Values missing if set to 0 and after converting toJson()

[iamterryclark]

Hello,

I am running some tests to convert our google-protobuf setup to protobuf-es

we have a WebSocket receiving / requesting data between C++ and JavaScript

i have registered the types i am using and passing that to my unpack function.

I noticed that inside the message JSON after converting the incoming binary function that any value that was set to 0 goes missing from the json object

event.data is an ArrayBuffer so it needs to be converted to a UInt8Array it seems

 const data = new Uint8Array(event.data)
 const message = myMessagePacket.fromBinary(data);
 
 ...
 
//later i convert to json
 
const myMessage = message.anyTypedData.unpack(registry);

functionToPassBackToMyStateManmagement(myMessage.toJson())
 

I noticed printing myMessage.toJson() is missing any value which is set to 0.

Hi Terry, this is expected behavior for fields that do not track presence. The field is also omitted when serializing to binary.

You can pass the option emitDefaultValues: true as an argument to toJson. The option is documented here.

Thank you for the reply. I hadn't seen that.

Looking forward to have this library implemented on our app, in place of google-protobuf
