I browsed a bit the open-day slides and like the fact realtime API’s are in the roadmap. I really think this would benefit many parts of the ERPNext user experience.
One questions though. I see you’re looking at node.js here. I just want to drop a warm recommendation for good old twisted (https://twistedmatrix.com/) and for pure python websockets, the ultra stable and ultra tested (http://autobahn.ws).
- First, it’s python (feels in line with frappe).
- Second, my experience building things using twisted is that things runs for months to years without problems or restarts (so why look anywhere else).
- Third, twisted is perfect for hardware integrations like very easily being able to deal with various interfaces like barcode readers via serial-ports, hooking up ethernet/IP based label-printers and so on.
It’s also perfect for building machine-to-machine bridges, say in case of “satellite installs” / some specific station in a workshop or factory that needs 2-way realtime sync with an ERPNext instance. A distributed state-machine using Twisted TCP-sockets (or websockets) doesn’t require many lines of code to get up and running.
If serious throughput & speed is needed, pypy is well tested with twisted & autobahn.
Just a thought!
