Angular Material Icons is a popular icon set for use in Angular applications. In this blog, we will discuss how to add a logout icon using Angular Material Icons in an Angular application.
To get started, we need to add the Angular Material Icons package to our project. We can do this by running the following command in the terminal:
npm install @angular/material @angular/cdk @angular/animations @angular/material-icons
Once we have installed the package, we can add the logout icon to our application. Here's an example of how to do this:
- Import the required modules in the
app.module.tsfile:
import { MatIconModule } from '@angular/material/icon';
import { MatButtonModule } from '@angular/material/button';
import { MatMenuModule } from '@angular/material/menu';
- Add the imported modules to the
importsarray:
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
MatIconModule,
MatButtonModule,
MatMenuModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
- Use the
mat-icon-buttonelement to create a button with an icon:
<button mat-icon-button [matMenuTriggerFor]="menu">
<mat-icon>logout</mat-icon>
</button>
In this code, the mat-icon-button element creates a button with an icon using Angular Material Icons. The matMenuTriggerFor attribute specifies the dropdown menu to open when the button is clicked.
The mat-icon element inside the button specifies the icon to use. In this case, it is the "logout" icon.
- Use the
mat-menuelement to create a dropdown menu:
<mat-menu #menu="matMenu">
<button mat-menu-item (click)="logout()">Logout</button>
</mat-menu>
The mat-menu element creates the dropdown menu. The #menu attribute creates a reference to the menu that can be used later in the code.
The mat-menu-item element creates a button inside the dropdown menu with the text "Logout". The (click) event listener calls the logout() function in the component when the button is clicked.
- Define the
logout()function in the component:
logout() {
// Perform logout action here
}
6. Full sample code:
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 { MatIconModule } from '@angular/material/icon';
import { MatButtonModule } from '@angular/material/button';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
MatIconModule,
MatButtonModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
app.component.html:
<button mat-icon-button color="primary" (click)="logout()">
<mat-icon>logout</mat-icon>
</button>
app.component.ts:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
logout() {
// code to logout user
}
}
In this example, we import the MatIconModule and MatButtonModule modules from Angular Material in our app.module.ts file. We then use the mat-icon-button and mat-icon components in our app.component.html file to display the logout icon. Finally, we define the logout function in our app.component.ts file, which will contain the code to log the user out of our application.
Note that the actual code to log the user out will depend on the implementation of your authentication system. The logout function in this example is just a placeholder.
That's it! You have now added a logout icon using Angular Material Icons in your Angular application.
