I need to make adjustments to an Angular application so that it can run smoothly on older machines. Is there a more efficient method for updating a text input field without using (keyup) to update after each keystroke? I haven't been able to find any solutions that reduce the number of requests needed. Any ideas would be greatly appreciated. Thank you!
When working with ReactiveForms and rxjs :
myForm: FormGroup = new FormGroup({
name: new FormControl('')
});
ngOnInit() {
this.myForm.valueChanges.pipe(
debounceTime(1000), // wait for user to finish typing
switchMap(value => {
return this.http....
})
).subscribe();
}
In your HTML template :
<input [formControl]="name">
Don't forget to include ReactiveFormsModule in the imports array of your ngModule.
Utilize the powers of ReactiveFormsModule
const fieldControl = new FormControl();
fieldControl.valueChanges.pipe(
debounceTime(500)
).subscribe(content => {
// implement content value
});
<input [formControl]="fieldControl" />
