Install

npm install http-cookie-agent tough-cookie

When you want to use Node.js global fetch (aka. undici), you should install undici additionally.

npm install undici

Usage

Supported libraries

Node.js global fetch / undici / node:http / node:https / axios / node-fetch / got** / superagent** / request** / needle / phin / @hapi/wreck / urllib etc.

** The library supports cookies by default. You may not need http-cookie-agent.

See also examples for more details.

Node.js global fetch

http-cookie-agent supports global fetch since Node.js v18.2.0.

import { CookieJar } from 'tough-cookie';
import { CookieAgent } from 'http-cookie-agents/undici';

const jar = new CookieJar();
const agent = new CookieAgent({ cookies: { jar } });

await fetch('https://example.com', { dispatcher: agent });

undici

import { fetch } from 'undici';
import { CookieJar } from 'tough-cookie';
import { CookieAgent } from 'http-cookie-agents/undici';

const jar = new CookieJar();
const agent = new CookieAgent({ cookies: { jar } });

await fetch('https://example.com', { dispatcher: agent });

node:http / node:https

import https from 'node:https';

import { CookieJar } from 'tough-cookie';
import { HttpsCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();
const agent = new HttpsCookieAgent({ cookies: { jar } });

https.get('https://example.com', { agent }, (res) => {
  // ...
});

axios

import axios from 'axios';
import { CookieJar } from 'tough-cookie';
import { HttpCookieAgent, HttpsCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

const client = axios.create({
  httpAgent: new HttpCookieAgent({ cookies: { jar } }),
  httpsAgent: new HttpsCookieAgent({ cookies: { jar } }),
});

await client.get('https://example.com');

node-fetch

import fetch from 'node-fetch';
import { CookieJar } from 'tough-cookie';
import { HttpCookieAgent, HttpsCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

const httpAgent = new HttpCookieAgent({ cookies: { jar } });
const httpsAgent = new HttpsCookieAgent({ cookies: { jar } });

await fetch('https://example.com', {
  agent: ({ protocol }) => {
    return protocol === 'https:' ? httpsAgent : httpAgent;
  },
});

got

:warning: got supports cookies by default. You may not need http-cookie-agents.

See https://github.com/sindresorhus/got/tree/v11.8.2#cookies.

import got from 'got';
import { CookieJar } from 'tough-cookie';
import { HttpCookieAgent, HttpsCookieAgent } from 'http-cookie-agent/http';

const jar = new CookieJar();

const client = got.extend({
  agent: {
    http: new HttpCookieAgent({ cookies: { jar } }),
    https: new HttpsCookieAgent({ cookies: { jar } }),
  },
});

await client('https://example.com');

superagent

:warning: superagent supports cookies by default. You may not need http-cookie-agents.

See https://github.com/visionmedia/superagent/blob/v6.1.0/docs/index.md#saving-cookies.

import superagent from 'superagent';
import { CookieJar } from 'tough-cookie';
import { MixedCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();
const mixedAgent = new MixedCookieAgent({ cookies: { jar } });

const client = superagent.agent().use((req) => req.agent(mixedAgent));

await client.get('https://example.com');

request

:warning: request supports cookies by default. You may not need http-cookie-agents.

See https://github.com/request/request/tree/v2.88.1#examples.

import request from 'request';
import { CookieJar } from 'tough-cookie';
import { MixedCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

const client = request.defaults({
  agent: new MixedCookieAgent({ cookies: { jar } }),
});

client.get('https://example.com', (_err, _res) => {
  // ...
});

needle

import needle from 'needle';
import { CookieJar } from 'tough-cookie';
import { MixedCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

await needle('get', 'https://example.com', {
  agent: new MixedCookieAgent({ cookies: { jar } }),
});

phin

import phin from 'phin';
import { CookieJar } from 'tough-cookie';
import { MixedCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

await phin({
  url: 'https://example.com',
  core: {
    agent: new MixedCookieAgent({ cookies: { jar } }),
  },
});

@hapi/wreck

import Wreck from '@hapi/wreck';
import { CookieJar } from 'tough-cookie';
import { HttpCookieAgent, HttpsCookieAgent } from 'http-cookie-agents/http';

const jar = new CookieJar();

const client = Wreck.defaults({
  agents: {
    http: new HttpCookieAgent({ cookies: { jar } }),
    https: new HttpsCookieAgent({ cookies: { jar } }),
    httpsAllowUnauthorized: new HttpsCookieAgent({ cookies: { jar } }),
  },
});

await client.get('https://example.com');

urllib

import { request, setGlobalDispatcher } from 'urllib';
import { CookieJar } from 'tough-cookie';
import { CookieClient } from 'http-cookie-agents/undici';

const jar = new CookieJar();
const agent = new CookieAgent({ cookies: { jar } });
setGlobalDispatcher(agent);

await request('https://example.com');

Using with an asynchronous Cookie store

http-cookie-agent use synchronous CookieJar functions by default.

Therefore, you cannot use an asynchronous Cookie store (e.g. redis-cookie-store) by default.

If you want to use an asynchronous Cookie store, set cookies.async_UNSTABLE to true.

// node:http, node:https
const jar = new CookieJar();
const agent = new HttpsCookieAgent({ cookies: { async_UNSTABLE: true, jar } });

// undici
const jar = new CookieJar();
const agent = new CookieAgent({ cookies: { async_UNSTABLE: true, jar } } });

Using with another Agent library

If you want to use another Agent library, wrap the agent in createCookieAgent.

import https from 'node:https';

import { HttpsAgent as KeepAliveAgent } from 'agentkeepalive';
import { CookieJar } from 'tough-cookie';
import { createCookieAgent } from 'http-cookie-agents/http';

const Agent = createCookieAgent(KeepAliveAgent);

const jar = new CookieJar();
const agent = new Agent({ cookies: { jar } });

https.get('https://example.com', { agent }, (res) => {
  // ...
});

undici

If you want to use another undici Agent library, use CookieClient via factory function.

import { fetch, ProxyAgent } from 'undici';
import { CookieJar } from 'tough-cookie';
import { CookieClient } from 'http-cookie-agents/undici';

const jar = new CookieJar();
const agent = new ProxyAgent({
  factory: (origin, opts) => {
    return new CookieClient(origin, {
      ...opts,
      cookies: { jar },
    });
  },
});

await fetch('https://example.com', { dispatcher: agent });

If you want to use another undici Client library, wrap the client in createCookieClient.

import { fetch, Agent, MockClient } from 'undici';
import { CookieJar } from 'tough-cookie';
import { createCookieClient } from 'http-cookie-agents/undici';

const CookieClient = createCookieClient(MockClient);

const jar = new CookieJar();
const agent = new Agent({
  factory: (origin, opts) => {
    return new CookieClient(origin, {
      ...opts,
      cookies: { jar },
    });
  },
});

await fetch('https://example.com', { dispatcher: agent });
