# react-google-invisible-recaptcha #
A React component which is interested in only Google invisible reCAPTCHA.
* Support multiple reCAPTCHA widgets on one page.
* Support React hooks.
* Support Typescript.
## Migration from 0.x to 1.0.0
```js
// Version 0.x
this.recaptcha = ref} ... />
// this.recaptcha.execute invokes the reCAPTCHA check.
// Version 1.0.0
const refCaptcha = React.useRef(null) // or React.createRef().
// refRecaptcha.current.callbacks.execute invokes the reCAPTCHA check.
// ^^^^^^^^^^^^^^^^^^
```
## [Demo][demo] ##
Type something in an input box and click the button to submit data. The value is then checked to make up example client-side validation. Only valid input triggers reCAPTCHA. Since the reCAPTCHA is invisible, it proceeds most likely as if none is attached. You will only be present the figure of the reCAPTCHA when Google hesitates to tell your identity.
When reCAPTCHA is resolved, the demo page shows the result token for demo purpose. In a real application, it should be used with a HTTP request targeting at `https://www.google.com/recaptcha/api/siteverify?secret=&response=` on the server to validate the reCAPTCHA result before any sensitive operation is performed. Checking input values derived from clients on the server imporves security as well.
## Example ##
See the `example/` folder for an example.

```sh
// 1.0.0 prerelease.
npm install react-google-invisible-recaptcha@next --save
```
