Usage

tsx

"use client";

import { useState } from "react";
import { FileDropzone } from "mizu-ui";

export function Example() {
  const [files, setFiles] = useState<File[]>([]);
  return (
    <>
      <FileDropzone
        label="Attach artwork"
        accept="image/*,.svg"
        multiple
        onFilesChange={setFiles}
      />
      <p>{files.map((f) => f.name).join(", ")}</p>
    </>
  );
}

It starts with "use client" because it keeps state or passes functions to components, so it pastes into a Next.js page as it is. Other React setups ignore the directive.

Source & setup

Add this component to your project with the shadcn CLI. The command copies its source into your configured UI directory, with base.css, Mizu’s tokens, and the stylesheets that hold its rules. Each rule lives in one stylesheet, so components you add together never repeat CSS. In a project without a components.json, run npx shadcn@latest init 0xuser64bit/mizu/preset first: plain init installs shadcn’s theme into your global CSS. Then load the fonts.

npx shadcn@latest add 0xuser64bit/mizu/file-dropzone

Every component imports from its own path, its name in kebab case. To paste the example, replace its mizu-ui import with:

tsx

import { FileDropzone } from "@/components/ui/mizu/file-dropzone";

For npm imports, import mizu-ui/styles.css once. Fonts are optional via mizu-ui/fonts.css. Override --mizu-* tokens or use className for local styling. Uses native React and CSS; install the package peers for root imports. A Client Component: its source starts with “use client”.

Props

Prop	Type	Default	Description
onFilesChange	(files: File[]) => void	—	Receives validated files; upload remains your responsibility.
accept	string	—	Comma-separated extensions or MIME patterns.
maxSize	number	10485760	Bytes per file.
multiple	boolean	false	Allow multiple files.

Accessibility

Keyboard users open the native file dialog with the browse button. Validation errors name the rejected files. Client checks do not replace server validation.

Motion

CSS transitions explain state changes. Reduced motion removes travel.
