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 🙏

本项目基于 @capacitor/[email protected] 开发。

简介

@capacitor/toast提供了一个通知弹窗,用于向用户显示信息,兼容capacitor的Android、iOS等主流移动平台,本文档只说明在OpenHarmony系统中的使用。

本插件用于在屏幕上显示短暂的消息提示,常用于显示简短的通知或反馈信息,适配OpenHarmony系统的消息提示场景,调用便捷、轻量。

  • OpenHarmony:5.0+

下载安装

通过命令行或手动引入即可快速安装插件,支持从npm仓库获取。

命令行安装(推荐)

安装hionic CLI:

npm install -g hionic

以下两种方式中任选其一即可,无需重复操作:

npm安装:

# 安装插件
npm install @capacitor/toast

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @capacitor/toast

手动引入安装

根据插件源码中 plugin.xml 配置在项目中引入插件,步骤如下:

1. 添加插件配置

根据 plugin.xmlconfig-json 项,通过 target 字段找到 entry 模块中 capacitor.plugins.json 文件,并根据 param 标签添加配置如下:

{
  "pkg": "@capacitor/toast",
  "classpath": "Toast"
}

2. 修改 CMake 配置

根据 plugin.xmlCMakeLists 项,通过 modules-name 字段找到模块 capacitor,路径为 target 字段的 CMakeLists.txt 文件,并添加 add_subdirectorytarget_link_libraries 如下:

#START_ADD_SUBDIRECTORY
// ...
add_subdirectory(Toast)
// ...
#END_ADD_SUBDIRECTORY

// ...

target_link_libraries(capacitor PUBLIC
  // ...
  "-Wl,--whole-archive"
  // ...
  Toast
  // ...
  "-Wl,--no-whole-archive"
)

3. 复制源码文件

根据 plugin.xmlsource-file 项,根据 src 字段找到需要复制的文件,并根据 modules-name 字段和 target-dir 字段找到文件复制的具体模块和目录,具体操作如下:

将源码中src/main/cpp/Toast目录下的Toast.h、Toast.cpp、CMakeLists.txt文件引入到capacitor模块中src/main/cpp/Toast目录下。

将源码中src/main/ets/components/Toast目录下的Toast.ets文件引入到capacitor模块中src/main/ets/components/Toast目录下。

4. 添加 ArkTS 配置

capacitor 模块的 build-profile.json5 文件中,buildOption/arkOptions/runtimeOnly/sources 配置项数组中加入步骤3中拷贝的ets文件路径,具体配置如下:

{
  "buildOption": {
    // ...
    "arkOptions": {
      "runtimeOnly": [
        // ...
        "./src/main/ets/components/Toast/Toast.ets"
        // ...
      ]
    }
  }
}

卸载

# 卸载 toast 插件
hionic plugin remove @capacitor/toast

约束与限制

    position: 'bottom'
  });
};

// 显示顶部、短时间的提示消息
const showShortTopToast = async () => {
  await Toast.show({
    text: '请检查输入',
    duration: 'short',
    position: 'top'
  });
};
