excon

Excon is a Ruby HTTP client library designed to provide fast, robust access to web resources. It emphasizes low-level control, efficient connection handling, and a simple API for making HTTP requests. Excon is used across Ruby projects that require performance and reliability, including integration layers in other libraries.

The library uses persistent connections, streaming, and a middleware-driven architecture. The middleware stack allows users to modify requests, responses, and errors as they pass through Excon. It supports streaming request bodies and responses, which helps handle large payloads without buffering. Excon's design aims for thread-safety and predictable resource usage, making it suitable for high-concurrency applications. It abstracts away the underlying socket implementation behind a consistent interface.

Usage and ecosystem: as a gem, Excon can be used by direct calls like Excon.get, Excon.post, or by constructing Excon::Connection objects for reuse. It integrates with Ruby ecosystems such as Fog and other HTTP-driven libraries to provide robust network communication features.

Excon is open-source software with ongoing community development. It is distributed via RubyGems and hosted on public repositories, where users can contribute, report issues, and propose enhancements.
