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.
Faraday is a Ruby gem that provides a simple and flexible interface for making HTTP requests. It allows you to create a Faraday connection object, which you can use to send requests and receive responses.
Faraday abstracts away the details of the underlying HTTP client library, so you can use it with different libraries such as Net::HTTP, HTTPClient, typhoeus and others.
Since Faraday can adapt many other HTTP clients it's very popular choice in web scraping.
Highlights
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'
})
}
});
# GET requests
response = Faraday.get('http://httpbingo.org')
put response.status
put response.headers
put response.body
# or use a persistent client session:
conn = Faraday.new(
url: 'http://httpbin.org/get',
params: {param: '1'},
headers: {'Content-Type' => 'application/json'}
)
# POST requests
response = conn.post('/post') do |req|
req.params['limit'] = 100
req.body = {query: 'chunky bacon'}.to_json
end
