React 16.13 (could be lower), TypeScript, and Reach-Router 1.3.x.x. I'll be using CSS-In-JS (Not required) and React 16.13. No hooks are needed, but components are functional. You can use any CSS-in-JS approach to display breadcrumbs in React. Re-Reach Router allows us to have as many Routers as we'd like. By specifying it with the main navigation, we'll be calling it 'Reach-router'
