Setup a single source of dependencies and build tools for multiple plugins and themes

I've been working on a way to setup my tooling at the root of a WordPress project and easier manage dependencies that are, for the most part, shared across all my themes and plugins.

This includes:

• build tools for blocks
• compiling additional assets (css and js)
• lint and format tools for PHP, CSS and JS
• husky pre-commit tests

This is setup in such a way where I can build all my themes and plugins at the same time, or individual depending on what I'm working on. Here's an example of the work I've been doing in this area https://github.com/troychaplin/wp-dependency-manager

I think this could be valuable for folks running enterprise systems where they want to use a monorepo and simplify the build and maintenance of their projects.
