The library you can rely on,
For binary serialization and deserialization,
In Node, Deno, and the Web environment,
Which is simple and yet performant.

Features

• Performant
• Easy to use
• Full TypeScript support
• Super extensible
• 99% tree-shakable
• Zero dependencies (small footprint)
• Runs in Node, Deno and browsers
• No eval() or Function() by default

Performance Comparison with other tools in Node (ops/sec)

Installation

Expand for more details.

In the terminal with NPM

npm i sirdez

Or with Yarn

yarn add sirdez

In the code with ES Modules

import * as sd from "sirdez";

or with CommonJS

const sd = require("sirdez");

In HTML with UMD

<script src="https://cdn.jsdelivr.net/npm/sirdez/dist/sirdez.umd.js"></script>

In an ES module script (statically)

import * as sd from "https://cdn.jsdelivr.net/npm/sirdez/dist/sirdez.es.js";

In an ES module script (dynamically)

const sd = await import(
  "https://cdn.jsdelivr.net/npm/sirdez/dist/sirdez.es.js"
);

In code (statically)

import * as sd from "https://deno.land/x/sirdez/mod.ts";

In code (dynamically)

const sd = await import("https://deno.land/x/sirdez/mod.ts");

Usage

Creating a simple SerDes.

const person = sd.use(
  sd.struct({
    name: sd.string(sd.utf8, sd.uint8),
    age: sd.uint8
  })
);

const bytes = person.toBytes({
  name: "Bob",
  age: 23
});

const samePerson = person.fromBytes(bytes);

console.log({ bytes, samePerson });

Using TypeScript utilities

type Person = sd.GetType<typeof person>;

const bob: Person = {
  name: "Bob",
  age: 23
};

Roadmap

• Support decorators for schema
• msgpack extension mechanism using classes
• Better support for protocol buffers
• Avro-Sirdez schema transpiler

Known Issues

• msgpack becomes very slow for large arrays (help wanted for optimizing it! 🙏)
