Why React forms need a backend
React form handling often requires complex state management and backend API setup. Formboost simplifies this with a simple API.
One form endpoint instead
Use fetch() or axios to POST form data to your Formboost endpoint. React will handle the UI, Formboost handles the backend.
Formboost is a form backend: the form endpoint receives the submission, screens it for spam, stores it and delivers it — the same for React as for any other frontend.
Setup in 4 Steps
Create a Formboost form endpoint
Store the endpoint ID in your React component or .env
Use fetch() to POST form data to the endpoint
Handle success/error states in your React component
Code Example
const [email, setEmail] = useState('');
const [message, setMessage] = useState('');
const handleSubmit = async (e) => {
e.preventDefault();
const response = await fetch('https://formboost.app/f/YOUR_ENDPOINT_ID', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ email, message })
});
if (response.ok) alert('Submitted!');
};
return (
<form onSubmit={handleSubmit}>
<input value={email} onChange={(e) => setEmail(e.target.value)} />
<textarea value={message} onChange={(e) => setMessage(e.target.value)} />
<button type="submit">Send</button>
</form>
