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.
Typhoeus is a Ruby library that allows you to make parallel HTTP requests, which can greatly speed up the process of making multiple requests to different servers. It is built on top of the C library libcurl, which is known for its high performance and reliability.
One of the main features of Typhoeus is its ability to make parallel requests. This means that it can send multiple requests at the same time, and wait for all of them to finish before returning the results. This can greatly reduce the time it takes to make multiple requests, as it eliminates the need to wait for each request to complete before sending the next one.
In addition to its parallelism feature, Typhoeus also provides a convenient and easy-to-use Ruby interface for making HTTP requests. It supports all of the common HTTP methods (GET, POST, PUT, DELETE, etc.) and allows you to set various request options, such as headers, timeouts, and authentication. It also supports streaming responses, which allows you to process large responses piece by piece, rather than loading the entire response into memory at once.
Typhoeus is also supports HTTP/2 protocol which provides faster load times and reduced network usage. It also supports streaming which is an essential feature for large data transfer.
Typhoeus is well-documented, actively maintained, and has a large and active community of users. It is widely used in the Ruby ecosystem and is a popular choice for building high-performance web scraping and data-gathering applications.
Note that Typhoeus can also be used as an adapter in popular alternative package Faraday.
Highlights
Example Use
# 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
# GET request
Typhoeus.get("www.example.com")
# POST request
Typhoeus.post("www.example.com/posts", body: { title: "test post", content: "this is my test"})
# make parallel requests:
# hydra is a request queue manager
hydra = Typhoeus::Hydra.hydra
# create request object
first_request = Typhoeus::Request.new("http://example.com/posts/1")
# add complete callbacks
first_request.on_complete do |response|
# callbacks can queue new requests
third_url = response.body
third_request = Typhoeus::Request.new(third_url)
hydra.queue third_request
end
second_request = Typhoeus::Request.new("http://example.com/posts/2")
# queue requests:
hydra.queue first_request
hydra.queue second_request
hydra.run # this is a blocking call that returns once all requests are complete
