Create a Application Layout in Next.js and Cart Page

Our application code is still pretty bare at this point. For a shop application, we'll want a consistent Nav bar. We'll wrap that Nav around our existing code in _app.js to have a consistent nav across all pages.

In this lesson, I paste in the presentational code with all the Tailwind pre-written. This course isn't about crafting UIs so we skim past this part, I encourage you to dig around the Nav component if you want to see how I did that.
