protobuf.js

Protobuf.js

This is an extremely lightweight, stripped down, ugly implementation of protocol buffers written specifically for use in making a Riak library. As such, it lacks support for many of the data types, and handles a few Riak specific fields in special ways (vclocks, for one). I will happily accept pull requests to make it more compatible with the full spec.

What it does:

• parses .proto files to build a schema (including imports) in a very very rough way
• encodes objects to buffers
• decodes buffers to objects
• supports the string/bytes and varint types

What it does not do:

• have full support for every directive in .proto files
• have support for any types other than varint or string/bytes
• make your breakfast

Usage

var protobuf = require('protobuf.js'),
    translator = protobuf.loadSchema('./riak_kv.proto');

var msg = translator.encode('RpbGetReq', { bucket: 'test', key: 'test' });
//msg will *only* contain the protobuf encoded message, *NOT* the full riak packet

var decoded = translator.decode('RpbGetResp', responsePacket);
//again, this will *only* decode the protobuf message. you have to remove the riak header yourself
