web3-react VS useDApp

What are we building? Using hardhat, we will deploy a smart contract to the goerli testnet, this contract creates a token and also is able to send these tokens to other address. For the frontend we will use react, for the interaction with the smart contract we will use Metamask and web3-react. Finally, for the analytics of our dapp we will be using sumer.

web3-react

About the stack: - Typescript - Nextjs - TailwindCSS - Styled Components - Emotion - Twin.Macro (combining Styled Components with TailwindCSS) - NextI18Next integrated (wrong translationkeys result in compilation errors) - Web3React - Ethers - Redux Toolkit + Redux Observables (with hydration example) - Ramda among others

Make sure you have some understanding of HTML/CSS. Check out Automate The Boring Stuff to learn some Python and then check out Real Python to learn some Django for your backend stuff. From there you're going to want to learn Solidity and for that I suggest checking out Crypto Zombies. Then you can learn a JavaScript frontend framework like React which has cool packages for web3 like web3-react. I'm on mobile and probably butchered this but it should give you some idea.

Web3-React, a connecting framework for React and Ethereum, can help us with job 1 & 2. Web3-React is an open source framework developed Uniswap engineering Lead Noah Zinsmeister. (We will focus on job 1.)

Please note that @web3-react changes a little. @web3-react/injected-connector and @web3-react/walletconnect-connector are used here. But maybe we should update with @web3-react. Please find: https://github.com/NoahZinsmeister/web3-react

useDapp

There are other several libraries to create a web3 enviroment as: Rainbowkit || Wagmi || Scaffold-eth || useDApp || web3modal || Web3-UI

Something like https://usedapp.io for react/Js

You should also check out useDapp. It brings a lot more than connections but since you're writing a dapp anyway, it's gonna be useful

If you’re a react dev, take a look at useDApp to connect your front end to the blockchain. Good luck!

Check out useDApp - https://usedapp.io/ I'm using it for connecting to Harmony and its very straightforward to set up and utilize. (I'm not affiliated with useDApp in any way.)

Yeah, the whole login process was one of the major pains within this project. But I found a useful stack to implement it smoothly. First of all, I built the app using the "useDApp" lib (https://github.com/EthWorks/useDApp). This lib creates lots of great hooks to use, which integrates perfectly into the React framework. This lib provides a one-function-solution to login using browser wallets (activateBrowserWallet). But that's only half of the job. For all other users I am using the "WalletConnectConnector" lib from the great "web3-react" framework. This lib creates the frontend dialog and returns the chosen provider, which I forward to the "useDApp" library for the hooks and blockchain connection. Here is the main code for the login procedure: import { useEthers } from '@usedapp/core'; import { WalletConnectConnector } from '@web3-react/walletconnect-connector'; const walletconnect = new WalletConnectConnector({ rpc: { 1: process.env.REACT_APP_RPC_URL_1, 4: process.env.REACT_APP_RPC_URL_4 }, qrcode: true }) function WalletButton(props) { const { activateBrowserWallet, activate, deactivate, account } = useEthers(); useEffect(() => { const walletConnectSettings = localStorage.getItem("walletconnect"); if(walletConnectSettings) { if(JSON.parse(walletConnectSettings).connected === true) { activate(walletconnect); } } }, [activate]); const handleLogin = async () => { if(window.ethereum || window.web3) { activateBrowserWallet(); } else { activate(walletconnect); } } }
