Handling uninitialized reactive objects in Typescript Vue components

Within a Vue 3 component using the composition API, I am utilizing reactive objects that will be filled asynchronously with data from an external source.
To achieve this, I am utilizing a "nullable" {} object:

import { Ref, ref } from 'vue'
    import { Car } from '@mytypes/vehicles'

    const car: Ref<Car|{}> = ref({})

    fetch('/cars/42').then((result: Car) => {
    car.value = result
    }
    

This allows me to display potentially empty data in the template

<h1>{{ car.model }}</h1>
    <label>Brand</label> {{ car.brand }}
    <label>Engine</label> {{ car.engine }}
    <label>Color</label> {{ car.color }}
    

However, I find this method to be somewhat of a workaround, as each instance requires me to repeatedly declare Car|{} to satisfy Typescript.

I believe there must be a more proper way to handle this scenario, don't you agree?

Answer №1

In my opinion, I would make the reference able to be null:

let vehicle: Reference<Vehicle | null> = reference(null);

After that, I would implement the optional chaining method in the template:

<h2>{{ vehicle?.type }}</h2>
