Question

I am new to Angular 2 and Angular Material I tried creating one example to check Angular Material but its not working. I am getting empty html page. My code is as follows.

App Component ts:

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

App Module .ts

    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule } from '@angular/core';
    import { AppComponent } from './app.component';
    import {MdSidenavModule,MdMenuModule} from '@angular/material';
    import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; 
    import {NoopAnimationsModule} from '@angular/platform-browser/animations';
    import 'hammerjs';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MdSidenavModule,
    BrowserAnimationsModule,
    NoopAnimationsModule,
    MdMenuModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})


export class AppModule { }

I have included all dependencies as per mentioned on web. Please help me to resolve this.

Answer 1

Remove import { MaterialModule } from '@angular/material'; and MaterialModule from imports: [] too. It's deprecated since beta.3 [Changelog].

Also, add NoopAnimationsModule

import {NoopAnimationsModule} from '@angular/platform-browser/animations';

@NgModule({
  ...
  imports: [NoopAnimationsModule],
  ...
})

I also found your error issue listed in Github. Seems like fallback to animations version 4.1.3 is the solution for now.

Try npm install '@angular/animations"@4.1.3' --save

Let me know if that helps!

UPDATE:

md-menu isn't showing up because it needs a mdMenuTriggerFor which can open the menu. Until then, it stays hidden. Also, for sidenav to work, everything needs to be within the md-sidenav-container tag. Sidenav doc, Menu doc.

Please change your html code with following:

<md-sidenav-container style="height: 500px">

  <button md-icon-button [mdMenuTriggerFor]="menu">
    <md-icon>more_vert</md-icon>Menu
  </button>


  <md-sidenav opened="true" #sidenav 
      style="background-color: skyblue">
    <button md-raised-button style="margin: 2px 0 0 6px">
     Add
    </button>
    <p>This is Sidenav</p>
   </md-sidenav>

   <md-menu #menu="mdMenu">
     <button md-menu-item (click)="sidenav.open()"> Sidenav </button>
    <button md-menu-item> Settings </button>
    <button md-menu-item> Help </button>
  </md-menu>

</md-sidenav-container>
