Speed Up Jest Test Suites with Sharding

by | March 6, 2025 | DevOps, Post | 0 Comments

Large test suites in Node.js and React projects can significantly slow down your continuous integration (CI) pipeline. Jest already runs tests in parallel on a single machine using worker processes, but for very large suites you may need to parallelize across multiple machines. Jest 28 introduced a new –shard option that makes it easy to split your test suite into chunks and run them concurrently on separate CI runners.

NestJS + Next.js: Event Driven Architecture

by | February 20, 2025 | Lecture, NestJS, Next.js | 0 Comments

In this lecture, you'll learn how to build an event-driven architecture that seamlessly connects a NestJS backend with a Next.js UI using EventEmitter and Server-Sent Events (SSE).

By the end of this lecture, you'll have a fully functional event-driven system, where NestJS emits and processes events, and Next.js dynamically reacts to them in real-time. Perfect for applications requiring live notifications, background processing, and reactive UI updates. 🚀

Module Federation: Microservices for the Frontend

by | January 19, 2025 | Angular, Kubernetes, Lecture | 4 Comments

In this lecture, we dive deep into Module Federation and its role in creating a microservices architecture for the frontend. Using Nx, we explore how to structure and configure a modular frontend that enables independent deployments while maintaining seamless communication between micro-frontends.

We'll start with a hands-on example of dynamic federation, demonstrating how to load remote modules at runtime without hardcoding dependencies. Then, we’ll take it a step further by deploying our project to Kubernetes, where we dynamically mount a Module Federation manifest to enable flexible and scalable frontend microservices
