Question

Transferring information between two Vue components using a variable declared in the main JavaScript file

In my project, I am working with two separate Vue files - let's say 1.vue and 2.vue - along with a main JS file.

Within my main.js file, there is a variable xyz under the window.App data method.

I am looking to utilize this variable as a shared data variable that can be accessed by both of my Vue files. For example, 1.vue will assign some data to this variable, and 2.vue will be able to access this data.

javascript vue.js

Answer №1

There are a couple of effective methods for transferring data between components (for example, 1.vue and 2.vue).

One way is to utilize props and events. Define a variable like xyz in your root instance data. Then, in 1.vue, pass this value as a prop and update it as needed. By triggering an event when the value changes in 1.vue, you can ensure that the root instance updates, allowing 2.vue to access the updated value.
Another option is to use vuex. Vuex establishes a shared state accessible to all components via a store. Through mutations and actions, you can modify the value, and other components will dynamically respond to these changes using a computation.

As stated in the guidelines

When transferring data between components in Vue, it is recommended to use props in the child component and v-bind or : in the parent component.

Example of Parent Vue :

<child-component :data="example"></child-component>
<script>
export default {
  data: () => ({
    example: [1,2,3]
  })
</script>

Example of Child Vue:

<div v-for="item in example"></div>

<script>
export default {
  props: {
    example: Array // Array is the data type (can be Object, Array or String)
  }
</script>

Just a heads up: I found it a bit challenging to get everything functioning correctly.

Edit : Alternatively, a mixin class could be used to manage and update the variable
