Getting Started

This guide will walk you through the process of setting up your own component registry. It assumes you already have a project with components and would like to turn it into a registry.

If you're starting a new registry project, you can use the registry template as a starting point. We have already configured it for you.

Requirements

You are free to design and host your custom registry as you see fit. The only requirement is that your registry items must be valid JSON files that conform to the registry-item schema specification.

If you'd like to see an example of a registry, we have a template project for you to use as a starting point.

registry.json

The registry.json is the entry point for the registry. It contains the registry's name, homepage, and defines all the items present in the registry.

Your registry must have this file (or JSON payload) present at the root of the registry endpoint. The registry endpoint is the URL where your registry is hosted.

The shadcn CLI will automatically generate this file for you when you run the build command.

Add a registry.json file

Create a registry.json file in the root of your project. Your project can be a Next.js, Vite, Vue, Svelte, PHP or any other framework as long as it supports serving JSON over HTTP.

{
  "$schema": "https://ui.shadcn.com/schema/registry.json",
  "name": "acme",
  "homepage": "https://acme.com",
  "items": [
    // ...
  ]
}

This registry.json file must conform to the registry schema specification.

Add a registry item

Create your component

Add your first component. Here's an example of a simple <HelloWorld /> component:

import { Button } from "@/components/ui/button"

export function HelloWorld() {
  return <Button>Hello World</Button>
}

registry
└── new-york
    └── hello-world
        └── hello-world.tsx

Add your component to the registry

To add your component to the registry, you need to add your component definition to registry.json.

{
  "$schema": "https://ui.shadcn.com/schema/registry.json",
  "name": "acme",
  "homepage": "https://acme.com",
  "items": [
    {
      "name": "hello-world",
      "type": "registry:block",
      "title": "Hello World",
      "description": "A simple hello world component.",
      "files": [
        {
          "path": "registry/new-york/hello-world/hello-world.tsx",
          "type": "registry:component"
        }
      ]
    }
  ]
}

You define your registry item by adding a name, type, title, description and files.

For every file you add, you must specify the path and type of the file. The path is the relative path to the file from the root of your project. The type is the type of the file.

You can read more about the registry item schema and file types in the registry item schema docs.

Build your registry

Install the shadcn CLI

npm install shadcn@latest

Add a build script

Add a registry:build script to your package.json file.

{
  "scripts": {
    "registry:build": "shadcn build"
  }
}

Run the build script

Run the build script to generate the registry JSON files.

npm run registry:build

You can change the output directory by passing the --output option. See the shadcn build command for more information.

Serve your registry

If you're running your registry on Next.js, you can now serve your registry by running the next server. The command might differ for other frameworks.

npm run dev

Your files will now be served at http://localhost:3000/r/[NAME].json eg. http://localhost:3000/r/hello-world.json.

Publish your registry

To make your registry available to other developers, you can publish it by deploying your project to a public URL.

Guidelines

Here are some guidelines to follow when building components for a registry.

• Place your registry item in the registry/[STYLE]/[NAME] directory. I'm using new-york as an example. It can be anything you want as long as it's nested under the registry directory.
• The following properties are required for the block definition: name, description, type and files.
• It is recommended to add a proper name and description to your registry item. This helps LLMs understand the component and its purpose.
• Make sure to list all registry dependencies in registryDependencies. A registry dependency is the name of the component in the registry eg. input, button, card, etc or a URL to a registry item eg. http://localhost:3000/r/editor.json.
• Make sure to list all dependencies in dependencies. A dependency is the name of the package in the registry eg. zod, sonner, etc. To set a version, you can use the name@version format eg. zod@^3.20.0.
• Imports should always use the @/registry path. eg. import { HelloWorld } from "@/registry/new-york/hello-world/hello-world"
• Ideally, place your files within a registry item in components, hooks, lib directories.

Install using the CLI

To install a registry item using the shadcn CLI, use the add command followed by the URL of the registry item.

npx shadcn@latest add http://localhost:3000/r/hello-world.json

See the Namespaced Registries docs for more information on how to install registry items from a namespaced registry.
