The function upgradeDom() from vue mdl componentHandler is not returning a valid function

Attempting to integrate mdl into a vue.js project (using vue v2.1) and encountering a familiar issue to that discussed here. However, when I include

mounted () { componentHandler.upgradeDom()}
in my App.vue, I am receiving the following error:

TypeError: _materialMin2.default.upgradeDom is not a function

Interestingly, if I type componentHander.upgradeDom() in the browser console, it works as expected without any errors. But when I

console.log(componentHandler.upgradeDom())
in the mounted hook, it returns an empty object. I have also attempted to use this.$nextTick handler on mounted, but it did not resolve the issue.

The material.js file is imported like this:

import componentHandler from 'material-design-lite/material.min.js'
.

I even tried adding it globally by inserting it in a script tag in index.html or loading it via CDN, but nothing seems to work correctly.

To simplify, here is the relevant code snippet:

import componentHandler from 'material-design-lite/material.min.js'

export default {
  name: 'app',
  components: {
    ...
  },
  mounted () {
    this.$nextTick(() => {
      componentHandler.upgradeDom()
    })
  }
}

Additionally, using ready () {..} (old school vue) instead of mounted () {...} eliminates the error, but also fails to update each element correctly.

Answer №1

Discovered a solution for the issue by referencing a similar problem encountered in react. Implemented this webpack approach, replacing require with

import componentHandler from 'exports?componentHandler!material-design-lite/material'
, and utilized the mounted hook as previously done.

Although facing a challenge with code not properly updating all child component elements within nextTick, relocating it to another child component that had most of the buggy elements appeared to resolve the issue. The code was originally located in App.vue.
