A universal monorepo using yarn workspaces

This monorepo uses Yarn workspaces and TypeScript to support a modular React Native project.

The core idea is to isolate the JavaScript app code from the platform configurations (native code + the app bundlers like Metro and Webpack).
This isolation happens by using different workspaces: We have an app workspace for the JavaScript app code, a mobile workspace for the React Native mobile configuration, a macos workspace for the React Native macOS configuration, and so on.

We fully embrace Yarn nohoist to allow using different versions of React Native on each platform (which is recommended but not required), simplifying the adoption of new React Native updates.
Thanks nohoist, each platform workspace (mobile, macos, etc.) can depend on any React Native version, regardless of what version the other platform workspaces are using. For example, we can use react-native@0.67.1 on the mobile app and react-native@0.64.3 on the macOS app — as long as the JavaScript app code supports both versions.
This approach promotes gradual React Native updates over updates in lockstep.

⚠️ Please notice that I'm not saying this is the right way to do React Native monorepos. This is just an approach that I enjoy using on larger codebases :)
