Setup a Micro-Frontend architecture in 15min with Vite!

Meidi Airouche on December 10, 2024

In a monolithic frontend architecture, a single codebase handles the entire user interface. While this can simplify initial development, it can bec...

This is great for SPAs, but if you guys just want a traditional website with different frameworks for functionality, try Astro instead

very good tutorial, but angular v19 do not have .\app\app.module.ts, in dist folder, vue generated header.umd.cjs file, react do not generate trending.umd.js.

I passed everything in ESM since it's more standard now. Thank you for the feedback <3

I added the repository with the overall code working (except for Angular) at the end of the article : github.com/mairouche/mfe-news-portal

This is amazing.
This is exactly what's happening in Astro behind the hood.
Correct me if I'm wrong.

To be Honest I discovered Astro with a previous comment and I'll deep dive into it. It looks like the same with Astro being maybe a bit more opinionated and closer to a framework than a library. But I'll look for it to see if I well understood

Couldnt integrate angular app, got error:

Uncaught SyntaxError: The requested module '/apps/highlights/dist/main.js' does not provide an export named 'mount' (at main.js:3:10)

has anyone make it run successful?

Depends on the version. Try with this in src/main.js:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';

function mount(el: HTMLElement) {
  const bootstrap = async () => {
    const appElement = document.createElement('app-highlights');
    el.appendChild(appElement);
    await platformBrowserDynamic().bootstrapModule(AppModule);
  };

  bootstrap().catch(err => console.error(err));
}

export { mount };
Enter fullscreen mode Exit fullscreen mode

got an abnormal main.js file under dist folder:

"use strict";(self.webpackChunkhighlights=self.webpackChunkhighlights||[]).push([[792],{429:(e,o,_)=>{}},e=>{e(e.s=429)}]);
Enter fullscreen mode Exit fullscreen mode

Do you mind sharing your full project code? this is really interesting...i have never seen a solution like this...

@lwz7512 Indeed, I was using module federation with old Angular versions. I will find out what's the best approach between, widgets, module federation or web component and propose it in an edit of the article.

Integrating multiple technologies within a micro frontend architecture is generally regarded as a suboptimal design choice. This approach can lead to significant performance issues, as it necessitates loading numerous technology libraries alongside each component, resulting in a bloated and resource-intensive application. Moreover, the complexity introduced by this multi-technology setup can make maintenance and management exceptionally challenging.

A more streamlined and efficient approach is to standardize on a single library or framework across the micro frontend ecosystem. This strategy offers several advantages:

  1. Improved performance due to reduced overhead from multiple libraries
  2. Simplified codebase that's easier to maintain and update
  3. Enhanced consistency in development practices and user experience
  4. Better team collaboration and knowledge sharing
  5. Reduced learning curve for new developers joining the project
  6. More straightforward integration and communication between micro frontends

By focusing on a unified technology stack, development teams can create more cohesive, performant, and maintainable micro frontend applications that align better with the core principles of this architectural pattern.

Agree. This is why I explained in the article that it can be a solution (temporary one) to shift from a framework to another smoothly here :

In a real life software growing through years, being able to handle multiple frameworks can be a smooth way to migrate from an old one to a new one whenever it's needed.

For example, in my experience, we transitionned form Angular to Vue step by step thanks to this approach. I'm not saying it's a desirable design but it's an existing one. Used in the appropriate context, it can bring value.

did you have any luck with precious angular versions , eg 18?

I succeed with module federation from Angular 16- but it's not that simple. I'm still testinfg things but Vue and React are Libraries whereas Angular, as a Framework, has it's own event, state, data management etc... So it's not that easy.
