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 🙏

使用

图片

import { getImageSize } from 'yuxuannnn_utils';
getImageSize(
  'https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fimg1.doubanio.com%2Fview%2Fgroup_topic%2Fl%2Fpublic%2Fp149704739.jpg&refer=http%3A%2F%2Fimg1.doubanio.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1672539028&t=68d096afa3bd661f6c31acbc55411b09',
).then((imageSize) => {
  console.log(imageSize);
});
import { loadImage } from 'yuxuannnn_utils';

loadImage(
  'https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fnimg.ws.126.net%2F%3Furl%3Dhttp%253A%252F%252Fdingyue.ws.126.net%252F2022%252F0902%252F15034aa2j00rhjnth000yc000hs00qog.jpg%26thumbnail%3D660x2147483647%26quality%3D80%26type%3Djpg&refer=http%3A%2F%2Fnimg.ws.126.net&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1672664938&t=53b76b53f947c93d292001b9a0a3ebaf',
  () => {
    console.log('图片加载完成');
  },
);

懒加载控制器

lazyImageControlLazyImageControl 的实例对象

  • extends用于注册其他 DOM 的滚动事件
  • add添加懒加载配置对象
  • update更新状态,可以在页面开始时手动调用
  • setCanShow用户可以自定义化加载规则
  • removeItem移除某一个图片配置对象
    • 例如组件卸载之后 防止因为调用 hook 带来的闭包泄露问题

事件总线

import { EventBus } from 'yuxuannnn_utils';
const eventBus = new EventBus();

时间

import { formatDate } from 'yuxuannnn_utils';
formatDate(Date.now(), 'YYYY MM DD');

format参考doc

extend

import { inhert } from 'yuxuannnn_utils';
function Parent() {
  this.c = 2;
}
Parent.prototype.a = 1;
function Children() {
  Parent.call(this);
  this.b = 1;
}
inhert(Children, Parent);
const child = new Children();
console.log(child.a, child.b, child.c, Children.prototype);

数学

边界取值

import { boundaryMin, boundary, boundaryMax } from 'yuxuannnn_utils';
const a = boundaryMin(-1, 1); // 1
const b = boundary(101, 1, 100); // 100
const c = boundaryMax(101, 100); // 100
import { getRandomNumber, getRandomString } from 'yuxuannnn_utils';

console.log(getRandomNumber(1, 100)); // 生成一个随机整数,包括min不包括max
console.log(getRandomString(8)); // 生成一个随机的字符串

findMaxInArray获取数组中最大的值,提供自定义对比compare参数函数

findMinInArray获取数组中最小的值,提供自定义对比compare参数函数

对象

辨别对象和数组类型

import { getObjOrArrayType } from 'yuxuannnn_utils';
console.log(getObjOrArrayType([]), getObjOrArrayType({})); // array object

深度克隆

import { deepClone } from 'yuxuannnn_utils';

const a = 1;
console.log(deepClone(a));

const obj = { a: { b: { c: 1 } } };
const cloneObj = deepClone(obj);
cloneObj.a = 27;
console.log(obj, cloneObj);

window

import { getScrollOffset, getViewportOffset } from 'yuxuannnn_utils';

onMounted(() => {
  document.addEventListener('scroll', () => {
    console.log(getScrollOffset()); // 获取滚动条信息
    console.log(getViewportOffset()); // 获取视口尺寸
  });
});

file

getMegabyte获取兆的字节数

getFileSuffix获取文件名后缀

changeFileToBase64将文件对象转换成 base64

changeBuffer将文件进行 hash 解析,生成唯一的文件 hash 信息

util

delay延迟函数一般用于本地开发时模拟服务器延迟

debounce防抖函数

throttle节流函数
