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 🙏

介绍

基于 axios 的渐进式请求工具。 它不会破坏 axios 原有的能力,帮助您更轻松地处理请求。

快速开始

安装

# 通过 npm, yarn, pnpm 安装

# npm
npm i @varlet/axle -S

#yarn
yarn add @varlet/axle

#pnpm
pnpm add @varlet/axle

发送请求

Axle 归一化了请求函数的参数,并针对不同的业务需求,扩展了更多请求函数,下面是一个简单的例子。

import { createAxle } from '@varlet/axle'

const axle = createAxle(/** @see https://axios-http.com **/)

axle.get('/url', { current: 1, pageSize: 10 }, { headers: {} })
axle.post('/url', { name: 'Axle' }, { headers: {} })

配置

Axle 完全支持 axios 的所有配置能力。

const axle = createAxle(/** @see https://axios-http.com **/)
// axle 内置的 axios ,用法和 axios 一模一样,并且和 axle 共享配置。
const { axios } = axle

axios.defaults.baseURL = 'https://api.example.com'
axios.defaults.headers.common['TOKEN'] = TOKEN
axios.defaults.timeout = 2500

// 添加请求前拦截器
axios.interceptors.request.use(
  (config) => {
    // 请求前处理
    return config
  },
  (error) => {
    // 请求错误处理
    return Promise.reject(error)
  }
)

// 添加请求后返回拦截器
axios.interceptors.response.use(
  (response) => {
    // 任何位于 2xx 范围内的状态码都会导致该函数触发
    // 对响应数据做一些事情
    return response
  },
  (error) => {
    // 任何超出 2xx 范围的状态代码都会导致此函数触发
    // 对响应错误做一些事情
    return Promise.reject(error)
  }
)

Axle & Axios 请求函数

Axle 提供的请求函数可以帮助您更轻松地发送请求。 以下是一些示例,包括与 axios 的比较。 提示:下面只是以 getpost 为例,除此之外 Axle 还支持 optionsheaddeletepatchput 方法。

get

JSON

// axios
axios.get('/url', { params: { id: 1 } })
// axle
axle.get('/url', { id: 1 })

Blob

// axios
axios.get('/url', { params: { id: 1 }, responseType: 'blob' })
// axle
axle.getBlob('/url', { id: 1 })

Text

// axios
axios.get('/url', { params: { id: 1 }, responseType: 'text' })
// axle
axle.getText('/url', { id: 1 })

Document

// axios
axios.get('/url', { params: { id: 1 }, responseType: 'document' })
// axle
axle.getDocument('/url', { id: 1 })

ArrayBuffer

// axios
axios.get('/url', { params: { id: 1 }, responseType: 'arraybuffer' })
// axle
axle.getArrayBuffer('/url', { id: 1 })

Stream

// axios
axios.get('/url', { params: { id: 1 }, responseType: 'stream' })
// axle
axle.getStream('/url', { id: 1 })

post

JSON

和 axios 一致。

// axios
axios.post('/url', { name: 'foo' })
// axle
axle.post('/url', { name: 'foo' })

application/x-www-form-urlencoded

// axios
axios.post('/url', qs.stringify({ name: 'foo' }), {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
  },
})
// axle
axle.postUrlEncode('/url', { name: 'foo' })

multipart/form-data

// axios
const formData = new FormData()
formData.append('name', 'foo')
formData.append('file', new File())

axios.post('/url', formData, {
  headers: {
    'Content-Type': 'multipart/form-data',
  },
})
// axle
axle.postMultipart('/url', { name: 'foo', file: new File() })

实用工具

通知浏览器下载文件

import { download } from '@varlet/axle'

download(await axle.getBlob('/url', { id: 1 }), 'filename')

同时返回成功响应和错误响应

import { withResponse } from '@varlet/axle'

const { response, errorResponse } = await withResponse(axle.get('/url'))

公共 header 操作

const headers = axle.getHeaders()
axle.setHeader('TOKEN', TOKEN)
axle.removeHeader('TOKEN')

内置拦截器

Axle 提供了一些实用的请求/响应拦截器,并且兼容 axle 和 axios。

axios

import { requestHeadersInterceptor, responseTimeoutInterceptor } from '@varlet/axle'

const headersInterceptor = requestHeadersInterceptor({
  headers: () => ({
    token: localStorage.getItem('token'),
    'Axle-Custom-Header': 'Axle-Custom-Header',
  })
})

const retryInterceptor = responseRetryInterceptor({ count: 3 })

axios.interceptors.request.use(
  headersInterceptor.onFulfilled, 
  headersInterceptor.onRejected, 
  headersInterceptor.options
)
axios.interceptors.response.use(
  retryInterceptor.onFulfilled,
  retryInterceptor.onRejected, 
  retryInterceptor.options
)

axle

import { requestHeadersInterceptor, responseTimeoutInterceptor } from '@varlet/axle'

axle.useRequestInterceptor(
  requestHeadersInterceptor({
    headers: () => ({
      token: localStorage.getItem('token'),
      'Axle-Custom-Header': 'Axle-Custom-Header',
    }),
  }),
)

axle.useResponseInterceptor(responseRetryInterceptor({ count: 3 }))

拦截器通用参数

每个内置拦截器都支持 include exclude axiosInterceptorOptions (与 axios 拦截器一致)

include & exclude

用于请求过滤,以确定什么请求应该应用该拦截器,支持指定 methodglob 或者 status,使用方式如下。

axle.useResponseInterceptor(
  responseRetryInterceptor({ 
    count: 3,
    include: ['method:put', 'method:post', 'status:500'],
    exclude: ['/system/**', '/user/addUser', 'status:400']
  }),
)

内置拦截器一览

| 名称 | 描述 | | --- | --- | | requestHeadersInterceptor | 用于自定义请求头 | | requestMockInterceptor | 用于模拟数据 | | requestMd5Interceptor | 用于对请求参数进行 md5 处理 | | responseRetryInterceptor | 用于实现请求异常重试 | | responseStatusInterceptor | 用于拦截状态码 | | responseBlobInterceptor | 用于拦截 blob 类型 | | responseTimeoutInterceptor | 用于归一化超时异常 |

Vue 组合式 API

Axle 提供了 Vue Composition API 风格的用法,封装了请求的 加载状态, 错误状态, 请求的上下行进度返回数据生命周期 等等,并继承了 axios 的所有配置。

<script setup>
import { createAxle } from '@varlet/axle'
import { createUseAxle } from '@varlet/axle/use'

const axle = createAxle(/** @see https://axios-http.com **/)

const useAxle = createUseAxle({
  axle,
  // 可选项: useAxle 的默认 immediate
  immediate: true,
  // 可选项: useAxle 的默认 onTransform
  onTransform: (response) => response,
})

const [users, getUsers, { loading, error, uploadProgress, downloadProgress, abort }] = useAxle({
  // 请求初始化数据
  value: [],
  // 请求方法
  method: 'get',
  // 请求地址, 可以是 getter 函数
  url: '/user',
  // 是否立即发送请求, 默认值: false
  immediate: true,
  // 请求前是否需要重置 value, 默认值: false
  resetValue: true,
  // 重置 value 是否对 value 进行拷贝
  // 设置为 true 时, 使用 JSON.parse(JSON.stringify(value)) 进行拷贝
  // 设置为一个函数时, 该函数将作为拷贝函数对 value 进行拷贝, 如 v => _.cloneDeep(v)
  cloneResetValue: true,
  // 请求参数, 默认值: {}, 可以是 getter 函数
  params: { current: 1, pageSize: 10 },
  // Axios 配置, see https://axios-http.com, 可以是 getter 函数
  config: { headers: {} },
  // 生命周期
  onBefore(refs) {
    const { data, loading, error, uploadProgress, downloadProgress } = refs
    console.log(data.value, loading.value, error.value, uploadProgress.value, downloadProgress.value)
    // 处理请求前逻辑
  },
  onTransform(response, refs) {
    // 处理数据转换,转换后的数据将成为 users 的值。
    return response.data
  },
  onSuccess(response, refs) {
    // 处理请求成功逻辑
  },
  onError(error, refs) {
    // 处理请求错误逻辑
  },
  onAfter(refs) {
    // 处理请求结束逻辑,无论成功失败都会触发。
  },
})
</script>

<template>
  <span>{{ users }}</span>
  <span>{{ loading }}</span>
  <span>{{ error }}</span>
  <span>{{ uploadProgress }}</span>
  <span>{{ downloadProgress }}</span>
  <button @click="getUsers">发送请求</button>
  <button @click="abort">中断请求</button>
</template>

并行请求实用工具

Axle 提供了一些并行请求处理工具,请参考以下示例。

<script setup>
import { createAxle } from '@varlet/axle'
import { createUseAxle, useValues, useAverageProgress, useHasLoading } from '@varlet/axle/use'

const axle = createAxle(/** @see https://axios-http.com **/)

const useAxle = createUseAxle({ axle })

const [users, getUsers, { loading: isUsersLoading, downloadProgress: usersDownloadProgress }] = useAxle({
  value: [],
  method: 'get',
  url: '/user',
})

const [roles, getRoles, { loading: isRolesLoading, downloadProgress: rolesDownloadProgress }] = useAxle({
  value: [],
  method: 'get',
  url: '/role',
})

// 所有请求结束时,loading 为 false
const loading = useHasLoading(isUsersLoading, isRolesLoading)
// 所有请求结束时,downloadProgress 为 1
const downloadProgress = useAverageProgress(usersDownloadProgress, rolesDownloadProgress)
// Ref<[
//   [{ name: 'foo' }, { name: 'bar' }],
//   [{ role: 'admin' }, { role: 'user' }]
// ]> <-
// [
//   Ref<[{ name: 'foo' }, { name: 'bar' }]>,
//   Ref<[{ role: 'admin' }, { role: 'user' }]>
// ]
const usersRoles = useValues(users, roles)

function sendAllRequest() {
  // parallel
  getUsers()
  getRoles()
}
</script>

<template>
  <span>{{ usersRoles }}</span>
  <span>{{ loading }}</span>
  <span>{{ downloadProgress }}</span>
  <button @click="sendAllRequest">发送全部请求</button>
</template>
