Critical Upcoming Change Notice

All Azure IoT SDK users are advised to be aware of upcoming TLS certificate changes for Azure IoT Hub and Device Provisioning Service that will impact the SDK's ability to connect to these services. In October 2022, both services will migrate from the current Baltimore CyberTrust CA Root to the DigiCert Global G2 CA root. There will be a transition period beforehand where your IoT devices must have both the Baltimore and Digicert public certificates installed in their certificate store in order to prevent connectivity issues.

Devices with only the Baltimore public certificate installed will lose the ability to connect to Azure IoT hub and Device Provisioning Service in October 2022.

To prepare for this change, make sure your device's certificate store has both of these public certificates installed.

For a more in depth explanation as to why the IoT services are doing this, please see this article.

New to the Azure IoT Node.JS SDK?

Try a Device Sample: Create a basic Node.js application following one of the device client library samples provided.

Components

The Azure IoT Node.js SDK enables developers to create IoT solutions written in Node.js for the Azure IoT platform. It is composed of the following client libraries:

  • Device Client Library: to connect devices and IoT Edge modules to Azure IoT Hub. API Reference | README | Configuration Options
    • Note: IoT Edge for Node.js is scoped to Linux containers & devices only. Learn more about using Linux containers for IoT edge on Windows devices.
  • Service Client Library: enables developing back-end applications making use of Azure IoT Hub. API Reference
  • Provisioning Device Client Library: to connect devices to the Azure IoT Provisioning Service. API Reference
  • Provisioning Service Client Library: enables developing back-end applications making use of the Azure IoT Provisioning Service. API Reference

Platform Compatibility

The Azure IoT SDK for Node.js supports the LTS and Current versions of the Node.js runtime.

Releases

The Node SDK offers releases for new features, critical bug fixes, and Long Term Support (LTS). NPM package versioning follows semantic versioning, x.y.z. or major.minor.patch. Any time the version is updated, it will be tagged x.y.z.

New Features and Critical Bug Fixes

New features and critical bug fixes (including security updates) will be released on the main branch. These releases will be tagged using the date formatted yyyy-mm-dd. A feature release will bump the minor version and reset the patch version to 0. A critical bug fix will bump the patch version only.
