Is there a way to minimize the use of .value in Vue 3?

After recently diving into Vue 3, I find myself struggling to grasp some key concepts of the composition API. My current challenge involves converting a library from Vue 2 to Vue 3, where a reactive property named layout is being passed down to child components.

In the parent component, I am passing down layout to children like so:

setup(props){
    const layout = ref({'width': 10, ... })
    return {
        layout,
        ...
    }
}

The issue arises when attempting to access width or any other reactive value within layout from child components. This requires using the syntax layout.value.width. The problem lies in the fact that throughout the project, references to layout are made using just layout.width. Therefore, adding a .value to every instance where layout is accessed becomes cumbersome. Is there a way to avoid this repetition, or am I missing crucial aspects of the composition API?

Answer №1

There are multiple ways to achieve this:

  1. Absolutely! It is possible to work without using the .value. In order to do this, you will need to utilize the vue experimental version

or

  1. Another option is to create a reactive variable, like so:
<script setup>
import { reactive } from 'vue'

const layout = reactive({'width': 10, ... })
</script>

Answer №2

Utilizing the reactivity transform function will automatically add .value to your reactive variables by utilizing $ref(). This innovative tool was recently introduced, but is now being phased out of Vue's core functionalities. Instead, opt for the reliable Vue Macros plugin to eliminate the need for .value syntax.
