Getting an error from console when using mdIcon

Angular is throwing an error when I'm using mdIcon. Below is the code:

import {Component} from '@angular/core';
import {MdIcon} from '@angular2-material/icon';
@Component({
    selector: 'my-app',
    template: `
    <md-toolbar>
      <md-icon class="demo-toolbar-icon">menu</md-icon>
      <span>Default Toolbar</span>

      <span class="demo-fill-remaining"></span>

      <md-icon>code</md-icon>
    </md-toolbar>`,
    directives: [MdIcon,MdToolbar],

})
export class AppComponent {}

Error:

ORIGINAL EXCEPTION: No provider for MdIconRegistry! Error: DI Exception at NoProviderError.BaseException [as constructor] (exceptions.ts:14) at NoProviderError.AbstractProviderError [as constructor] (reflective_exceptions.ts:53) at new NoProviderError (reflective_exceptions.ts:85) at ReflectiveInjector_._throwOrNull (reflective_injector.ts:844) at ReflectiveInjector_._getByKeyDefault (reflective_injector.ts:873) at ReflectiveInjector_._getByKey (reflective_injector.ts:835) at ReflectiveInjector_.get (reflective_injector.ts:632) at ElementInjector.get (element_injector.ts:19) at DebugAppView._View_AppComponent0.createInternal (AppComponent.template.js:141) at DebugAppView.AppView.create (view.ts:110)

Can anyone please help me what i'm doing wrong here?

You should be able to just import the MaterialRootModule in your app.module.ts:

import { MaterialModule } from '@angular/material';
@NgModule({
  imports: [
    MaterialModule.forRoot(),
  ],
})

Update for the 2.0.0 release using material alpha 8-4:

You need to include MdIconRegistry as a provider in your app.modules.ts file. Here is a functional example:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { MdButtonModule } from '@angular2-material/button';
import { MdButtonToggleModule } from '@angular2-material/button-toggle';
import { MdCardModule } from '@angular2-material/card';
import { MdCheckboxModule } from '@angular2-material/checkbox';
import { MdGridListModule } from '@angular2-material/grid-list';
import { MdIconModule, MdIconRegistry } from '@angular2-material/icon';
import { MdInputModule } from '@angular2-material/input';
import { MdListModule } from '@angular2-material/list';
import { MdMenuModule } from '@angular2-material/menu';
import { MdProgressBarModule } from '@angular2-material/progress-bar';
import { MdProgressCircleModule } from '@angular2-material/progress-circle';
import { MdRadioModule } from '@angular2-material/radio';
import { MdSidenavModule } from '@angular2-material/sidenav';
import { MdSliderModule } from '@angular2-material/slider';
import { MdSlideToggleModule } from '@angular2-material/slide-toggle';
import { MdTabsModule } from '@angular2-material/tabs';
import { MdToolbarModule } from '@angular2-material/toolbar';
import { MdTooltipModule } from '@angular2-material/tooltip';

import { AppComponent } from './app.component';


@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,

        MdButtonModule,
        MdButtonToggleModule,
        MdCardModule,
        MdCheckboxModule,
        MdGridListModule,
        MdIconModule,
        MdInputModule,
        MdListModule,
        MdMenuModule,
        MdProgressBarModule,
        MdProgressCircleModule,
        MdRadioModule,
        MdSidenavModule,
        MdSliderModule,
        MdSlideToggleModule,
        MdTabsModule,
        MdToolbarModule,
        MdTooltipModule
    ],
    providers: [
        MdIconRegistry
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

Don't forget to install hammerjs + typings and add import 'hammerjs'; to your main.ts file if you want to use the md-slide-toggle, and md-slider modules.

For using standard icons you just need to put the font into your html (the simplest solution just to use CDN for the font): <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

The other ways are described in docs: http://google.github.io/material-design-icons/#icon-font-for-the-web

Also you need (as with any other material package) to place material module to NgModule configuration into imports.

You need to list it in providers or viewProviders and register some icons or iconsets

import {Component, ViewEncapsulation} from '@angular/core';
import {MdIcon} from '@angular2-material/icon';

@Component({
    selector: 'my-app',
    template: `
    <md-toolbar>
      <md-icon class="demo-toolbar-icon">menu</md-icon>
      <span>Default Toolbar</span>

      <span class="demo-fill-remaining"></span>

      <md-icon>code</md-icon>
    </md-toolbar>`,
    directives: [MdIcon,MdToolbar],
    viewProviders: [MdIconRegistry],
})
export class AppComponent {
    constructor(mdIconRegistry: MdIconRegistry) {
        mdIconRegistry
            .addSvgIcon('thumb-up', '/demo-app/icon/assets/thumbup-icon.svg')
            .addSvgIconSetInNamespace('core', '/demo-app/icon/assets/core-icon-set.svg')
            .registerFontClassAlias('fontawesome', 'fa');
    }
}
