Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v3.3.0-pure.1

Published

JavaScript SDK for interacting with the Symbol and NEM blockchains.

Readme

@nemnesia/symbol-sdk

npm version license

Node.js・ブラウザ・React Native対応のSymbol公式SDK移植版(symbol-sdk公式 ベース)


概要

このパッケージは symbol-sdk 公式リポジトリをベースに、Node.js だけでなくモダンブラウザ(ES2020以降)、さらに React Native でも動作するよう再構成した TypeScript/JavaScript SDK です。

主な変更点

暗号処理の依存先をNode.js組込から@noble系へ移行

  • 乱数生成: Node.js標準のcrypto.randomBytesから、@noble/hashes/utils.jsrandomBytesへ変更
  • HMAC生成: Node.js標準のcrypto.createHmacから、@noble/hashes/hmac.jshmacへ変更
  • RIPEMD160: Node.js標準のripemd160から、@noble/hashes/legacy.jsripemd160へ変更 BIP32/BIP39関連
  • ニーモニック生成: 従来のbitcore-mnemonicから、@scure/bip39へ変更
  • MessageEncoder
    • encode/tryDecode など暗号化部分を非同期メソッド化
  • Buffer完全排除

インストール

Node.js、ブラウザ、React Native いずれの環境でも利用可能です。

# npm
npm install @nemnesia/symbol-sdk
# pnpm
pnpm add @nemnesia/symbol-sdk
# yarn
yarn add @nemnesia/symbol-sdk

クイックスタート

import { PrivateKey } from '@nemnesia/symbol-sdk';
import { SymbolFacade } from '@nemnesia/symbol-sdk/symbol';

// ランダムな秘密鍵生成
const privateKey = PrivateKey.random();

// アカウント生成
const facade = new SymbolFacade('testnet');
const account = facade.createAccount(privateKey);

console.log('privateKey:', account.keyPair.privateKey.toString());
console.log('publicKey :', account.publicKey.toString());
console.log('address   :', account.address.toString());

TypeScriptでもそのまま利用できます。

注意事項

  • 公式symbol-sdkと一部APIや挙動が異なる場合があります。
  • 暗号処理や依存パッケージの違いにより、完全な互換性は保証されません。
