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 🙏

Readme

slp-mutable-data

This is a JavaScript library that is packaged with Browserify, to make it accessible to both browser-based and node.js-based JavaScript apps. It allows Bitcoin Cash (BCH) wallets to create, read, and update tokens that have both mutable (changeable) and immutable (unchangeable) data. Data is stored off-chain, and available via IPFS.

This library implements this PS002 specification for token mutable data. It follows a series of pointers on the Bitcoin Cash blockchain to retrieve a JSON file from the IPFS network. This is a way to track changing data associated with a token. It's a way for video game characters, supply chain items, and other unique changing assets to be represented by a token. This library is an extension of the Cash Stack.

Installation

Here are different ways to consume this library in your app, depending on the environment you are using.

Browser

<script src="https://unpkg.com/slp-mutable-data"></script>

Node.js

npm install --save slp-mutable-data

// ESM import
import { SlpMutableData } from 'slp-mutable-data'

// CommonJS require
const { SlpMutableData } = require('slp-mutable-data')

Examples

Examples are provided in the examples directory:

  1. Create Immutable Data
  2. Create Mutable Data
  3. Create a Token with both mutable and immutable data.
  4. Update Mutable Data.
  5. Get Token Data.

Overriding Defaults

This library has default IPFS gateways and servers that can be overridden, so that devs are not forced to depend on any one specific infrastructure. Here is an example of overridding all the servers this library depends on:

this.slpMutableData = new SlpMutableData({
  wallet,
  ipfsGatewayUrl: 'p2wdb-gateway-678.fullstack.cash', // IPFS Gateway
  serverURL: 'https://p2wdb.fullstack.cash', // P2WDB server (see p2wdb.com)
  pinServer: 'https://p2wdb-pin.fullstack.cash' // P2WDB Pinner Cluser
})
