Intelligent autofocus for Angular that works everywhere — even on iOS!
- 🚀 Simple to use — just add the
ngxAutofocus
directive to any element - 📱 iOS Support — special iOS handler improves focus behavior (note: due to WebKit limitations, keyboard may require a tap to appear)
- 🎯 Smart focusing — supports conditional focus and dynamic content
- 🎭 Animation aware — automatically waits for animations to complete
- ⚡ Synchronous mode — optional immediate focus without delays
- 🧪 Fully tested — comprehensive test coverage for reliability
npm install @eurusik/ngx-autofocus --save
or
yarn add @eurusik/ngx-autofocus
This library is compatible with Angular 18.0.0 and above. It uses modern Angular features including the standalone components architecture and the new Input API introduced in Angular 18.
import { NgxAutofocusDirective } from '@eurusik/ngx-autofocus';
@Component({
// ...
standalone: true,
imports: [NgxAutofocusDirective],
})
export class YourComponent {}
<!-- Simple autofocus -->
<input ngxAutofocus>
<!-- Conditional autofocus -->
<input [ngxAutofocus]="shouldFocus">
NgxAutofocus comes with three specialized handlers to manage different focus scenarios:
The default handler provides smart focus with animation awareness:
- Automatically waits for Angular animations to complete
- Uses a race condition between animation detection and timeout
- Runs outside Angular zone for better performance
import { NGX_AUTOFOCUS_HANDLER, NgxDefaultAutofocusHandler } from '@eurusik/ngx-autofocus';
@Component({
// ...
providers: [
{
provide: NGX_AUTOFOCUS_HANDLER,
useClass: NgxDefaultAutofocusHandler
}
]
})
Specialized handler for iOS devices that solves common focus issues:
- Creates a temporary invisible input to trigger the keyboard
- Copies relevant attributes from the original input
- Uses precise timing to overcome iOS focus limitations
- Properly cleans up temporary elements
This handler is automatically used when an iOS device is detected.
Simplified handler for immediate focus without delays:
import { NGX_AUTOFOCUS_HANDLER, NgxSynchronousAutofocusHandler } from '@eurusik/ngx-autofocus';
@Component({
// ...
providers: [
{
provide: NGX_AUTOFOCUS_HANDLER,
useClass: NgxSynchronousAutofocusHandler
}
]
})
Configure focus behavior with custom options:
import { NGX_AUTOFOCUS_OPTIONS } from '@eurusik/ngx-autofocus';
@Component({
// ...
providers: [
{
provide: NGX_AUTOFOCUS_OPTIONS,
useValue: {
delay: 300, // Delay in ms before focusing
preventScroll: true, // Prevent automatic scrolling
query: 'input, button' // Custom query for finding focusable elements
}
}
]
})
You can create your own focus handler by extending the AbstractNgxAutofocusHandler
class:
import { ElementRef } from '@angular/core';
import { AbstractNgxAutofocusHandler, NgxAutofocusOptions } from '@eurusik/ngx-autofocus';
export class MyCustomHandler extends AbstractNgxAutofocusHandler {
constructor(
protected override readonly el: ElementRef<HTMLElement>,
protected override readonly options: NgxAutofocusOptions
) {
super(el, options);
}
public setFocus(): void {
// Your custom focus implementation
console.log('Custom focus logic');
this.element.focus({ preventScroll: this.options.preventScroll });
}
}

Note for iOS users: Due to a WebKit limitation, programmatic focus on iOS doesn't automatically trigger the keyboard. Elements will receive focus correctly, but you'll need to tap once to make the keyboard appear. Apple is working on fixing this in future iOS versions.
The project includes a demonstration application showcasing various NgxAutofocus scenarios:
git clone https://github.com/eurusik/ngx-autofocus.git
cd ngx-autofocus
npm install
npm start
Open your browser and navigate to http://localhost:4200/
.
The demo includes a special iOS simulation mode that demonstrates how the iOS handler works:
- Shows the temporary input element creation process
- Visualizes the focus sequence
- Allows testing iOS behavior on non-iOS devices
The directive has comprehensive test coverage to ensure reliability across different scenarios:
