Ethereum web3.js is a JavaScript API that allows developers to interact with the Ethereum blockchain.
The web3.js library is used by dapps (decentralized applications) to connect to Ethereum nodes, submit transactions, and read data from the blockchain.
The web3.js library is available on GitHub and is MIT licensed.
It can be used in both Node.js and web browsers. .
The web3 object in web3.js contains methods for interacting with the Ethereum blockchain.
These include methods for reading data from the blockchain, submitting transactions, and interacting with smart contracts.
NOTE: WARNING: Ethereum Web3 Js is a powerful and complex programming language that is used to create decentralized applications (or “Dapps”) on the Ethereum blockchain. It is important to note that coding with Ethereum Web3 Js requires a good understanding of the language and its associated technologies, as well as an understanding of blockchain technology in general. Without proper knowledge of these topics, you may run into errors or unintended consequences when coding with Ethereum Web3 Js. It is highly recommended that you do your research before embarking on any project involving Ethereum Web3 Js.
The web3 object also provides access to the Ethereum network (either Mainnet or a testnet), account information, and node information.
The web3 object can be accessed in a Node.js application using the require() function:
var Web3 = require(‘web3’);
In a browser, the web3 object is available via the window object:
window.addEventListener(‘load’, async () => {
// Modern dapp browsers.
if (window.ethereum) {
window.web3 = new Web3(ethereum);
try {
// Request account access if needed
await ethereum.enable();
// Acccounts now exposed
web3.eth.sendTransaction({/* .
*/});
} catch (error) {
// User denied account access.
}.
