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 🙏

实用数据处理函数

使用方式

模块化环境下使用:

npm install @wolfx/data-utils
const DataUtils = require("@wolfx/data-utils").default;
const { SafeArray } = require("@wolfx/data-utils");

import DataUtils, { SafeArray } from "@wolfx/data-utils";

标签引入直接使用:

需要引用预编译的版本,在 dist 目录下。

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>Title</title>
    <script src="../dist/DataUtils.umd.js"></script>
    <script>
      console.log(DataUtils.default.arrayToGroup([1, 2, 3, 4, 5, 6], 2));
      // [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]
    </script>
  </head>
  <body></body>
</html>

Functions

数组分组

将数组分组,返回二维数组。

console.log(DataUtils.arrayToGroup([1, 2, 3, 4, 5, 6], 2)); // [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]

金额格式

输出逗号分隔的金额格式。

console.log(DataUtils.thousandNumFormat(10000)); // 10,000.00

比较版本号

compareVersion(v1, v2)

比较版本号,如果 v1>v2 则返回 true,否则 false

console.log(DataUtils.compareVersion("3.0.11", "3.0.12")); // false

生成 GUID

输出符合规范的 GUID。

console.log(DataUtils.getGUID()); // 4e97b561-a5a9-49da-81d9-a2203ccf62f6

字符长度统计(中文+2)

解决中文字符长度统计问题。

console.log(DataUtils.getStringLength("1个")); // 3

树形数据转换,将扁平结构的数据转换成树型结构

扁平结构转树结构。

const testArray = [
  { id: 1, parentId: null, label: "yyy" },
  { id: 2, parentId: 1, label: "aaa" },
  { id: 3, parentId: 1, label: "bbb" },
  { id: 4, parentId: 2, label: "ccc" },
  { id: 5, parentId: null, label: "ddd" },
];
console.log(
  JSON.stringify(
    DataUtils.flatToTree(testArray, null, {
      pidName: "parentId",
      idName: "id",
    }),
  ),
);
[
  {
    "id": 1,
    "parentId": null,
    "label": "yyy",
    "children": [
      {
        "id": 2,
        "parentId": 1,
        "label": "aaa",
        "children": [
          {
            "id": 4,
            "parentId": 2,
            "label": "ccc",
            "children": []
          }
        ]
      },
      {
        "id": 3,
        "parentId": 1,
        "label": "bbb",
        "children": []
      }
    ]
  },
  {
    "id": 5,
    "parentId": null,
    "label": "ddd",
    "children": []
  }
]

安全的数组类型

import DataUtils, { SafeArray } from "@wolfx/data-utils";
console.log(new SafeArray(undefined)); // []
