jserial v0.1.10

jserial

Compressed and Fast JSON Serializer

Using Libraries

msgpackr, @evan/wasm/lz4

Quick Start

Installation

npm install jserial --save

Basic Usage

const JSONSerializer = require("jserial");
const serializer = new JSONSerializer();

const json = {
  hello: "world",
};
const serialized = serializer.serialize(json);
const deserialized = serializer.deserialize(serialized);
if (deserialized instanceof Error) {
  // Deserialize Error
}

Msgpack Custom Extension

const JSONSerializer = require("jserial");
class CustomClass {};
JSONSerializer.addExtension({
    class: CustomClass,
    type: 1, // 1 ~ 100
    read(instance) {
        return instance.customData;
    },
    write(data) {
        const customClass = new CustomClass();
        customClass.customData = data;
        return customClass;
    }
});

Using Msgpackr Dictionary

const JSONSerializer = require("jserial");
const serializer = new JSONSerializer("namespace");
// or
const serializer = new JSONSerializer({ namespace: "namespace" });

const json = {
  hello: "world",
};
const serialized = serializer.serialize(json);
const deserialized = serializer.deserialize(serialized);

Using simple En-Decoding (simple internal logic, sometimes fast than serialize)

const JSONSerializer = require("jserial");
const serializer = new JSONSerializer();

const json = {
  hello: "world",
};
const serialized = serializer.serializeSimple(json);
const deserialized = serializer.deserializeSimple(serialized);
