A Ruby client library for interacting with FHIR (Fast Healthcare Interoperability Resources) servers, supporting multiple FHIR versions and formats.
FHIR Client is a Ruby library that provides a comprehensive interface for working with FHIR (Fast Healthcare Interoperability Resources) servers. It allows developers to perform CRUD operations, search, transactions, and other FHIR-specific tasks across multiple FHIR versions (R5, R4B, R4, STU3, DSTU2) and data formats (JSON/XML). The library solves the problem of building interoperable healthcare applications by abstracting the complexities of the FHIR standard into a clean Ruby API.
Ruby developers building healthcare applications, health IT systems, or interoperability tools that need to interact with FHIR-compliant servers. It's particularly useful for teams working on electronic health records (EHR), health data exchanges, or clinical research platforms.
Developers choose this library because it offers the most complete Ruby implementation of the FHIR specification with support for all major versions and features. Its dual-mode interface (simple ActiveRecord-style and advanced low-level) provides flexibility for different use cases, while built-in OAuth2 support and comprehensive operation coverage make it production-ready for healthcare applications.

Supports FHIR versions from DSTU2 to R5 with auto-detection, ensuring compatibility with diverse healthcare systems and servers, as shown in the version switching examples.
Handles both JSON and XML representations seamlessly, allowing integration with servers using different formats via methods like default_json and default_xml.
Implements all CRUD operations, transactions, batches, search, and FHIR-specific operations like $validate, covering the full specification as detailed in the README examples.
Provides OAuth2 authentication workflows out of the box, with methods to fetch metadata from server conformance and set up auth, simplifying secure access.
Offers an ActiveRecord-like interface for simplicity and a low-level advanced mode for full control, catering to different developer needs as described in the basic and advanced usage sections.
The dual-mode design can lead to confusion or inconsistent codebases, with the advanced mode being less intuitive and requiring more boilerplate, as acknowledged in the README.
Locked into the Ruby ecosystem, making it unsuitable for polyglot projects or teams using other languages, with no cross-platform or language-agnostic alternatives offered.
The abstraction layer and model handling might introduce overhead compared to raw HTTP requests, especially for high-volume operations or large FHIR bundles, though not explicitly benchmarked.
Lacks built-in support for asynchronous or concurrent request handling, which could be a bottleneck for real-time healthcare applications needing high throughput.
