shadcn/ui is a collection of re-usable components that you can copy and paste into your apps. You can install different shadcn/ui components and use them to create a subscription component for your newsletter.
Getting started
To use the examples below, you'll need to install the Card, Button, Input, and Label components:
npx shadcn-ui@latest add button card input label
You may notice that we do not install the Form component. That's intentional; shadcn's form boilerplate pulls in React Hook Form and Zod, both of which are great libraries but overkill for simple subscription forms. If you've already installed them and want to use them, you can, but use the URL shown in the examples below for the action prop of Form.
In the examples, replace {username} with your Buttondown username.
