sdmx-rest

sdmx-rest (v2.20.0) is a JavaScript client for the SDMX REST API, enabling construction and execution of data, metadata, and availability queries against SDMX-compliant web services. It simplifies building REST URLs, managing predefined service instances, and handling responses with promises. The library is actively maintained, with semantic versioning and regular releases via semantic-release. Unlike raw HTTP clients, it abstracts query parameter construction and service definitions, making it suitable for statistical data retrieval in Node.js (>=10) or browser environments. Its main differentiators are built-in support for common SDMX endpoints (like ECB) and a fluent API for query building.
