Once you 

Exposed your Module

You can dynamically load it to your app, like you load any internal module

@anfibiacreativa

import { SomeProvider } from "@shared-context/shared-providers";
import React from "react";

const ExposedModule = React.lazy(() => import("remote1/ExposedModule"));

const App = () => (
  <div>
    <h1>Remote Micro Frontend Example</h1>
    <SomeProvider.Provider value="value">
      <React.Suspense fallback="Loading Remote...">
        <ExposedModule />
      </React.Suspense>
    </SomeProvider.Provider>
  </div>
);

export default App;
