How to use the Azure IoT SDKs for Node.js

Devices and data sources in an IoT solution can range from a simple network-connected sensor to a powerful, standalone computing device. Devices may have limited processing capability, memory, communication bandwidth, and communication protocol support. The IoT device SDKs enable you to implement client applications for a wide variety of devices.

The SDK team publishes the SDKs as npm packages:

• Azure IoT Hub Device SDK
  • Device Client
  • MQTT Transport
  • AMQP Transport
  • HTTP Transport
• Azure IoT Hub Service SDK
  • Service SDK
• Azure IoT Hub Device Provisioning Service: Device SDK
  • Device Client
  • MQTT Transport
  • AMQP Transport
  • HTTP Transport
  • TPM Security Client
  • x509 Security Client
• Azure IoT Hub Device Provisioning Service: Service SDK
  • Service SDK

• Working with the SDKs code: if you are working with the SDK's code to modify it or to contribute changes, then you can clone the repository and build the libraries following these instructions.

Long Term Support

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.

A new LTS version will be created every 6 months. The lifetime of an LTS branch is currently planned for one year. 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.

Schedule¹

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

NPM Package	Github Branch	LTS Status	LTS Start Date	Maintenance End Date	Removed Date
1.7.x	lts_09_2018	Deprecated	2018-09-16	2019-09-16	2020-03-09
1.11.x	lts_09_2019	Active	2019-09-09	2020-03-09	2020-09-19
