node.js is made for IoT - node.HH 07/16, Hamburg by Michael Kuehne

Every device gets connected…from coffee machine to fridge over vibrator. It looks like that every hardware manufacturer wants to be part of the game. That’s great and this trend creates lots of cool opportunities for developers.But the rapid growth of different protocols and in particular proprietary implementations makes it hard to stay connected or to get connected in the first place.But lucky us! Node.js is a great solution for IoT.
In this talk I want to outline why node.js is an great choice for IoT projects and why non-blocking IO model is so important for IoT. Furthermore I want to show you what’s the easiest why to get started, if your home is a jungle of different devices.

1. is made for IoT Michael Kuehne Head of Dev @ cybus
2. Who are these IoT Developers? Some Numbers Javascript = Prefered Language of ~ 58% IoT Developers ~ 56% IoT Developers = Hobbyists with Non-IoT Background What are they develop? App for Existing Device (Smart Watch) Standalone Device (Fitness Band) Integ. Limited # of Sensors (Hub) Integ. Devices in Network (Smart City) Combining Data from Mult. Sources (Health App) Data Aggreg. From Exisitng Devices (Air Quality) Back-end Development VisionMobile „IoT Developer Landscape 2015“
4. Cybus: A Middleware for the Industrial Internet of Things Security Monitoring Maintenance Efficiency Sovereignty Async
5. Why Node.js?   Single Threaded   Event-Driven, Non Blocking I/O Model   Speed, Scalability & Efficiency of JS and V8   Well-proven for APIs & Microservice Architecture   Well-developed IoT Modules „The Node.js community made node.js THE platform for IoT“
6. Supported Protocols
7. MQTT Protocol Open Industry Standard (by OASIS) M2M connectivity Protocol Lightweight Publish/Subscribe Protocol Data Agnostic Small Footprint Low Bandwith (min. size 2 bytes) TLS & Certificates
8. MQTT Basics Topics io/cybus/dobot/status/coordinates io/cybus/dobot/command/coordinates Messages [io/cybus/dobot/status/coordinates] -0.4976327,13.7116192 Quality of Service Levels 0 – best effort 1 – deliver at least once 2 – deliver exactly once io/cybus/+/status/coordinates io/cybus/dobot/status/#
9. MQTT Publish/Subscribe MQTT Broker Monitoring Maintenance publish: -0.49...,13.71... publish: -0.49...,13.71... subscribe subscribe publish: -0.49...,13.71... Topic: io/cybus/dobot/status/coordinates io/cybus/dobot/command/coordinates
10. MQTT & Node.js Client MQTT.js Bridge Ponte (MQTT <> REST API <> CoAP) Broker Mosca (written in node.js) Mosquitto (open source) VerneMQ (enterprise – open source) HiveMQ (enterprise – commercial)
11. Demo Time Let‘s move...
12. But how?
13. Node-RED A visual tool for wiring the Internet of Things created by IBM Pulls different device APIs and online services together Extendable with plugins written in node.js Written in node.js Rapid Prototyping for IoT Wanna know more!? Checkout meetup.com/Node-RED-Hamburg
14. Demo Time Let‘s talk...
15. But there‘s so much more
16. Conclusion Node.js is made for industrial IoT One Language for the whole plattform Less Resources but Speed Great for Microservice Architecture Supports & Integrates different industrial protocols Node-RED
