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 🙏

React Native (New Architecture) bindings for Kavach Shield Engine.

Version License Platform Support

TL;DR

The React Native SDK provides ultra-fast JSI bindings to the native iOS and Android Kavach Shield Engine libraries.

Who should use it: Mobile engineers building cross-platform React Native apps who need hardware-backed biometrics and device fingerprinting.

Quickest way to get started:

npm install @rajeev02/kavach-react-native
cd ios && pod install

Table of Contents

(For global architecture, CI/CD, and security guidelines, see the Root README)

Overview

Technical Value: Leverages React Native's New Architecture (JSI / TurboModules) for zero-latency execution of cryptographic functions and biometric scanning directly from the native thread.

Features

| Feature | Description | Status | | ------- | ----------- | ------ | | TurboModules | Synchronous JSI execution avoiding the RN Bridge. | Stable | | Native Biometrics | Triggers FaceID (iOS) and BiometricPrompt (Android). | Stable | | Hardware Attestation | Reads Secure Enclave / Keystore properties natively. | Stable |

Compatibility Matrix

| Component | Supported Version | | :--- | :--- | | React Native | 0.73.x+ (New Architecture enabled) | | iOS | iOS 13.0+ | | Android | Min SDK 24+ |

Quick Start

Install

npm install @rajeev02/kavach-react-native

Configure

Link the native dependencies (if not using autolinking):

cd ios && pod install

Usage

Basic Usage

import { KavachRN } from '@rajeev02/kavach-react-native';

async function authenticate() {
  const result = await KavachRN.promptBiometrics("Confirm Payment");
  if (result.success) {
    // Proceed with payment
  }
}

Troubleshooting

  • Build Failures (iOS): Ensure pod install succeeded and that you are opening the .xcworkspace (not the .xcodeproj).
  • Build Failures (Android): Ensure you are using Gradle 8.0+ and JDK 17.
