Usage

Getting the Captcha Script

The getCaptchaScript function can be used as follows:

import { getCaptchaScript } from '@captchahub/core';

const config = {
    CAPTCHA_PROVIDER: 'recaptcha',
    RECAPTCHA_SITE_KEY: process.env.RECAPTCHA_SITE_KEY, // Your ReCaptcha site key
};

const CaptchaComponent = async () => {
    const CaptchaScript = (await getCaptchaScript(config)) as React.FC;

    return (
        <div>
            <CaptchaScript />
            {/* Additional form elements */}
        </div>
    );
};

Getting the Captcha Form Element

The getCaptchaFormElement function can be used as follows:

import { getCaptchaFormElement } from '@captchahub/core';

const config = {
    CAPTCHA_PROVIDER: 'recaptcha',
    RECAPTCHA_SITE_KEY: process.env.RECAPTCHA_SITE_KEY, // Your ReCaptcha site key
};

const CaptchaFormComponent = async () => {
    const CaptchaFormElement = (await getCaptchaFormElement(config)) as React.FC;

    return (
        <div>
            <CaptchaFormElement />
            {/* Additional form elements */}
        </div>
    );
};

Verifying the Captcha

The verifyCaptcha function can be used as follows:

import { verifyCaptcha } from '@captchahub/core';

const config = {
    CAPTCHA_PROVIDER: 'recaptcha',
    RECAPTCHA_SECRET_KEY: process.env.RECAPTCHA_SECRET_KEY, // Your ReCaptcha secret key
};

const formFieldValues = {
    // Your form field values that need to be verified
};

const isValid = await verifyCaptcha(formFieldValues, config);
if (isValid) {
    console.log('Captcha verified successfully!');
} else {
    console.error('Captcha verification failed.');
}

Configuration

Configuration for the ReCaptcha provider can be defined in a configuration object passed to the factory when creating the captcha instance. The configuration object must include the CAPTCHA_PROVIDER property to specify which captcha provider to use. Additionally, you will need to provide the RECAPTCHA_SITE_KEY and RECAPTCHA_SECRET_KEY for proper functionality.

Extensibility

The @captchahub/recaptcha package is designed to be extensible. You can create new captcha providers by implementing the CaptchaInterface. This allows you to add support for additional captcha services in the future.

Rationale

The @captchahub/recaptcha package is designed to provide integration with the Google ReCaptcha service for managing captcha workflows in TypeScript applications. By using the core package, developers can easily integrate ReCaptcha capabilities into their web applications.
