JSE Captcha

JSECOIN [THE FUTURE BLOCKCHAIN & ECOSYSTEM FOR ECOMMERCE AND DIGITAL ADVERTISING]

WARNING

We are still working on the interface and know there are still a number of bugs and cross browser issues - please be patient.. in the meantime please use our original captcha UI code from here.

Overview

JSE Captcha is a free to use bot prevention tool. It can be used to protect content and endpoints from automated requests.

Official Release and Developer docs acan be found here: https://developer.jsecoin.com

Setting up the captcha requires two parts, a code snippet on the web page and then a server-side verification check.

Server-side Verification It is essential to check the captcha has been completed using server-side code to protect your endpoints. We do this using the clients IP address (IPV4) and the following URL:

https://api.jsecoin.com/captcha/check/:ipAddress/

PS.. Check out our live Platform.

Technology:

JSE Captcha has been built with Svelte.

Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app.

Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes.

1. Re-use in Svelte Apps

<script>
  import JSEcaptcha from 'JSEcaptcha.svelte';
</script>

<JSEcaptcha theme="flat" size="M" on:success="{() => console.log('On success!')}" on:fail="{() => console.log('On fail!')}" />

2. All other Apps / Sites can use IIFE:

IIFE build:

<script src='/jsecaptcha.iife.min.js'></script>

<div id="captcha"></div>

Add component:

var jseCaptcha = new Jsecaptcha({
    target: document.getElementById('captcha'), //injection point
    props: {
        size: 'S', // ['','S','M','L']
        theme: 'flat', //['','flat']
        //captchaServer: 'https://load.jsecoin.com', //just for JSE devs
    }
});

//success response
jseCaptcha.$on('success', (res) => {
    console.log('Success: ', res.detail);
});

//failed reponse
jseCaptcha.$on('fail', (res) => {
    console.log('Fail: ', res.detail);
});
