Programming IoT Gateways in JavaScript with macchina.io



In this talk +Günter Obiltschnig will introduce macchina.io (http://macchina.io), a new open source platform for programming Linux-based IoT gateway devices.
macchina.io provides a rich programming environment that allows to build modular applications using both JavaScript and C++. Although macchina.io itself is implemented in C++, based on the POCO C++ Libraries and a couple of other cool frameworks, it integrates the Google V8 JavaScript engine to allow high-level application development in JavaScript.
After a quick overview of macchina.io, we’ll go through a live demo, followed by a few JavaScript programming examples showing how to obtain sensor data, store it in an on-device SQLite database, visualize it using the built-in web server and transmit it to a server using MQTT. I’ll also talk about the C++-to-JavaScript bridging mechanism, which enables using C++ services from JavaScript without having to manually write glue or wrapper code.
