protobuf-decode

Protobuf-decode

Javascript version protobuf decoder. Aim: light-weight, file size no larger than 5kB. Just decode simple structs.

Usage

We don't use .proto file, instead, we use a JSON formatted message description, basically the same as protobuf.js json format.

To decode a protobuf, first you need to use build() method to build the message package, this step will automatically detect embedded message dependencies and handle them for furthur use.

Then, you can pick your message from the result of first step to actually decode a byte array. This process shoud be like:

import protobuf from './protobuf';
import msgPackage from './msg_struct';

// build the messages package
const builders = protobuf.build(msgPackage),
      builder = builders.HistoryData;

// decode using message builder
protobuf.decode(byteArr, builder)
