Getting Started

The ethers.js library is a compact and complete JavaScript library for Ethereum.

Installing in Node.js

Install the ethers.js library from your project directory:

/home/ricmoo/my-project> npm install --save ethers


JavaScript (ES3)
var ethers = require('ethers');
JavaScript (ES5 or ES6)
const ethers = require('ethers');
JavaScript (ES6) / TypeScript
import { ethers } from 'ethers';

Including in Web Applications

For security purposes, it is usually best to place a copy of this script on the application’s server, but for a quick prototype using the Ethers CDN (content distribution network) should suffice.

<!-- This exposes the library as a global variable: ethers -->
<script src=""
