Angular is throwing an error because it cannot assign a type of 'string' to a type of '(value: any) => void'

When attempting to pass a value to an @Input() in Angular, I am encountering some issues. Unfortunately, I am struggling to identify what mistake I might be making.

<my-component
  [foo]="bar"
></my-component>
  private _foo = ''
  @Input() foo(value: any) {
    this._foo = value?.toString() || ''
  }

Can anyone spot the error here?

The error message reads:

Type 'string' is not assignable to type '(value: any) => void'.

Answer №1

If you are looking to set a value for your input, consider using a setter method:

  private _bar = ''
  @Input() set bar(value: any) {
    this._bar = value?.toString() || ''
  }
