hCaptcha Loader
This is a JavaScript library to easily configure the loading of the hCaptcha JS client SDK with built-in error handling. It also includes a retry mechanism that will attempt to load the hCaptcha script several times in the event if fails to load due to a network or unforeseen issue.
hCaptcha is a drop-replacement for reCAPTCHA that protects user privacy.
Sign up at hCaptcha to get your sitekey today. You need a sitekey to use this library.
Installation
npm install @hcaptcha/loaderImplementation
import { hCaptchaLoader } from '@hcaptcha/loader';
await hCaptchaLoader();
hcaptcha.render({
sitekey: '<your_sitekey>'
});
const { response } = await hcaptcha.execute({ async: true });Props

Legacy Support
In order to support older browsers, a separate bundle is generated in which all ES6 code is compiled down to ES5 along with an optional polyfill bundle.
polyfills.js: Provides polyfills for features not supported in older browsers.index.es5.js: @hcaptcha/loader package compiled for ES5 environments.
Import Bundle(s)
Both bundles generated use IIFE format rather than a more modern import syntax such as require or esm.
// Optional polyfill import
import '@hCaptcha/loader/dist/polyfills.js';
// ES5 version of hCaptcha Loader
import '@hCaptcha/loader/dist/index.es5.js';
hCaptchaLoader().then(function(hcaptcha) {
var element = document.createElement('div');
// hCaptcha API is ready
hcaptcha.render(element, {
sitekey: 'YOUR_SITE_KEY',
// Additional options here
});
});
TypeScript
To handle typescript with ES5 version, use the following statement.
declare global {
interface Window {
hCaptchaLoader: any;
}
}CDN
The hCaptcha Loader targeted for older browsers can also be imported via CDN by using UNPKG, see example below.
