npm install --save machinetalk-protobuf

Usage

See examples. If you want to try these examples, be sure to first run npm install in this repository.

Encoding

var machinetalkProtobuf = require('machinetalk-protobuf');
var messageContainer = {
  type: machinetalkProtobuf.message.ContainerType.MT_PING
};
var encodedMessageContainer = machinetalkProtobuf.message.Container.encode(messageContainer);

This results in a buffer that starts with 0x08 0xd2 0x01.

Decoding

var machinetalkProtobuf = require('machinetalk-protobuf');
var encodedBuffer = new Buffer([0x08, 0xd2, 0x01]);
var decodedMessageContainer = machinetalkProtobuf.message.Container.decode(encodedBuffer);

This results in a messageContainer like the one defined in Encoding.

JavaScript (Browser)

CDN usage

<script src="//cdn.rawgit.com/machinekit/machinetalk-protobuf/VERSION/dist/machinetalk-protobuf.js"></script>

With VERSION replaced by a valid tag or just master for testing the latest master build.

Encoding

var messageContainer = {
  type: machinetalk.protobuf.message.ContainerType.MT_PING
};
var encodedMessageContainer = machinetalk.protobuf.message.Container.encode(messageContainer);

This results in a buffer that starts with 0x08 0xd2 0x01.

Decoding

var encodedBuffer = new ArrayBuffer([0x08, 0xd2, 0x01]);
var decodedMessageContainer = machinetalk.protobuf.message.Container.decode(encodedBuffer);

This results in a messageContainer like the one defined in Encoding.
