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 🙏

OPConnect

OPConnect is a powerful React component library for connecting a wallet to your dApp. It supports the most popular connectors and chains out of the box and provides a beautiful, seamless experience.

Features

  • 🔐 Simple Auth - Batteries included wallet connect and authentication.
  • 💡 TypeScript Ready — Get types straight out of the box.
  • 🌱 Ecosystem Standards — Uses top libraries such as wagmi.
  • 🖥️ Simple UX — Give users a simple, attractive experience.
  • 🌞🌚 Light/Dark/Auto Modes — Predesigned color themes.

and much more...

Packages

Quick Start

Get started with a OPConnect + wagmi + viem project by running one of the following in your terminal:

npm

npx create-react-app my-app --template cra-template-opconnect

yarn

yarn create react-app my-app --template cra-template-opconnect

pnpm

pnpm dlx create-react-app ./my-app --template cra-template-opconnect

Getting Started

OPConnect is the simplest way to integrate a connect wallet experience into your React.js web application. It comes with sensible defaults out of the box so you can focus on building.

1. Install

Install OPConnect and its peer dependencies:

npm install @otherpage/connect wagmi [email protected] @tanstack/react-query
  • Wagmi is a React Hooks library for Ethereum, this is the library you will use to interact with the connected wallet.

  • Viem is a TypeScript interface for Ethereum that performs blockchain operations.

  • TanStack Query is an async state manager that handles requests, caching, and more.

  • TypeScript is optional, but highly recommended.

2. API Keys

Sign In With Other Page (SIWOP)

If you intend to use Sign in With Other Page (SIWOP) to log users into your app, you will need to create a connect app in the Other Page Community Dashboard and set the require configuration. See: examples/nextjs-siwop/README.md for a list.

WalletConnect 2.0

OPConnect utilises WalletConnect's SDK to help with connecting wallets. If you wish to use WalletConnect 2.0, it requires a walletConnectProjectId which you can create quickly and easily for free over at WalletConnect Cloud.

3. Implementation

It is recommended to wrap your app within a new component that will help you set up OPConnect and its dependencies.

Start by creating a new component called Web3Provider. Here you will import the required providers and create a config using wagmi's createConfig method. OPConnect supplies a pre-configured getDefaultConfig function to simplify the process of creating a config.

Below is a simple example app using getDefaultConfig() to help you get started:

When using a framework that supports React Server Components, you will need to include the "use client" directive at the beginning of this file.

import { WagmiProvider, createConfig, http } from 'wagmi';
import { mainnet } from 'wagmi/chains';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { OPConnectProvider, getDefaultConfig } from '@otherpage/connect';

const config = createConfig(
  getDefaultConfig({
    // Your dApps chains
    chains: [mainnet],
    transports: {
      // RPC URL for each chain
      [mainnet.id]: http(
        `https://eth-mainnet.g.alchemy.com/v2/${process.env.NEXT_PUBLIC_ALCHEMY_ID}`
      ),
    },

    // Required API Keys
    walletConnectProjectId: process.env.NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID,

    // Required App Info
    appName: 'Your App Name',
  })
);

const queryClient = new QueryClient();

export const Web3Provider = ({ children }) => {
  return (
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
        <OPConnectProvider>{children}</OPConnectProvider>
      </QueryClientProvider>
    </WagmiProvider>
  );
};

Now that you have your Web3Provider component, you can wrap your app with it:

import { Web3Provider } from './Web3Provider';
import { ConnectButton } from '@otherpage/connect';

const App = () => {
  return (
    <Web3Provider>
      <ConnectButton />
    </Web3Provider>
  );
};

4. Connected Wallet Info

In a lot of use cases, you will want to access the connected wallet from OPConnect in order to be able to interact with it further. You can do so by using the different hooks, such as useAccount, from wagmi (a OPConnect dependency).

In the previous example above we wrapped our app with a  top-level. Before utilizing any wagmi hook, make sure the components you build are mounted under this provider.

Below is a simple example component that utilizes the useAccount hook to access connection state and the connected wallet address:

import { useAccount } from 'wagmi';

// Make sure that this component is wrapped with OPConnectProvider
const MyComponent = () => {
  const { address, isConnecting, isDisconnected } = useAccount();
  if (isConnecting) return <div>Connecting...</div>;
  if (isDisconnected) return <div>Disconnected</div>;
  return <div>Connected Wallet: {address}</div>;
};

5. Sign In With Other Page (SIWOP)

Sign in With Other Page acts as a drop in replacement of other forms of authentication for your app. Using SIWOP enables your users to login once across all of your apps and bring their avatars and profile data with them.

Additional Build Tooling Setup

Some build tools require additional setup to work with ConnectKit.

Next.js

OPConnect uses WalletConnect's SDK to help with connecting wallets. WalletConnect 2.0 pulls in Node.js dependencies that Next.js does not support by default.

You can mitigate this by adding the following to your next.config.js file:

module.exports = {
  webpack: (config) => {
    config.resolve.fallback = { fs: false, net: false, tls: false };
    return config;
  },
};

Next.js App Router

If using Next.js App Router, or any framework that supports React Server Components, you will need to include the "use client" directive at the beginning of your Web3Provider file.

"use client"

...

export const Web3Provider = ({ children }) => {
  return (
    ...
  );
};
