Particle cloud backend implementation

Hello,

I was wondering if any of the Particle cloud backend implementation (particle.js implementation) is open sourced?

Thanks,
Kevin

None of the back-end implementation is open-source.

There is an open-source demo of the cloud-side device protocol for the Photon and P1 (CoAP over TCP with AES encryption) in the unmaintained SparkServer. Newer devices use CoAP over DTLS, which is a standard.
