   Serving Millions of Pages with Micro-Frontends: Inside The Weather Company

   In this episode of Micro-Frontends in the Trenches, Luca sits down with Noel Madali, Consumer Product Principal Architect at The Weather Company, to unpack a decade-long architectural evolution that took weather.com from an Angular and Drupal stack all the way to Next.js on Vercel.Noel has spent around ten years at The Weather Company, starting as a senior engineer and helping modernise the platform through several cloud migrations along the way, from Akamai and Drupal to Kubernetes on AWS, then IBM Cloud, and finally back to AWS with parts of the estate now running on Vercel. He walks through why the micro-frontend model resonated so naturally with their existing backend-for-frontend pattern, how they split weather.com by path across web, CMS, and API projects, and how labs.weather.com hosts over twenty experimental micro-frontends under a single group.The conversation gets into the real trade-offs of operating at this scale. Noel explains their "split brain" migration approach using Akamai in front of Vercel, the many flavours of caching they have wrestled with, and how they lean on React Server Components, ISR, and the newer cache components to serve millions of high-cardinality pages without triggering millions of revalidations. He and Luca also dig into the developer experience wins from Vercel's micro-frontend tooling, the chicken-and-egg gotchas of adding new projects into a git-flow process, how they layer Caddy on top of the built-in proxy for local development, and where remote micro-frontends fit into their roadmap with a shared footer as the likely first candidate.If you care about micro-frontends, Next.js at scale, caching strategy, or the messy reality of a multi-year platform migration, this one is packed with hard-won lessons from the trenches.This season of Micro-Frontends in the Trenches is brought to you by Vercel.

   How to build real-time applications using micro-frontends with Peter Eijgermans

   In this episode of Micro-Frontends in the Trenches, Luca Mezzalira sits down with Peter Eijgermans to unpack a five-year journey building Spoorviewer, the real-time dashboard powering operations at the Dutch Railways (NS / ProRail). Peter walks through how four teams modernized a slowing Angular monolith into a dashboard-style shell hosting five remote applications, loaded dynamically at runtime via Module Federation. You'll hear what worked, what didn't, and why the first attempt with Web Components (Custom Elements) failed to deliver on performance. CHAPTERS 00:00 Cold open: shipping without fear 01:26 Welcome and introductions 03:02 Meet Peter: full-stack, real-time data, and OIDC 05:16 Spoorviewer: a dashboard, not a page-based app 07:22 The five remote apps: Spoorzicht, Plan, Baanvak, Track Occupancy, Maintenance 10:34 Why micro-frontends? The organizational and technical breaking point 12:47 The performance trap of Custom Elements 14:54 Switching to Module Federation: Lighthouse 30 → 75 16:50 Domain-Driven Design and identifying overlapping boundaries 20:11 Recap: shell, lazy loading, DDD, and team independence 23:30 WebSockets aligned to bounded contexts 26:46 How developers felt about the move to micro-frontends 28:11 Guardrails: framework alignment, versioning, shared libraries 31:14 From client-side OIDC to a Backend-for-Frontend "Lego brick" 34:27 Drawbacks and lessons learned along the way 36:41 Architecture surfaces friction, it doesn't create it 39:17 AI on the horizon: predicting train delays 40:39 AI in the developer workflow 42:31 Closing reflections: start with good design 43:21 Wrap-up and outro

   A new framework for building micro-frontends with Chris Fryer

   “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 (https://www.linkedin.com/#) 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.

   Migrating to micro-frontends with Boris Besemer from Vercel

   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.
