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 🙏

yh-scriptloader

v1.0.13

Published

script loader

Readme

yh-scriptloader

功能:

同步/异步加载 html <script> 标签

安装:

npm i yh-scriptloader --save

用法:

1. 引入

    import { createLoaders } from "yh-scriptloader";

2. 创建 loaders

    const mapjs = `https://webapi.amap.com/maps?v=2.0&key=${gaodekey}`;

    const mapUI = "https://webapi.amap.com/ui/1.1/main.js";

    const srcs = [
      [
        { src: mapjs },
        { src: mapUI }
      ]
    ];
    const loaders = createLoaders(srcs);

3. 加载回调

  • 普通回调风格
   loaders.loading((res) => {
      if(res.loaded){
          this.mapSetUp();
      }else{
          console.log(res);
      }
    });
  • Promise风格
  loaders
    .loading()
    .then((result) => {
      console.log("scriptloader - loading", result);
    })
    .catch((err) => {
      console.log("scriptloader - loading", err);
    });

API :

创建加载器

createLoaders(parms)

  • 返回类型 YHLoaders

  • parms(asyncArray) - Array.<syncArray>

最外层为 asyncArray - 里层为 syncArray

即:

  • asyncArray 中的所有单元为异步加载
  • syncArray 中的所有单元为同步加载

例如

使用异步加载

    const srcs = [
        [{ src: mapjs }],
        [{ src: mapUI }]
    ];

使用同步加载

    const srcs = [
      [
        { src: mapjs },
        { src: mapUI }
      ]
    ];

加载与回调

.loading(callback)

| 序号 | 参数名称 | 类型 | | :---: | :------: | :------: | | 1 | callback | Function |

直接加载

YHloading(parms)

| 序号 | 参数名称 | 类型 | | :---: | :------: | :----------------------------------------------------------: | | 1 | parms | Array.<syncArray> 同 createLoaders(parms) |

  • 普通回调风格
  YHloading(srcs, () => {
    console.log("scriptloader - loading", window.AMap);
  });
  • Promise风格
  YHloading(srcs)
    .then((result) => {
      console.log("scriptloader - loading", result);
    })
    .catch((err) => {
      console.log("scriptloader - loading", err);
    });
