NodeJS - Cookie Jar Support

axios running on NodeJS does not provide Cookie jar support natively. Ideally the library would either provide built in cookie jar functionality or easily accommodate existing cookie jar libraries.

The Request API could be modified to support the following options:

{
...
  // `jar` is a boolean that controls cookie jar support for the request
  jar: true, // default
...
}

or

{
...
  // `jar` is a cookie jar that will be used for the request
  jar: cookieJar, // default
...
}

where

var tough = require('tough-cookie');
var cookiejar = new tough.CookieJar();

Note: Trivial cookie support using tough-cookie can be added by leveraging interceptors:

var tough = require('tough-cookie');
var Cookie = tough.Cookie;
var cookiejar = new tough.CookieJar();

axios.interceptors.request.use(function (config) {
  cookiejar.getCookies(config.url, function(err, cookies) {
    config.headers.cookie = cookies.join('; ');
  });
  return config;
});

axios.interceptors.response.use(function (response) {
  if (response.headers['set-cookie'] instanceof Array) {
    cookies = response.headers['set-cookie'].forEach(function (c) {
      cookiejar.setCookie(Cookie.parse(c), response.config.url, function(err, cookie){});
    });
  }
  return response;
});

would definitely like to see cookies/persistent sessions support in axios. A third party module is a great addition but there’s no guarantee on it’s maintainability in the future.

I was recently trying to do just that (add trivial cookie support) and I’ve used the code sample posted by @nicholasrobinson. Unfortunately I couldn’t make it work like that. It seems that axios.interceptors.request is triggered between the request being made and then callback being executed. So it doesn’t inject the cookie in the request.

I made it work by manually capturing the cookie on the first server response and then manually injecting the cookie into the following requests (which is ugly) like this

function getCookie(response) {
    return response.headers['set-cookie'];
}

function makeRequestWithGivenCookie(cookie) {
    return axios.get('/',{headers: {"Cookie": cookie}});
}

Am I missing something here? BTW axios is great! Cookie support would really be an awesome feature.
