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 🙏

@bingtang-rn/react-native-draw-overlay

v1.0.1

Published

适配鸿蒙版本,提供react_native_draw_overlay组件。

Readme

@bingtang-rn/react-native-draw-overlay for HarmonyOS

本项目基于 @vokhuyet/react-native-draw-overlay 开发,为 React Native 鸿蒙(OpenHarmony)适配版本。如果在使用过程中有任何问题,可以在GitCode提Issue,会及时跟进。issue地址:issues

版本对应关系

| 鸿蒙适配包版本 | 原始库版本 | 支持 RN 版本 | Autolink | 编译 API 版本 | | ------------ | ---------- | ------------ | -------- | ------------- | | 见发布记录 | 1.0.1 | 0.72+ | 是 | API17+ |

安装

npm install @bingtang-rn/react-native-draw-overlay

使用

import { requestOverlayPermission, isOverlayPermissionGranted } from '@vokhuyet/react-native-draw-overlay';

// 检查悬浮窗权限是否已授予
const granted = await isOverlayPermissionGranted();
console.log('Overlay permission granted:', granted);

// 请求悬浮窗权限
const result = await requestOverlayPermission();
console.log('Permission request result:', result);

import 时使用原库名 '@vokhuyet/react-native-draw-overlay',而非鸿蒙包名。

平台差异

  • Android 通过跳转系统设置页让用户手动开启悬浮窗权限;HarmonyOS 通过 requestPermissionsFromUser 弹窗申请,交互更简洁。

权限要求

  • 需在 module.json5requestPermissions 中声明 ohos.permission.SYSTEM_FLOAT_WINDOW(user_grant 权限,运行时自动申请)。

Link

| 版本 | 是否支持 Autolink | |------|------------------| | 当前版本 | 是 |

如使用版本支持 Autolink 且工程已接入,可跳过手动配置。

说明:本模块需要同时在 C++ 侧和 ETS 侧注册 Package。

1. Overrides RN SDK

在工程根目录 oh-package.json5 添加:

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

2. 引入原生端依赖

打开 entry/oh-package.json5,添加:

"dependencies": {
  "@bingtang-rn/react-native-draw-overlay": "file:../../node_modules/@bingtang-rn/react-native-draw-overlay/harmony/draw_overlay.har"
}

执行 ohpm install

3. 配置 CMakeLists

打开 entry/src/main/cpp/CMakeLists.txt,添加:

set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")

add_subdirectory("${OH_MODULES}/@bingtang-rn/react-native-draw-overlay/src/main/cpp" ./draw_overlay)

target_link_libraries(rnoh_app PUBLIC draw_overlay)

4. 注册 Package(C++ 侧)

打开 entry/src/main/cpp/PackageProvider.cpp,添加:

#include "DrawOverlayPackage.h"

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
        std::make_shared<DrawOverlayPackage>(ctx),
    };
}

5. 注册 Package(ETS 侧)

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

import { DrawOverlayPackage } from '@bingtang-rn/react-native-draw-overlay/ts';

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

属性 / API

| API | 描述 | 参数 | 返回值 | HarmonyOS 支持 | |-----|------|------|--------|----------------| | requestOverlayPermission | 请求悬浮窗权限 | 无 | Promise<boolean> | ✅ 完全支持 | | isOverlayPermissionGranted | 检查悬浮窗权限是否已授予 | 无 | Promise<boolean> | ✅ 完全支持 |

平台差异

  • requestOverlayPermission:Android 跳转系统设置页 Settings.ACTION_MANAGE_OVERLAY_PERMISSION,HarmonyOS 通过 abilityAccessCtrl.requestPermissionsFromUser 弹窗申请。两者语义一致(请求权限→返回授权结果),但交互方式不同。
  • isOverlayPermissionGranted:Android 使用 Settings.canDrawOverlays() + AppOpsManager.checkOp() 多层降级检测;HarmonyOS 使用 abilityAccessCtrl.checkAccessToken() 直接查询权限状态,无需降级方案。

快速验证(运行 Example)

前置条件

| 依赖 | 版本要求 | |------|----------| | Node.js | >= 18 | | DevEco Studio | 5.0+ / 6.0+ | | HarmonyOS SDK | API 17+ |

运行步骤

1. 克隆仓库

git clone <仓库地址>
cd <仓库目录>

2. 安装依赖并构建

npm install --legacy-peer-deps
npm pack           # 生成 tgz 包(会自动触发 prepare 构建 JS 产物)

3. 进入 example 目录,安装依赖

cd example
npm install --legacy-peer-deps

4. 生成 JS Bundle

npm run dev

产物:harmony/entry/src/main/resources/rawfile/bundle.harmony.js

5. 用 DevEco Studio 打开鸿蒙工程

  • 打开 DevEco Studio
  • 选择 example/harmony 目录
  • 等待 Sync 完成

6. 编译并运行 HAP

在 DevEco Studio 中点击运行按钮,将 HAP 安装到设备/模拟器。

注意:Example 中已预置插件依赖和 Package 注册,无需手动配置 Link。

约束与限制

兼容性

  • RNOH: 0.72+
  • HarmonyOS SDK: API 17+
  • DevEco Studio: 5.0+
