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 🙏

使用 Codegen

本库已经适配了 Codegen ,在使用前需要主动执行生成三方库桥接代码,详细请参考 Codegen 使用文档

Link

目前鸿蒙暂不支持 AutoLink,所以 Link 步骤需要手动配置。

首先需要使用 DevEco Studio 打开项目里的鸿蒙工程 harmony

在工程根目录的 oh-package.json 添加 overrides 字段

{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "./react_native_openharmony"
  }
}

引入原生端代码

目前有两种方法:

  1. 通过 har 包引入(在 IDE 完善相关功能后该方法会被遗弃,目前首选此方法);
  2. 直接链接源码。

方法一:通过 har 包引入(推荐)

[!TIP] har 包位于三方库安装路径的 harmony 文件夹下。

打开 entry/oh-package.json5,添加以下依赖

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-oh-tpl/react-native-performance": "file:../../node_modules/@react-native-oh-tpl/react-native-performance/harmony/react_native_performance.har"
  }

点击右上角的 sync 按钮

或者在终端执行:

cd entry
ohpm install

方法二:直接链接源码

[!TIP] 如需使用直接链接源码,请参考直接链接源码说明

在 ArkTs 侧引入 RNPerformancePackage

打开 entry/src/main/ets/RNPackagesFactory.ts,添加:

...
+ import {RNPerformancePackage} from 'react-native-performance/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new RNPerformancePackage(ctx)
  ];
}

运行

点击右上角的 sync 按钮

或者在终端执行:

cd entry
ohpm install

然后编译、运行即可。

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。

[!tip] "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。

| Name | Description | Type | Required | Platform | HarmonyOS Support | | ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------- | -------- | ----------------| ------------------ | | (property) timeOrigin | 返回Performance用作性能相关时间戳基线的高分辨率时间戳 | number | yes | IOS/Android | yes | | (method) now | 返回一个高分辨率时间戳(以毫秒为单位) | number | yes | IOS/Android | yes | | (method) mark | 根据给出 markName 值,在性能输入缓冲区中创建一个timestamp(时间戳) | Object | yes | IOS/Android | yes | | (method) measure | 性能记录缓存中使用 measure()创建一个新的测量记录如果仅指定了测量名称,则开始时间戳设置为零,结束时间戳(用于计算持续时间)是Performance.now()返回的值。可以使用字符串将PerformanceMark对象标识为开始标记和结束标记。要只提供一个endMark,您需要提供一个空的测量选项对象:performance.Measure(“myMeasure”,{},“myEndMarker”) | Object | yes | IOS/Android | yes | | (method) getEntries | 对于给定的 filter,此方法返回 PerformanceEntry 对象数组,如果不带任何参数,返回全部 entries | Array | yes | IOS/Android | yes | | (method) getEntriesByName | 返回一个给定名称和 name 和 type 属性的PerformanceEntry对象数组 | Array | yes | IOS/Android | yes | | (method) getEntriesByType | 返回一个给定type 属性的PerformanceEntry对象数组 | Array | yes | IOS/Android | yes | | (method) clearMarks | 从缓存中移除声明的标记。如果调用这个方法时没有传递参数,则所有带有entry type这类标记的performance entries 将从 performance entry 缓存区中被移除。 | void | yes | IOS/Android | yes | | (method) clearMeasures | 从缓存区中移除声明的测量记录。如果这个方法被调用时没有传入参数,则所有 entry type 标记值为"measure" 的性能实体将被从性能入口缓存区中移除。 | void | yes | IOS/Android | yes | | (method)observe | observe() 方法用于观察传入的参数中指定的性能条目类型的集合。当记录一个指定类型的性能条目时,性能监测对象的回调函数将会被调用。 | void | yes | IOS/Android | yes
