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 🙏

v2.1.2-1.0.1

Published

A native implementation of base64 in C++ for React Native

Readme

模板版本:v0.2.2

[!TIP] Github 地址

安装与使用

请到三方库的 Releases 发布地址查看配套的版本信息:@react-native-oh-tpl/react-native-quick-base64 Releases,并下载适用版本的 tgz 包。

进入到工程目录并输入以下命令:

[!TIP] # 处替换为 tgz 包的路径

npm

npm install @react-native-oh-tpl/react-native-quick-base64@file:#

yarn

yarn add @react-native-oh-tpl/react-native-quick-base64@file:#

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 { btoa, atob } from 'react-native-quick-base64'

const base64 = btoa('foo')
const decoded = atob(base64)

使用Codegen

本库未带rc.x的版本号是已经适配了 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 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

在工程根目录的 oh-package.json5 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-quick-base64": "file:../../node_modules/@react-native-oh-tpl/react-native-quick-base64/harmony/RNQuickBase64.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

配置 CMakeLists 和引入 GestureHandlerPackage

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_MODULE_DIR}/@react-native-oh-tpl/react-native-quick-base64/src/main/cpp" ./RNQuickBase64)
# 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_quick_base64)
# RNOH_END: manual_package_linking_2

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

#include "RNOH/PackageProvider.h"
#include "SamplePackage.h"
+ #include "RNQuickBase64Package.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
      std::make_shared<SamplePackage>(ctx),
+     std::make_shared<RNQuickBase64Package>(ctx)
    };
}

在 ArkTs 侧引入 Gesture Handler Package

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

+ import { RNQuickBase64Package } from '@react-native-oh-tpl/react-native-quick-base64/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new RNQuickBase64Package(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。

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-tpl/react-native-quick-base64 Releases

Gesture handlers 通用事件数据

以下是提供给 onGestureEventonHandlerStateChange 回调的通用事件数据:

[!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 | Platform | HarmonyOS Support | | ---------------- | --------------------------------------------------------------------------- | ------ | -------- | -------- | | btoa | Encodes a string in base64. | Function | All | yes | | atob | Decodes a base64 encoded string. | Function | All | yes | | toByteArray | Takes a base64 string and returns a byte array. Optional removeLinebreaks removes all \n characters. | Function | All | yes | | byteLength | Takes a base64 string and returns length of byte array. | Function | All | yes | | fromByteArray | Takes a byte array and returns a base64 string. Optional urlSafe flag true will use the URL-safe dictionary. | Function | All | yes | | shim | Adds btoa and atob functions to global. | Function | All | yes | | trimBase64Padding | Trims the = padding character(s) off of the end of a base64 encoded string.
