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 🙏

import {
  encodeQuery,
  decodeQuery,
  parseUrl,
  additionurl
} from "@ztwx/utils";
  • encodeQuery (obj:QueryType)
  • decodeQuery (url:string)

| method | type | desc | | -------- | ------------------------------------- | ---------------------- | | run | <T>(fn:()=>Promise<T>):Promise<T> | 同代码时间,执行一次 |

Example:

import {OneRun} from "@ztwx/utills";
const oneRun =new OneRun();

const run=async()=>{
  console.log("start run.");
  await oneRun.run(()=>new Promise((resolve)=>{
    console.log("run!");
    setTimeout(resolve,1000);
  }))
  console.log("end run.");
}
run();
run();
/**
 * print result:
 * start run
 * start run
 * run!
 * end run
 * end run
 */

QueueRun <T,R>

指定方法,在完成(end)后执行

| method | type | desc | | ------------------- | ------------------------------------------ | ------------------------ | | end | (r:T):void | 完成 | | err | (e:R):void | 错误 | | awaitPromise | ():Promise<T,R> | 等待完成(promise) | | awaitRun | (cb:(r:T)=>void,err?:(e:R)=>void):void | 等待完成 (callback) | | awaitUntilSuccess | ():Promise<T> | 等待直到成功 | | refresh | ():void | 刷新状态,清除等待队列 |

Example:

import {QueueRun} from "@ztwx/utils";
const queueRun=new QueueRun();

const run=async()=> {
  await queueRun.awaitPromise();
  console.log("task end!");
}

run();
run();
console.log("start~");
queueRun.end("success");
run();
/**
 * print result:

Web Compress Image

web图片压缩

| Method | type | desc | | ---------------------------------- | ------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- | | FileCompress.compress | | 压缩图片,返回随机图片名和DataUrl,qualityresolution取0至1,不指定时会按默认算法自动调整 | | dataURLtoArrayBuffer | (dataUrl):Uint8Array | 转换dataUrl为ArrayBuffer | | dataURLtoBlob | (dataUrl):Promise<Blob> | 转换dataUrl为blob | | compressDataUrl | (dataUrl):Promise<dataUrl> | 压缩dataUrl |

})

fileCompress.compress(CompressOpts);

CompressOpts

TaskScheduler

任务调度器工具

每一次程序运行,进行一次任务遍历

API

TaskRule任务规则

| key| type|desc| |---|---|---| |id|string|任务id| |index|number|执行顺序order| |local?|boolean|是否保存本地| |localExpires?|number(seconds)|保存本地时,过期时间。为0或不设置时,local默认不过期|

TaskScheduler 将会按照定义的index顺序,按序执行已推入方法的任务

推入任务方法: taskScheduler.registryTaskRun(opts) 若index:2执行完后,再推入index:0的任务方法,则index:0的任务会后执行。

local为true时,该任务执行成功后将存入本地,未过期前,以后的任务遍历将不再检查该任务。

local不为true, 该任务在每次任务遍历开启后,都会检查该任务。

Method

| method| type| desc| |---|---|---| |constructor|(key:string,manager:StorageInterface):TaskScheduler| TaskScheduler的构造方法,传入自定义key值,和storage管理工具| |initTasksRule|(rules:TaskRule[]):void|初始化定义任务集| |registryTaskRun|(p:{id:string,run:({executeCount,lastExecuteTime}):Promise<void>}):void|注册任务方法,注意run一定返回Promise,代表该方法结束| |pauseCheck|():void|中断任务检查一条任务检查完后会自动进行下一条的检查,该方法可以中断此行为| |restoreCheck|():void|被中断后,必须先调用restoreCheck,才能继续check|

Usage

import {TaskScheduler} from "@ztwx/utils/lib/taskScheduler"
const taskScheduler=new TaskScheduler("task-storage-key",storageManger);
//注册任务
taskScheduler.initTasksRule([
  // TaskRule
  {
    id:"open-dialog1",
    index:0,
  },
  {
    id:"newbie-guide",
    index:2,
    local: true  //新手引导,每个本地只会执行一次
  },
  {
    id:"user-remind",
    index:3,
    local: true,
    localExpires: 60*60*24*12 //用户提醒,每12天执行一次
  }
]);

taskScheduler.registryTaskRun({
  id:"open-dialog1",
  run: ()=>openDialog('dialog content1').then(()=>{...})
})

taskScheduler.registryTaskRun({
  id:"newbie-guide",
  run: async()=>{
    // start 
    await startNewBieGuide();
    //end
  }
});

taskScheduler.registryTaskRun({
  id:"user-remind",
  /**
   * 
   * @param executeCount 已执行次数
   * @param lastExecuteTime 最后一次执行时间(seconds)
   * @returns {Promise<void>}
   */
  run: async({executeCount,lastExecuteTime})=>{
    //toDo...
  }
});

taskScheduler.check(); //开始检查任务

Complex Example 更复杂的案例:

import {TaskScheduler} from "@ztwx/utils/lib/taskScheduler"
const taskScheduler=new TaskScheduler("task-storage-key",storageManger);
taskScheduler.initTasksRule([
  {
    id:"a",
    index:0,
  },
  {
    id:"c",
    index:1,
    local: true,
  }
]);

class IndexPage{
  created(){
    taskScheduler.registryTaskRun({
      id:"a",
      run: async()=>{
        taskScheduler.pauseCheck();
        //离开当前页前,暂停任务检测
        //保证任务检测只会在index Page内执行。
        routeSkip("/xxx/otherPage");
      }
    });
    taskScheduler.registryTaskRun({
      id:"b",
      run:async()=>{...}
    })
  }
  onPageShow(){
    //当前页显示时,恢复检查
    taskScheduler.restoreCheck();
    //因任务未开始,或被中断,所以此处需手动调用开启任务检查
    taskScheduler.check();
  }
  onPageHide(){
    //其他原因当前页被隐藏时,暂停任务检测
    taskScheduler.pauseCheck();
  }
}
import {StorageInterface} from "@ztwx/utils/lib/taskScheduler"
//web
export class WebStorage implements StorageInterface{
  saveVal(key:string,val:Record<string, any>){
    localStorage[key]=JSON.stringify(val);
  }
  getVal(key:string){
    return localStorage[key]?JSON.parse(localStorage[key]): undefined;
  }
}
