Improve your architecture and CI pipeline times with Nx projects

Adopting a monorepo approach with Nx requires understanding and restructuring to maximize benefits, such as reducing CI run times and costs. An example from a major US sports retailer demonstrates the challenges and improvements possible with this approach, as their initial migration resulted in long CI times and low cache hit rates, but by adhering to best practices, they significantly reduced these times. Effective monorepo management involves creating separate projects for shared code and applications, enabling faster task execution, better caching, and parallelization. This strategy involves moving common elements like UI features or utility functions into dedicated libraries, which enhances consistency and further reduces build times. While a monorepo structure does not automatically solve CI pipeline issues, evaluating and restructuring architecture with best practices can lead to substantial improvements in build efficiency.
