A Ruby hypermedia agent built on Faraday for navigating REST APIs with link relations.
Sawyer is a Ruby library that acts as a hypermedia agent for interacting with RESTful APIs. It builds on Faraday to provide automatic parsing of link relations from API responses, allowing developers to navigate between related resources without manually constructing URLs. The library simplifies working with hypermedia-driven APIs by treating links as first-class citizens.
Ruby developers building API clients or integrations with RESTful services that follow hypermedia conventions, particularly those working with APIs that provide link relations between resources.
Developers choose Sawyer because it provides a clean, intuitive abstraction for navigating hypermedia APIs without the boilerplate of manual URL construction. Its tight integration with Faraday ensures reliable HTTP handling while adding hypermedia-specific functionality missing from basic HTTP clients.

Automatically parses link relations from API responses and provides methods like `rels[:followers].get` to follow them, reducing manual URL construction as shown in the usage example.
Built on Faraday, leveraging its robust HTTP handling features such as middleware and adapters, ensuring reliable request/response cycles without reinventing the wheel.
Offers a clean interface with methods like `agent.call` and `agent.root.data`, making it intuitive to fetch and navigate resources, as demonstrated in the README code snippet.
Returns structured data objects that encapsulate both data and relationship metadata, enabling easy access to linked resources through properties like `rels`.
Labeled as experimental in the README, which means it may lack stability, have breaking changes, and not be suitable for production without caution.
Specifically designed for hypermedia APIs, so it's ineffective for APIs that don't follow HATEOAS principles, limiting its utility in broader contexts.
The README is minimal and points to external docs, which might be sparse or outdated, making it harder for newcomers to get started.
