Imports

Unlike the original shadcn/ui for React, where the full components can exist in a single file, components in this port are split into multiple files. This is because Svelte doesn't support defining multiple components in a single file, so utilizing the CLI to add components will be the optimal approach.

The CLI will create a folder for each component, which will sometimes just contain a single Svelte file, and in other times, multiple files. Within each folder, there will be an index.ts file that exports the component(s), so you can import them from a single file.

For example, the Accordion component is split into four .svelte files:

• Accordion.svelte
• AccordionContent.svelte
• AccordionItem.svelte
• AccordionTrigger.svelte

They can then be imported from the accordion/index.ts file like so:

	import * as Accordion from '$lib/components/ui/accordion"
// or
import {
  Accordion,
  AccordionContent,
  AccordionItem,
  AccordionTrigger
} from "$lib/components/ui/accordion"

Regardless of the import approach you take, the components will be tree-shaken by Rollup, so you don't have to worry about unused components being bundled into your app.

TypeScript

This project and the components are written in TypeScript. We recommend using TypeScript for your project as well.

However, we provide a JavaScript version of the components as well. The JavaScript version is only available via the CLI.

Opt-out of TypeScript

To opt out of TypeScript, set the typescript flag to false in your components.json file.

	{
  "style": "default",
  "tailwind": {
    "config": "tailwind.config.js",
    "css": "src/app/globals.css"
  },
  "typescript": false,
  "aliases": {
    "utils": "$lib/utils",
    "components": "$lib/components"
  }
}

To configure import aliases, you need to create a jsconfig.json:

	{
  "compilerOptions": {
    "paths": {
      "$lib/*": ["./src/lib/*"]
    }
  }
}

ESLint configuration

If you are using ESLint, some components may trigger false positives depending on your ESLint configuration. For example, you could end up with lint errors when components define $$Props to specify the type for $$restProps as $$Props is not directly used in the rest of the component.

To ignore these linting errors, you can modify your ESLint configuration.

One option is to add a .eslintrc file in the directory where you define your components, $lib/components/ui for example:

	{
  "rules": {
    "@typescript-eslint/no-unused-vars": [
      "warn",
      {
        "argsIgnorePattern": "^_",
        "varsIgnorePattern": "^\$\$(Props|Events|Slots|Generic)$"
      }
    ]
  }
}

The main benefit of adding an additional .eslintrc file just to $lib/components/ui is that you will not affect how ESLint functions for the rest of your project. Only your svell components will ignore these false positives.

If this is not important to you, then another option is to use a similar rule override in your global ESLint configuration file, usually .eslintrc.cjs. For inspiration, please refer to this gist.
