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 🙏

安装与使用

请到三方库的 Releases 发布地址查看配套的版本信息:@tuya-oh/art Releases 。对于未发布到npm的旧版本,请参考安装指南安装tgz包。

进入到工程目录并输入以下命令:

npm

npm install @tuya-oh/art

yarn

yarn add @tuya-oh/art

下面的代码展示了这个库的基本使用场景:

[!WARNING] 使用时 import 的库名不变。

// @flow
import React from 'react';
import {StyleSheet, Dimensions} from 'react-native';
import {
  Surface,
  Shape,
  Group
} from '@react-native-community/art';

const HEART_SHAPE = 
'M 10,30 A 20,20 0,0,1 50,30 A 20,20 0,0,1 90,30 Q 90,60 50,90 Q 10,60 10,30 z';

const App = () => {
  return (
    const surfaceDimensions = Dimensions.get('window').width;

    return (
      <Surface
        width={surfaceDimensions}
        height={surfaceDimensions / 2}
        style={styles.surface}>
        <Group
          x={surfaceDimensions / 2 - 50}
          y={surfaceDimensions / 4 - 50}
          visible={true}>
          <Shape
            d={HEART_SHAPE}
            strokeWidth={5}
            stroke={'#00ff00'}
            visible={true}
          />
        </Group>
      </Surface>
    );
  );
};

export default App;

const styles = StyleSheet.create({
  surface: {
    backgroundColor: 'black',
  }
});

本库 HarmonyOS 侧实现依赖@react-native-oh-tpl/react-native-svg 的原生端代码,如已在 HarmonyOS 工程中引入过该库,则无需再次引入,可跳过本章节步骤,直接使用。

如未引入请参照 @react-native-oh-tpl/react-native-svg 进行引入

约束与限制

兼容性

要使用此库,需要使用正确的 React-Native 和 RNOH 版本。另外,还需要使用配套的 DevEco Studio 和 手机 ROM。

此库依赖于react-native-svg库,详情见请到三方库相应的 Releases 发布地址查看 Release 配套的版本信息:@react-native-oh-tpl/react-native-svg****
