axios-cache-adapter

Caching adapter for axios

Adapted from superapi-cache by @stephanebachelier

Install

Using npm

npm install --save axios-cache-adapter

Or bower

bower install --save axios-cache-adapter

Or from a CDN like unpkg.com

<script type="text/javascript" src="https://unpkg.com/axios-cache-adapter"></script>

PS: For bower users there is a limitation, this library uses lodash-es as a dependency which is not published on bower. If you use bower, use the bundled version of the lib dist/cache.bundled.js

Usage

You can use the adapter directly

import axios from 'axios'
import { setupCache } from 'axios-cache-adapter'

const cache = setupCache({
  maxAge: 15 * 60 * 1000
})

const api = axios.create({
  adapter: cache.adapter
})

api({
  url: 'http://some-rest.api/url',
  method: 'get'
}).then(response => {
  // Do something fantastic with response.data \o/
})

Or you can get an instance of axios pre-configured with the cache adapter

import { setup } from 'axios-cache-adapter'

const api = setup({
  cache: {
    maxAge: 15 * 60 * 1000
  }
})

api({
  url: 'http://some-reset.api/url',
  method: 'get'
}).then(response => {
  // Do something awesome with response.data \o/
})

API

setupCache(options)

Create a cache adapter instance. Takes an options object to configure how the cached requests will be handled, where they will be stored, etc.

Options

• maxAge {Number}: Maximum time for storing each request in milliseconds, defaults to 15 minutes (15 * 60 * 1000)
• store {Object}: An instance of localForage, defaults to a custom in memory store
• clearOnStale {Boolean}: Clear cache when it is stale, defaults to true
• exclude {Object}: Object defining which kind of requests should be excluded from cache
  • filter {Function}: A method which receives the request and returns true to exclude request from cache, defaults to null
  • query {Boolean}: If true all requests containing a query will be excluded, defaults to false
  • paths {Array}: An Array of regular expressions to match against request URLs, if a match is found it will be excluded, defaults to []
• debug {Boolean}: Print some logs to console, defaults to false

Returns

setupCache() returns an object containing the configured adapter and the cache store.

setup(options)

Create an axios instance pre-configured with the cache adapter. Takes an options object to configure the cache and axios at the same time.

Options

• cache {Object}: Same options as the setupCache method

All the other parameters passed in the options will be passed directly to the axios.create method.

Returns

setup() returns an instance of axios pre-configured with the cache adapter.
