Installation

npm i ezmsg-node

Features

• Tiny (~1KB minified and gzipped).
• Ready to use with Typescript (this library is written in Typescript actually).

Basic usage

// Import
import { BType, serialize, deserialize } from 'ezmsg-node';

// Define schema
const schema = {
  id: BType.U8,
  name: BType.STR,
  age: BType.U8,
  isMarried: BType.BOOL
};

// Define data
const data = {
  id: 1,
  name: 'John',
  age: 28,
  isMarried: false
}

// Serialize
const buffer = serialize(data, schema);
// buffer: <24 01 24 4a 6f 68 6e 1c 00>

// Deserialize
const result = deserialize(buffer, schema);

Array and Object type

// Import
import { BType, serialize, deserialize } from 'ezmsg-web';

// Define schema
const foodSchema = {
  id: BType.U8,
  name: BType.STR,
  price: BType.U32
};

const schema = {
  id: BType.U8,
  name: BType.STR,
  age: BType.U8,
  isMarried: BType.BOOL,
  favoriteFood: foodSchema,
  hatedFoods: [foodSchema]
};

// Define data
const data = {
  id: 1,
  name: 'John',
  age: 28,
  isMarried: false,
  favoriteFood: {
    id: 1,
    name: 'Banana',
    price: 100
  },
  hatedFoods: [{
    id: 2,
    name: 'Cabbage',
    price: 50
  }, {
    id: 3,
    name: 'Carrot',
    price: 75
  }]
}

// Serialize
const buffer = serialize(data, schema);

// Deserialize
const result = deserialize(buffer, schema);

Caveats

• There will be decimal errors when deserializing f32 and f64 values. It is recommended that you always round it when you are going to use the value.
