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 🙏

简介

react-native-bootsplash 库用于 React Native。 react-native-bootsplash 是一个启动屏(Splash Screen)库,可在应用启动时展示启动屏,并提供隐藏启动屏、查询可见状态及自定义隐藏动画等能力。

下载安装

进入到工程目录并输入以下命令:

npm

npm install @react-native-ohos/react-native-bootsplash

yarn

yarn add @react-native-ohos/react-native-bootsplash

生成配置文件

为了加快设置速度,我们提供了一个CLI来自动生成配置、创建Android Drawable XML文件、iOS Storyboard文件和HarmonyOS Resources文件

$ npx react-native generate-bootsplash --help
# --- or ---
$ yarn react-native generate-bootsplash --help

该命令可以使用多个参数:

Usage: react-native generate-bootsplash [options] <logo>

Generate a launch screen using a logo file path (PNG or SVG)

Options:
  --project-type <string>     Project type ("detect", "bare" or "expo") (default: "detect")
  --platforms <list>          Platforms to generate for, separated by a comma (default: "android,ios,web,harmony")
  --background <string>       Background color (in hexadecimal format) (default: "#fff")
  --logo-width <number>       Logo width at @1x (in dp - we recommend approximately ~100) (default: 100)
  --assets-output <string>    Assets output directory path (default: "assets/bootsplash")
  --flavor <string>           Android flavor build variant (where your resource directory is) (default: "main")
  --html <string>             HTML template file path (your web app entry point) (default: "public/index.html")
  --license-key <string>      License key to enable brand and dark mode assets generation
  --brand <string>            Brand file path (PNG or SVG)
  --brand-width <number>      Brand width at @1x (in dp - we recommend approximately ~80) (default: 80)
  --dark-background <string>  [dark mode] Background color (in hexadecimal format)
  --dark-logo <string>        [dark mode] Logo file path (PNG or SVG)
  --dark-brand <string>       [dark mode] Brand file path (PNG or SVG)
  -h, --help                  display help for command

命令用法示例:

# Without license key
npx react-native generate-bootsplash svgs/light-logo.svg

命令执行后将创建以下文件:

# Without license key

编辑您的启动Ability文件, 它通常是配置在entry模块module.json5中abilities属性中配置的第一个ability:

+ import { window } from '@kit.ArkUI';

+ import { RNBootSplashScreen } from '@react-native-ohos/react-native-bootsplash/src/main/ets/RNBootSplashScreen';

export default class EntryAbility extends RNAbility {
+  onWindowStageCreate(windowStage: window.WindowStage) {
+     RNBootSplashScreen.init(this.context, windowStage).then(() => {
+       super.onWindowStageCreate(windowStage);
+     })
+  }

  ...
}

Link

| | 是否支持autolink | RN框架版本 | |--------------------------------------|-----------------|------------| | ~6.4.0 | Yes | 0.82 |

使用AutoLink的工程需要根据该文档配置,Autolink框架指导文档:https://gitcode.com/CPF-RN/ohos_react_native/blob/master/docs/zh-cn/Autolinking.md

如您使用的版本支持 Autolink,并且工程已接入 Autolink,可跳过ManualLink配置。

首先需要使用 DevEco Studio 打开项目里的 HarmonyOS 工程 harmony。

1. Overrides RN SDK

为了让工程依赖同一个版本的 RN SDK,需要在工程根目录的 oh-package.json5 添加 overrides 字段,指向工程需要使用的 RN SDK 版本。替换的版本既可以是一个具体的版本号,也可以是一个模糊版本,还可以是本地存在的 HAR 包或源码目录。

关于该字段的作用请阅读官方说明

{
  "overrides": {
    "@rnoh/react-native-openharmony": "^0.82.7" // ohpm 在线版本
    // "@rnoh/react-native-openharmony" : "./react_native_openharmony.har" // 指向本地 har 包的路径
    // "@rnoh/react-native-openharmony" : "./react_native_openharmony" // 指向源码路径
  }
}

2. 引入原生端代码

目前有两种方法:

  • 通过 har 包引入;
  • 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-ohos/react-native-bootsplash": "file:../../node_modules/@react-native-ohos/react-native-bootsplash/harmony/boot_splash.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

3. 配置 CMakeLists 和引入 BootSplashPackage

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

project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_SKIP_BUILD_RPATH TRUE)
set(RNOH_APP_DIR "${CMAKE_CURRENT_SOURCE_DIR}")
set(NODE_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../node_modules")
set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
+set(OH_MODULE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../react-native-harmony/harmony/cpp")
set(LOG_VERBOSITY_LEVEL 1)
set(CMAKE_ASM_FLAGS "-Wno-error=unused-command-line-argument -Qunused-arguments")
set(CMAKE_CXX_FLAGS "-fstack-protector-strong -Wl,-z,relro,-z,now,-z,noexecstack -s -fPIE -pie")
set(WITH_HITRACE_SYSTRACE 1) # for other CMakeLists.txt files to use
add_compile_definitions(WITH_HITRACE_SYSTRACE)

add_subdirectory("${RNOH_CPP_DIR}" ./rn)

# RNOH_BEGIN: manual_package_linking_1
add_subdirectory("../../../../sample_package/src/main/cpp" ./sample-package)

+ add_subdirectory("${OH_MODULE_DIR}/@react-native-ohos/react-native-bootsplash/src/main/cpp" ./bootsplash)

# RNOH_END: manual_package_linking_1

file(GLOB GENERATED_CPP_FILES "./generated/*.cpp")

add_library(rnoh_app SHARED
    ${GENERATED_CPP_FILES}
    "./PackageProvider.cpp"
    "${RNOH_CPP_DIR}/RNOHAppNapiBridge.cpp"
)
target_link_libraries(rnoh_app PUBLIC rnoh)

# RNOH_BEGIN: manual_package_linking_2
target_link_libraries(rnoh_app PUBLIC rnoh_sample_package)
+ target_link_libraries(rnoh_app PUBLIC rnoh_boot_splash)
# RNOH_END: manual_package_linking_2

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

#include "RNOH/PackageProvider.h"
#include "SamplePackage.h"
+ #include "BootSplashPackage.h"

using namespace rnoh;

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

4. 在 ArkTs 侧引入 RNBootSplashPackage

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

  ...
+ import { RNBootSplashPackage } from '@react-native-ohos/react-native-bootsplash/ts';

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

无

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。

在以下版本验证通过:

  1. RNOH: 0.82.7; SDK: HarmonyOS 6.0.1 Release; IDE: DevEco Studio 6.0.1 Release; ROM:6.0.0.328 SP26;

使用示例

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。

[!TIP] 示例中logo参数使用了本地图片资源,可以到react-native-boot-splash demo获取该图片

import { useState , useEffect} from "react";
import { Animated, View, Text, Dimensions, Platform, StatusBar, StyleSheet } from "react-native";
import BootSplash from "react-native-bootsplash";

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    alignItems: "center",
    backgroundColor: "#F5FCFF",
  },
  text: {
    fontSize: 30,
    fontWeight: "700",
    margin: 20,
    lineHeight: 30,
    color: "#333",
    textAlign: "center",
  },
});

type Props = {
  onAnimationEnd: () => void;
};

export const AnimatedBootSplash = ({ onAnimationEnd }: Props) => {
  const [opacity] = useState(() => new Animated.Value(1));
  const [translateY] = useState(() => new Animated.Value(0));

  const { container, logo /*, brand */ } = BootSplash.useHideAnimation({
    manifest: require("../source/bootsplash_manifest.json"),
    logo: require("../source/bootsplash_logo.png"),

    animate: () => {
      const { height } = Dimensions.get("window");
      Animated.stagger(250, [
        Animated.spring(translateY, {
          useNativeDriver: true,
          toValue: -50,
        }),
        Animated.spring(translateY, {
          useNativeDriver: true,
          toValue: height,
        }),
      ]).start();
      Animated.timing(opacity, {
        useNativeDriver: true,
        toValue: 0,
        duration: 150,
        delay: 350,
      }).start(() => {
        onAnimationEnd();
      });
    },
  });

  return (
    <Animated.View {...container} style={[container.style, { opacity }]}>
      <Animated.Image
        {...logo}
        style={[logo.style, { transform: [{ translateY }] }]}
      />
    </Animated.View>
  );
};

const App = () => {
  const [visible, setVisible] = useState(true);

  useEffect(() => {
    StatusBar.setBarStyle("dark-content");
  }, []);

  return (
    <>
      <View style={styles.container}>
        <Text style={styles.text}>Hello World</Text>
        {visible && (
          <AnimatedBootSplash
            onAnimationEnd={async () => {
              await BootSplash.isVisible();
              setVisible(false);
            }}
          />
        )}
      </View>
    </>
  );
};

export default App;
// bootsplash_manifest.json
{
  "background": "#F5FCFF",
  "logo": {
    "width": 300,
    "height": 89
  }
}

遗留问题

  • [ ] HarmonyOS的window窗口上不支持设置动画属性,hide接口fade参数设置true没有效果 问题: issue#13
  • [ ] HarmonyOS上不支持navigationBarTranslucent属性,useHideAnimation接口navigationBarTranslucent参数设置true没有效果 问题: issue#6
  • [ ] HarmonyOS上不支持statusBarTranslucent属性,useHideAnimation接口statusBarTranslucent参数设置true没有效果 问题: issue#6
  • [ ] HarmonyOS 为原生子窗口 + RN 窗口双窗口启动屏方案,hide 切换可能闪烁;generate-bootsplash 会生成双层资源,HarmonyOS 上不建议两者复用同一套启动图/背景,否则易出现重复衔接并闪烁 问题: issue#21
  • [ ] HarmonyOS getConstants() 的 statusBarHeight/navigationBarHeight 为 px 非 dp,logoSizeRatio 固定为 1;与 Android API 语义不一致,但鸿蒙 useHideAnimation 未使用这些字段(仅 darkModeEnabled 生效),不影响现有功能 问题: issue#37

其他

  • 执行generate-bootsplash命令行时,由于 --brand, --brand-width 和 --dark-* 选项需要购买license才能使用,涉及功能未开源,HarmonyOS平台不支持使用
