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 🙏

#预览API chanjet-plugin-peview

在mutants框架中, 提供预览功能 , 目前提供图片预览, 后续可能支持其他文件预览.

目前支持chanjet平台 , 后期增加微信.

不能脱离mutants框架单独使用.

获取实例

//通过mutants来获取插件实例
const plugin = mutants.plugin.preview;

API

  1. previewImg 预览图片

    参数
    • options Object 设置选项
      • imgList Array 需要预览的图片集合
      • firstIndex number 首先展示第几张图片, 默认值:0
      • canDelete Boolean 是否可以在预览时删除图片, 默认值:false
    • callback function 执行完成后回调
    • [requestId] string 应用自己定义的id , 用于在restore时判断使用 , 选填
    返回值
    • result
      • resultCode 操作结果 0:成功 , 1:失败
      • message 消息
      • body
        • data 如果在预览时删除图片 , 这里会返回被删除的图片数据

用法

//获取插件实例
const plugin = mutants.plugin.preview;

//定义调用参数
const options = {
   imgList : [
     'http://img4.imgtn.bdimg.com/it/u=2134987970,41197490&fm=21&gp=0.jpg' ,
     'http://bbs.zgwg.com.cn/UploadFile/2009-4/200941820512789561.jpg'
   ],
   firstIndex : 0,

};


//定义requestId
//requestId用于在restore时帮助应用判断调用插件的业务或者逻辑.从而根据结果进行后续操作
//预览操作不进行转场,所以在目前情况下不会被销毁,可以选择不传requestId
const requestId = 'PreviewAtDemoPage';


//定义回调
const callback = (rs) => {
  /*
   *  rs = {
   *		resultCode : number,	//0:ok , 1:failed , 2:canceled
   *		message : string,
   *		requestId : string,
   *		body : {
   *			data : Object
   *		}
   *  }
   */

  //调用成功
  if(rs.resultCode == 0){
	//插入应用自己的代码
    console.log(rs.body);

  //调用失败
  }else if(rs.resultCode == 1){
  	//插入应用自己的代码
    console.log(rs.message);

  //用户取消
  }else{
  	//插入应用自己的代码
  }
}




/**
 * 预览图片
 * @param options {JSONObject} 设置
 *  @property options.imgList {Array}  预览图片的集合
 *  @property options.firstIndex  {Number} 首先展示第几张图片, 默认值:0
 * @param callback 执行完成后回调
 * @param [requestId] 应用自己分配的值,用于在restore时判断数据来源进行后续操作.
 */
plugin.previewImg(options , callback , requestId);

mock数据

在浏览器环境中,可以通过mock数据来模拟返回结果 , 可以使用 mutants.plugin.setMockData 来设置mock数据.

具体参考如下:

模拟成功

const mockData = {
  //mock数据中,键名为插件的类名
  PreviewPlugin : {
    status : 'success',
  }
}

//设置mock数据
mutants.plugin.setMockData(mockData);

模拟失败

const mockData = {
  //mock数据中,键名为插件的类名
  PreviewPlugin : {
    status : 'failed',
  }
}

//设置mock数据
mutants.plugin.setMockData(mockData);
