Getting Started

Installation

Install the package


npm install @wire-ui/react


pnpm add @wire-ui/react


yarn add @wire-ui/react


bun add @wire-ui/react

Wire UI has no production dependencies. React 19 is a peer dependency.

Add peer dependencies

If you don’t already have React 19:


npm install react@^19 react-dom@^19


pnpm add react@^19 react-dom@^19


yarn add react@^19 react-dom@^19


bun add react@^19 react-dom@^19

Use a component


import { Button } from '@wire-ui/react'
 
export function SaveButton() {
  return (
    <Button type="submit" className="px-4 py-2 rounded bg-blue-600 text-white">
      Save changes
    </Button>
  )
}

Styling approach

Wire UI ships no CSS. All interactive state is exposed through data-* attributes. Target them with any CSS approach you prefer.


<Button className="
  px-4 py-2 rounded bg-blue-600 text-white transition-all
  [data-hover]:bg-blue-700
  [data-active]:scale-95
  [data-focus-visible]:ring-2 [data-focus-visible]:ring-offset-2
  [data-disabled]:opacity-50 [data-disabled]:cursor-not-allowed
">
  Submit
</Button>


/* button.module.css */
.button {
  padding: 0.5rem 1rem;
  border-radius: 0.375rem;
  background: #2563eb;
  color: white;
}
.button[data-hover] { background: #1d4ed8; }
.button[data-active] { transform: scale(0.95); }
.button[data-focus-visible] { outline: 2px solid #2563eb; }
.button[data-disabled] { opacity: 0.5; cursor: not-allowed; }


import styles from './button.module.css'
<Button className={styles.button}>Submit</Button>


.button[data-hover]         { background: #1d4ed8; }
.button[data-active]        { transform: scale(0.95); }
.button[data-focus-visible] { outline: 2px solid #2563eb; }
.button[data-disabled]      { opacity: 0.5; cursor: not-allowed; }

Compound components

Complex components use the Component.Part pattern. You compose the markup yourself:


import { Input } from '@wire-ui/react'
 
<Input.Root value={value} onChange={setValue}>
  <Input.Label>Email address</Input.Label>
  <Input.Field type="email" placeholder="you@example.com" />
  <Input.Error />
</Input.Root>

You control the DOM order. Need the error above the field? Swap them. Need a wrapper div between label and field? Add it. Wire UI never dictates structure.

Validation pattern

Wire UI components do not validate internally. You own validation — set invalidType when your logic determines the field is invalid:


const [email, setEmail] = useState('')
const [invalidType, setInvalidType] = useState('')
 
function handleSubmit(e: React.FormEvent) {
  e.preventDefault()
  if (!email) setInvalidType('required')
  else if (!email.includes('@')) setInvalidType('email')
  else setInvalidType('')  // clear the error
}
 
<Input.Root
  value={email}
  onChange={setEmail}
  invalidType={invalidType}
  errorMessage={{
    required: 'Email is required',
    email: 'Enter a valid email address',
  }}
>
  <Input.Label>Email</Input.Label>
  <Input.Field type="email" />
  <Input.Error />
</Input.Root>

TypeScript

All prop types are exported:


import type {
  ButtonProps,
  InputRootProps,
  TextareaRootProps,
  PasswordRootProps,
  ModalRootProps,
  AccordionRootProps,
  SearchOption,
  Size,
  Status,
} from '@wire-ui/react'
