react-turnstile
A very simple React library for Cloudflare Turnstile.
Installation
npm i react-turnstile
Usage
import Turnstile, { useTurnstile } from "react-turnstile";
// ...
function TurnstileWidget() {
const turnstile = useTurnstile();
return (
<Turnstile
sitekey="1x00000000000000000000AA"
onVerify={(token) => {
fetch("/login", {
method: "POST",
body: JSON.stringify({ token }),
}).then((response) => {
if (!response.ok) turnstile.reset();
});
}}
/>
);
}
Turnstile tokens expire after 5 minutes, to automatically reset the challenge once they expire,
set the refreshExpired
prop to 'auto'
or reset the widget yourself using the onExpire
callback.
Reducing Layout Shift
The turnstile iframe initially loads as invisible before becoming visible and expanding to the expected widget size.
This causes Layout Shift and reduces your Cumulative Layout Shift score and UX.
This can be fixed with the fixedSize={true}
option, which will force the
wrapper div to be the specific size of turnstile.
Bound Turnstile Object
The Bound Turnstile Object is given as argument to all callbacks and allows you
to call certain window.turnstile
functions without having to store the widgetId
yourself.
function Component() {
return (
<Turnstile
execution="execute"
onLoad={(widgetId, bound) => {
// before:
window.turnstile.execute(widgetId);
// now:
bound.execute();
}}
/>
);
}

And the following callbacks:
| name | arguments | description | | ------------------- | --------------------------- | --------------------------------------------------- | | onVerify | token | called when challenge is passed | | onSuccess | token, preClearanceObtained | called when challenge is passed | | onLoad | widgetId | called when the widget is loaded | | onError | error | called when an error occurs | | onExpire | - | called when the token expires | | onTimeout | token | called when the challenge expires | | onAfterInteractive | - | called when the challenge becomes interactive | | onBeforeInteractive | - | called when the challenge no longer is interactive | | onUnsupported | - | called when the browser is unsupported by Turnstile |
The callbacks also take an additional BoundTurnstileObject
which exposes
certain functions of window.turnstile
which are already bound to the
current widget, so you don't need track the widgetId
yourself.
