Trap 1: Reduced risk of configuration drift
Multiple repos can also have configuration management; monorepo doesn't inherently reduce drift.
Trap 2: Faster clone times due to smaller repository size
Monorepos are typically larger, leading to slower clones.
Easier code sharing and refactoring across projects
Shared code is in the same repo, simplifying updates.
Reduced risk of configuration drift
Why wrong: Multiple repos can also have configuration management; monorepo doesn't inherently reduce drift.
Simplified dependency management across projects
All code in one repo makes it easier to manage cross-project dependencies.
Faster clone times due to smaller repository size
Why wrong: Monorepos are typically larger, leading to slower clones.
