Re: [protobuf] Javascript with Protobuf FileDescriptorSet and what is equivalent to DynamicMessage.parse(FileDescriptor, byte[] payload) ?

['Adam Cozzette' via Protocol Buffers]

Unfortunately the Javascript implementation doesn't support this kind of
DynamicMessage functionality. In Javascript you can only really manipulate
a protocol buffer if you have already built the generated code with protoc.

[protobuf] Javascript with Protobuf FileDescriptorSet and what is equivalent to DynamicMessage.parse(FileDescriptor, byte[] payload) ?

[Vijay Balakrishnan]

Hi,
Newbie to protobuf and pardon my naivete on this topic.

I would like to use protoc --descriptor_set_out=out.desc  -js_out=
import_style=commonjs,error_on_name_conflict,binary:.  mymessage.proto

I have code to upload this out.desc to my server to S3. using out.desc as I 
want multiple clients to upload their separate descriptor files to me
I have a node.js micro-service and want to be able to handle a byte[] 
payload using this out.desc. The micro-service receives a key along with 
the byte[] payload. I use the key on the backend to identify the out.desc 
filedescriptor to use.
In Java, I can use DynamicMessage.parse(FileDescriptor, byte[] payload) to 
do this after identifying the relevant desc file using a key to connect the 
client to the desc file.

How do i do this in javascript or node.js ?

TIA,
Vijay
