Managing a new PHP project often begins with a “monorepo” approach for the sake of convenience and rapid development. However, as the Spacetraders.io client evolved to include a CLI, a Web GUI, and a suite of REST clients, the initial simplicity has turned into a tangled web of dependencies. It’s time to improve maintainability and allow for easier collaboration with some “Git Fission”—splitting our repository while preserving the commit history. > > This month, let’s see a technical roadmap you can adapt to deconstruct a monolithic repository into more modular components. I’ll show you how to use `git-filter-repo`, walk through renaming namespaces, and see how to use a newly split component as a dependency in Composer. by Oscar Merida
