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.ts
file:
import { MatIconModule } from '@angular/material/icon';
import { MatButtonModule } from '@angular/material/button';
import { MatMenuModule } from '@angular/material/menu';
- Add the imported modules to the
imports
array:
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
MatIconModule,
MatButtonModule,
MatMenuModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
- Use the
mat-icon-button
element 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-menu
element 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.
