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 🙏

样例文档

  • 待开发

使用

最少配置参数为:

render() {
    const lists = Array(60).fill(1).map((item, index) => <li key={index}>{index}</li>);//创建一个1-60的列表

    return (
        <div>
            <ul>{lists}</ul>
            <Backtop />     //调用Backtop
        </div>
    )
}

自定义"返回顶部"按钮的样式以及滚动高度

render() {
    const lists = Array(60).fill(1).map((item, index) => <li key={index}>{index}</li>);

    return (
        <div className="container">
            <ul>{lists}</ul>
            <Backtop customClass="custom-back-top" showHeight={300}>  //自定义样式
                <div className="custom-back-top-icon">UP</div>
            </Backtop>
        </div>
    )
}

只有页面局部可以滚动时的用法:

render() {
    const lists = Array(60).fill(1).map((item, index) => <li key={index}>{index}</li>);

    return (
        <div className="container">
            <h3>Lists</h3>
            <ul ref="target">{lists}</ul>      //标记滚动的dom(记得样式中设置body不可以滚动只有ul部分可以滚动)
            <Backtop target={() => this.refs.target} /> //通过target方法把滚动的dom传入
        </div>
    )
}

配置参数

| Prop | Type | Default | Description | | ---- |:----:|:-------:| :----------:| | showHeight | number | 170 | 当滚动高度超过此值时显示"返回顶部"按钮 | | className | string | undefined | 自定义样式 | | target | function | undefined | 执行方法返回页面滚动的dom节点,若是整个页面的滚动就不需要传入此参数 |
