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 🙏

crypto.getRandomValues for React Native

A small implementation of crypto.getRandomValues for React Native. This is useful to polyfill for libraries like uuid that depend on it.

Installation

npm install react-native-get-random-values
npx pod-install

💡 If you use the Expo managed workflow you will see "CocoaPods is not supported in this project" - this is fine, it's not necessary.

Usage

This library works as a polyfill for the global crypto.getRandomValues.

// Add this line to your `index.js`
import 'react-native-get-random-values'

Now you can use uuid or other libraries that assume crypto.getRandomValues is available.

import { v4 as uuid } from 'uuid'

console.log(uuid())

API

crypto.getRandomValues(typedArray)

The crypto.getRandomValues() method lets you get cryptographically strong random values. The array given as the parameter is filled with random numbers (random in its cryptographic meaning).

To guarantee enough performance, implementations are not using a truly random number generator, but they are using a pseudo-random number generator seeded with a value with enough entropy. The PRNG used differs from one implementation to the other but is suitable for cryptographic usages. Implementations are also required to use a seed with enough entropy, like a system-level entropy source.

  • typedArray - Is an integer-based TypedArray, that is an Int8Array, a Uint8Array, an Int16Array, a Uint16Array, an Int32Array, or a Uint32Array. All elements in the array are going to be overridden with random numbers.

Returns the typed array that was passed in.
