@wagmi/core
Advanced tools
@wagmi/core is a library for building web3 applications with ease. It provides a set of hooks and utilities for managing Ethereum-based interactions, such as connecting to wallets, fetching blockchain data, and executing transactions.
Connect to Wallet
This feature allows you to connect to a user's Ethereum wallet using various connectors like MetaMask. The code sample demonstrates how to use the `connect` function to establish a connection.
const { connect } = require('@wagmi/core');
async function connectWallet() {
const { data, error } = await connect({ connector: new InjectedConnector() });
if (error) console.error(error);
else console.log('Connected:', data);
}
Fetch Blockchain Data
This feature allows you to fetch data from the blockchain, such as account balances. The code sample shows how to use the `useAccount` and `useBalance` hooks to retrieve and log the balance of the connected account.
const { useAccount, useBalance } = require('@wagmi/core');
function fetchBalance() {
const { data: accountData } = useAccount();
const { data: balanceData } = useBalance({ addressOrName: accountData?.address });
console.log('Balance:', balanceData);
}
Execute Transactions
This feature allows you to execute transactions on the Ethereum blockchain. The code sample demonstrates how to use the `useSendTransaction` hook to send 1 ETH to a specified address.
const { useSendTransaction } = require('@wagmi/core');
function sendTransaction() {
const { sendTransaction } = useSendTransaction();
sendTransaction({
request: {
to: '0xRecipientAddress',
value: '1000000000000000000', // 1 ETH in wei
},
}).then((result) => console.log('Transaction sent:', result));
}
Ethers.js is a library for interacting with the Ethereum blockchain and its ecosystem. It provides utilities for connecting to Ethereum nodes, managing wallets, and interacting with smart contracts. Compared to @wagmi/core, ethers.js is more low-level and requires more manual setup for common tasks.
Web3.js is a collection of libraries that allow you to interact with a local or remote Ethereum node using HTTP, IPC, or WebSocket. It provides functionalities for sending transactions, interacting with smart contracts, and more. Web3.js is one of the oldest and most widely used libraries for Ethereum development, but it can be more cumbersome to use compared to @wagmi/core.
