A Solito project is typically two separate applications that share a monorepo (typically an Expo and a Next.js application)
You will need setup each project individually. We recommend using the Babel for your native app and Next.js via Babel for your Next.js app.
You can also spin up a Solito project with the setup already done:
npx create-solito-app@latest my-solito-app -t with-tailwind
Head over to the Solito Tailwind CSS Starter docs for more information.
