Fast-tracking quality for releasing hundreds of React Apps.

A case study explores the Streaming company's journey of building automated testing layers within a complex, multidimensional React monorepo and achieving quality contribution feedback within minutes.

How we transformed a React monolith into multiple apps inside one codebase.

You always start small: one product, one team, one stakeholder. But once you succeed and need to scale, your original frontend architecture might not be ready for what comes next. As our Sales Process Orchestration Platform expanded to support multiple products and sales channels, our original monolithic application became a bottleneck.
In this talk, I'll share how we transitioned to a domain‑driven, multi‑app architecture while deliberately keeping a single React codebase. You'll see how we applied Domain‑Driven Design concepts on the frontend, structured clear boundaries between sales channels, and used Nx to orchestrate builds, enforce architecture rules, and keep teams moving independently without losing shared foundations.

Providing a robust and unobtrusive Dev Experience to work in a monorepo is a challenging endeavour. Many teams experience resistance with monorepos due to the lack of solid tech to support it at scale.

This talk will showcase how Nx can truly make working with monorepos a joyful reality that combines a higher built-in quality with a higher productivity as well.

In the past year, we went from zero to 20,000 lines of Playwright tests, pushing its capabilities beyond basic end-to-end testing. This talk will explore the challenges we encountered as we scaled our Playwright setup and how we solved them, thanks to the robust ecosystem and team creativity.
