react-recaptcha-google

This component is created in order to make the experience of integrating Google ReCaptcha into React apps easier and smoother.

Currently, we are using ReCaptcha V2 here. ReCaptcha V3 is still in beta version; so, we will update our component when they release the stable version.

P.S. It will open the ReCaptcha window only when there are some doubts by Google; otherwise, it will automatically generate the recaptcha token.

Installation

npm install react-recaptcha-google --save

Usage

There are two components that you need to use.

$3

This function should be imported and called in the main (parent) component of your app. We recommend calling it in componentDidMount() of App.js.

``
import { loadReCaptcha } from 'react-recaptcha-google'

...

componentDidMount() {
loadReCaptcha();
}
`

#### invisible Recaptcha

Create a new component with the following code and give it a try!

`
import React, { Component } from 'react';
import { ReCaptcha } from 'react-recaptcha-google'

class ExampleComponent extends Component {
constructor(props, context) {
super(props, context);
this.onLoadRecaptcha = this.onLoadRecaptcha.bind(this);
this.verifyCallback = this.verifyCallback.bind(this);
}

componentDidMount() {
if (this.captchaDemo) {
console.log("started, just a second...")
this.captchaDemo.reset();
this.captchaDemo.execute();
}
}

onLoadRecaptcha() {
if (this.captchaDemo) {
this.captchaDemo.reset();
this.captchaDemo.execute();
}
}

verifyCallback(recaptchaToken) {
// Here you will get the final recaptchaToken!!!
console.log(recaptchaToken, "<= your recaptcha token")
}

render() {
return (


`


#### Visible / Normal Recaptcha

For having a visible ReCaptcha, you should make two minor changes on the above-mentioned code.
1. Replace the size prop value invisible (see the imported ReCaptcha component) with either normal or compact. Those will add a checkbox with 'I am not a robot' label.
2. Remove this.[captchaRef].execute() lines from your code.

##### Optional props

* data-theme - you can add theme prop with a value of either "dark" or "light"(default) to control the background theme of the visible ReCaptcha (when size is normal or compact)
* data-badge - you can send badge` prop with one of the following values: bottomright (default), bottomleft, inline. This will allowyou to reposition the ReCaptcha badge.
