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 🙏

react-native-tabs

项目介绍

tab标签的头部组件.点击触发跳转事件并将触发的tab移动到app中间位置.

内部使用渲染优化,没有变化的时候不再重复刷新渲染结果.

安装教程

  1. 安装tabs组件.npm i --save react-native-tabs-top
  2. 引用组件.
  3. 添加需要的props

使用说明

申明tab组件用到的key和显示用的名称

this.setState({tablist:[{id:1,name:"tab1"}]})

在合适的地方写好组件和他们的触发事件

<TabBar ref={e => this.tabs = e}
    index={this.state.index}
    data={this.state.tablist}
    onChange={index => {}} />

tab切换内容

简单的切换可以使用View的显示隐藏来切换,这里的显示内容可以做一个缓存,无需每次都创建.

    {index===0 && <View></View>}
    {index===1 && <View></View>}

配合组件来切换,之类使用的是react-native-scrollable-tab-view组件.

   <TabView page={this.state.activeTab}
        initialPage={0} 
        onChangeTab={(i) => this.ChangeTab(i)}>
        {this.state.tabs.map((item, index) => <View />)}
    </TabView>
