What it does

Wagmi provides a set of reactive primitives to build Ethereum applications, simplifying the process of interacting with the Ethereum blockchain

Install / run

npm install wagmi

When to use it

•When building a dApp that requires real-time updates from the Ethereum blockchain
•When needing to simplify complex Ethereum smart contract interactions
•When creating an application that requires robust error handling for Ethereum transactions

Quick start

1Import wagmi in your project: `import { createClient } from 'wagmi';`
2Create a wagmi client: `const client = createClient({ provider: 'https://mainnet.infura.io/v3/YOUR_PROJECT_ID' });`
3Use the `useAccount` hook to get the current account: `import { useAccount } from 'wagmi'; const { address } = useAccount();`
4Use the `useBalance` hook to get the current balance: `import { useBalance } from 'wagmi'; const { data: balance } = useBalance({ address });`
5Subscribe to blockchain events using `useBlockNumber`: `import { useBlockNumber } from 'wagmi'; const { data: blockNumber } = useBlockNumber();`

Ready-to-paste prompt

Get the current Ethereum block number: `import { createClient } from 'wagmi'; const client = createClient({ provider: 'https://mainnet.infura.io/v3/YOUR_PROJECT_ID' }); client.getBlockNumber().then((blockNumber) => console.log(blockNumber));`

Heads up: Make sure to replace `YOUR_PROJECT_ID` with your actual Infura project ID, as the Infura API requires a valid project ID to function correctly
