In this chapter, we will showcase the configuration required to use a mat-input control in Angular Material.

Create Angular Application

Follow the following steps to update the Angular application we created in Angular 6 - Project Setup chapter −

Following is the content of the modified module descriptor app.module.ts.

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

Following is the content of the modified CSS file app.component.css.

.tp-form {
   min-width: 150px;
   max-width: 500px;
   width: 100%;
}
.tp-full-width {
   width: 100%;
}

Following is the content of the modified ts file app.component.ts.

import { Component } from '@angular/core';
import { FormControl } from "@angular/forms";
import {Validators} from '@angular/forms';
@Component({
   selector: 'app-root',
   templateUrl: './app.component.html',
   styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'materialApp';
   emailFormControl = new FormControl('', [
      Validators.required,
      Validators.email,
  ]);
}

Following is the content of the modified HTML host file app.component.html.

<form class = "tp-form">
   <mat-form-field class = "tp-full-width">
      <input matInput placeholder = "Favorite Food" value = "Pasta">
   </mat-form-field>
   <mat-form-field class = "tp-full-width">
      <textarea matInput placeholder = "Enter your comment"></textarea>
   </mat-form-field>
   <mat-form-field class = "tp-full-width">
      <input matInput placeholder = "Email" [formControl] = "emailFormControl">
      <mat-error *ngIf = "emailFormControl.hasError('email') 
         && !emailFormControl.hasError('required')">
         Please enter a valid email address
      </mat-error>
      <mat-error *ngIf = "emailFormControl.hasError('required')">
         Email is <strong>required</strong>
      </mat-error>
   </mat-form-field>
</form>
