React-google-recaptcha: Component Wrapper for Google ReCAPTCHA

react-google-recaptcha

React component for Google reCAPTCHA v2.

Installation

npm install --save react-google-recaptcha

Usage

All you need to do is sign up for an API key pair. You will need the client key then you can use <ReCAPTCHA />.

The default usage imports a wrapped component that loads the google recaptcha script asynchronously then instantiates a reCAPTCHA the user can then interact with.

Code Example:

import ReCAPTCHA from "react-google-recaptcha";

function onChange(value) {
  console.log("Captcha value:", value);
}

ReactDOM.render(
  <ReCAPTCHA
    sitekey="Your client site key"
    onChange={onChange}
  />,
  document.body
);

Component Props

Properties used to customise the rendering:

NameTypeDescription
asyncScriptOnLoadfuncoptional callback when the google recaptcha script has been loaded
badgeenumoptional bottomright, bottomleft or inline. Positions reCAPTCHA badge. Only for invisible reCAPTCHA
hlstringoptional set the hl parameter, which allows the captcha to be used from different languages, see [reCAPTCHA hl]
isolatedbooloptional For plugin owners to not interfere with existing reCAPTCHA installations on a page. If true, this reCAPTCHA instance will be part of a separate ID space. (default: false)
onChangefuncThe function to be called when the user successfully completes the captcha
onErroredfuncoptional callback when the challenge errored, most likely due to network issues.
onExpiredfuncoptional callback when the challenge is expired and has to be redone by user. By default it will call the onChange with null to signify expired callback.
sitekeystringThe API client key
sizeenumoptional compact, normal or invisible. This allows you to change the size or do an invisible captcha
stokenstringoptional set the stoken parameter, which allows the captcha to be used from different domains, see [reCAPTCHA secure-token]
tabindexnumberoptional The tabindex on the element (default: 0)
typeenumoptional image or audio The type of initial captcha (defaults: image)
themeenumoptional light or dark The theme of the widget (defaults: light). See [example][docs_theme]

Component Instance API

The component instance also has some utility functions that can be called. These can be accessed via ref.

  • getValue() returns the value of the captcha field
  • getWidgetId() returns the recaptcha widget Id
  • reset() forces reset. See the JavaScript API doc
  • execute() programmatically invoke the challenge
  • executeAsync() programmatically invoke the challenge and return a promise that resolves to the token or errors(if encountered).
    • alternative approach to execute() in combination with the onChange() prop - example below

Example:

const recaptchaRef = React.createRef();
...
onSubmit = () => {
  const recaptchaValue = recaptchaRef.current.getValue();
  this.props.onSubmit(recaptchaValue);
}
render() {
  return (
    <form onSubmit={this.onSubmit} >
      <ReCAPTCHA
        ref={recaptchaRef}
        sitekey="Your client site key"
        onChange={onChange}
      />
    </form>
  )
}

Invisible reCAPTCHA

▶ Codesandbox invisible example

See the reCAPTCHA documentation to see how to configure it.

With the invisible option, you need to handle things a bit differently. You will need to call the execute method yourself.

import ReCAPTCHA from "react-google-recaptcha";

const recaptchaRef = React.createRef();

ReactDOM.render(
  <form onSubmit={() => { recaptchaRef.current.execute(); }}>
    <ReCAPTCHA
      ref={recaptchaRef}
      size="invisible"
      sitekey="Your client site key"
      onChange={onChange}
    />
  </form>,
  document.body
);

Additionally, you can use the executeAsync method to use a promise based approach.

import ReCAPTCHA from "react-google-recaptcha";


const ReCAPTCHAForm = (props) => {
  const recaptchaRef = React.useRef();

  const onSubmitWithReCAPTCHA = async () => {
    const token = await recaptchaRef.current.executeAsync();

    // apply to form data
  }

  return (
    <form onSubmit={onSubmitWithReCAPTCHA}>
      <ReCAPTCHA
        ref={recaptchaRef}
        size="invisible"
        sitekey="Your client site key"
      />
    </form>
  )

}

ReactDOM.render(
  <ReCAPTCHAForm />,
  document.body
);

Advanced usage

Global properties used by reCaptcha

useRecaptchaNet: If google.com is blocked, you can set useRecaptchaNet to true so that the component uses recaptcha.net instead.

Example global properties:

window.recaptchaOptions = {
  useRecaptchaNet: true,
};

CSP Nonce support

window.recaptchaOptions = {
  nonce: document.querySelector('meta[name=\'csp-nonce\']').getAttribute('content'),
};

ReCaptcha loading google recaptcha script manually

You can also use the barebone components doing the following. Using that component will oblige you to manage the grecaptcha dep and load the script by yourself.

import { ReCAPTCHA } from "react-google-recaptcha";

const grecaptchaObject = window.grecaptcha // You must provide access to the google grecaptcha object.

render(
  <ReCAPTCHA
    ref={(r) => this.recaptcha = r}
    sitekey="Your client site key"
    grecaptcha={grecaptchaObject}
  />,
  document.body
);

Hiding the Recaptcha

According to the google docs you are allowed to hide the badge as long as you include the reCAPTCHA branding visibly in the user flow. Please include the following text:

This site is protected by reCAPTCHA and the Google
    <a href="https://policies.google.com/privacy">Privacy Policy</a> and
    <a href="https://policies.google.com/terms">Terms of Service</a> apply.

If you wish to hide the badge you must add:

.grecaptcha-badge { visibility: hidden; }

to your css.

Migrate to 2.0

  • options.removeOnUnmount: REMOVED This was only useful for the lang changes. Lang is now changed through the hl prop.
  • options.lang: REMOVED Instead pass it as the hl prop on the component.

Notes on Requirements

At least React@16.4.1 is required due to forwardRef usage in the dependency react-async-script.

Notes

Pre 1.0.0 and React < 16.4.1 support details in 0.14.0.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

React Google Login Example

Integrate google login in react apps; This example tutorial will show you step by step how to implement google login in react apps using javascript SDK.

If you want to integrate google login authentication in your react app. So you will not need any react plugin for this. In this tutorial, you will learn how to add a google login button in react app without any react plugin.

Before you can integrate Google Sign-In into your react app, you must create a client ID, which you need to call the sign-in API.

To create a Google API Console project and client ID, go to the APIs & Services dashboard and then follow the following steps:

Step 1: Visit Google Developer Console. And create a new project as following in below picture:

Step 2: you will see the screen looks like, show here you can set your project name as you want.

Step 3: Now you have successfully created a new project. After that, you need to select the created projects on the top menu. Then click on OAuth consent screen and select the given option according to your requirement:

Step 4: when you will be done above. After that automatically appear below given screen. In this screen, you need to fill your website URL, privacy policy URL, etc.

Step 5: you need to click on left side menu credentials and appear below screen. In this screen, you need to select OAuth client ID.

Step 6: After that, the below form will be apper. Here From different Application type options, you have to select Web application. Once you have select Web application option, then one form will appear on web page. Here you have to define Name and you have also define Authorized redirect URIs field and lastly click on Create button.

Step 7: the pop looks like below in picture automatically appear. Once you have click on the create button, then you can get your Client ID and your client secret key. You have to copy both key for future use for implement Login using Google account using PHP.

Please note that, google client id and secret.

How to Add Google Login to your React Apps

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

  • React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
  • React.js and React Native have similar syntax and workflows, but their implementation is quite different.
  • React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
  • React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

  • United States- $120,000
  • Canada - $110,000
  • United Kingdom - $71,820
  • The Netherlands $49,095
  • Spain - $35,423.00
  • France - $44,284
  • Ukraine - $28,990
  • India - $9,843
  • Sweden - $55,173
  • Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

  • Conduct thorough candidate research, including portfolios and areas of expertise.
  • Before you sit down with your interviewing panel, do some homework.
  • Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.
