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 available via the [cli](/docs/cli).

To opt-out of TypeScript, you can use the `tsx` flag in your `components.json` file.

```json {10} title="components.json" showLineNumbers
{
  "style": "default",
  "tailwind": {
    "config": "tailwind.config.js",
    "css": "src/app/globals.css",
    "baseColor": "zinc",
    "cssVariables": true
  },
  "rsc": false,
  "tsx": false,
  "aliases": {
    "utils": "~/lib/utils",
    "components": "~/components"
  }
}
```

To configure import aliases, you can use the following `jsconfig.json`:

```json {4} title="jsconfig.json" showLineNumbers
{
  "compilerOptions": {
    "paths": {
      "@/*": ["./*"]
    }
  }
}
```
