How to Share a Leaflet Map Instance Across Multiple Vue 2 Components?

Background: I'm building a web application using Vue 2 and Leaflet. I'm trying to share a single Leaflet map instance across multiple components in my application.

Issue: I'm looking for a way to create a Leaflet map instance in one place and access and use it across multiple components in the entire application.

Code Example: This is a method I have tried, but I don't know if this way of writing is appropriate. Maybe there is a better way:

App.vue

  provide() {
    return {
      parent: this
    };
  },
  mounted() {
 this.map = L.map('map',{})
}

components

 inject: ["parent"]

Is there a more appropriate way?
