Installing the package

First of all, we need to install the Angular Material Design package. That is relatively simple using the Angular CLI:

ng new chap10
cd chap10
npm install --save @angular/material 
npm install --save @angular/animations
npm install --save hammerjs 

We install two packages here, @angular/material and the hammerjs packages. The first one includes in our app, the Material Design modules, which we will use in the next section. The second package, however, is a JavaScript implementation of touch movements. Some Material Design components such as slider depend on hammerjs.

Then, as per the NgModule specification, we can import MaterialModule as follows:

//src/app/app.module.ts

import { MaterialModule } from '@angular/material';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {...
