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 🙏

模板版本:v0.2.2

安装与使用

进入到工程目录并输入以下命令:

npm

npm install @ohmi/masked-view

yarn

yarn add @ohmi/masked-view

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。

import { StyleSheet, Text, View } from 'react-native';
import MaskedView from '@react-native-masked-view/masked-view';

const MaskedDemo = () => {
    return (
        <MaskedView
            style={styles.maskedView}
            maskElement={
                <View style={styles.maskElementView}>
                    <Text style={styles.maskElementText}>Basic Mask</Text>
                </View>
            }
        > 
        <View style={{ width:'100%', height: 40, backgroundColor: '#fe4b83' }} />
        <View style={{ width:'100%', height: 40, backgroundColor: '#F5DD90' }} />
        </MaskedView>
    )
}

const styles = StyleSheet.create({
    maskedView: {
        width:'100%',
        height:'40%'
    },
    maskElementView: {
        backgroundColor: 'transparent',
        alignItems: 'center',
        width:'100%',
        height:'100%',
        justifyContent: 'center',
    },
    maskElementText: {
        color: Colors.black,
        width:'100%',
        height:60,
        fontSize: 50,
        fontWeight: 'bold',
    },
    textView: {
        fontSize: 20,
        alignItems: 'center',
        width:'100%',
        height:40,
        flexDirection: 'row',
        justifyContent: 'center',
    },
    text: {
        color: Colors.darkChestnut,
        fontSize: 8,
        width:'100%',
        height:40,
        fontVariant: ['small-caps'],
        fontWeight: 'bold',
    },
});

export default MaskedDemo

Link

目前 HarmonyOS 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 HarmonyOS 工程 harmony

1.在工程根目录的 oh-package.json5 添加 overrides 字段

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

2.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",

    "@ohmi/masked-view": "file:../../node_modules/@ohmi/masked-view/harmony/masked_view.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 MaskedPackage

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 "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${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_MODULES}/@ohmi/masked-view/src/main/cpp" ./masked-view)
# 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_masked_view)
# RNOH_END: manual_package_linking_2

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

#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
#include "SamplePackage.h"
+ #include "MaskedPackage.h"

using namespace rnoh;

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

4.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。

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-library/masked-view Releases

属性

[!TIP] "Platform"列表示该属性在原三方库上支持的平台。

[!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 | | ---------------------- | ------------ | ------------------ | -------- | -------- | ----------------- | | maskElement | 遮罩元素 | element | yes | All | yes | | androidRenderingMode | 安卓渲染模式 | software, hardware | no | android | no |
