Protobuff with NodeJS on Windows

I would like to send a simple TCP message to a device (Karotz) from NodeJS Script on Windows.

  • NodeJS correctly installed working
  • The TCP connection is working.
  • Here is my .proto file (http://wiki.karotz.com/index.php/Voos-message.proto)
  • I will compile it in .desc using google protoc

I don’t know how to create my message to send it to the device?

But I do not understand how to install it on windows. It seems complicated because of the native library.

Is there a dead simple javascript library that reads a .desc schema and creates a message? Without native code or complex material?

If you use Node.js, it’s easier to just use the NPM version of the protobuf library, it will build it for you if you have a C ++ compiler on your computer:

> npm install protobuf

To create your own message and analyze the existing message:

 var Schema = require('protobuf').Schema; var readFile = require('fs').readFileSync; var schema = new Schema(readFile(__dirname+'/Voos-message.desc')); var VooMsg = schema['net.violet.voos.message.VoosMsg']; // Convert to protobuf format var msg = VooMsg.serialize({id:1, correlationId: 'hello'}); // Read it back var outMsg = VooMag.parse(msg);

The protobuf library works very well and is easy to use. But if you want a clean version of JS, look at: ProtoBufJS
