How to Access `navigator`, `window`, and `document` in a Nuxt Application?

Dealing with Undefined Navigator, Window, and Document in Nuxt Application

When attempting to retrieve information such as UserAgent and Retina status within a Nuxt application, you may encounter errors related to undefined navigator, window, or document objects. This is due to the nature of Nuxt as a server-side rendering framework.

Solution:

To resolve this issue and access these objects in Nuxt, you can utilize one or more of the following approaches:

JavaScript Wrappers:

Wrap your code using the following structure:

<script>
import { jsPlumb } from 'jsplumb' // client-side library only, no SSR support

export default {
  mounted() {
    if (process.client) {
      // your JS code here like >> jsPlumb.ready(function () {})
    }
  },
}
</script>

Client-Only Components:

If certain components should only be rendered on the client side, consider wrapping them in tags:

<template>
  <div>
    <p>this will be rendered on both: server + client</p>

    <client-only>
      <p>this one will only be rendered on client</p>
    </client-only>
  <div>
</template>

Dynamic Imports for Unsupported Packages:

For packages that do not support server-side rendering, use dynamic imports within your component's definition:

export default {
  components: {
    [process.client &&& 'VueEditor']: () => import('vue2-editor'),
  }
}

By implementing these solutions, you can effectively access navigator, window, and document objects in your Nuxt application, ensuring that these features are available for use on the client side.
