What are some alternative methods for transferring data between Vue sibling components without relying on 'params'?

I currently have 2 main components in my application:

  • Proyectos.vue
  • Reuniones.vue

In the Proyectos component, I make a `GET` request which retrieves an array of project objects. This list of projects is then displayed in a table.

Structure of Project Object:

    {
        objetivo:"", 
        fecha: "",
        reuniones: [
        {
            titulo: "",
            fecha: ""
        },
        {
            titulo: "",
            fecha: ""
       }]
   }

For each row in the table, I have a JavaScript object representing a project. When a user clicks on a button, I want to send this project object to the Reuniones component. In the Reuniones component, I will perform certain actions such as iterating over the data.

Avoiding ID in URL

I am exploring ways to avoid sending the project ID through the URL and making a new GET request for the object. Instead, I want to utilize the object already available in the Proyectos component.

Using Custom Events

I attempted to use custom events by using `$emit` and `$on`, but encountered issues because the Reunions component was not loaded yet, preventing it from listening to events emitted from the Proyectos component.

Code snippet from Proyectos.vue:

projectSelected (project) {
     // Emitting an event with the project object
     this.$root.$emit ('send', project)
     // Navigating to the 'reuniones' route to load the Reuniones.vue component
     this.$router.push('reuniones')
}

Code snippet from Reuniones.vue:

this.$root.$on('send', (data) => {
     console.log (data)
})

The desired behavior is to effectively pass an object between different components within the application.

Answer №1

When tackling this issue, I recommend exploring the concept of a global eventBus in your application. You can find more information about it here

This approach enables you to easily define methods for handling your GET requests and monitor any changes within your .vue components using computed properties or watchers.
