About
HTTP (The Gem! a.k.a. http.rb) is an easy-to-use client library for making requests
from Ruby. It uses a simple method chaining system for building requests, similar to
Python's Requests.
Under the hood, http.rb uses the llhttp parser, a fast HTTP parsing native extension.
This library isn't just yet another wrapper around Net::HTTP
. It implements the HTTP
protocol natively and outsources the parsing to native extensions.
Why http.rb?
-
Clean API: http.rb offers an easy-to-use API that should be a
breath of fresh air after using something like Net::HTTP.
-
Maturity: http.rb is one of the most mature Ruby HTTP clients, supporting
features like persistent connections and fine-grained timeouts.
-
Performance: using native parsers and a clean, lightweight implementation,
http.rb achieves high performance while implementing HTTP in Ruby instead of C.
Installation
Add this line to your application's Gemfile:
gem "http"
And then execute:
$ bundle
Or install it yourself as:
$ gem install http
Inside of your Ruby program do:
require "http"
...to pull it in as a dependency.
Documentation
Please see the http.rb wiki
for more detailed documentation and usage notes.

Basic Usage
Here's some simple examples to get you started:
>> HTTP.get("https://github.com").to_s
=> "\n\n\n<!DOCTYPE html>\n<html lang=\"en\" class=\"\">\n <head prefix=\"o..."
That's all it takes! To obtain an HTTP::Response
object instead of the response
body, all we have to do is omit the #to_s
on the end:
>> HTTP.get("https://github.com")
=> #<HTTP::Response/1.1 200 OK {"Server"=>"GitHub.com", "Date"=>"Tue, 10 May...>
We can also obtain an HTTP::Response::Body
object for this response:
>> HTTP.get("https://github.com").body
=> #<HTTP::Response::Body:3ff756862b48 @streaming=false>
The response body can be streamed with HTTP::Response::Body#readpartial
.
In practice, you'll want to bind the HTTP::Response::Body
to a local variable
and call #readpartial
on it repeatedly until it returns nil
:
>> body = HTTP.get("https://github.com").body
=> #<HTTP::Response::Body:3ff756862b48 @streaming=false>
>> body.readpartial
=> "\n\n\n<!DOCTYPE html>\n<html lang=\"en\" class=\"\">\n <head prefix=\"o..."
>> body.readpartial
=> "\" href=\"/apple-touch-icon-72x72.png\">\n <link rel=\"apple-touch-ic..."
>> body.readpartial
=> nil
Supported Ruby Versions
This library aims to support and is tested against
the following Ruby versions:
- JRuby 9.3
- Ruby 2.6
- Ruby 2.7
- Ruby 3.0
- Ruby 3.1
- Ruby 3.2
- Ruby 3.3
If something doesn't work on one of these versions, it's a bug.
This library may inadvertently work (or seem to work) on other Ruby versions,
however support will only be provided for the versions listed above.
If you would like this library to support another Ruby version or
implementation, you may volunteer to be a maintainer. Being a maintainer
entails making sure all tests run and pass on that implementation. When
something breaks on your implementation, you will be responsible for providing
patches in a timely fashion. If critical issues for a particular implementation
exist at the time of a major release, support for that Ruby version may be
dropped.
