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...

Please note that since Node.js 19.0.0, http.globalAgent enables keepAlive by default, which means that in Axios, when no httpAgent parameter is passed, keepAlive is also enabled by default.
