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 🙏

Javascript implementation of CashID by Jonathan Silverblood

Quick Pitch

This is a convenient way to login and sign up to websites using Bitcoin Cash as your "identity".

Description

CashID is an open protocol that allows secure authentication based on the public key cryptography infrastructure that is currently present in the Bitcoin Cash ecosystem. Each user can prove to a service provider that they control a specific Bitcoin Cash address by signing a challenge request, as well as provide optional metadata.

Installation

grab from NPM

  npm i cashid

Usage

import CashID from 'cashid'; // or const CashID = require('cashid');

const cashid = new CashID();

// or if using your own server
// const cashid = new CashID(domain, path);
// domain = something.com  (no http prefix)
// path = /api/auth  (endpoint that will receive POST json data)

const uri = cashid.createRequest(action, data, metadata);

// action is an optional string, ie: 'login'
// data is an optional string, ie: 'newsletter' or '123-123-123'
// metadata is an optional object, ie:
//  {
//      required: {
//        identity: ['name', 'family'],
//        position: ['country'],
//        contact: ['email']
//      },
//      optional: {
//        identity: ['age', 'gender'],
//        position: ['city']
//      }
//  }

return uri;

// uri will look like

// cashid:example.com/api/auth?a=register&d=newsletter&r=i12p1c1&o=i45p3&x=142341090

with the uri, you can generate a QR code for the user to scan, or see a client side badger-wallet implementation

The identity manager would read the cashid uri, and send a JSON POST request to the endpoint.

You would validate the object on the server side and return true as the response if valid.

Available Methods

cashid.validateRequest(responseObject)

cashid.parseCashIDRequest(requestURI)

cashid.createRequest(action, data, metadata)
