The Twelfth Factor Correction

This is a series of notes on the Essay https://12factor.net/codebase

I. Codebase: One codebase tracked in revision control, many deploys

A twelve-factor app is always tracked in a version control system, such as Git, Mercurial, or Subversion. A copy of the revision tracking database is known as a code repository, often shortened to code repo or just repo.
A codebase is any single repo (in a centralized revision control system like Subversion), or any set of repos who share a root commit (in a decentralized revision control system like Git).

12 factor app specifically argues against a monorepo. Their argument is that the shared code should be refactored out into dependencies, as in Factor II. This is a valid argument, but the overhead of separating dependencies and testing them individually is not worth the cost for most small teams. The pattern of building a series of components of a distributed system from a common codebase - Of having one monorepo that produces m
