single-spa VS piral

Single-SPA Framework - One of the most popular choices. It has a large community behind it and offers robust routing and lifecycle management for microapps. Ref - https://single-spa.js.org/

Joel Denning is the visionary behind single-spa, boasting profound insights into the true mechanics of the web and is, in my view, a pioneer in micro frontend architecture. I highly recommend checking the single-spa website and his YouTube channel. While the videos might appear dated at first glance, rest assured, Joel is ahead of his time, and the content remains incredibly relevant today.

You got me curious and I found that single spa is something new to me - if I read https://github.com/single-spa/single-spa then I reckon you can use Svelte(Kit) in such framework - like you can use angular etc

I’ve actually done that “web components as the interoperability layer”!

It was this old angular 1.8 app with new features being written in angular-hybrid-ized angular 8. Ripping out angular-hybrid and separating the angular 1.8 routes from the modern angular routes was difficult, but now they were totally separate.

The only thing linking them together was an object with some RXJS streams in it for state, and a little in-house wrapper “app” who just loaded one component or another depending on the URL and a hash of routes for config. (I’d probably use SingleSPA [1] now. Same thing really.)

We could deploy them separately since the build just ends up being another JS file somewhere that just gets included with a script tag at runtime. No version bumping! No big mega build!

We started replacing the remaining “old” routes 1 by 1 with a “new” counter part. That was the easiest part, and went at a pace devs were comfortable with (fast enough) and business folk could tolerate. (modular enough to not HAVE to be done all at once)

Last I checked, the angular 1.8 stuff is gone years ago. :)

Module Federation is not the unique solution, for example single-spa

You may want to look into using single-spa to run Vue 2 and Vue 3 side by side while you're migrating. Once your app is fully converted, you can stop using single-spa

Single-SPA and module federation are potent tools for building scalable micro-frontends. Single-spa provides a framework for building a modular front-end application. It allows lazy loading of micro-frontends, which helps improve the application's performance. In contrast, module federation enables communication and dependency sharing between different micro-frontends. It reduces code duplication, which can help with scaling an application.

Since micro-frontend allows us to develop applications individually, this also means you can use different frameworks and libraries together to develop each section of this application. Of course, this will have some advantages and disadvantages. If you are using different technologies to serve different parts of the application, it won't be so easy to move developers within teams. However, the door is open, and if you want to do something like that, you could use something like Single SPA, or some other, to help you organize and connect the different technologies into a larger application.

Piral Framework - Focused on developer experience with features like a visual UI editor, live previews and hot module replacement. Ref - https://piral.io/

Micro-frontend applications have become increasingly popular among developers thanks to their many advantages. It helps create modular and maintainable applications capable of handling complex business needs. As with any technology, implementing micro-frontends poses challenges, such as ensuring consistent APIs. But, with tools like Piral, developers can easily create and scale micro-frontend applications.

Piral: implements isolated components called pilets. Pilets are modules that bundle content and behavior.

I've prepared a demo project on the basis of Piral. The running demo can be found at the Piral samples organization on GitHub. Running the demo locally does not look very spectacular.

3) Piral: Piral is a framework for next-gen portal applications.

For the command line tooling of our micro frontend framework Piral we needed to be sure that it properly runs. This includes

The idea of writing a book about micro frontends was born in mid 2019 when Piral was born out of smapiot's open-source efforts. We've been leading and assisting to micro frontend implementations for a while, and our intention was to put together an (almost) ideal pattern into an open-source framework.

Therefore, for the example, I've picked a rather fancy way to "loosely" get the micro frontends at runtime using a file called feed.json, which is created at build-time using the information which micro frontends (called pilets in this case, because I am using the Piral framework) are actually available. Therefore, just adding, e.g., a third micro frontend easily works without touching the app-shell package.
