The error code TS2345 indicates that the argument type 'Event' cannot be assigned to a parameter type 'string'

Hello, I'm a newcomer to utilizing Angular and I'm struggling to identify where my mistake lies. Below is the TypeScript code in question:

import { Component } from '@angular/core';

    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent {
      loadedFeature = 'recipe';
    
      onNavigate(feature: string) {
        this.loadedFeature = feature;
      }
    }

Here is the corresponding HTML:

<app-header (featureSelected)="onNavigate($event)"></app-header>
<div class="container">
  <div class="row">
    <div class="col-md-12">
      <app-recipies *ngIf="loadedFeature === 'recipe'"></app-recipies>
      <app-shopping-list *ngIf="loadedFeature !== 'recipe'"></app-shopping-list>
    </div>
  </div>
</div>

Furthermore, here is the error message encountered:

Error: src/app/app.component.html:1:43 - error TS2345: Argument of type 'Event' is not assignable to parameter of type 'string'.

1 <app-header (featureSelected)="onNavigate($event)"></app-header>
                                            ~~~~~~

  src/app/app.component.ts:5:16
    5   templateUrl: './app.component.html',
                     ~~~~~~~~~~~~~~~~~~~~~~
    Error occurs in the template of component AppComponent.

Answer №1

onNavigate(featureName: string) {
    this.selectedFeature = featureName;
}

You have specified the type of featureName as a string, but it seems to be incorrect. Please refer to the documentation for app-header and update the correct data type.

In the meantime, changing it to any may temporarily solve the issue, but it is recommended to use the proper typing.

Answer №2

handleSelection(feature: string){
        this.selectedFeature.emit(feature);
    }

Make sure to review the code snippet provided in header.component.html Possibly useful
