Angular 6 Materials

Angular 6 Materials

For your idea, materials deliver a number of built-in modules. In Angular 6, features such as autocomplete, datepicker, slider, menu, grids and toolbar are available for use with materials.

We need to import the package for use with materials. Angular 2 also has all the features mentioned above so they are only as part of the @angular / core package. Angular 6 has created a separate @angular / materials module .. That helps the user to import the materials required.

You need to install two packages-materials and cdk-to start using materials. For advanced functionality, material components rely on the animation module so you need the animation package for the same, i.e. @angular / animations. The package was revised in the preceding chapter.

npm install --save @angular/material @angular/cdk

Let us now see the package.json. @angular/material and @angular/cdk are installed.

      "typescript": "~2.7.2"
   }
}

We have highlighted the packages that are installed to work with materials.

We will now import the modules in the parent module − app.module.ts as shown below.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatButtonModule, MatMenuModule, MatSidenavModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatButtonModule,
      MatMenuModule,
      FormsModule,
      MatSidenavModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

In the above file, we have imported the following modules from @angular/materials.

import { MatButtonModule, MatMenuModule, MatSidenavModule } from '@angular/material';

And the same is used in the imports array as shown below −

imports: [
   BrowserModule,
   BrowserAnimationsModule,
   MatButtonModule,
   MatMenuModule,
   FormsModule,
   MatSidenavModule
]

The app.component.ts is as shown below −

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   myData: Array;
   constructor() {}
}

Let us now add the material-css support in styles.css.

@import "~@angular/material/prebuilt-themes/indigo-pink.css";

Let us now add the material in app.component.html.

<button mat-button [matMenuTriggerFor] = "menu">Menu</button>
<mat-menu #menu = "matMenu">
   <button mat-menu-item>
      File
   </button>
   <button mat-menu-item>
      Save As
   </button>
</mat-menu>
<mat-sidenav-container class = "example-container">
   <mat-sidenav #sidenav class = "example-sidenav">
      Angular 6
   </mat-sidenav>
   <div class = "example-sidenav-content">
      <button type = "button" mat-button  (click) = "sidenav.open()">
         Open sidenav
      </button>
   </div>
</mat-sidenav-container>

Menu

Uses < mat-menu></mat-menu > to add a section. The file and Save As items are attached under the mat-menu to the button. A main button has been added to Menu. By using [matMenuTriggerFor]="menu "and using the menu with # in < mat-menu > the relation to the same is provided to the < mat-menu >.

SideNav

To add sidenav, we need the container <mat-sidenav></mat-sidenav-container>. < mat-sidenav></mat-sidenav > is attached to the container as a boy. Another div has been added which activates the sidenav using (click)="sidenav.open) Here is the menu and sidenav view in the browser –

Let us now use the materials to add a datepicker. To add a datepicker, the modules used to show the datepicker need to be import.

We have imported the following module in app.module.ts, as seen for the datepicker below.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatDatepickerModule, MatInputModule, MatNativeDateModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      FormsModule,
      MatDatepickerModule,
      MatInputModule,
      MatNativeDateModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

Modules like MatDatepickerModule, MatInputModule, and MatNativeDateModule were imported here.

Now, the app.component.ts is as shown below −

import { Component } from '@angular/core';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   myData: Array<any>;
   constructor() {}
}

The app.component.html is as shown below −

<mat-form-field>
   <input matInput [matDatepicker] = "picker" placeholder = "Choose a date">
   <mat-datepicker-toggle matSuffix [for] = "picker"></mat-datepicker-toggle>
   <mat-datepicker #picker></mat-datepicker>
</mat-form-field>
