Can an application be a monolith and microservices at the same time? Spoiler alert: yes!In this hands-on workshop, participants will build a full-stack application with TypeScript, React, and Jitar that blurs the traditional boundaries between monolithic and distributed architectures. Much like Schrödinger's famous thought experiment, the application's deployment model remains undecided during development. Only at deployment time is it determined whether the application runs as a monolith, a set of microservices, or something in between.The workshop begins with a simple full-stack monolith, with the frontend and backend deployed independently. From there, participants will evolve the system into a modular monolith composed of multiple applications and explore how the same codebase can be deployed either as a monolith or as a collection of microservices.Along the way, participants will learn practical techniques for designing scalable systems, defining logical and physical boundaries, creating distributable components, and applying practical deployment strategies.This workshop is ideal for full-stack developers, backend developers, and software architects.Before the workshop begins, participants should have Git, Node.js (version 24 or later), and a code editor installed on their laptop.
