Introduction to Azure IoT Hub: Follow this guide to learn how to set up an IoT Hub and IoT Hub devices.

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

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 to Azure IoT Hub. API Reference
• 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

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

The project offers a Long Term Support (LTS) version to allow users that do not need the latest features to be shielded from unwanted changes.

The maintenance lifetime of an LTS branch is currently planned for 12 months. LTS branches receive all bug fixes that fall in one of these categories:

• security bugfixes
• critical bugfixes (crashes, memory leaks, etc.)

No new features or improvements will be picked up in an LTS branch.

LTS branches are named lts_mm_yyyy, where mm and yyyy are the month and year when the branch was created. An example of such a branch is lts_07_2017.

Below is a table showing the mapping of the LTS branches to the package versions released

¹ All scheduled dates are subject to change by the Azure IoT SDK team.

New LTS branches will generally be released around the midpoint of the current LTS.
