Debugging

I’m certainly sure that along the way you will find some cache behavior that is not the expected to the current situation. To help with that, the library has a separate robust build with support to debug logs enabled.

You can use it by changing the setupCache import:

EcmaScriptCommon JSBrowserSkypack

import Axios from 'axios';

// Only import from `/dev` where you import `setupCache`.
import { setupCache } from 'axios-cache-interceptor'; 
import { setupCache } from 'axios-cache-interceptor/dev'; 

// same object, but with updated typings.
const axios = setupCache(Axios, {
  debug: console.log 
});

const Axios = require('axios');

// Only import from `/dev` where you import `setupCache`.
const { setupCache } = require('axios-cache-interceptor'); 
const { setupCache } = require('axios-cache-interceptor/dev'); 

// same object, but with updated typings.
const axios = setupCache(Axios, {
  debug: console.log 
});

const Axios = window.axios;

// Choose development bundle.
const { setupCache } = window.AxiosCacheInterceptor;

// same object, but with updated typings.
const axios = setupCache(Axios, {
  debug: console.log 
});

import Axios from 'https://cdn.skypack.dev/axios';

// Only import from `/dev` where you import `setupCache`.
import { setupCache } from 'https://cdn.skypack.dev/axios-cache-interceptor'; 
import { setupCache } from 'https://cdn.skypack.dev/axios-cache-interceptor/dev'; 

// same object, but with updated typings.
const axios = setupCache(Axios, {
  debug: console.log 
});

And much more, depending on your context, situation and configuration. Any misbehavior that you find will have a log to explain it.
