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 🙏

Installation

Make sure you also have the web3 library

npm install eth-wallet-connector

yarn add eth-wallet-connector

Examples

Below examples are with React, however this library does not depend on React and will work with any Javascript web Frontend

Metamask

import React from 'react'
import { connectMetamask, getWeb3 } from 'eth-wallet-connector'

export default function ConnectComponent() {
  const handleConnectMetamask = async () => {
    const result = await connectMetamask();

    if (result) {
      // connected

      const web3 = getWeb3(); // this retrieves the web3 instance from the wallet

      const accounts = await web3.eth.getAccounts();
    }
  }

  return (
    <button onClick={handleConnectMetamask}>Connect Metamask</button>
  )
}

Eagerly connect with Metamask

Try to connect with metamask and see if a connection was done before, this is useful when user refreshes the page or visits your Dapp again

import React, { useEffect } from 'react'
import { eagerlyConnectMetamask, getWeb3 } from 'eth-wallet-connector'

export default function ConnectComponent() {
  useEffect(() => {
    const connectEagerlyMetamask = async () => {
      const result = await eagerlyConnectMetamask();

      if (result) {
        // connected

        const web3 = getWeb3(); // this retrieves the web3 instance from the wallet

        const accounts = await web3.eth.getAccounts();
      }
    }

    connectEagerlyMetamask();
  }, [])

  return (
    <div>This is the landing page</div>
  )
}

WalletConnect

import React from 'react'
import { connectWalletConnect, getWeb3 } from 'eth-wallet-connector'

export default function ConnectComponent() {
  const handleConnectWalletConnect = async () => {
    const result = await connectWalletConnect();

    if (result) {
      // connected

      const web3 = getWeb3(); // this retrieves the web3 instance from the wallet

      const accounts = await web3.eth.getAccounts();
    }
  }

  return (
    <button onClick={handleConnectWalletConnect}>Connect Wallet Connect</button>
  )
}
