Exploring Vue.prototype attributes and utilizing them

I'm facing a challenge while attempting to globally set a property using Vue.prototype.

This is what I currently have:

microsoftTeams.initialize();
microsoftTeams.getContext((context) => {
    Vue.prototype.$teamsContext = true;
});


new Vue({
    el: '#overview',
    components: {
        Index
    },
    data: {
       // add attributes here
    },
});

It seems like the issue lies in not being able to access Vue.prototype within the getContext call since $teamsContext is never initialized.

Is there a workaround for this situation?

Thank you

EDIT::

I've added some additional code.

Within the created() method of the Index component, I have a

console.log("CONTEXT", this.$teamsContext)

, which outputs CONTEXT undefined

Answer №1

This problem is quite intriguing.

If we assume that getContext operates asynchronously, one possible solution would be to load (mount) the app only after getContext has completed.

Here is a potential implementation:

// main.js

import Vue from "vue";
import App from "./App.vue";

Vue.config.productionTip = false;

let app;

const onResourceLoaded = () => {
  app.$mount("#app");
};

const customPlugin = {
  async install(Vue, options) {
    // Implement your asynchronous action here
    const resp = await fetch("https://jsonplaceholder.typicode.com/todos/1");
    const parsedResp = await resp.json();

    // Assign global property once action is complete
    Vue.prototype.$name = parsedResp.title;

    // Mount the app
    onResourceLoaded();
  }
};

Vue.use(customPlugin);

app = new Vue({
  render: h => h(App)
});

Note

If your asynchronous action is handled via a callback, you may need to wrap it within a promise like so:

const promisifyContext = () => new Promise(resolve => {
  microsoftTeams.getContext(context => {
    resolve(context);
  });
});

// Inside `install` function
const context = await promisifyContext();
Vue.prototype.$teamsContext = context;

onResourceLoaded();
