What is the best approach to reutilize a Vue SFC component instance across multiple components?

Reasons for Seeking a Solution:

I have created a single file component, called Player, which is responsible for displaying videos and images. Due to its high memory consumption, I want to instantiate it only once and use it across multiple pages (components under the root). Additionally, the Player component needs to be dynamically resizable using props, as it will be displayed differently on various pages. Moreover, since many pages utilize the Player component, I am exploring the possibility of utilizing Vue's Provide / Inject feature to make Player accessible everywhere.

Current Implementation:

// Player
<template>
    <div>
        ... // display images and video
    </div>
</template>

<script>
export default Vue.extend({
    props: {
        width: {
            type: Number,
            default: 284,
        },
        height: {
            type: Number,
            default: 214,
        },
    },
    data() {
        ... // images and video
    },
    methods: {
        ... // logic related to images and video
    },
})
// An example of `pages`
<template>
    <div>
        <player
            :width="592"
            :height="333"
        />
    ... // some other logic
    </div>
</template>

... // everything else

Desired Outcome:

To summarize, my vision for the Player component entails these key features:

  1. Initialization in the root component.
  2. The root component should Provide the Player component to all nested components.
  3. Pages within the root hierarchy should be able to pass props to the injected Player component in order to resize it as needed.

This represents my ideal scenario, but I am open to exploring alternative solutions as well.

Methods Attempted So Far:

  • I attempted to initialize the Player in memory, but I encountered challenges with rendering it.
  • I tried to treat the Player as a dynamic component, yet I struggled with determining where to slot it and how to initialize the Player.
  • I explored the concept of render functions for potential re-rendering strategies, but I found it difficult to apply in my specific case.
  • This post appeared promising, although I still lack clarity on implementing the proposed solution due to limited information provided.

There are a couple of methods to achieve this-

  1. To start, you can globally import the component in the main.js file and use it on any page without any restrictions. For example:
    import Vue from "vue";  
    import Player from "@/components/Player.vue";  
    Vue.component("AppButton", AppButton); 
  1. Alternatively, you can create a mixin named playerMixin.js within the mixins folder.
    Inside this mixin, import the Player component and then include the mixin in all pages where required.
    The code for the mixin should resemble the following:

playerMixin.js

import Player from "@/components/Player.vue";

export const playerMixin = {
  data() {
    // Include any relevant data properties related to player functionalities 
  },

  components: {
    Player,
  },

  methods: {
    // Define any methods associated with player functionalities
  }
}

Now, you have the flexibility to utilize this mixin in any page as demonstrated below:

AnyPage.vue

import { playerMixin} from "@/mixins/playerMixin.js";

export default {
  name: "AnyPage",
  mixins: [playerMixin],
}

The primary advantage of utilizing a mixin is that component imports only need to be done once and common Player functionality such as passing props and methods like play/pause can be defined once and accessed by any page.
