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 🙏

树结构工具

字符串

  • randomString: 随机生成指定长度、指定字符集的字符串。

Dom

  • waitForSelector: 等待指定的选择器匹配的元素出现在页面中,如果调用此方法时已经有匹配的元素,那么此方法立即返回。 如果指定的选择器在超时时间后扔不出现,返回 null

杂项

  • defineDictionary: 定义业务字典。 type safe

  • createEnumFromOptions: 通过 options 自动生成对应的 enum, 后期只需要维护 optionstype safe

  • sleep: 等待指定的时间。

  • capitalize: 首字母大写。

  • retry: 重试函数(如果函数抛出错误)直到成功或者达到最大重试次数。

  • objectKeys: 带类型的 Object.keys()

  • omit: 删除 object 对象的指定属性。

  • randomInt: 生成指定范围内[min, max]的整数。

  • awaitTo: Async await wrapper for easy error handling without try-catch。

  • escapeStringRegexp: 把字符串中的特殊字符转义为它可以在正则表达式中使用的形式。

  • isMobile: 判断是否是移动端浏览器。

  • toFixed: Number.toFixed 并移除末尾的零。

类型判断

  • isBoolean

  • isString

  • isNumber

  • isFunction

  • isSymbol

  • isArray

  • isRegExp

  • isMap

  • isPromise

  • isSet

  • isDate

  • isPlainObject

  • isObject

  • isIntegerKey


defineDictionary

定义业务字典, type safe

const { get_MUSIC_TYPE_KEYS, get_MUSIC_TYPE_KV, get_MUSIC_TYPE_MAP, get_MUSIC_TYPE_MAP_BY_KEY, get_MUSIC_TYPE_MAP_BY_VALUE, get_MUSIC_TYPE_OPTIONS, get_MUSIC_TYPE_VALUES, get_MUSIC_TYPE_VK } = defineDictionary([
  {
    key: 'POP',
    value: 1,
    label: '流行音乐',
    color: 'red',
  },
  {
    key: 'ROCK',
    value: 2,
    label: '摇滚音乐',
    color: 'blue',
  },
] as const, 'MUSIC_TYPE') // !!! as const is required for type safe

const MUSIC_TYPE_KEYS = get_MUSIC_TYPE_KEYS()
// ['POP', 'ROCK']
const MUSIC_TYPE_VALUES = get_MUSIC_TYPE_VALUES()
// [1, 2]
const MUSIC_TYPE_KV = get_MUSIC_TYPE_KV()
// { POP: 1, ROCK: 2 }
const MUSIC_TYPE_VK = get_MUSIC_TYPE_VK()
// { 1: 'POP', 2: 'ROCK' }
const MUSIC_TYPE_MAP_BY_KEY = get_MUSIC_TYPE_MAP_BY_KEY()
// POP: {
//   key: 'POP',
//   value: 1,
//   label: '流行音乐',
//   color: 'red',
// },
// ROCK: {
//   key: 'ROCK',
//   value: 2,
//   label: '摇滚音乐',
//   color: 'blue',
// },
const MUSIC_TYPE_MAP_BY_VALUE = get_MUSIC_TYPE_MAP_BY_VALUE()
// 1: {
//   key: 'POP',
//   value: 1,
//   label: '流行音乐',
//   color: 'red',
// },
// 2: {
//   key: 'ROCK',
//   value: 2,
//   label: '摇滚音乐',
//   color: 'blue',
// },
const MUSIC_TYPE_MAP = get_MUSIC_TYPE_MAP()
// { POP: 1, ROCK: 2 }
const MUSIC_TYPE_OPTIONS = get_MUSIC_TYPE_OPTIONS()
// [
//   {
//     key: 'POP',
//     value: 1,
//     label: '流行音乐',
//     color: 'red',
//   },
//   {
//     key: 'ROCK',
//     value: 2,
//     label: '摇滚音乐',
//     color: 'blue',
//   }
// ]
~~createEnumFromOptions~~

通过 options 自动生成对应的 enum, 后期只需要维护 optionstype safe

废弃, 使用 defineDictionary 代替。

// example
const optionsLevel = [
  {
    value: 0,
    label: 'level1',
  },
  {
    value: 1,
    label: 'level2',
  },
] as const // as const is required to make the type safe

const enumLevel = createEnumFromOptions(optionsLevel)
console.log(enumLevel.level1) // 0
console.log(enumLevel['0']) // 'level1'
console.log(enumLevel)
// {
//   "0": "level1",
//   "1": "level2",
//   "level1": 0,
//   "level2": 1
// }
retry

重试函数(如果函数抛出错误)直到成功或者达到最大重试次数。

let callNum = 0
const fn = () => {
  callNum++
  return Promise.reject(new Error('foo'))
}
const [err, res] = await retry(fn, 2, (attemptTime) => {
  return attemptTime * 5
})
// output
// err is Error, res is null, callNum is 3
// execute time is greater than or equal to 15

Tree Utils

breadthFirstTraverse

广度优先遍历。

img

// example
const tree = [
  {
    name: 'a',
    children: [
      { name: 'b' },
    ],
  },
  {
    name: 'c',
  },
]

breadthFirstTraverse(tree, node => console.log(node.name), {
  fieldNames: {
    children: 'Children_', // default is children
  },
})
// output 'a', 'c', 'b'
treeFindNode

查找符合条件的单个节点或多个节点,通过广度优先遍历查找。

// example
const tree = [
  {
    name: 'a',
    children: [
      { name: 'b' },
    ],
  }
]

const res = treeFindNode(tree, node => node.name === 'b') // res is [{ name: 'b' }]
buildTreeFromList

列表结构转树结构。

// example
const list = [
  { uid: '1', title: 'node 1', pid: '' },
  { uid: '1-1', title: 'node 1-1', pid: '1' },
  { uid: '1-2', title: 'node 1-2', pid: '1' },
  { uid: '1-1-1', title: 'node 1-1-1', pid: '1-1' },
]

interface TreeNode {
  key: string
  title: string
  children: TreeNode[]
  pid: string
}

const tree = buildTreeFromList<TreeNode>(list, {
  listFieldNames: { id: 'uid', parentId: 'pid', children: '_Children' },
  treeFieldNames: { id: 'key', parentId: 'pid', children: 'children' },
})
flattenTree

打平,树结构转列表结构。

// example
const tree = {
  id: 1,
  children: [
    {
      id: 2,
    },
  ],
}
const list = flattenTree(tree)
console.log(list)
// output
// [
//   {
//     "ID": 1,
//     "children": [
//       {
//         "ID": 2,
//       },
//     ],
//   },
//   {
//     "ID": 2,
//   },
// ]
treeFindPath

查打符合条件节点的路径。

// example
const tree = [
  {
    name: 'a',
    children: [
      { name: 'b' },
    ],
  },
  {
    name: 'c',
  },
]

const path = treeFindPath(tree, node => node.name === 'b')
console.log(path?.map(v => v.name)) // ['a', 'b']
treeFilterNode

过滤不符合条件的树节点。

const tree = [
  {
    id: 'root',
    children: [
      {
        id: 'child1',
      },
      {
        id: 'child2',
      },
    ],
  },
]
treeFilterNode(tree, node => node.id.includes('1'))
// output
// [
//   {
//     children: [
//       {
//         id: 'child1',
//       },
//     ],
//     id: 'root',
//   },
// ]
