Introduction to PageNodes, Browser-Based IoT Framework #IoTuesday #IoT
We have been working on PageNodes since October of 2015, originally a fork of the user interface from IBM’s Node-Red project which runs IoT processes in Nodejs. We then built a new flow execution engine completely in browser which removes the need of maintaining external services. IBM did an amazing job with creating a social atmosphere for developing inter machine messaging; we wanted to scale that concept out infinitely by removing any friction in getting started.
PageNodes uses the flow-based programming idea of node-red, with it’s full functionality packaged completely in the browser, to create a great tool for anyone to structure tasks for all their IoT needs. With browser technology continuing to push the boundaries of what’s possible, the PageNodes experience will only become richer as we turn those new developments into new features.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

What will happen if I close pagenodes page? Will all the communications be lost?
For example No events will be logged to database?
It does appear there is a way to highlight/select the node components you want to save, then menu->export->clipboard to copy the code; you can import the code via menu->import into any Sheet.
But the data does not appear to be logged for the time-being.
Thanks for the feedback!
When the browser is closed, events aren’t firing, so no data would be logged to the internal storage (local indexeddb).
That said, we have been doing some work with the ServiceWorker API that will allow users to send messages from external sources that can wake up the app and kick off a flow with the message data.
