Azure IoT HTTP Base Library

The `azure-iot-http-base` package is an internal library within the Azure IoT Node.js SDKs, providing foundational HTTP-specific components and utilities. It is not intended for direct consumption by most application developers; instead, its functionalities are integrated and exposed through higher-level SDK packages such as `azure-iot-device-http` for device clients and `azure-iothub` for service clients. The current stable version is 1.12.3, released as part of the broader Azure SDKs for Node.js update cadence, which typically occurs every few months. Key differentiators include its specialized focus on HTTP operations within the Azure IoT ecosystem, its role as a low-level transport primitive, and its inclusion of TypeScript type definitions, ensuring robust development practices. It abstracts away the complexities of HTTP communication for IoT-specific scenarios, supporting Node.js versions 14.0.0 and above. Developers should generally rely on the orchestrating device or service SDKs for HTTP-based interactions, as this package handles the underlying mechanics.
