Overview

The most basic usage of React Turnstile involves importing the component and providing your Cloudflare sitekey. This guide covers common usage patterns and best practices.

​
Simple Implementation

Here’s the simplest way to add Turnstile to your React component: 
import { Turnstile } from '@marsidev/react-turnstile'

function MyForm() {
  return (
    <form>
      <input type="email" placeholder="Email" />
      <Turnstile siteKey="1x00000000000000000000AA" />
      <button type="submit">Submit</button>
    </form>
  )
}
Replace 1x00000000000000000000AA with your actual Cloudflare Turnstile sitekey. You can obtain one from the Cloudflare Dashboard.

​
Handling Success Callback

Capture the verification token when the challenge is successfully completed: 
import { Turnstile } from '@marsidev/react-turnstile'
import { useState } from 'react'

function MyForm() {
  const [token, setToken] = useState<string>()

  return (
    <form>
      <input type="email" placeholder="Email" />
      <Turnstile
        siteKey="1x00000000000000000000AA"
        onSuccess={(token) => {
          console.log('Verification successful! Token:', token)
          setToken(token)
        }}
      />
      <button type="submit" disabled={!token}>
        Submit
      </button>
    </form>
  )
}

​
Complete Form Integration

Here’s a complete example with form submission and error handling: 
import { Turnstile } from '@marsidev/react-turnstile'
import { useState } from 'react'

function ContactForm() {
  const [token, setToken] = useState<string>()
  const [status, setStatus] = useState<'idle' | 'submitting' | 'success' | 'error'>('idle')

  const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
    e.preventDefault()
    
    if (!token) {
      alert('Please complete the verification')
      return
    }

    setStatus('submitting')

    try {
      const formData = new FormData(e.currentTarget)
      const response = await fetch('/api/contact', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
          email: formData.get('email'),
          message: formData.get('message'),
          turnstileToken: token
        })
      })

      if (response.ok) {
        setStatus('success')
      } else {
        setStatus('error')
      }
    } catch (error) {
      setStatus('error')
    }
  }

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="email"
        name="email"
        placeholder="Email"
        required
      />
      <textarea
        name="message"
        placeholder="Message"
        required
      />
      <Turnstile
        siteKey="1x00000000000000000000AA"
        onSuccess={setToken}
        onError={() => setToken(undefined)}
        onExpire={() => setToken(undefined)}
      />
      <button type="submit" disabled={!token || status === 'submitting'}>
        {status === 'submitting' ? 'Submitting...' : 'Submit'}
      </button>
      {status === 'success' && <p>Form submitted successfully!</p>}
      {status === 'error' && <p>Error submitting form. Please try again.</p>}
    </form>
  )
}

  options={{
    theme: 'dark' // or 'light', 'auto'
  }}
/>

​
Size

Control the widget size: 
<Turnstile
  siteKey="1x00000000000000000000AA"
  options={{
    size: 'compact' // or 'normal', 'flexible'
  }}
/>

<Turnstile

/>

​
Lifecycle Callbacks

React to various widget events: 
<Turnstile
  siteKey="1x00000000000000000000AA"
  onSuccess={(token) => console.log('Success:', token)}
  onError={(error) => console.error('Error:', error)}
  onExpire={() => console.log('Token expired')}
  onBeforeInteractive={() => console.log('Before interactive')}
  onAfterInteractive={() => console.log('After interactive')}
  onUnsupported={() => console.log('Browser not supported')}
  onTimeout={() => console.log('Widget timed out')}
/>
