# 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. ### 1. Use `loadReCaptcha()` to initialize the ReCaptcha 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(); } ``` ### 2. Use `ReCaptcha` to integrate ReCaptcha in a particular component #### 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 (

{/* You can replace captchaDemo ref with whatever works for your component */} {this.captchaDemo = el;}} size="invisible" render="explicit" sitekey="your_site_key" onloadCallback={this.onLoadRecaptcha} verifyCallback={this.verifyCallback} />


          1. Add your site key in the ReCaptcha component. 

          2. Check console to see the token.

); }; }; export default ExampleComponent; ``` #### 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.
