When $refs is not defined, it means that it is still functional and operational

In the process of developing a native hybrid app with Nuxt JS 2.9.1 and Vuetify JS, I have integrated a notification component into my layout file default.vue. This component is essential for triggering notifications via a Cordova plugin on every page.

During the HTTP GET request to a server on each page (using Axios), it becomes necessary to access a specific object from an array based on its index. However, due to method constraints, direct access to individual object indexes is not possible. As a workaround, I've created a hidden <div> that contains references to each object correlated with the current URL. By utilizing the ref, these references are accessible within my methods.

Despite the functionality working correctly, errors like

Cannot read property '$refs' of undefined
and
Cannot read property 'innerText' of undefined
are encountered. Although minor in impact, resolving such issues remains a priority for enhanced performance.

<template>
  // Vue template code here
</template>

<script>
// Vue script code here
</script>

The above snippet illustrates my notification component embedded within each view. To address the error scenarios, suggest alternative optimization strategies or potential enhancements that can be implemented.

Answer №1

Consider replacing

document.addEventListener("deviceready", this.startFetchNotifications(), false)

with

document.addEventListener("deviceready", this.startFetchNotifications, false)

to ensure that the startFetchNotifications function is called only when the deviceready event listener is triggered, not when the event is created.

Answer №2

Avoid utilizing the $ref feature in Vue.js at all costs...

The $ref object remains empty until after the initial DOM rendering, making it ineffective in the mounted() lifecycle hook.

For more information, refer to: https://v2.vuejs.org/v2/api/?#ref
