Scaling Frontend Development with Single-Spa Micro-Frontends

Hey there! Have you ever worked on a huge frontend project where things started getting a bit… chaotic? You know, when one small change on the homepage somehow breaks the entire checkout process? It happens. That’s where micro-frontends come to the rescue. And in this article, we’ll explore how you can use single-spa micro-frontend framework to build a micro-frontend architecture, with a step-by-step guide that you can totally try out!

Ready? Let’s dive in!

So, What’s a Micro-frontend Anyway?
Imagine splitting your huge app into smaller pieces, where each piece (or micro-frontend) can be built, deployed, and managed independently. Each team gets their own “mini-app” to work on, and all of these mini-apps magically come together to form your whole app.

Cool, right? It’s like microservices, but for the frontend!

Why Use Single-spa?
Now, you might be wondering, “How do I get all these mini-apps to work together smoothly?” That’s where Single-spa comes in. It’s like the glue that holds all these tiny apps together, making sure they mount and unmount at the right time. (FYI ; There are couple of alternatives exist that support for micro-frontend architecture but in this article let’s stick to single-spa)

Here’s what Single-spa helps you do:

  • Manage multiple frameworks (like React, Vue, Angular) on one page or application.
  • Load different mini-apps when users visit different parts of your site.
  • Let each micro-frontend live its own life but still play well with others.
  • Lazy load code for improved initial load time

Sounds neat? Let’s build something with it!
