Getting Started

Learn how to get setup and run your own component registry.

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. It's already configured for you.

registry.json

The registry.json file is only required if you're using the shadcn-svelte CLI to build your registry.

If you're using a different build system, you can skip this step as long as your build system produces valid JSON files that conform to the registry-item schema specification.

Add a registry.json file

Create a registry.json file in the root of your project. Your project can be a Next.js, Remix, Vite, or any other project that supports React.

registry.json

	{
  "$schema": "https://shadcn-svelte.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:

registry/hello-world/hello-world.svelte

	<script lang="ts">
  import { Button } from "$lib/components/ui/button/index.js";
</script>
 
<Button>Hello World</Button>

Note: This example places the component in the registry/ directory. You can place it anywhere in your project as long as you set the correct path in the registry.json file and you follow the registry/[NAME] directory structure.

	registry
└── hello-world
    └── hello-world.svelte

Important: If you're placing your component in a custom directory, make sure it can be detected by Tailwind CSS.

src/app.css

	@source "./registry/@acmecorp/ui-lib";

Add your component to the registry

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

registry.json

	{
  "$schema": "https://next.shadcn-svelte.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": "./src/lib/hello-world/hello-world.svelte",
          "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-svelte CLI

Note: the registry build command is currently only available in the shadcn@next version of the CLI.

npm i shadcn-svelte@next

Add a build script

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

package.json

	{
  "scripts": {
    "registry:build": "pnpm shadcn-svelte registry build"
  }
}

Run the build script

Run the build script to generate the registry JSON files.

npm run registry:build

Note: By default, the build script will generate the registry JSON files in static/r e.g static/r/hello-world.json.

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

Serve your registry

You can serve your registry by running the dev server.

npm run dev

Your files will now be served at http://localhost:5173/r/[NAME].json eg. http://localhost:5173/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.

Adding Auth

The shadcn-svelte CLI does not offer a built-in way to add auth to your registry. We recommend handling authorization on your registry server.

A common simple approach is to use a token query parameter to authenticate requests to your registry. e.g. http://localhost:5173/r/hello-world.json?token=[SECURE_TOKEN_HERE].

Use the secure token to authenticate requests and return a 401 Unauthorized response if the token is invalid. The shadcn-svelte CLI will handle the 401 response and display a message to the user.

Note: Make sure to encrypt and expire tokens.

Guidelines

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

The following properties are required for the block definition: name, description, type and files.
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:5173/r/editor.json
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-svelte CLI, use the add command followed by the URL of the registry item.

npx shadcn-svelte@next add http://localhost:5173/r/hello-world.json
