Excon is a Ruby library for making HTTP requests. It is designed to be fast and efficient, and is often used as a building block for other Ruby libraries and frameworks.

One of the main features of Excon is its support for persistent connections, which allows it to reuse the same connection for multiple requests, reducing the overhead of establishing a new connection for each request.

Excon also supports streaming requests and responses, which allows you to read or write data to the server incrementally, without having to load the entire response into memory at once.

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.

Example Use


require 'excon'

# GET requests
response = Excon.get('https://jsonplaceholder.typicode.com/posts/1')
puts response.body
puts response.status
puts response.headers

# POST requests
response = Excon.post('https://jsonplaceholder.typicode.com/posts',
  :body => { :title => 'foo', :body => 'bar', :userId => 1 }.to_json,
  :headers => { 'Content-Type' => 'application/json' } )
puts response.body
# 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
