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 🙏

Readme

tiny-import

tiny-import是一个搭配webpack使用的模块引入插件,按照需求一键引入想要的模块

示例

文件目录

|-- dir
    |-- a.js
    |-- b.js
    |-- c.js
import { tinyImport } from 'tiny-import'

const requireList = tinyImport.importAll({
      context: require.context('./dir'),
      include: ['a', 'b']
})

requireList 等于

{
	a: {},
	b: {} 
}

原型

TinyImport


import { TinyImport } from 'tiny-import'

const tinyImport = new TinyImport({
	exclude: 'index'     // 全局排除所有index文件,例如index.js index.jpg
})

const requireList = tinyImport.importAll({
      context: require.context('./dir),
      include: ['a', 'b']
})

原型参数(globalFilter)

用于定义全局的筛选器, 可选的参数有 { exclude, include, excludePath, includePath }

exclude

排除某些文件名的文件(不包含文件后缀)

  • type
    • String 排除文件名等于该字符串的文件
    • Function(name, path) 返回Boolean类型 返回true表示排除,false不排除
      • name表示文件名称 path表示文件路径
    • RegExp 排除匹配文件名
    • Array 可以是一个包含多种条件的数组,任意一个匹配了就会排除
  • default: () => false
include

引入某些文件名的文件(不包含文件后缀)

  • type
    • String 引入文件名等于该字符串的文件
    • Function(name, path) 返回Boolean类型 返回true表示引入,false不引入
      • name表示文件名称 path表示文件路径
    • RegExp 排除匹配文件名
    • Array 可以是一个包含多种条件的数组,数组所有项都匹配了才会引入
  • default: () => true
excludePath | includePath

排除 | 引入匹配文件路径的文件(包含文件后缀)

处理顺序

exclude(Path)和include(Path)可以同时使用,include(Path)具有优先级,即先引入,再排除

// 引入dir文件夹下的所有js文件,但是排除a.js
import { tinyImport } from 'tiny-import'

const requireList = tinyImport.importAll({
      context: require.context('./dir'),
      include: /.js$/,
	  exclude: 'a',
})

tinyImport

如果只需要引用一次,不需要全局筛选器,则可以直接使用tinyImport

tinyImport的默认规则:

  • 排除所有index为文件名的文件,例如index.js index.png
  • 排除所有以_或者:开头的文件,例如_index.js :index.js等
import { tinyImport } from 'tiny-import'

const requireList = tinyImport.importAll({
      context: require.context('./dir),
      include: ['a', 'b']
})

实例方法

importAll
参数
  • context: 必填 引入的文件上下文,希望接受一个require.context()的值,详情查看

  • exclude(Path) | include(Path): 选填 和globleFilter一样, 表示当前引入的筛选器

  • key({ name, path })

    • 选填 Funtion 在exlude和include匹配前调用,用于修改所有文件的文件名
    • name表示文件的原始文件名
    • path表示文件目录
key 方法使用示例
目录
|-- dir
    |-- a.js
    |-- b.js
    |-- c.js
	
import { tinyImport } from 'tiny-import'

const requireList = tinyImport.importAll({
      context: require.context('./dir'),
	  key: ({ name }) => name + name,     // 将所有key变成key+key的类型
	  exclude: 'cc'   // 注意,key方法的调用在exclude之前,所以如果要排除c.js,需要写'cc'
})

{
	aa: {},
	bb: {} 
}
  • value({ file, path, name, key })
    • 选填 Funtion 在exlude和include匹配前调用,用于修改所有文件的内容
    • file表示文件内容
    • name表示文件的原始文件名
    • path表示文件目录
    • key表示经过key函数处理过的文件名
value 方法使用示例
目录
|-- dir
    |-- a.js
    |-- b.js
    |-- c.js
	
import { tinyImport } from 'tiny-import'

const requireList = tinyImport.importAll({
      context: require.context('./dir'),
	  value: ({ file }) => [file],     // 每项都变成数组
})

{
	a: [{}],
	b: [{}],
	c: [{}]
}
  • noSub: 选填 Boolean 是否引入子文件夹的内容,默认是false
importAllType
参数
  • context

  • exclude

  • include

  • excludePath

  • key

  • value

  • noSub 注意,没有includePath参数,该参数会被覆盖

  • fileType: 文件后缀名 String

// 例如要引入所有png类型的文件
importAllType({
    context: require.context('./dir'),
    fileType: 'png'
})

预设的其他类型引入():

  • importJs // 引入js类型
  • importImg // 引入图片
  • importVue // 引入vue组件
  • importJson // 引入json
  • importTs // 引入ts文件

参数

  • context
  • exclude
  • include
  • excludePath
  • key
  • value
  • noSub

如何拓展其他类型?

// 例如想要定义一个方法,用于引入所有的.mbx文件

class TinyImport2 extends TinyImport{
    importMbx(params) {
        return this.importAllType({
            ...params,
            fileType: 'mbx',
        })
    }
}

###下个版本想做的内容?

  • 引入结果按文件目录返回
  • inportAllType支持includePath参数

routeImport

专为vue-router提供的插件,根据路由文件夹目录生成vue-router可用的路由表

我们通过给vue文件取特定格式的名称来指定路由类型,这一灵感来自于nuxt.js,但是略有不同

###使用示例

// 目录
|-- page
      |-- ChildA.vue
      |-- ChildB
      		|-- index.vue
// router.js
import Vue from 'vue'
import VueRouter from 'vue-router'

import { routeImport } from 'tiny-import'

Vue.use(VueRouter)

const routes = routeImport.importRoute({
  context: require.context('../views'),
})

const router = new VueRouter({
  routes,
})

export default router
// 路由
[
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/childb",
        "name":"ChildB",
        "component":{
            "name":"ChildB",
            "components":{ },
        },
        "children":[],
    }
]

实例方法

importRoute

引入路由

参数
  • context 必填
  • root 选填 表示根目录使用哪个路由
// router.js
// 当匹配到/根目录时,显示ChildA.vue
const routes = routeImport.importRoute({
  context: require.context('../views'),
  root: 'ChildA'
})
// 路由
[
	{
        "path":"/",
        "name":"/",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/childb",
        "name":"ChildB",
        "component":{
            "name":"ChildB",
            "components":{ },
        },
        "children":[],
    }
]
  • include 选填 不建议填写
  • excludePath 选填 不建议填写
  • noSub 选填 不建议填写
普通具名式路由(官方文档)

没有任何特殊符号作为文件名的路由,例如ChildA, ChildB, PageA等 推荐使用大写字母开头,驼峰式,路由的path会被转换为小写字母,例如childa, childb, pagea

动态匹配式路由(官方文档)

以:符号开头的路由,例如:DynamicB

这样,任意访问/123 的路由将会匹配到:DynamicB.vue,并且注入this.$route.params = { "dynamicb": "123" }

// 目录
|-- page
      |-- ChildA.vue
      |-- :id#DynamicB.vue
// 路由
[
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/:dynamicb",
        "name":"DynamicB",
        "component":{
            "name":"DynamicB",
            "components":{ },
        },
        "children":[],
    }
]
指定动态参数

以:符号开头,含有#号的路由,例如:id#DynamicC.vue

这样,任意访问/123 的路由将会匹配到:id#DynamicC.vue,并且注入this.$route.params = { "id": "123" }

// 目录
|-- page
      |-- ChildA.vue
      |-- :id#DynamicC.vue
// 路由
[
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/:id",
        "name":"DynamicC",
        "component":{
            "name":"DynamicC",
            "components":{ },
        },
        "children":[],
    }
]
捕获式路由(官方文档)

以@命名的路由,即@.vue,当没有任何路由匹配到时,会匹配到这个组件,一般用来设计404页面

// 目录
|-- page
      |-- ChildA.vue
      |-- ChildB.vue
	  |-- @.vue
// 路由
[
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/childb",
        "name":"ChildB",
        "component":{
            "name":"ChildB",
            "components":{ },
        },
        "children":[],
    },
	{
        "path":"*",
        "name":"@",
        "component":{
            "name":"@",
            "components":{ },
        },
        "children":[],
    }
]
嵌套路由(官方文档)

以文件夹的关系来表示嵌套关系

现在,访问/childb/subchilda将会匹配到SubchildA.vue 记得在ChildB组件内添加路由根节点

// 目录
|-- page
      |-- ChildA.vue
      |-- ChildB
		|-- index.vue
		|-- SubChildA.vue
// 路由
[
    {
        "path":"/childa",
        "name":"ChildA",
        "component":{
            "name":"ChildA",
            "components":{},
        },
        "children":[],
    },
    {
        "path":"/:dynamicb",
        "name":"DynamicB",
        "component":{
            "name":"DynamicB",
            "components":{ },
        },
        "children":[
		     {
                "path":"subchilda",
                "name":"SubChildA",
                "component":{
                    "name":"SubChildA",
                    "components":{},
                },
                "children":[

                ],
            }
		],
    }
]

importComponent

我们推荐把公用组件提取出,单独放在src/component文件夹下 但是仍然有某些组件,只在某些页面使用,我们把他称为该页面的私有组件

在tiny-import中,使用_开头的vue文件会被当做该文件夹下的私有组件,我们提供了importComponent方法,专门用于引入这些私有组件

参数
  • context 必填
  • exclude 选填
  • excludePath 选填 不建议填写
使用示例
// 目录
|-- page
      |-- ChildA.vue
      |-- ChildB
		|-- index.vue
		|-- SubChildA.vue
		|-- _ComponentA.vue
		|-- _ComponentB.vue
// 该_ComponentA(B)不会被添加到路由表中
// 在page/ChildB/index.vue中引入这些组件
import { routeImport } from 'tiny-import'

const components = routeImport.importComponent({
  context: require.context('./')
})

export default {
  name: 'ChildB',
  components,  // 注入组件
  data() {
    return {}
  },
  watch: {},
  computed: {},
  created() {},
  methods: {}
}

// components 等于 :
{
	ComponentA: {
		name: "ComponentA",
		components: { },
	},
	ComponentB: {
		name: "ComponentB",
		components: { },
	}
}

一个含有所有Api的例子

|-- page
      |-- :id#DynamicA.vue
      |-- @.vue
      |-- ChildA.vue
      |-- ChildB
      |   |-- _ComponentB.vue
      |   |-- index.vue
      |   |-- _ComponentA
      |       |-- _ComponentC.vue
      |       |-- index.vue
      |-- ChildC
          |-- :id#DynamicSubChildC.vue
          |-- @.vue
          |-- SubChildA.vue
          |-- SubChildB.vue
          |-- index.vue
// 路由表
[
    {
        "path": "/",
        "name": "/",
        "component": {}
    },
    {
        "path": "/childa",
        "name": "ChildA",
        "component": {},
        "children": []
    },
    {
        "path": "/childb",
        "name": "ChildB",
        "component": {},
        "children": []
    },
    {
        "path": "/childc",
        "name": "ChildC",
        "component": {},
        "children": [
            {
                "path": "subchilda",
                "name": "SubChildA",
                "component": {},
                "children": []
            },
            {
                "path": "subchildb",
                "name": "SubChildB",
                "component": {},
                "children": []
            },
            {
                "path": ":id",
                "name": "DynamicSubChildC",
                "component": {},
                "children": []
            },
            {
                "path": "*",
                "name": "@",
                "component": {},
                "children": []
            }
        ]
    },
    {
        "path": "/:dynamicb",
        "name": "DynamicB",
        "component": {},
        "children": []
    },
    {
        "path": "/:id",
        "name": "DynamicA",
        "component": {},
        "children": []
    },
    {
        "path": "*",
        "name": "@",
        "component": {},
        "children": []
    }
]

下一个版本要实现的

  • 更直观更明智的文件标识符设计
  • 允许开发者自定义文件标示符
  • 允许在vue文件内部定义路由类型,而不是在文件名上
  • 在文件夹的index.vue中自动引入私有组件,而不用手动引入它

希望实现的内容

  • 将整个模块做成webpack的一个loader
  • 摆脱require.context依赖,可以在node中使用
  • 用.tiignore或者ti.config.js等文件代替繁琐的exclude(include)
