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 🙏

🔐 Library for verifying secure digital signatures of HTTP requests

Description

touchmark-server is a library for verifying secure digital signatures of HTTP requests. It protects your API from unauthorized requests, timing attacks, and signature replay and duplicate requests.

Installation

npm install touchmark-server

Purpose

  • Authenticate incoming API requests
  • Prevent forged requests
  • Validate frontend and mobile app requests
  • Validate signature

Usage

1. Initialization

import FingerprintCore from 'touchmark-server';

const fingerprint = new FingerprintCore({
  applyFingerprint: true,
  appSecretKeyList: ['YOUR_SECRET_KEY'],
  allowedIpList: ['127.0.0.1'],
  whiteListPath: ['/api/health'],
  assetsPathPrefixList: ['/static'],
  headerSignatureKey: 'x-request-uuid'
});

2. Express.js Integration

const isValidSignature = (req, res, next) => {
  const { method, path, headers } = req;
  const isValid = fingerprint.decrypt({ method, path, headers });
  if (fingerprint.isFilterInit && !isValid.status) {
    return res.status(401).json({ error: 'Invalid request', details: isValid.message });
  }
  next();
};
app.use(isValidSignature);

3. Native HTTPS Server Integration

const server = https.createServer(options, (req, res) => {
  const method = req.method || '';
  const path = new URL(req.url || '', `https://${req.headers.host}`).pathname;
  const headers = req.headers;
  const isValid = fingerprint.decrypt({ method, path, headers });
  if (fingerprint.isFilterInit && !isValid.status) {
    res.writeHead(401, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify({ error: 'Invalid request', details: isValid.message }));
    return;
  }
  // ...your logic
});

Configuration Fields Description

  • applyFingerprint — enable signature validation (true/false)
  • appSecretKeyList — array of HMAC secret keys
  • allowedIpList — array of allowed IP addresses
  • whiteListPath — array of paths that do not require signature
  • assetsPathPrefixList — array of static resource prefixes
  • headerSignatureKey — header name containing the signature

Additional

For frontend signature generation, use touchmark-client.

Опис

touchmark-server — бібліотека для перевірки цифрових підписів HTTP-запитів. Захищає API від несанкціонованих запитів, таймінг-атак та повторного використання підпису та дублюваних запитів.

Встановлення

npm install touchmark-server

Для чого потрібна

  • Перевірка автентичності запитів
  • Захист від підроблених запитів
  • Валідація фронтенд, мобільних додатків
  • Валідація підпису

Використання

1. Ініціалізація

import FingerprintCore from 'touchmark-server';

const fingerprint = new FingerprintCore({
  applyFingerprint: true,
  appSecretKeyList: ['ВАШ_СЕКРЕТНИЙ_КЛЮЧ'],
  allowedIpList: ['127.0.0.1'],
  whiteListPath: ['/api/health'],
  assetsPathPrefixList: ['/static'],
  headerSignatureKey: 'x-request-uuid'
});

2. Інтеграція з Express.js

const isValidSignature = (req, res, next) => {
  const { method, path, headers } = req;
  const isValid = fingerprint.decrypt({ method, path, headers });
  if (fingerprint.isFilterInit && !isValid.status) {
    return res.status(401).json({ error: 'Недійсний запит', details: isValid.message });
  }
  next();
};
app.use(isValidSignature);

3. Інтеграція з HTTPS сервером

const server = https.createServer(options, (req, res) => {
  const method = req.method || '';
  const path = new URL(req.url || '', `https://${req.headers.host}`).pathname;
  const headers = req.headers;
  const isValid = fingerprint.decrypt({ method, path, headers });
  if (fingerprint.isFilterInit && !isValid.status) {
    res.writeHead(401, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify({ error: 'Недійсний запит', details: isValid.message }));
    return;
  }
  // ...ваша логіка
});

Опис конфігурації

  • applyFingerprint — чи вмикати перевірку підпису (true/false)
  • appSecretKeyList — масив секретних ключів для HMAC
  • allowedIpList — масив дозволених IP-адрес
  • whiteListPath — масив шляхів, які не потребують підпису
  • assetsPathPrefixList — масив префіксів для статичних ресурсів
  • headerSignatureKey — назва заголовка, де міститься підпис

Додатково

Для фронтенду використовуйте touchmark-client для генерації підпису.
