In a new post to his site Tomas Votruba shares his opinions on project structure and when he sees it appropriate to use a "monorepo" and when to use packages to compose your application.

Recently I gave a few talks about monorepo in PHP and how to integrate it to companies in a useful way. I'm very happy to see many people already use it and know what problems it solves.

Before monorepo hype takes over private PHP projects, I think you should know about its limits: When is the best time for you to go monorepo? When you gain less complexity while integrating it? How can you make the transition better? Is it really needed?

He starts off by describing some of the most common application structures including the monorepo, many-repository, and local package approaches. He sees each as an evolution on the previous and shares when he thinks the evolution makes the most sense (hint: it's about value). He ends the post by sharing a few final thoughts about monorepos and when they make sense for private projects versus public, open source projects.
