Micro-Frontends in the trenches

“We adopted micro-frontends… and suddenly authentication became everyone’s problem.”

That sentence alone has probably cost teams months of rework, endless Slack threads, and architecture diagrams that aged badly after the first production incident.

In the latest episode of Micro-Frontends in the Trenches, I sit down with Chris Fryer to unpack the realities behind his #microfrontends Framework, the evolving Module Federation ecosystem, and much more

☢️ WARNING: This is not a theoretical conversation.

Listen to the episode and let me know what challenged your perspective the most.

In this episode, I’m joined by Boris Besemer from Vercel to unpack what it really takes to start a migration to micro-frontends without turning it into a never-ending transformation.
We focus on the very first steps teams should take: how to identify the right starting point and how to avoid the most common early mistakes that slow teams down or create unnecessary complexity.
A big part of the conversation explores how the Vercel platform can simplify platform engineering during a migration.
We discuss how tooling, deployment workflows, preview environments, and developer experience can reduce cognitive load while multiple teams progressively move toward a micro-frontend architecture.

I don't think you need to know more than the name of the guest to love this episode: Sam Newman, author of Building Microservices and other best sellers on distributed systems.

This is an episode you don't want to miss where I talk about micro-frontends with Sam drawing parallelisms between the 2 layers of a distributed system.

Enjoy this fantastic episode

In this episode of Micro-Frontends in the Trenches, I talk with Jeremy Colin (ex-Zalando) about the journey that led to Tailor.js and later Mosaic, two pioneering frameworks that shaped how micro-frontends are built at scale.Jeremy shares the technical challenges, trade-offs, and lessons learned while building these platforms, and why platform engineering is essential for making micro-frontends practical in real-world organizations.We dive into:- The story behind Tailor.js and its role in Zalando’s architecture.- How Mosaic evolved and why it mattered.- The hidden complexities of adopting micro-frontends.- Why platform engineering is key to simplifying and sustaining the practice.I highly encourage all of you to listen to this episode that is part of the micro-frontend history!

We’ve been cooking something new—Remote Components.Imagine pushing a tiny change to your e-commerce site like updating a free shipping banner and having to wait hours for the entire site to build and test. That’s the reality of traditional monolithic frontends, where even the smallest updates can ripple across the codebase, slowing teams down and widening the blast radius for potential problems.Vercel is changing the game with micro-frontends providing an unmatched developer experience so farIn this episode you’ll learn how Vercel micro-frontends implementation can:- Speed up build and deploy times- Reduce risks when releasing features- Empower teams to ship independently without stepping on each other’s toes
