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 🙏

Web3.js Tolar Hashnet Plugin

Web3.js plugin for interacting with Tolar Hashnet network and accounts.

Prerequisites

Installation

npm install @tolar/web3-plugin-tolar

Usage

Installing Peer Dependencies

# Install web3j
npm install web3
# Install web3-eth-accounts
npm install web3-eth-accounts

NOTE The Tolar plugin incorporates account handling that is a thin wrapper around web3-eth-accounts, so its dependency is necessary.

Registering the Tolar plugin with a web3.js instance

First, we create a web3js object and set the provider to the local Tolar Hashnet network.
The next step is to register the Tolar Hashnet plugin in accordance with the web3JS plugin guide.

const web3 = new Web3("http://127.0.0.1:8200/jsonrpc");
web3.registerPlugin(new TolarPlugin());

Build Project

# Build
npm run build
# Lint
npm run lint
# Test
npm run test

Examples
