Supabase UI is an open-source component library from the Supabase team. It provides a collection of UI components for integration with Supabase backend services. Built on top of the popular shadcn/ui system.
The primary function of Supabase UI is to offer pre-built components for common application features. These include authentication flows, file management connected to Supabase Storage, and elements for displaying real-time data updates.
You can use this library to accelerate the development of applications that utilize Supabase. It helps implement complex frontend features like user sign-up, login, file uploads, and real-time displays with less boilerplate code.

FAQs
Q: How does adding a component work?
A: You run an npx shadcn-ui@latest add <component_url> command in your terminal. This fetches the component definition, copies the source files into your project directory, and installs any necessary dependencies.
Q: Will adding components overwrite my existing files?
A: The command checks for file conflicts. If a file with the same name already exists, it will prompt you to either overwrite the existing file or skip adding the new one. It does not automatically overwrite files.
Q: Can I use Supabase UI in a project I’ve already started?
A: Yes, you can add Supabase UI components to existing projects. It’s recommended to commit your current changes to Git before running the add command so you can easily review the files added or modified.
Q: I already use shadcn/ui. What do I need to do?
A: If shadcn/ui is already configured in your project, you can directly use the npx shadcn-ui@latest add <component_url> command to add Supabase UI components without additional setup.
