安装

yarn add @airx/proto
# or
npm i --save @airx/proto

Encode/Decode 示例

const { Message } = require('@airx/proto');

// example code
const message = Message.create({ did: 'device1' });
const buffer = Message.encode(message).finish();
const decoded = Message.decode(buffer);

google.protobuf.Timestamp 示例

const timestamp = require('@airx/proto/timestamp');
const timestampObject = timestamp.set( new Date() );
// 返回 JSON Mapping 对象
const timestampFromObject = timestamp.get(timestampObject);
// 返回 Date Object
