Good default configuration for axios in node.js

axios-instance-config.js

const axios = require('axios');
const http = require('http');
const https = require('https');

module.exports = axios.create({
  //60 sec timeout
  timeout: 60000,

  //keepAlive pools and reuses TCP connections, so it's faster
  httpAgent: new http.Agent({ keepAlive: true }),
  httpsAgent: new https.Agent({ keepAlive: true }),
  
  //follow up to 10 HTTP 3xx redirects
  maxRedirects: 10,
  
  //cap the maximum content length we'll accept to 50MBs, just in case
  maxContentLength: 50 * 1000 * 1000
});

//optionally add interceptors here...

In order to use agentkeepalive in axios, you can pass its agents in request config properties httpAgentand httpsAgent.

Something like

const Agent = require('agentkeepalive');
const keepAliveAgent = new Agent({
  maxSockets: 100,
  maxFreeSockets: 10,
  timeout: 60000, // active socket keepalive for 60 seconds
  freeSocketTimeout: 30000, // free socket keepalive for 30 seconds
});

const axiosInstance = axios.create({httpAgent: keepAliveAgent});
...

Thank you!

These
... httpAgent: new http.Agent({ keepAlive: true }), httpsAgent: new https.Agent({ keepAlive: true }), ...

fixed the weird HPE_INVALID_CHUNK_SIZE error when talking to a proxied API server that was not properly set up.

Hi, i would like to ask,
is this for NODE.JS server ? or i also can apply this method in react app ?

This is for node.js only.

@squalvj: Did you ever find a solution for react app? If you could kindly share your solution, would be greatly appreciated!
