Let's make a #CBOR Payload Formatter for #TheThingsNetwork
#CBOR works great for compressing Sensor Data sent to #TheThingsNetwork ... But each app needs to decode the CBOR Sensor Data
Thanks to #TheThingsNetwork Payload Formatter, we can decode CBOR in the cloud ... And send JSON to the apps!
Payload Formatters are plain old JavaScript functions (not Node.js) ... That will run on #TheThingsNetwork Servers to decode our #LoRaWAN Message Payload

Here's a sample Payload Formatter that decodes the Message Payload received by #TheThingsNetwork
"cbor-js" is a plain old JavaScript Decoder for #CBOR ... Let's port this to #TheThingsNetwork as Payload Formatter
Remember to handle JavaScript Errors in our #CBOR Payload Formatter for #TheThingsNetwork
https://github.com/lupyuen/cbor-the-things-network/blob/master/cbor.js#L410-L441
Paste our CBOR Payload Formatter JavaScript into #TheThingsNetwork at Application > Payload Formatters > Uplink
https://www.thethingsindustries.com/docs/integrations/payload-formatters/javascript/
#TheThingsNetwork now returns the Decoded #CBOR Payload to all our apps: Prometheus, Grafana, Roblox, ...
Decoding #CBOR Sensor Data in #TheThingsNetwork with a Payload Formatter ... All shall be explained in this (short) article
