Intro

Progressive request tool based on axios. It does not destroy the original abilities of axios, and helps you process requests more easily.

QuickStart

Install

# Install with npm, yarn or pnpm

# npm
npm i @varlet/axle -S

#yarn
yarn add @varlet/axle

#pnpm
pnpm add @varlet/axle

Send Request

Axle normalizes the parameters of the request function, and expands more request functions for different interface requirements. Here is a simple example.

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: {} })

Config

Axle fully supports all configuration abilities of axios.

const axle = createAxle(/** @see https://axios-http.com **/)
// The built-in axios of the axle, the usage is exactly the same as that of axios, and shares the configuration with the axle.
const { axios } = axle

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

// Add a request interceptor
axios.interceptors.request.use(
  (config) => {
    // Do something before request is sent
    return config
  },
  (error) => {
    // Do something with request error
    return Promise.reject(error)
  }
)

// Add a response interceptor
axios.interceptors.response.use(
  (response) => {
    // Any status code that lie within the range of 2xx cause this function to trigger
    // Do something with response data
    return response
  },
  (error) => {
    // Any status codes that falls outside the range of 2xx cause this function to trigger
    // Do something with response error
    return Promise.reject(error)
  }
)

Axle & Axios Request Functions

The request function provided by Axle can help you send requests more easily. Here are some examples including comparison with axios. Tips: Take get and post as examples below, Axle also supports options, head, delete, patch , put methods.

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

Same with axios.

// 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() })

Utils

Notify the browser to download the file

import { download } from '@varlet/axle'

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

Return both a success response and an error response

import { withResponse } from '@varlet/axle'

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

Common Header Operate

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

Built-in interceptor

axle provides some practical requests/response interceptors, and is compatible with axle and 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 }))

General parameter of the interceptor

Each built-in interceptor supports include exclude axiosInterceptorOptions (same with Axios interceptor).

include & exclude

It is used to request filtering to determine what request should apply the interceptor and support specifying the method、 glob syntax or status code. The usage method is as follows.

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

List of built-in interceptor

Vue Composition API

Axle provides the usage of Vue Composition API style, which encapsulates the loading status, error status, upload and download progress of the request, return data, lifecycle, etc., And inherit all the configuration of axios.

<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,
  // Optional value: Default immediate of the useAxle
  immediate: true,
  // Optional value: Default onTransform of the useAxle
  onTransform: (response) => response,
})

const [users, getUsers, { loading, error, uploadProgress, downloadProgress, abort, resetValue }] = useAxle({
  // Request initial value
  value: [],
  // Request method
  method: 'get',
  // Request url can be a getter function
  url: '/user',
  // Whether to send the request immediately, defaults false
  immediate: true,
  // Whether the value needs to be reset before requesting, defaults false
  resetValue: true,
  // Whether to clone when resetting value, defaults false
  // When set to true, use JSON.parse(JSON.stringify(value)) cloned
  // When set to a function, the set function will be used as the clone function, such as v => _.cloneDeep(v)
  cloneResetValue: true,
  // Request params, defaults {}, can be a getter function
  params: { current: 1, pageSize: 10 },
  // Axios config, see https://axios-http.com can be a getter function
  config: { headers: {} },
  // lifecycle
  onBefore(refs) {
    const { data, loading, error, uploadProgress, downloadProgress } = refs
    console.log(data.value, loading.value, error.value, uploadProgress.value, downloadProgress.value)
    // Do request before
  },
  onTransform(response, refs) {
    // Handle data transform, The transformed data will be the value of users.
    return response.data
  },
  onSuccess(response, refs) {
    // Do request success
  },
  onError(error, refs) {
    // Do request error
  },
  onAfter(refs) {
    // Do request after
  },
})
</script>

<template>
  <span>{{ users }}</span>
  <span>{{ loading }}</span>
  <span>{{ error }}</span>
  <span>{{ uploadProgress }}</span>
  <span>{{ downloadProgress }}</span>
  <button @click="getUsers">Send Request</button>
  <button @click="abort">Abort Request</button>
</template>

Parallel Utils

Axle provides some parallel request processing tools, please refer to the following examples.

<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',
})

// At the end of all requests, loading is false
const loading = useHasLoading(isUsersLoading, isRolesLoading)
// At the end of all requests, downloadProgress is 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">Send All Request</button>
</template>
