I try to fetch a json file in a custom plugin in Vue. But the prototype created in the plugin cannot be ready yet before other components attempt to use it in mounted().

So, what am I doing wrong? Couldn't find anything remarkable in StackOverflow.

app.js

import Vue from "vue"

const Url = require("@/plugins/Url")

Vue.use(Url)

Url.js

import djangoJsReverse from "django-js-reverse"

export default {
  async install(Vue, options) {
    Vue.PLUGIN_VERSION = "0.0.1"

    console.log("pre install")

    const response = await fetch("/jsreverse/")
    const data = await response.json()

    console.log("post install")

    Vue.prototype.$urls = djangoJsReverse(data)
  }
}
