aws-iot-device-sdk-v2

AWS IoT SDK for Javascript v2

Next generation AWS IoT Client SDK for Javascript.

This project is in DEVELOPER PREVIEW while we gather feedback on interfaces and use cases. Please file issues and feature requests. Expect breaking API changes as we incorporate feedback. Until this project is promoted to General Availability, we advise you use the previous SDK for a stable development environment.

This SDK is built on the AWS Common Runtime, a collection of libraries (1, 2, 3, 4, 5 ...) written in C to be cross-platform, high-performance, secure, and reliable. The libraries are bound to JS by the awscrt package.

The aws-crt package can be installed via npm

npm install aws-crt

Integration with AWS IoT Services such as Device Shadow and Jobs is provided by code that been generated from a model of the service.

Installation

Samples

node/pub_sub

This sample uses the Message Broker for AWS IoT to send and receive messages through an MQTT connection. On startup, the device connects to the server, subscribes to a topic, and begins publishing messages to that topic. The device should receive those same messages back from the message broker, since it is subscribed to that same topic. Status updates are continually printed to the console.

Source: samples/node/pub_sub

Run the sample like this:

npm install
node dist/index.js --endpoint <endpoint> --root-ca <file> --cert <file> --key <file>

Your Thing's Policy must provide privileges for this sample to connect, subscribe, publish, and receive.
