The development of multiple repositories is not always an easy task. If you want to offer a high-quality and evolving application, sooner or later, there is a need to make the same changes in several packages. This can be a simple change in the documentation of a few packages or the adoption of new coding standards. During the development of Shopsys Framework, we have come to the point where thousands of hours were allocated for development across multiple repositories and for development of new packages. And it was this moment when we decided to choose the way of monorepo. Upgrade several packages to a new version of PHPUnit? Why not! Change of method in API used across multiple packages? Super easy! Of course, monorepo is not for everyone. We will show you, why it can be useful to use monorepo and what was the way to the monorepo in Shopsys Framework.
