module.exports = function (proto, opts) {
  if (!opts) opts = {}
  if (!proto) throw new Error('Pass in a .proto string or a protobuf-schema parsed object')

  var sch = (typeof proto === 'object' && !Buffer.isBuffer(proto)) ? proto : schema.parse(proto)

  // to not make toString,toJSON enumarable we make a fire-and-forget prototype
  var Messages = function () {
    var self = this

    compile(sch, opts.encodings || {}).forEach(function (m) {
      self[m.name] = flatten(m.values) || m
    })
  }

  Messages.prototype.toString = function () {
    return schema.stringify(sch)
  }

  Messages.prototype.toJSON = function () {
    return sch

protocol-buffers-schema

No nonsense protocol buffers schema parser written in Javascript

npm install protocol-buffers-schema

Usage

First save the following file as example.proto

syntax = "proto2";

message Point {
  required int32 x = 1;
  required int32 y=2;
  optional string label = 3;
}

message Line {
  required Point start = 1;
  required Point end = 2;
  optional string label = 3;
}

The run the following example

var fs = require('fs')
var schema = require('protocol-buffers-schema')

// pass a buffer or string to schema.parse
var sch = schema.parse(fs.readFileSync('example.proto'))

// will print out the schema as a javascript object
console.log(sch)

Running the above example will print something like

{
  syntax: 2,
  package: null,
  enums: [],
  messages: [{
    name: 'Point',
    enums: [],
    messages: [],
    options: {},
    fields: [{
      name: 'x',
      type: 'int32',
      tag: 1,
      required: true,
      repeated: false,
      options: {}
    }, {
      name: 'y',
      type: 'int32',
      tag: 2,
      required: true,
      repeated: false,
      options: {}
    }, {
      name: 'label',
      type: 'string',
      tag: 3,
      required: false,
      repeated: false,
      options: {}
    }]
  }, {
    name: 'Line',
    enums: [],
    messages: [],
    options: {},
    fields: [{
      name: 'start',
      type: 'Point',
      tag: 1,
      required: true,
      repeated: false,
      options: {}
    }, {
      name: 'end',
      type: 'Point',
      tag: 2,
      required: true,
      repeated: false,
      options: {}
    }, {
      name: 'label',
      type: 'string',
      tag: 3,
      required: false,
      repeated: false,
      options: {}
    }]
  }],
  options:{}
}
