money-encoder

Money encoder/decoder for protocol buffers

Example using mafintosh/protocoll-buffers

// traveller.proto
syntax = "proto2";

/* 
 * money isn't a real protobuf type, but protocol-buffers
 * knows how to encode/decode it since we pass it the money-encoder
 */

message wallet {
  optional money dollars = 0;
  optional money pesos = 1;
}

message traveller {
  required wallet wallet;
}

var protobuf = require('protocol-buffers')
var fs = require('fs')
var money = require('wallet-encoder')
var proto = fs.readFileSync(__dirname + '/wallet.proto')

// initialize protobuf and teach it how to encode/decode money
var messages = protobuf(proto, { encodings: { money: money } })

var traveller = {
  wallet: {
      dollars: 20.45
    , pesos: 235.67
  }
}

var buf = messages.entry.encode(traveller)
console.log(buf)

var w = messages.entry.decode(buf)
console.log(w)

Output

<Buffer 02 0a 00 fd 07 00 00 00 10 5c 00 00>
{ wallet: { dollars: 235.68, pesos: 235.67 } }
