# nodejs with protobuf demo

## introduction

    use node_module protobufjs to process protobuf protocol data

## protobuf format data

```protobuf==

package cover;

message helloworld {

    message helloCoverReq {

        required string name = 1;

    }

    message helloCoverRsp {

        required int32 retcode = 1;

        optional string reply = 2;

    }

}

```

## use protobufjs to load proto and decode, encode data

```javascript==

const protobuf = require('protobufjs');

const builder = protobuf.loadSync("./protos/cover.helloworld.proto");

const HelloCoverReq = builder.lookupType("cover.helloworld.helloCoverReq");

const HelloCoverRsp = builder.lookupType("cover.helloworld.helloCoverRsp");

// create object 

const hCRspObj = HelloCoverRsp.create({

    retcode: 0,

    reply: 'reply from udp server'

});

// encode to Buffer

const msg = HelloCoverRsp.encode(hCRspObj).finish();

// decode from buffer

HelloCoverReq.decode(message)

```
