# Sad App Monorepo

This repository is a monorepo which contains 2 workspaces, one a `React` UI

library and the other a `React` App which _consumes_ the UI library.

Unfortunately, because the UI library depends on `react@^18` and the App depends

on `react@^16`, these two projects in their current state are incompatible with

each other — even worse, we don't find this out until runtime when a call to

`useId()` explodes in the `Button` [component](./packages/ui/src/Button.jsx) 😢

The only reason this incompatibility is possible is because we allow each of

these workspaces to declare their own dependencies in their respective

`package.json`, which is why this is the **Sad App Monorepo**.

There are a few ways to address this issue, each with its own tradeoffs, but the

way that I prefer is to only have **one** version of a given dependency for the

_entire_ monorepo.

To see my preferred method of resolving this issue in action, see

[the companion repository for the "Happy App Monorepo"](https://github.com/andrewbrey/blog-monorepo-deps-happy-app).
