Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v1.3.0

Published

A React sliding captcha component for user verification.

Readme

rc-slider-captcha

一个用于实现滑动验证码的 React 组件,用户通过滑动拼图来完成身份验证。

安装

npm install @bonboru93/rc-slider-captcha

示例

import SliderCaptcha from "@bonboru93/rc-slider-captcha";

const App = () => {
  const handleLoad = async () => {
    // 返回背景图和拼图的 URL
    return {
      bgSrc: "https://example.com/bg.jpg",
      puzzleSrc: "https://example.com/puzzle.png",
    };
  };

  const handleCheck = async offset => {
    // 校验偏移量,如果有效则 resolve,无效则 reject
    if (offset === 42) {
      return; // 偏移量正确
    } else {
      throw new Error("偏移量无效");
    }
  };

  return (
    <div>
      <h1>滑动验证码示例</h1>
      <SliderCaptcha onLoad={handleLoad} onCheck={handleCheck} />
    </div>
  );
};

export default App;

图片要求

背景图显示大小为320x160,拼图高度与背景图相同,宽度为60。

请提供等比例图片,源码中有示例图。

属性说明

| 属性 | 类型 | 必填 | 说明 | |------------|------------------------------------------|------|------------------------------------------------------------| | onLoad | () => Promise<{ bgSrc: string; puzzleSrc: string }> | 是 | 加载背景图和拼图图像的 URL。 | | onCheck | (offset: number) => Promise<void> | 是 | 校验滑块偏移量。成功时 resolve,失败时 reject。|

原理

滑动条本质是input[type="range"]。样式基于-webkit-slider-thumb和-moz-range-thumb实现,代码极其简单。

如有兼容性问题,请提issue。
