react-native-recaptcha-enterprise

Google Enterprise reCaptcha. Implemented through native platforms. Support iOS and Android

---

Installation

• Requires React Native version 0.60.0, or later.
• Supports iOS 13.0, or later,
• Supports android 23 level, or later.

via NPM

npm install react-native-recaptcha-enterprise

via Yarn

yarn add react-native-recaptcha-enterprise

📱iOS (Extra steps)

• Since ios project is written in Swift, you need to have Swift enabled in your iOS project. If you already have any .swift files, you are good to go. Otherwise, create a new empty Swift source file in Xcode, and allow it to create the neccessary bridging header when prompted.
• pod install

for react-native 0.71.xx and higher

Since 0.71 version of RN in pod-configuration is enabled to mix-up static and dynamic frameworks. You can configure static frameworks globally (as current package requires that) via

use_frameworks! :linkage => :static

or override this field for specific pod like this

pod 'react-native-recaptcha-enterprise', :path => "../node_modules/react-native-permissions", :linkage => :static, :modular_headers => true

You can see an example in Example/ios/Podfile

Example

In example folder there is simple workflow how to:

• Initialize reCaptcha client
• Execute actions
• Check availability
• Handle errors

How it looks like you can see here

Not init session	Executed action (login)

Error unavailable (no Google Play Service)	Error from native part (with code and description)

Methods

Important: All methods are promise based and can throw exceptions. List of errors is provided in Error handling section

Initialize ReCaptcha

It is better to call it somewhere in the startup and use as Singleton instance further

import { initializeRecaptcha } from 'react-native-recaptcha-enterprise';

await initializeRecaptcha('YOUR_SITE_KEY');

Execute

This method works only on initialized reCaptcha client see initialization upper.

There is only one constant action-name - LOGIN. Another as VIEWED_CART, SIGNIN could be added by request. You can pass any custom action name here, but it will be prefixed with string constant custom_

import { executeAction } from 'react-native-recaptcha-enterprise';

const executeResult = await executeAction('YOUR_ACTION_NAME');
console.info('Token verify: ', executeResult);

Check availability

In some cases this library doesn't work on native level. The reason why it happens - missing Google Play Service (gms package). It could be a real case of you end users as some smartphones doesn't have Google environment at all as Xiaomi, Huawei etc. So it is recomended to check it before, or you can handle error in initialization handler by:

errorCode === RecaptchaErrorCodes.NotAvailable

As availability check is called on native part during initialization too.

Implementation of direct method call:

const checkAvailability = useCallback(async () => {
  try {
    setInProgress(true);
    const canUseResult = await canUseRecaptcha();

    if (canUseResult.result) {
      setCanUse(true);
      return;
    }

    setCanUse(false);
    Alert.alert(
      'ReCaptcha Availability',
      'Google ReCaptcha can not be used. Reason: ' + canUseResult.reason
    );
  } catch (e: any) {
    setError(`${e?.message}[code: ${e?.code}]`);
  } finally {
    setInProgress(false);
  }
}, []);

Error handling:

List of supported events:

export enum RecaptchaErrorCodes {
  'NotInitializedClient' = 'NotInitializedClient',
  'NotAvailable' = 'NotAvailable',
  /* Android: UNKNOWN_ERROR, ios: RecaptchaErrorCodeUnknown */
  'RecaptchaErrorCodeUnknown' = 0,
  /* Android: NETWORK_ERROR, ios: RecaptchaErrorNetworkError */
  'RecaptchaErrorNetworkError' = 1,
  /* Android: INVALID_SITEKEY, ios: RecaptchaErrorInvalidSiteKey */
  'RecaptchaErrorInvalidSiteKey' = 2,
  /* Android: INVALID_KEYTYPE, ios: RecaptchaErrorInvalidKeyType */
  'RecaptchaErrorInvalidKeyType' = 3,
  /* Android: INVALID_PACKAGE_NAME, ios: RecaptchaErrorInvalidPackageName */
  'RecaptchaErrorInvalidPackageName' = 4,
  /* Android: INVALID_ACTION, ios: RecaptchaErrorInvalidAction */
  'RecaptchaErrorInvalidAction' = 5,
  /* Android: INTERNAL_ERROR, ios: RecaptchaErrorCodeInternalError */
  'RecaptchaErrorCodeInternalError' = 100,
}

All throwable exception from native part has common object structure:

export type RecaptchaErrorType = {
  code: RecaptchaErrorCodes;
  message: string;
  rawData: any;
};

Where:

• code - is error code constant (in human-readable format)
• message - description of error, to define what happened.
• rawData - whole error object thrown from native part.

You can handle it with Promise.catch().then() approach - classical Promise resolving or use modern one - async/await in combination with try/catch statement.

Short example:

try {
  setInProgress(true);
  const executeResult = await executeAction(actionName);
  setToken(executeResult);
} catch (e: any) {
  // Where: e - is RecaptchaErrorType
  console.log(`${e?.message}[code: ${e?.code}]`);
} finally {
  setInProgress(false);
}
