library using SystemJS:
core.js:15714 ERROR Error: Uncaught (in promise): TypeError: Cannot read property '__source' of undefined
TypeError: Cannot read property '__source' of undefined
at StaticInjector.push../node_modules/#angular/core/fesm5/core.js.StaticInjector.get (core.js:8984)
when I click a second time, no errors and the library renders correctly.
I narrowed the issue to this statement in my code:
export class PostService {
constructor(private httpClient: HttpClient) { }
If I remove the httpClient service, the library loads correctly but I don't have access to the HttpClient.
If anyone has an idea why my code behaves that way it would be greatly appreciated!
Here is my setup below:
I have the following components im my remote library:
sample-pack-lib.component
|_db2-chart2.component
|_post.service
The library 'samplePack-lib' is compiled with 'ng build samplePack-lib' and I exposed the following output through an express server:
dist/sample-pack-lib/sample-pack-lib.umd.js

The problem was with the HttpCLientModule.
Previously I imported it that way:
import { HttpClientModule } from '#angular/common/http';
It should be:
import * as HttpClientModule from '#angular/common/http';
Hello i want to insert a select dropdownlist with angular material.
My question is where we put this exactly :
export interface Food {
value: string;
viewValue: string;
}
export class SelectOverviewExample {
foods: Food[] = [
{value: 'steak-0', viewValue: 'Steak'},
{value: 'pizza-1', viewValue: 'Pizza'},
{value: 'tacos-2', viewValue: 'Tacos'}
];
}
Link of the component
I did this :
app.module .ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule } from '#angular/core';
import {MatTabsModule} from '#angular/material/tabs';
import {MatSelectModule} from '#angular/material/select';
import {MatInputModule} from '#angular/material/input';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '#angular/platform-browser/animations';
import { InterfaceComponent } from './interface/interface.component';
#NgModule({
declarations: [
AppComponent,
InterfaceComponent
],
imports: [
BrowserModule,
MatTabsModule,
BrowserAnimationsModule,
MatSelectModule,
MatInputModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
And i added html code in app.component.html
Result :
select list but without options cause i didn't know where i will put the export details
enter image description here
for this case you have to put in the app.component.ts like:
import { Component } from '#angular/core';
interface Food {
value: string;
viewValue: string;
}
#Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent {
foods: Food[] = [
{value: 'steak-0', viewValue: 'Steak'},
{value: 'pizza-1', viewValue: 'Pizza'},
{value: 'tacos-2', viewValue: 'Tacos'}
];
}
I, am using the Angular template in visual studio 2017. Then I updated to angular 5.2. I, tried to find the solution. But didn't got exact solution.
The service class is calling the http call.However I, am getting an error as
Service.TS
import { Injectable } from '#angular/core';
import { LoginViewModel as loginVM } from "../../viewmodel/app.viewmodel"
import { HttpClient, HttpHeaders } from "#angular/common/http";
#Injectable()
export class LoginService {
private loginUrl = "Account/Authentication";
private _httpClientModule: HttpClient;
constructor(httpClientModule: HttpClient) {
this._httpClientModule = httpClientModule;
}
public LoginHttpCall(_loginVM: loginVM) {
const headers = new HttpHeaders().set('Content-Type', 'application/json; charset=utf-8');
this._httpClientModule.post(this.loginUrl, _loginVM, { headers }).
subscribe(data => {
console.log(data);
},
err => {
console.log("Error occured.");
});
}
}
Here is my Component class
import { Component } from '#angular/core';
import { AppComponent } from "../app/app.component";
import { LoginService } from "../../service/account/app.service.account.login";
import { LoginViewModel } from "../../viewmodel/app.viewmodel";
declare var componentHandler: any;
#Component({
selector: 'login',
templateUrl: './login.component.html',
styleUrls: ['./login.component.css'],
providers: [LoginViewModel, LoginService]
})
export class LoginComponent {
private _appComponent: AppComponent;
private _loginService: LoginService;
constructor(private appComponent: AppComponent, loginService: LoginService) {
this._appComponent = appComponent;
this._appComponent.menulist = false;
this._loginService = loginService;
}
}
app.shared.module.ts
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { RouterModule } from '#angular/router';
import { AppComponent } from './components/app/app.component';
import { HomeComponent } from './components/home/home.component';
import { LoginComponent } from './components/login/login.component';
import { MobileComponent } from './components/mobile/mobile.component';
#NgModule({

HomeComponent,
LoginComponent,

imports: [

{ path: 'home', component: HomeComponent },
{ path: 'login', component: LoginComponent },
{ path: 'mobile', component: MobileComponent },
{ path: '**', redirectTo: 'home' }
])
]
})
export class AppModuleShared {
}
I, don't know where I, am doing mistake. Since I , am new in angular. I tried to add HttpClient under #NgModule but gives some other error . Since As per my knowledge I don't need to add in app.shared.module.ts file. Since HttpClient is used in service and component level.
Can anyone please tell me where I, am doing wrong .
HttpClient needs for the module HttpClientModule instead of HttpModule to be imported and added in the imports of the module.
For more see Documentation
import { HttpClientModule } from '#angular/common/http';
#NgModule({
declarations: [
...
],
imports: [
...
HttpClientModule,
...
]
})
export class AppModuleShared { }
npm clear cache
npm update
rm -rf /node_modules
npm i --save
Then import same module into app root module.
Hope it works for you.
