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 🙏

Text

Text 用于显示文本,在 web 端即 <span> 标签。

注意: Text 标签不支持嵌套,嵌套使用可能会导致意想不到的结果。


API

参数 | 说明 | 类型 | 默认值 -----|-----|-----|----- style | 样式 | object|{display:'block',fontSize:32} onPress | 点击事件 | function numberOfLines| 显示的行数|number fixedFont|字体大小是否固定,默认 false ,即跟随屏幕宽度缩放|false

关于 numberOfLines 控制多行文本

// 超出 2 行隐藏且显示省略号
<View style={{backgroundColor: '#cccccc'}}>
  <Text numberOfLines={2}  style={{
    fontSize: 28,
    textOverflow: 'ellipsis',
    overflow: 'hidden',
    color: '#333333',
    lineHeight: 48,
    height: 48*2
    }}>
    Different from a "web app", "HTML5 app", or "hybrid app", you can use Weex to build a real mobile app.
  </Text>
</View>

关于 fixedFont

由于 rem 单位是根据屏幕宽度计算而自动缩放的:

750rem = 1 deviceWidth

因此,<Text style={{fontSize: 28}}>123</Text> 实际算出来的字号也是随着屏幕宽度缩放的。

某些场景下,为了避免屏幕超大、超小导致文字过大或过小,你可以选择 fixedFont 来固化字号的显示。

例如:<Text style={{fontSize: 28}} fixedFont={true}>123</Text> 这意味字体实际字号将被解析为:

web: 14px;
native iOS: 14 dp;
native android: 14 pt;

native 端的 dp pt 确保了字号在任何不同 dpi 的手机屏幕上显示不会发生改变。
