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 🙏

observe-dom-resize

DOM元素监听尺寸变化


该插件通过一定巧妙的策略,使得任意元素可以监听resize 事件, 通过事件驱动回调,相比MutationObserver 或者循环检查 性能更高, 兼容ie9以上所有浏览器


安装方法

    npm install observe-dom-resize

示例

监听dom尺寸变化

    import {
        DOMObserver
        DOMObserverResize,
	    DOMObserveWidth,
        DOMObserveHeight
    } from 'observer-dom-resize';

    const someDom = document.querySelector('.some');
    // 监听dom尺寸变化
    const unObserver1 = DOMObserver('resize', someDom, () => {
        console.log('DOM 尺寸发生变化了')
    })

    // 监听Dom 的Width变化
     const unObserver2 = DOMObserveWidth(someDom, () => {
        console.log('DOM width发生变化了');
    }); // ===  DOMObserver('width', someDom, ()=> {})

    // 监听Dom 的Height变化
    const unObserver3 = DOMObserveWidth(someDom, () => {
        console.log('DOM height发生变化了');
    }); // ===  DOMObserver('height', someDom, ()=> {})

    // 监听Dom 的resize变化
    const unObserver4 = DOMObserveResize(some, () => {
        console.log('DOM 尺寸发生变化了');
    }); // ===  DOMObserver('resize', someDom, ()=> {})

    // 取消监听dom
    unObserver1(); unObserver2(); unObserver3(); unObserver4();

Note: DOMObserver type 只能为 resize, width, height
