What is the solution for fixing the "type object does not contain property" error in Angular?

Within my application, there is a parent component that houses a list of objects representing various fruits. When a user clicks on a fruit, its data is passed to the child component for display as detailed information.

        <app-details 
            [fruit]="selectedFruit"
        ></app-details>

Within the details template:

<div class="fruit-details">
    <h1>{{fruit.name}}</h1>
    <h1>{{fruit.color}}</h1>
    <h1>{{fruit.description}}</h1>
</div>

The 'fruit' property is defined as an object type in the details component. @Input()fruit: Object;

An error message appears indicating something like

Property 'description' does not exist on type 'Object'
. The issue can be resolved by specifying the "fruit" property with the datatype "Object". What is the best way to address this problem without removing the datatype?

Answer №1

To ensure consistency, establish an interface named Fruit and apply it as a type annotation:

interface Fruit { 
    name: string;
    color: string;
    description: string;
}

@Input() selectedFruit: Fruit;

Answer №2

Why not try utilizing @Input()fruit: string to convert your selectedFruit to a string format?

JSON.stringify(selectedFruit)

Then, in the details component, you can parse it like this:

let parsedFruit = JSON.parse(this.fruit);
console.log(parsedFruit);

Answer №3

After thorough research and to the best of my understanding, a simple solution to the issue is by declaring any variables you plan to use in your HTML at the class level of your component within the TypeScript file.

I trust this solution will successfully resolve the problem for anyone encountering it. Best regards, Beni Dayan.
