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 🙏

Readme

react-native-svga

SVGA 是一种同时兼容 iOS / Android / Flutter / Web 多个平台的动画格式。

这是根据原生svga封装的RN插件

特点

  1. 新增预加载
  2. 可以把svga资源放js里,而不必放原生项目中

安装

yarn add react-native-svga

1. 运行

  • ios npx pod-install
  • android npx jetify

2. Android 配置

  • AndroidManifest.xml 标签里配置 tools:replace="android:allowBackup" 否则会报错
  * What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
> Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:11:7-34
  	is also present at [com.github.yyued:SVGAPlayer-Android:2.5.15] AndroidManifest.xml:12:9-35 value=(true).
  	Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:7:5-12:19 to override.

3. iOS 配置

4. JS项目配置(如果不把svga文件放js中可以跳过)

metro.config.js , 否则会报引用不到资源

module.exports = (async () => {
  const defaultAssetExts = require("metro-config/src/defaults/defaults").assetExts;
  return {
    resolver: {
      assetExts: [...defaultAssetExts, 'svga'],
    },
    transformer: {
      getTransformOptions: async () => ({
        transform: {
          experimentalImportSupport: false,
          inlineRequires: false,
        },
      }),
    },
  };
})();

使用

大概就是这样吧, svgaTag获取到实例后可以作一些暂停,清空,恢复等操作,具体看example

import { ISvgaProps, SVGAView } from 'react-native-svga'

// 本地
source: SVGAModule.getAssets(require('./posche.svga'))

// 网络
source: 'https://github.com/yyued/SVGA-Samples/blob/master/heartbeat.svga?raw=true'

// eg
const { width, height } = Dimensions.get('window')
const kScreenW = width
const kScreenH = height

let svgaTag: SVGAView

<SVGAView
                  ref={ref => (svgaTag = ref)}
                  source: 'https://github.com/yyued/SVGA-Samples/blob/master/heartbeat.svga?raw=true'
                  loop={1}
                  style={{ width: kScreenW, height: kScreenH }}
                  onFinished={() => {
                        console.log("finish")
                  }}
                />


// 暂停
svgaTag.pauseAnimation()

// 恢复
svgaTag.startAnimation()
