Got is a lightweight and powerful HTTP client for Node.js. It is built on top of the http and https modules and provides a simple, consistent API for making HTTP requests.

Got is one of the most feature-rich http clients in NodeJS ecosystem offering http2, proxy and asynchronous support making it ideal for web scraping.

Got also supports many specific domain integrations like AWS, plugins for various public APIs like github.

Note that Got has some inconsistent behaviors when it comes to web scraping use.
For example, it normalizes http headers which is undesired functionality in scraping and should be disabled.

treq is a Python library for making HTTP requests that provides a simple, convenient API for interacting with web services. It is inspired byt the popular requests library, but powered by Twisted asynchronous engine which allows promise based concurrency.

treq provides a simple, high-level API for making HTTP requests, including methods for GET, POST, PUT, DELETE, etc. It also allows for easy handling of JSON data, automatic decompression of gzipped responses, and connection pooling.

treq is a lightweight library and it's easy to use, it's a good choice for small to medium-sized projects where ease of use is more important than performance.

In web scraping treq isn't commonly used as it doesn't support HTTP2 but it's the only Twisted based HTTP client. treq is also based on callback/errback promises (like Scrapy) which can be easier to understand and maintain compared to asyncio's corountines.

Example Use


const got = require('got');

// GET requests are default and can be made calling the module as is:
const response = await got('https://api.example.com');
console.log(response.body);

// POST requests can send 
const response = await got.post('https://api.example.com', {
    json: { name: 'John Doe' },
});
console.log(response.body);

// handling cookies
import {CookieJar} from 'tough-cookie';

const cookieJar = new CookieJar();

await cookieJar.setCookie('foo=bar', 'https://httpbin.org');
await got('https://httpbin.org/anything', {cookieJar});

// using proxy
import got from 'got';
import {HttpsProxyAgent} from 'hpagent';

await got('https://httpbin.org/ip', {
  agent: {
    https: new HttpsProxyAgent({
      keepAlive: true,
      keepAliveMsecs: 1000,
      maxSockets: 256,
      maxFreeSockets: 256,
      scheduling: 'lifo',
      proxy: 'https://localhost:8080'
    })
  }
});
from twisted.internet import reactor
from twisted.internet.task import react
from twisted.internet.defer import ensureDeferred
import treq

# treq can be used with twisted's reactor with callbacks
response_deferred = treq.get(
    "http://httpbin.org/get"
)
# or POST
response_deferred = treq.post(
    "http://httpbin.org/post",
    json={"key": "value"},  # JSON
    data={"key": "value"},  # Form Data
)

# add callback or errback
def handle_response(response):
    print(response.code)
    response.text().addCallback(lambda body: print(body))
def handle_error(failure):
    print(failure)
# this callback will be called when request completes:
response_deferred.addCallback(handle_response)
# this errback will be called if request fails
response_deferred.addErrback(handle_error)
# this will be called if request completes or fails:
response_deferred.addBoth(lambda _: reactor.stop())  # close twisted once finished

if __name__ == '__main__':
    reactor.run()

#Note that treq can also be used with async/await:
async def main():
    # content reads response data and get sends a get request:
    print(await treq.content(await treq.get("https://example.com/")))

if __name__ == '__main__':
    react(lambda reactor: ensureDeferred(main()))
```
