axios-anti-dup-req-adapter v0.1.0

axios-anti-dup-req-adapter

Axios adapter which prevents instance from sending duplicate requests

• this adapter generates a hash code signature from an axios request
• requests have the same url, method, params, data, responseType result the same signature
• requests which have the same signature are treated as duplicate requests
• before sending a request to server, this adapter will check whether there is a pending request which has the same signature (let's call the pending one primary request)
  • if so, the current request will not be sent to server, it will be redirected to the primary request
  • if not, the current request will be set into a cache as the primary request
  • when the primary request is fulfilled, it will be cleared from the cache

Install

npm install axios-anti-dup-req-adapter

Quick Start

Basic usage

import axios from 'axios'
import adapter from 'axios-anti-dup-req-adapter'

const instance = axios.create({ baseURL: 'http://example.base', adapter })

// you can use the feature of the adapter now
instance.get(/** your code*/)

Disable cache

use config.useAdra: false to disable cache, this property defaults to true

/**
 * sometimes you don't want to use the cache
 * for example your request needs a different response for each invocation
 */
instance.get('/random/number', { useAdra: false })

Use your customized adapter

inside this adapter, we use axios.defaults.adapter as network request adapter by default, if you wanna use your customized adapter, do it like this

import axios from 'axios'
import adapter, { adapterEnhancer } from 'axios-anti-dup-req-adapter'

const myAdapter = /* implement your adapter / const instance = axios.create({ baseURL: 'http://example.base', { adapter: adapterEnhancer(myAdapter) } })

// you can use the feature of both adapters now instance.get(/* your code/)
