When building with web3.js, you use Node.js to run your code. Tools such as MetaMask, Ganache, and Truffle provide wallets, local networks, and smart contract testing environments. Hardhat and Foundry offer advanced smart contract testing and deployment. You also use Ethereum nodes (such as Geth or Infura) to connect web3.js apps to Ethereum networks. Etherscan provides blockchain data that web3.js can access to read transactions and contracts.
