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

Importing¶

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.

HTML¶

<!-- This exposes the library as a global variable: ethers -->
