Add it to your project

  1. 1

    Prepare your project

    You need Tailwind CSS and the @/import alias. If shadcn isn't set up yet, initialise it once:

    npx shadcn@latest init

    Then add the Nexus registry to your components.json (the registries key is the part that matters):

    {
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "default",
  "rsc": true,
  "tsx": true,
  "tailwind": {
    "css": "src/app/globals.css",
    "baseColor": "neutral",
    "cssVariables": true,
    "prefix": ""
  },
  "aliases": {
    "components": "@/components",
    "utils": "@/lib/utils",
    "ui": "@/components/ui",
    "lib": "@/lib",
    "hooks": "@/hooks"
  },
  "registries": {
    "@nexus-labs": "https://www.nexus-ui.com/api/registry/{name}"
  }
}

    Add the component

    Run this from your project root. It adds the component, the utilities it uses and its packages.

    npx shadcn@latest add @nexus-labs/password-strength

    Check what was added

    With the standard aliases, these files land in your project:

  return (
    <main>
